AB  - To address the growing demand for sugar, sugar beet production must be increased. However, conventional chemical fertilizers, essential for root growth and yield quality, are environmentally harmful due to factors like greenhouse gas emissions and organic pollution. To address this issue, we need to consider eco-friendly organic alternatives, such as FRASS, which is the residue from mealworm larval excrement. FRASS is rich in essential nutrients (ESN), including nitrogen (N), phosphorus (P), and potassium (K). In our study, we aim to explore the potential of FRASS as an environmentally innovative fertilizer for sugar beet production, given the increasing popularity of mealworm farming. In a field experiment, we compared the efficacy of pre-sowing fertilization on two sugar beet varieties using three different models of two fertilizer concentrations (N:P:K 80:60:40 & N:P:K 40:30:20 ): pure mealworm FRASS, a combination of FRASS and mineral fertilizer, and pure mineral fertilizer (NPK). Our goal was to maintain the same level of ESN between NPK fertilizers and FRASS.

AB  - Continuous advancements in plant breeding and the development of new hybrid varieties are occurring alongside the challenges posed by climate change. Consequently, there is an ongoing need to reassess agricultural practices. Fertilisation, particularly with nitrogen, plays an important part in plant production. Nitrogen is a critical element required in significant quantities for optimal crop growth, influencing the yield of various crops. However, it's important to acknowledge that nitrogen is a dynamic element, and substantial nitrogen reserves cannot be retained within the soil. Given the distinct requirements of sugar beet cultivation, where nitrogen not only impacts root yield but also profoundly influences root quality, it becomes important to improve fertilisation management. Therefore in our study we focused on assessing the effects of five different nitrogen fertiliser levels (40, 80, 120, 160, and 200 kg N/ha) on root yield and quality of two commercial sugar beet hybrids.

AB  - Sugar beet is the second most important source for the sugar industry, particularly important in temperate climate zones of Central, West, and East Europe. However, its production has declined recently due to various factors of which the most important are subsidy cuts and the spread of various plant diseases. In the Pannonian Plain (Slovakia, Hungary, Romania, and Serbia), a disease called rubbery taproot disease (RTD) has been observed for along time. The variability in RTD symptoms and the extent of damage it causes have made its detection quite challenging, often leading to misdiagnoses as other diseases. However, the identification of Candidatus Phytoplasma solani as the cause of RTD has resolved the issue of its diagnosis. The latest outbreak in Serbia has had a significant economic impact on sugar beet production, prompting an urgent response to aid the industry and growers. In our study, conducted during the 2022 and 2023 seasons, we assessed the susceptibility/tolerance of thirty registered sugar beet hybrids in Serbia, evaluating their impact on root yield and quality in naturally infected experimental fields.

AB  - The development of irrigation schedules based on water balance implies a study of daily plant water requirements. A properly selected irrigation method is also of most importance. The objective of this study was to find out how surface drip irrigation (SDI) and shallow subsurface drip irrigation (SSDI), as well as different ET-based irrigation scheduling for maize (reference evapotranspiration (ETo), pan evaporation (Eo), and local climatic coefficients (lc)), affect grain yield, water use efficiency (WUE), and yield response factor (Ky) of maize. The field experiments were conducted in Vojvodina, a northern part of the Republic of Serbia, on the calcareous gleyic chernozem soil, using a complete block design in three replicates in 2019–2021. The water balance method was used for irrigation scheduling. The nonirrigated treatment was used as a control. The yield in irrigation conditions was statistically higher as compared with the nonirrigated control variant. Concerning the tested parameters, especially the maize yield, reference evapotranspiration (ETo) should be  recommended as the most acceptable method for assessing maize evapotranspiration. Preference should be given to SSDI compared to SDI because the installation of laterals can be performed together with the sowing, which can ensure the uniform and timely emergence of plants. Based on the Ky coefficient of 0.71, it can be concluded that maize is moderately tolerant to water stress in Vojvodina’s temperate climate. The results can contribute to precise planning and efficient irrigation of maize in the region, implying high and stable yields.

AB  - Drip irrigation is gaining importance in mitigating the consequences of water scarcity even in regions with abundant rainfall. The transition from surface to subsurface drip irrigation is accompanied by numerous problems. To overcome these issues, shallow subsurface drip irrigation can be potentially used as an effective drought control tool that brings additional benefits compared to conventional surface drip irrigation techniques. This research investigated the effects of different calculations of daily crop water requirements, reference evapotranspiration (ETo), and pan evaporation (Eo) on the yield and water use efficiency of pepper irrigated with a surface and shallow subsurface drip irrigation system. The experiment was conducted in field conditions in the Vojvodina region, the northern part of Serbia. The irrigation scheduling was based on the water balance approach. The calculated evapotranspiration rate was about 400 mm for the pepper growing period, regardless of the calculation method. The highest yield of pepper and evapotranspiration water use efficiency was obtained on the Eo variant with surface drip irrigation. However, irrigation water use efficiency showed no statistical significance concerning the calculation of evapotranspiration and irrigation type. The results indicated that both calculation methods and irrigation types can be used in pepper production, but priority should be given to pan-evaporation-based calculation.

