AB  - Sowing is affected by numerous factors, and thus high-quality sowing is a very important task for agricultural engineers and managers of profitable agricultural production. The primary purpose of sowing is placing seeds at proper depths and in-row spacings in well-prepared soil. Plant population particularly gives prominence to sowing as it directly affects the uniformity of plant growth and development. Soybean planting is especially dependent on the quality of planting for yield formation due to the significant vicinity of seeds. Provided all external factors of high-quality sowing are met, i.e. sowing conditions, the quality of sowing depends upon the planting mechanism. The following features of the planting mechanism are the most important: RPM of the seed disc, the travel speed of a seeder, and the values of gauge and vacuum pressure. This paper presents the results of sowing three different fractions of soybean seeds under laboratory conditions. The quality measurement of sowing was performed at different values of vacuum pressure and RPM of the seed disc. On balance, an increase in vacuum pressure results in improved sowing quality due to a stronger adherence of seeds to the seed disc. Lower values of vacuum pressure do not exert significant effects on the quality of sowing, regardless of the seed fraction. However, higher RPM of the seed disc entail an increase in the coefficient of variation. On the basis of the results obtained, a mathematical model for predicting changes in the coefficient of variation of sowing quality was developed using different operating parameters.

AB  - Good effectivenes of sunflower desiccation with hidraulyc sprayer is possible only with good nozzles choice. Results of reaserch shown in this paper are confirm that. Statistic analyse of date about yield are shown that there is important difference at statistical level in yield size with desiccation by nozzles LU 120-04 i AIXR 120-04 according yield size obtained with nozzles IDK 120-04 i IDKT 120-04. Also, important difference are present in yield size of control according desiccation treatment with nozzles LU 120-04, AIXR 120-04 i IDK 120-04. Percentage of moisture according statistical analyse shown important difference at statistical level only between treatmants with nozzles LU 120-04 i IDKT 120-04. Statistic analyse of oil percentage in seed did not show any important difference at statistical level between treatment with different nozzles and contol. Also there is no any important difference between different nozzles treatment. Results of this reaserch shown that it very important to choose good nozzles type for desiccation according crops and weather condition.
AB  - Efikasna desikacija suncokreta primenom klasičnih prskalica moguća je samo pravilnim izborom rasprskivača. Rezultati istraživanja u ovom radu su potvrdili da pravilan izbor rasprskivača ima značajan uticaj na prinos pri desikaciji suncokreta. Statistička obrada obadataka o visini prinosa, pokazakla je da postoji statistički značajna razlika u visini prinosa ostvarenog desikacijom rasprskivačima LU 120-04 i AIXR 120-04 u odnosu na visinu prinosa ostavarenu rasprskivačima IDK 120-04 i IDKT 120-04.

Analiza sadržaja vlage u vreme berbe pokazuje statistički značajnu razliku jedino između rasprskivača LU 120-04 i IDKT 120-04. Između svih ostalih rasprskivača i kontrole nema statistički značajne razlike. Statističkom analizom sadržaja ulja uočava se statistički značajna razlika između sadržaja ulja kod useva koji je tretiran različitim rasprskivačima i kontrole. Sa druge strane nema statistički značajne razlike između tretmana različitim rasprskivačima. U zavisnosti od stanja useva, kulture koja se tretira, tipa preparata treba odabrati odgovarajući tip rasprskivača kako bi krajnji rezultat primene preparata bio što bolji.

AB  - Oil seed rape is important culture for oil production. Oil seed rape vegetation started at the end of summer or at the beginning of autumn and finished at beginning of summer next year. During this vegetation it is necessary to protect oil seed rape against some insects like meligethes aeneus which cause damages and decrease of yield. In this paper it was analyze problems in oil seed rape protection against insects. Accent is on analyses of bio-efficacy and quality parameters by treatment with different type of nozzles. The most important quality parameters which was analyze in this paper is leaf coverage. Beside this research it was also analyzed transversal distribution of nozzles. Treating was done with application rate 200 l/ha and three different type of nozzles. The lowest leaf coverage was achieved with standard nozzles Lechler LU120-04, 36,79 %. Better coverage was achieved with nozzles IDK 120-04, 37,24 % and the best coverages of 44,64 % was reach with 'Twin Jet' IDKT 120-04 nozzles. It was not found any different in bio-efficacy by treatment with different type of nozzles, but because very low insects attack intensity this results should be take with reserve. Checking of transversal distribution shown that CV of different nozzles was between 4,86 % and 6,02 %, which is good, because permit level is 10 %.
AB  - Uljana repica je važna uljana kultura. Njena vegetacija počinje krajem leta i početkom jeseni, a završava se obično početkom leta naredne godine. Tokom vegetacije vrši se hemijska zaštita uljane repice u cilju suzbijanja sjajnika i repine pipe. U radu su dati rezultati istraživanja kvaliteta i biološke efikasnosti hemijske zaštite repice protiv sjajnika i repine pipe uz istovremenu analizu uniformnosti poprečne distribucije. Tretiranje je obavljeno sa normom od 200 l/ha i tri vrste rasprskivača na istoj parceli u istim uslovima. Kvalitet tretiranja je praćen analizom pokrivenosti. Najbolja pokrivenost od 44,64 % je ostvarena primenom Lechler Twin Jet IDKT 120-04 rasprskivača dok primena klasičnog injektorskog Lechler IDK 120-04 i standardnog rasprskivača Lechler LU 120-04 beleži gotovo identičnu pokrivenost od 37,24 % i 36,79 %. Analiza biološke efikasnosti nije dala nikakve razlike po pitanju primene različitih tipova rasprskivača, ali zbog izuzetno slabog intenziteta napada štetočina ove rezultate treba uzeti sa rezervom. Provera koeficijenta varijacije poprečne distribuciju je pokazala da je poprečna distribucija sva tri rasprskivača bila dobra i kretala se u intervalu od 4,86 % do 6,02 %, što su vrednosti manje od dozvoljenih 10 %.
