AB  - The paper presents the results of a three-year observation of Fusarium head blight (FHB) of small grains using two models: risk assessment from Pessl instruments disease model and the risk of appearance of FHB developed at Penn State University. Development of FHB was assessed on the wheat varieties Pobeda and NS40S which differ in earliness, awning and the level of resistance. Agricultural parameters were monitored at the locality of Rimski Šančevi in trials testing: sowing, the level of mineral nutrition and sowing density of eight wheat varieties, one spelt variety and one triticale variety. Calibration of models was carried out in 16 localities in Serbia, during 2008, 2009, 2010 and 2011. For each locality GPS coordinates were taken, growth stage were determined, preceding crop and tillage system were denoted. Model calibration was performed in the following locations: Rimski Šančevi (Novi Sad), Sremska Mitrovica, Zrenjanin, Pančevo, Sombor, Subotica, Vršac, Valjevo, Požarevac, Kragujevac, Niš, Pirot, Leskovac, Zaječar and Negotin. According to flowering date it is possible for each variety to assess the risk and level of risk at a given point of view. The combination of the two models proved to be very reliable in predicting the occurrence of FHB of wheat.

Razvoj fuzarioze klasa praćen je na sortama Pobeda i NS40S koje su različite po ranostasnosti, osjatosti i stepenu otpornosti. Agrotehnički parametri praćeni su u lokalitetu Rimski Šančevi u ogledima u kojima se ispituje: rok setve, nivo mineralne ishrane, gustina setve kod osam sorti ozime pšenice, jedne sorte tipa spelta pšenice i jedne sorte tritikalea. Kalibracija modela vršena je u 16 lokaliteta na teritoriji Srbije, tokom 2008, 2009, 2010. i 2011. godine. Za svaki lokalitet obeležene su GPS koordinate, određena je fenofaza useva, utvrđeni predusev i sistem obrade zemljišta. Kalibracija modela vršena je u sledećim lokalitetima: Rimski Šančevi (Novi Sad), Sremska Mitrovica, Zrenjanin, Kikinda, Pančevo, Sombor, Subotica, Vršac, Valjevo, Požarevac, Kragujevac, Niš, Pirot, Leskovac, Zaječar i Negotin. Prema datumu cvetanja moguće je za svaku sortu izvršiti procenu rizika i stepen rizika u datom trenutku posmatranja.

AB  - The risk of disease and pest damages to agricultural crops has increased significantly as a result of climatic changes. Climate change could have positive, negative or no impact on field and vegetable crops diseases. However, it can be foreseen that in some regions, under very strong temperature-precipitation change 'signal', losses induced by increased infection potential of present and/or new diseases could be significant. The paper includes analysis of the severity of diseases caused by parasitic fungi in small grains, sunflower, sugar beet, potato and tomato. Climatic changes have resulted in the dominance of pathogens that require higher temperatures for their development or are better able to adapt to drought conditions. This is the reason why small grains fungal diseases of the genus Fusarium and Septoria spp. have dominant role, causing significant damage. Because the causal agents of sunflower spots develop very well and rapidly at high temperatures, global warming has caused these diseases to become more severe in Serbia and the damages they cause have increased. Furthermore, today, due to increased temperatures, the successful control of the Cercospora leaf spot requires twice as many chemical treatments as in the previous period. Until recently, one to two treatments (1.5 on average) during the growing season were needed in order to control C. beticola, whereas today two to four treatments are required. The early blight of tomato and potato has in recent years become a major disease and has been causing significant damages in these two crops. The increasing severity is attributed to the increase in temperature and the greater frequency of years having warm and dry summers.

AB  - In the province of Vojvodina, biotic and abiotic factors were identified that may lead
to significant yield losses. Their prevalence was directly correlated with climatic changes.
There is a strong correlation between the causal agents of powdery mildew and leaf
rust, because the occurrence of one of the two pathogens prevents the other from
occurring as a major outbreak. The present chapter introduces the concept of the Uredo-
Teleuto Spore Coefficient (UTC). In Puccinia coronata, this coefficient shows the
rapidity of transition from the uredo to the teleuto stage under the influence of
temperature on reproductive organs of the pathogen. Based on the UTC values (0-1 ), five
U/T categories were established. The most genotypes (54, or 22.6%) had UTC=l, i.e. a
complete transition of P. corona/a from the uredo stage to the teleuto one. Climatic
changes have resulted in the dominance of pathogens that require higher temperatures for
their development or are better able to adapt to drought conditions (Septoria spp.,
Pyrenophora tritici-repentis, P. teres, Rhynchosporium secalis). At phenophase 29-30, a
correlation was found between the number of pycnides fonned and infection severity by
Septoria tritici in the first seven leaves. The correlation was complete in the variety
Simonida (r=0.93) and very high in the variety Pobeda (r=0.88). The main causal agents
of grain destruction in wheat are FHB and bunt, which may result in total yield losses.
Abiotic factors that may significantly reduce grain yields are temperature conditions
causing problems in the early stages of small grains development or stress at yield
formation. The development of cultivars resistant to parasitic fungi is a very important
measure of their control. Small grains cultivars for planting should be adapted and chosen
based on resistance to abiotic and biotic factors, while the breeding strategy should be
oriented towards developing genotypes adapted to stress factors.