AB  - The study was aimed at determining the most suitable irrigation schedule program for hemp grown for fibers by using evaporation from the free water surface (Eo), measured by a Class A pan and related crop plant coefficient (Kc). The experiment, carried out in Vojvodina, a northern part of the Republic of Serbia, included three irrigation regimes: I1, I2, and I3 corresponding, respectively, to daily evaporation from an open water surface (Eo), two interrow spacings: RS1 (12.5 cm) and RS2 (25 cm), and topped (T) and not topped (NT) variants. The Kc values used for the calculation of daily evapotranspiration (ETd) were 0.42 for April and May and 1.00 (I1), 0.80 (I2), and 0.60 (I3) from June to the harvest. In addition, the nonirrigated (Io) control variant was also included in the trial. The dioecious fiber hemp variety Marina was used for the trials. Irrigation was carried out by a drip irrigation system and was scheduled based on the water budget method. It started when readily available water (RAW) in the soil layer of 0.4 m was completely depleted by the plants. In the first year of the study, irrigation did not influence the yield of hemp fiber, but in the second one, the best result was achieved for the irrigation variant I1. Interrow spacing did not have a statistically significant effect on both the hemp fiber yield and the quality. The topping of plants significantly decreased the yield of hemp, and it is not recommended when the hemp is cultivated for fibers. The quality of the hemp fibers was not influenced by irrigation, inter-row spacing, and topping. The rate of hemp evapotranspiration was in an interval of 312 mm (ETa) to 520 mm (ETm). The highest values of IWUE and ETWUE in both years and the bark yield in the first year were detected for the I3 irrigation variant, which suggested that the crop plant coefficient (Kc) of 0.6 could be recommended for the correction of Eo values in the calculation of the daily evapotranspiration of hemp (ETd) from June to August. The yield response factor (Ky) with values of 0.22 and 0.60 for the total growing season reveals that, in rainy years, hemp for fiber production could be grown without irrigation in the temperate climate of the Vojvodina region. However, such years are rare. Without doubt, irrigation of fiber hemp is recommended in the mentioned region in order to obtain high yields of good quality product.

AB  - Field experiment was conducted to study the effects of surface (SDI) and shallow subsurface drip irrigation (SSDI) on potato (Solanum tuberosum L.) tuber yield, evapotranspiration, water use efficiency (WUE), and yield response factor (Ky). The experiment was carried out under semiarid climatic conditions in the Vojvodina region in 2020. The trial was established as a block design and adapted to technical specifications of drip irrigation system. In addition, the nonirrigated, control variant was also included in the trial. Irrigation was scheduled on the basis of water balance method. Daily water used on plants evapotranspiration (ETd) was calculated by multiplying reference evapotranspiration (ETo) with crop coefficients (kc). Kc values were 0.5, 0.7, 1.1, 0.9, 0.7 from planting to emergence, early vegetative development, tuber initiation, tuber enlargement and senescence, respectively. The potato processing variety ‘Taurus’ was used for the experiment. Obtained results indicate a significant effect of irrigation on potato yield compared to the nonirrigated variant (38.33 t ha−1) but differences in the yield using the SDI (58.06 t ha−1) and the SSDI (61.15 t ha−1) were not significant. In the study period, seasonal evapotranspiration in irrigation conditions (ETm) and in rainfed control variant (ETa) was 478 mm and 319 mm respectively. IWUE values were 9.39, 10.85 kg m-3 and 27.64, 29.09 kg m-3 but ETWUE values were 12.40, 14.35 kg m-3 and 12.14, 12.79 kg m-3 for SDI and SSDI respectively. The seasonal yield response factor (Ky) of 1.03 and 1.12 for SDI and SSDI indicates that potato can be grown without irrigation in the temperate climate of Vojvodina.

AB  - The experiment with drip irrigated pepper was conducted at the Rimski Šančevi experimental field of the Institute of Field and Vegetable Crops in Novi Sad in 2019. The irrigation was scheduled on the basis of the water balance method. Two methods were used to compute the daily evapotranspiration of pepper (ETd): reference evapotranspiration (ETo) and evaporation from an open water surface (Eo). Crop coefficients (kc) and corrective coefficients (k) were used to convert ETo and Eo values into ETd. Kc and k were 0.3–0.4, 0.6–0.7, 0.9–1.1, 0.8–0.9 and 0.4, 0.7, 1.0 and 0.8 for initial stage, crop development, mid season, and late season, respectively. ETo was calculated by the Hargreaves equation. Eo values were measured by a Class-A pan located at a meteorological station near the experimental plot. Irrigation started when readily available water (RAW) in the 0.3 m soil layer was completely absorbed by plants. Differences in crop yield (Y) and irrigation water use efficiency (IWUE) obtained using Eo (42.58 t ha-1, 15.20 kg m-3) and ETo (40.78 t ha-1, 14.56 kg m-3) were not statistically different. Evapotranspiration rate was 364.2 mm and 337.3 mm in Eo and ETo variant, respectively. The fact that the differences in Y and IWUE between different calculations of ETd were not statistically significant indicates that both methods can be recommended for irrigation scheduling programs for pepper in the climatic conditions of the Vojvodina region. However, priority should be given to ETo due to the easy accessibility and reliability of data.
AB  - Navodnjavanje paprike sistemom kap po kap obavljeno je u Institutu za ratarstvo i povrtarstvo na oglednom polju Rimski Šančevi (Novi Sad) 2019. godine. Vreme zalivanja je određivano vodnim bilansom. Dve metode su korišćene za obračun dnevnog utroška vode na evapotranspiraciju paprike (ETd): referentna evapotranspiracija (ETo) i evaporacija sa slobodne vodene površine (Eo). Koeficijenti kulture (kc) i koeficijenti korekcije (k) korišćeni su za pretvaranje ETo i Eo vrednosti u ETd. Vrednosti kc i k bile su 0,3–0,4; 0,6–0.7; 0,9–1,1; 0,8–0,9 odnosno 0,4; 0,7; 1,0 i 0,8 za početak vegetacije, intenzivni porast, centralni deo vegetacije i kraj vegetacije. ETo je računata postupkom Hargrivsa (Hargreaves). Eo vrednosti su merene evaporimetrom klase A, postavljenim na meteorološkoj stanici u neposrednoj blizini ogledne parcele. Navodnjavanje je obavljano kada je lakopristupačna voda u sloju zemljišta do 30 cm bila utrošena od strane biljaka. Razlike u prinosu (Y) i produktivnosti utrošene vode navodnjavanjem (IWUE) korišćenjem Eo (42,58 t ha-1, 15,20 kg m-3) i ETo (40,78 t ha-1, 14,56 kg m-3) nisu bile statistički značajne. Vrednosti evapotranspiracije u periodu vegetacije paprike bile su 364,2 mm odnosno 337,3 mm na varijantama obračuna Eo i ETo. Činjenica da nisu utvrđene statistički značajne razlike u vrednostima Y i IWUE ukazuje da se obe metode mogu koristiti u obračunu ETd u realizaciji racionalnog zalivnog režima paprike u klimatskim uslovima Vojvodine. Međutim, prednost zbog dostupnosti podataka ipak treba dati postupku ETo.

AB  - Intensive crop cultivation systems require continuous monitoring of irrigation water quality as well as the control of physical and chemical soil properties. In view of the ongoing climate change and a dramatic decrease in soil organic matter content, the use of low quality irrigation water and its adverse effects on soil, cultivated plants and irrigation equipment must not be overlooked. The aim of this paper was to evaluate general quality of irrigation water from the different water intake sources in the Vojvodina Province. The paper presents the results of irrigation water quality, collected during 2018 and 2019. The research included 140 irrigation water samples obtained from three different intake structures which collect water from wells, canals or reservoirs. Water quality was assessed using the following parameters: pH value, electrical conductivity (EC), total dissolved solids (TDS), ionic balance, sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) value. Water quality diagram given by the US Salinity Laboratory (USSL) and FAO guidelines for interpretation water quality for irrigation was used. Additionally, the Nejgebauer classification for irrigation water, developed specifically for the area of Vojvodina, was used as a third classification. Based on the results of mineralization of the irrigation water, the following values of the observed parameters were determined: average pH of the analyzed water samples were 7.89, ranged from 7.14 to 9.01, while electrical conductivity values ranged from 0.10 to 3.50 dS/m, with an average of 0.85 dS/m. TDS analysis resulted in a wide range of values, from 112 mg/l to 2,384 mg/l, with an average of 529,22 mg/l. SAR values varied between 0.04–16.52 with a satisfactory average of 1.97.  The USSL water classification produced similar results as FAO classification and RSC index <0, indicating that 57% of investigating samples are without concerns for irrigation use. Whereas, Nejgebauers classification and RSC index 0–1.25 shows that over 75% of analyzed samples are suitable and safe for irrigation and soil properties. Since the quality of irrigation water significantly affects plant productivity, as well as determines the chemical and physical properties of agricultural land, monitoring of water quality for irrigation is of high importance
AB  - U intenzivnim sistemima gajenja biljaka, pored kontrole fizičkih i hemijskih osobina zemljišta, neophodno je vršiti i kontinuirano praćenje kvaliteta vode za navodnjavanje. U svetlu nadolazećih klimatskih promena, kao i zabrinjavajućeg opadanja sadržaja organske materije, ne smeju se zanemariti i nepovoljne posledice primene vode neodgovarajućeg kvaliteta na navodnjavano zemljište, gajene biljke i opremu za navodnjavanje. U radu su prikazani rezultati kvaliteta vode koja se koristi za navodnjavanje, prikupljeni tokom 2018. i 2019. godine. Istraživanje je obuhvatilo 140 uzoraka vode iz razli­ čitih vodozahvata poreklom iz površinskih bunara, kanalske mreže i akumulacija za navodnjavanje. Za ocenu kvaliteta vode analizirani su sledeći parametri: pH vrednost, elektroprovodljivost (EC), suvi ostatak, jonski bilans, kao i koeficijent adsorpcije natrijuma (SAR) i vrednost rezidualnog natrijum-karbonata (RSC).