AB  - Analyzed in the paper were the effects of genotype, fertilizer application and microclimate on nectar production and availability, bee attendance and sunflower seed yields. Four sunflower hybrids (Velja, NS-H-45, NS-H-111 i NS-H-702) and four fertilization treatments were analyzed. Disc flower corolla length and nectar content were studied in the hybrids and their parent lines. The monitoring of bee visitation at flowering was done on nine occasions every day. Nectar content and seed yield per head were determined. Weather conditions were also recorded at observation time. The flower nectar content differed significantly among the genotypes, ranging from 2 53 mg/20 flowers (Velja) to 15.57 mg/20 flowers (Ha-98B). The highest nectar content (7.36 mg/20 flowers) was found in the control treatment and the lowest (6.67 mg/20 flowers) in the 100:100:100 treatment. The largest bee attendance was recorded in NS-H-111 and the 150:150:150 treatment and the lowest in Velja and the 100:100.100 treatment. Corolla length in the treatments ranged from 9.11 mm (control) to 9.23 mm (100:100:100), while in the genotypes it ranged between 7.95 mm in Ha-26B and 11.14 mm in CMS-3-8B. The longest corollas were found in flowers whose pistils had not yet emerged (9.51 mm). Significant differences in yield were found among the hybrids as well as treatments. Bee attendance peaked at 25°C air temperature and 43.5% relative humidity. Bee presence was at its highest at 9.00 h.

Dužina krunice kod varijanti đubrenja kretala se od 9,11 mm (kontrola), do 9,23 mm (100:100:100), a kod genotipova od 7,95 mm (Ha-26B), do 11,14 mm (CMS-3-8B). Najduže krunice registrovane su kod cvetova kod kojih tučkovi još nisu bili izašli (9,51 mm). Utvrđene su značajne razlike u prinosu između hibrida, a takođe i između pojedinih varijanti đubrenja. Maksimalna poseta pčela zabeležena je pri temperaturi vazduha od 25°C i relativnoj vlažnosti vazduha od 43,5%. Najveća poseta registrovana je u 9 časova.",

AB  - Effects of genotype, fertilization and microclimate on visitation by pollinators and yield of sunflower were analyzed in the course of 2001 in a stationary field trial established at Rimski Šančevi experiment field. We analyzed four sunflower hybrids (Velja, NS-H-45, NS-H-111 and NS-H-702) grown in four fertilization variants. Bee visitation was monitored during flowering, making nine counts per day. Nectar content and weather parameters were observed at the same time. Seed yield per head measured after harvest. Significant yield differences were established among the hybrids as well as among the fertilization variants. Nectar content significantly differed among the hybrids (3.8 - 8.9 mg/20 flowers), and the fertilization variants (5.0 - 7.5 mg/20 flowers). Differences in bee visitation frequency observed among the hybrids and fertilization variants were in close association with the ranking of the hybrids for nectar content. Air temperature had a higher influence on bee visitation than relative air humidity. The influence of wind was insignificant. The daily dynamics of bee visitation showed one or two peaks, depending on the dynamics of flowering of individual hybrids.
AB  - Izvršena je analiza uticaja genotipa, đubrenja i mikroklimata na posetu pčela i prinos suncokreta. Ispitivanja su obavljena na Rimskim Šančevima, na stacionarnom ogledu, u 2001. godini. Ispitivana su 4 hibrida suncokreta (Velja, NS-H-45, NS-H-111 i NS-H-702), na 4 varijante đubrenja. Praćenje posete pčela tokom perioda cvetanja, tokom dana vršeno je u 9 navrata. Utvrđen je sadržaj nektara i prinos semena po glavi kao i pojedini vremenski činioci u vreme opažanja. Utvrđene su značajne razlike u prinosu između hibrida, a takođe i između pojedinih varijanti đubrenja. Sadržaj nektara u cvetu značajno se razlikovao između pojedinih hibrida (3,8 - 8,9 mg/20 cvetova), i varijanti đubrenja (5,0 - 7,5 mg/20 cvetova). Poseta pčela se razlikovala između pojedinih hibrida i varijanti đubrenja, a rang hibrida bio je isti kao i kod sadržaja nektara. Temperatura vazduha pokazala je jači uticaj na posetu pčela od relativne vlažnosti vazduha dok vetar nije pokazao značajan uticaj. Dnevna dinamika posete imala je jedan ili dva maksimuma u zavisnosti od vremena cvetanja pojedinih hibrida.

AB  - A land-air parameterization scheme (LAPS) describes water vapour, heat and momentum transfer between the land surface and the atmosphere. The scheme is designed as a software package, which can be run as part of an atmospheric, hydrological or ecological model, or as a stand-alone model that operates with seven prognostic variables and 16 morphological and physiological input parameters. Such large number of parameters provides reliable simulation of diurnal courses of meteorological elements inside the crop. In this paper, for simulating the diurnal course of air temperature inside a sunflower field, the LAPS scheme has been used. The results obtained are compared with the results of micrometeorological measurements of a sunflower experimental field of the Oil Crops Department at Rimski Sancevi (Yugoslavia) using data sets from 18 July to 24 July, 1998. The LAPS scheme was compared with two other surface schemes using canopy air temperature data derived from measured air temperature above a maize field at an experimental site in De Sinderhoeve (The Netherlands) for 18 August, 8 September, and 4 October 1988.