abstract = "Intensive crop cultivation systems require continuous monitoring of irrigation water quality as well as the control of physical and chemical soil properties. In view of the ongoing climate change and a dramatic decrease in soil organic matter content, the use of low quality irrigation water and its adverse effects on soil, cultivated plants and irrigation equipment must not be overlooked. The aim of this paper was to evaluate general quality of irrigation water from the different water intake sources in the Vojvodina Province. The paper presents the results of irrigation water quality, collected during 2018 and 2019. The research included 140 irrigation water samples obtained from three different intake structures which collect water from wells, canals or reservoirs. Water quality was assessed using the following parameters: pH value, electrical conductivity (EC), total dissolved solids (TDS), ionic balance, sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) value. Water quality diagram given by the US Salinity Laboratory (USSL) and FAO guidelines for interpretation water quality for irrigation was used. Additionally, the Nejgebauer classification for irrigation water, developed specifically for the area of Vojvodina, was used as a third classification. Based on the results of mineralization of the irrigation water, the following values of the observed parameters were determined: average pH of the analyzed water samples were 7.89, ranged from 7.14 to 9.01, while electrical conductivity values ranged from 0.10 to 3.50 dS/m, with an average of 0.85 dS/m. TDS analysis resulted in a wide range of values, from 112 mg/l to 2,384 mg/l, with an average of 529,22 mg/l. SAR values varied between 0.04–16.52 with a satisfactory average of 1.97.  The USSL water classification produced similar results as FAO classification and RSC index <0, indicating that 57% of investigating samples are without concerns for irrigation use. Whereas, Nejgebauers classification and RSC index 0–1.25 shows that over 75% of analyzed samples are suitable and safe for irrigation and soil properties. Since the quality of irrigation water significantly affects plant productivity, as well as determines the chemical and physical properties of agricultural land, monitoring of water quality for irrigation is of high importance, U intenzivnim sistemima gajenja biljaka, pored kontrole fizičkih i hemijskih osobina zemljišta, neophodno je vršiti i kontinuirano praćenje kvaliteta vode za navodnjavanje. U svetlu nadolazećih klimatskih promena, kao i zabrinjavajućeg opadanja sadržaja organske materije, ne smeju se zanemariti i nepovoljne posledice primene vode neodgovarajućeg kvaliteta na navodnjavano zemljište, gajene biljke i opremu za navodnjavanje. U radu su prikazani rezultati kvaliteta vode koja se koristi za navodnjavanje, prikupljeni tokom 2018. i 2019. godine. Istraživanje je obuhvatilo 140 uzoraka vode iz razli­ čitih vodozahvata poreklom iz površinskih bunara, kanalske mreže i akumulacija za navodnjavanje. Za ocenu kvaliteta vode analizirani su sledeći parametri: pH vrednost, elektroprovodljivost (EC), suvi ostatak, jonski bilans, kao i koeficijent adsorpcije natrijuma (SAR) i vrednost rezidualnog natrijum-karbonata (RSC). Uobičajeno je da se za ovu namenu koristi i klasifikacija prema Američkoj laboratoriji za slatine (USSL) kao i FAO procena kvaliteta vode za navodnjavanje. Za prostore AP Vojvodine razvijena je i Nejgebauerova klasifikacija koju smo takođe iskoristili za potrebe ocenjivanja. Na osnovu rezultata mineralizacije vode za navodnjavanje, utvrđene su sledeće vrednosti posmatranih para­ metara: prosečno izračunata pH vrednost analiziranih voda iznosila je 7,89 (min=7,14, max=9,01), vrednosti elektroprovodljivosti kretale su se u opsegu od 0,10 do 3,50 dS/m, sa prosečnom vrednošću 0,85 dS/m. U odnosu na vrednosti suvog ostataka, ispitivane vrednosti kretale su se u širokom opsegu, od 112 mg/l do 2.384 mg/l, s prosečnom vrednošću 529,22 mg/l. SAR vrednosti varirale su u opsegu 0,04–16,52 i zadovoljavajućim prosekom od 1,97. Klasifikacija prema Američkoj laboratoriji za slatine (USSL) pokazuje slične rezultate kao FAO klasifikacija i RSC indeks <0, ukazujući na to da 57% istraživanih uzoraka nije zabrinjavajuće za upotrebu u navodnjavanju.

U suprotnom, ako se ne utvrde statistički značajne razlike u prinosu, biće preporučen metoda izračunavanja pomoću Eo uz korišćenje k, zbog toga što se niže dnevne vrednosti utroška vode na evapotranspiraciju kukuruza mogu smatrati realnijim.
AB  - Analysis of irrigation scheduling of maize was done by using evaporation from the free water surface (Eo) and correction coefficients (k) and reference evapotranspiration (ETo) and crop coefficients (kc). The field experiment was carried out in 2018 on the Experimental field of the Institute of field and vegetable crops in the Department of alternative crops in Bački Petrovac. Maize hybrid NS 6030 was used for the trials. The plants were irrigated by a drip system with a lateral in each row with drippers spaced every 0.33 m. The drippers had an average flow rate of 2.0 l h-1 under the pressure of 70 kPa. The differences in yield of maize in the irrigation conditions were not statistically significant compared to the variant without irrigation because the year was favorable for maize production. As well there was no difference among variants used for the calculation of maize evapotranspiration. Maize evapotranspiration in the growing season (ETm) were 502 mm and 429 mm by using ETo and kc and Eo and k. Monthly values of ETm during the growing season were consistent regardless of the calculation methods, except in July. Values of ETm in July of 151 mm and 107 mm calculated by using ETo and kc and Eo and k methods as well the daily values which are correlated with the monthly have to be checked in irrigation scheduling of maize in the following investigation period. If statistical significance in maize yield between different methods of calculation is determined, the procedure with a higher yield has to be accepted in the calculation of ETm in the climatic conditions of the Vojvodina region. Otherwise, if the differences in maize yield are not statistical significance a method of calculation by using Eo and k will be recommended, because the value of the lower daily water used on maize evapotranspiration may be considered more realistic.

U istraživanjima je korišćen hibrid NS 3023 (FAO 390).Navodnjavanje je obavljeno sistemom kap po kap sa postavljenim lateralima u svakom redu, sa razmakom kapljača od 0,33 m i protokom 2,0 l h-1 pri radnom pritisku od 100 kPa. Vreme zalivanja je odredjivano vodnim bilansom. U ogledu je bila zastupljena i kontrolna, nenavodnjavana varijanta.Dnevni utrošak vode na evapotranspiraciju biljaka (ETd) računat je množenjem referentne evapotranspiracije (ETo) sa koeficijentima kulture (kc).

AB  - The experiment with irrigated maize was conducted at Bački Petrovac experimental field (N 45°19`, E 19°50`) of Institute of Field and Vegetable Crops in Novi Sad on the calcareous chernozem soil on the loess terrace in 2019. Maize hybrid NS 3023 (FAO 390) was used for the trials. The plants were drip irrigated with a lateral row per plant row with drippers spaced every 0.33 m. The drippers had an average flow of 2.0 l h-1 under a pressure of 100 kPa. The trial also included the non-irrigated (rainfed) control variant.Irrigation was scheduled on the basis of water balance method using reference evapotranspiration (ETo) and crop coefficients (kc). ETo was calculated by Hargreaves equation. Daily evapotranspiration (ETd) was computed using ETo and kc of 0.3-0.5, 0.7-0.85, 1.05-1.2, 0.8-0.9, and 0.5-0.6 for April-May, June, July August and September respectively. Leaf area index (LAI) was determined by multiplying the leaf length by the leaf width by a shape factor for maize 0.75. Irrigation water use (IWUE) was calculated from the ratio of maize yield in conditions with (Ym) and without irrigation (Ya) and irrigation water applied (I).The aim of the study was to determine the effect of drip irrigation on yield, water use efficiency and maize leaf area index.Irrigation significantly affected maize yield; yield of irrigated maize was 10894 kg ha-1, and of nonirrigated 7276 kg ha-1.The affect of irrigation on the leaf area index (LAI) was also significantand amounted to 4.07 m2 m-2 on irrigated variant and to 3.49 m2 m-2 on nonirrigated variant. Maize IWUE value of 2.41 kg m-3 was determined.

Daily evapotranspiration (ETd) was computed using ETo and kc of 0.3-0.5, 0.7-0.85, 1.05-1.2, 0.8-0.9, and 0.5-0.6 for April-May, June, July August and September respectively. Leaf area index (LAI) was determined by multiplying the leaf length by the leaf width by a shape factor for maize 0.75. Irrigation water use (IWUE) was calculated from the ratio of maize yield in conditions with (Ym) and without irrigation (Ya) and irrigation water applied (I).The aim of the study was to determine the effect of drip irrigation on yield, water use efficiency and maize leaf area index.Irrigation significantly affected maize yield; yield of irrigated maize was 10894 kg ha-1, and of nonirrigated 7276 kg ha-1.The affect of irrigation on the leaf area index (LAI) was also significantand amounted to 4.07 m2 m-2 on irrigated variant and to 3.49 m2 m-2 on nonirrigated variant. Maize IWUE value of 2.41 kg m-3 was determined.",

AB  - In the past few years, the symptoms of parsnip root rot (Pastinaca sativa L.)
have been more intense in production. This had a significant impact on the decrease
in the yield as well as the market value of the roots. Symptoms of rot are only
noticed during harvest. Continued development of the pathogen has been reported in
storage rooms, especially if the root is stored under uncontrolled conditions of
temperature and humidity. The aim of the study was the etiological study of root rot
in the open field and in storage rooms. Total of 56 root samples were collected in
the period 2016 – 2019 years. Isolation was performed by standard of
phytopathology procedure on PDA medium for fungi, MPA and CVP for bacteria.
After growth, a collection of isolates was formed, which was included in the
pathogenicity test. For the isolates that showed pathogenicity, the identification was
performed, the fungi were identified on the basis of morphological characteristics,
while the bacteria were studied for biochemical - physiological characteristics. Of
the 42 fungus and bacterial isolates collected, 37 caused similar symptoms of rot, on
artificially inoculated parsnip root, which was considered a pathogenic trait.
Fusarium spp. was isolated from the symptoms of dry rot on the leaf rosette
crossing, while Pectobacterium carotovorum subp. was isolated from the wet rot.
The symptom of rot, followed by the white mycelium of the fungus, was preliminary
indicated by the species Sclerotinia sclerotiorum, which was confirmed by isolation and identification. The dominant species in storage rooms which provide root rot
were Botrytis cinerea and Sclerotinia sclerotiorum. They were followed by Rhisopus
spp. and Penicillium spp. species, but they have not been proven pathogenic and
have been considered saprophytes. Root rot caused damage during harvest, as
insects too, which allowed pathogens and saprophytes to penetrate.

AB  - Imajući u vidu da je određivanje potreba biljaka za vodom u poljskim uslovima na eksperimentalnim parcelama, praćenjem dinamike vlažnosti zemljišta, zahtevno, predložene su brojne indirektne, obračunske metode. Uprkos brojnim merenjima i upoređenjima ostaje konstatacija da ne postoji takav indirektni metod koji bi imao univerzalnu primenu, već je svaki od njih lokalnog ili regionalnog karaktera.

Razlike u vrednostima utrošene vode na evapotranspiraciju kukuruza (ETm) obračunate pomenutim metodama za period vegetacije nisu bile posebno izražene. Međutim, znatno veće vrednosti ETm u julu, obračunate Hargreaves i Penman-Monteith metodama u odnosu na bioklimatski postupak primenom hidrofitotermičkih indeksa ukazuju na potrebu da se u narednom istraživačkom periodu ove metode provere u režimu navodnjavanja kukuruza.

AB  - Bearing in mind that the determination of the plant water requirements in field conditions at experimental fields by monitoring soil moisture is very demanding, a number of indirect, calculation methods have been proposed. Despite numerous measurements and comparisons it could be said that there is no such indirect method that would have universal application, but each of them is of local or regional character. In the analysis of maize water use on evapotranspiration (ETm) reference evapotranspiration methods (ETo) and plant coefficients (kc) were compared with the bioclimatic method using hydrophytothermic indices. Penman-Monteith method, which is reported by the FAO organization as a standard for the ETo calculation and the method of Hargreaves which is used by the Republic Hydrometeorological Service of Serbia, (RHMZS) were used for ETo calculation. Meteorological data for the calculation were taken from a meteorological station located on the experimental field of the Institute of Field and Vegetable Crops from Novi Sad in the Alternative Crops Department in Bački Petrovac.Differences in the values of water used on evapotranspiration of maize (ETm), calculated by the mentioned methods, for the growing period were not particularly great. However, higher values of the ETm in July calculated by Hargreaves and Penman-Monteith methods in relation to the bioclimatic method using hydrophytothermic indices of Bošnjak and Dragović point to the need to check those differences in a following investigation period. The statistical significance in maize yields obtained on different variants will recommend the most suitable method for the ETm maize calculation in agroecological conditions of the Vojvodina region.

AB  - Downy and powdery mildew are economically important diseases in all cultivated plant species. Pathogens Pseudoperonospora cubensis, Sphaerotheca fuliginea and Erysiphe cichoracearum are one of the limiting factors of successful melon production in agro-ecological conditions of Serbia. Cultivation of less susceptible and resistant genotypes against pathogens is the basis for successful melon production. Consequently, 30 melon genotypes were tested against the causative agent of downy mildew P. cubensis in the fi eld conditions. Also, the susceptibility of 4 lines originating from Ananas melon against causative agents of powdery mildew S. fuliginea and E. cichoracearum in greenhouse was determined. The lowest susceptibility to P. cubensis was expressed in the melon genotypes D11, D7, D13 in the fi rst and D30 in the second evaluation. The highest susceptibility to the mentioned pathogen was expressed in 8 genotypes in the fi rst and 15 genotypes in the second evaluation. In terms of the susceptibility of the tested lines to causative agent of powdery mildew, line A 2/1 was found as most resistant, and line A 3/4 as the most susceptible.

AB  - Ogled sa navodnjavanjem kukuruza izveden je 2018. godine na oglednom polju Instituta za ratarstvo i povrtarstvo iz Novog Sada u Odeljenju za alternativne biljne kulture u Bačkom Petrovcu, na zemljištu tipa karbonatni černozem. Kukuruz je navodnjavan sistemom kap po kap sa postavljenim lateralima u svakom redu, sa razmakom kapljača od 33 cm i protokom 2,0 l h-1 pri pritisku od 100 kPa. U ogledu su bile zastupljene dve varijante navodnjavanja, sa lateralima postavljenim na površini zemljišta (DI) i ukopanih ispod površine zemljišta na dubini 5-6 cm (shellow subsurface drip irrigation SSDI). Takođe, bila je zastupljena i kontrolna varijanta bez navodnjavanja. Vreme zalivanja je određivano metodom vodnog bilansa primenom koeficijenata kulture (kc) i referentne evapotranspiracije (ETo). Obračun ETo je rađen Hargreaves metodom. Za obračun dnevnog utroška vode na evapotranspiraciju korišćeni su koeficijenti kulture (maj 0,3-0,5, jun 0,7-0,85, jul 1,05-1,2, avgust 0,8-0,9, septembar 0,5-0,6). U ogledu je bio zastupljen hibrid NS 6030. Navodnjavanjem je dodato 55 mm vode. Prinos kukuruza na SSDI varijanti navodnjavanja (14,311 t ha-1) bio je signifikantno veći u odnosu na kontrolnu, nenavodnjavanu varijantu (12,846 t ha-1). Nisu utvrđene statistički značajne razlike u prinosu između DI (13,833 t ha-1) i kontrolne, nenavodnjavane varijante, a takođe ni između SSDI i DI varijante navodnjavanja. U uslovima navodnjavanja utrošak vode na evapotranspiraciju (ЕТm) iznosio je 502 mm, a na kontrolnoj varijanti bez navodnjavanja (ЕТa) 352 mm. Nisu utvrđene statistički značajne razlike u vrednostima iskorišćenosti vode dodate navodnjavanjem (Iwue) između SSDI varijante (2,66 kg m-3) i DI varijante navodnjavanja (1,80 kg m-3). Veći prinosi kukuruza i veće Iwue vrednosti na SSDI varijanti navodnjavanja u odnosu na DI varijantu, bez obzira na činjenicu da razlike nisu bile statistički značajne, ukazuju na potrebu daljih istraživanja imajući u vidu brojne prednosti navodnjavanja sa lateralima postavljenim neposredno ispod površine zemljišta (SSDI).
AB  - The experiment with irrigated maize was conducted at Bački Petrovac experimental field (N 45°19`, E 19°50`) of Institute of Field and Vegetable Crops in Novi Sad on the calcareous chernozem soil on the loess terrace in 2018. The plants were drip irrigated with a lateral row per plant row (0.7 m) with drippers spaced every 0.33 m. The drippers had an average flow of 2.0 1 h-1 under a pressure of 100 kPa. The experiment included two irrigation variants, with lateral placed on the soil surface (DI) and buried under the surface of soil at a depth of 5-6 cm (SSDI). The trial also included the non-irrigated (rainfed) control variant. Irrigation was scheduled on the basis of water balance method using reference evapotranspiration (ETo) and crop coefficients (kc). ETo was calculated by Hargreaves equation. Daily evapotranspiration (ETd) was computed using the reference evapotranspiration (ETo) and crop coefficient (kc) of 0.3-0.5, 0.7-0.85, 1.05-1.2, 0.8-0.9, and 0.5-0.6 for April-May, June, July August and September respectively. Maize hybrid NS 6030 were used for the trials. Water applied by irrigation was 55 mm. In the study, the yield of maize was statistically higher in SSDI irrigated variant (14,311 t ha-1) than in non-irrigated, control variant (12.846 t ha-1). The statistical differences were not detected between DI (13.833 t ha-1) and control variant and SSDI and DI variant of irrigation. Evapotranspiration rate in irrigation conditions (ETm) and in rainfed control variant (ETa) were 502 mm and 352 mm respectively. The values of irrigation water use efficiency (Iwue) obtained on SSDI (2.66 kg m-3) and DI (1.80 kg m-3) variant were not statistically different. Higher yields and Iwue values of maize obtained in SSDI irrigation variant compared to DI variant, regardless the fact that the differences were not statistically significant, indicate the need for further research because of the numerous advantages that irrigation with laterals placed shallow below the surface area have.

Kukuruz je navodnjavan sistemom kap po kap sa postavljenim lateralima u svakom redu, sa razmakom kapljača od 33 cm i protokom 2,0 l h-1 pri pritisku od 100 kPa.

AB  - The experiments showing the effect of drip irrigation on yield and evapotranspiration of fibre hemp (Cannabis sativa L.) were conducted at the experimental field of the Alternative Crops Department, Institute of Field and Vegetable Crops, Novi Sad, Serbia. Irrigation was based on the water balance method. Daily evapotranspiration (ETd) was computed from the reference evapotranspiration (ETo) and crop coefficient (kc) 0.5, 0.9 and 1.1 from sowing to 3-4 pair of leaves, from 3-4 pair of leaves to appearance of male flowers and from appearance of male flowers to the end of the season, respectively. ETo was calculated using Hargreaves equation. The irrigation depth was restricted to the soil depth of 0.4 m. In other words, irrigation started when readily available water in the soil layer of 0.4 m was completely depleted by plants. The irrigation rate was 30 mm at the beginning of the season, 40 mm in the middle of the season, and the amount of water added by irrigation was 320 mm during the entire season. Irrigation significantly affected the yield of fresh stems, fresh leaves, flowers and plant height, but not stem diameter and fibre content. Water used on evapotranspiration in irrigation conditions (ETm) was 470 mm, while in non-irrigated control variant it amounted to 129 mm (ETa). These preliminary results could be used as a good platform for hemp growers in the region, in terms of optimizing the use of irrigation water.
AB  - Eksperimentalna istraživanja o uticaju navodnjavanja kapanjem na prinos i evapotranspiraciju konoplje za vlakno (Cannabis sativa L.) su obavljena na oglednom polju Instituta za ratarstvo i povrtarstvo iz Novog Sada u Odeljenju za alternativne biljne vrste u Bačkom Petrovcu. Vreme zalivanja je određivano obračunom vodnog bilansa. Dnevne vrednosti utroška vode na evapotranspiraciju biljaka (ETd) su obračunate korišćenjem referentne evapotranspiracije (ETo) i koeficijenata useva (kc) čije su vrednosti 0,5, 0,9 i 1,1 za potperiode vegetacije konoplje od setve do porasta 3-4 lista, od 3-4 lista do pojave muških cvetova i od pojave muških cvetova do žetve. Referentna evapotranspiracija (ETo) računata je formulom Hargreaves-a. Zalivanje je obavljano kada su rezerve lakopristupačne vode u sloju zemljišta dubine 0,4 m bile iskorišćene. Zalivna norma je na početku vegetacije iznosila 30 mm, a od sredine vegetacije 40 mm. Navodnjavanjem je ukupno dodato 320 mm vode. Navodnjavanje je signifikantno uticalo na prinos sveže stabljike, svežih listova i cvetova i visinu biljaka, ali ne i na dijametar stabla i sadržaj vlakna. Utrošak vode na evapotranspiraciju biljaka u uslovima navodnjavanja (ETm) iznosio je 470 mm, a u uslovima bez navodnjavanja (ETa) 129 mm. Preliminarni rezultati istraživanja mogu biti korišćeni kao dobra osnova za proizvođače konoplje u regionu, u smislu racionalnog korišćenja vode za navodnjavanje.
