Impact of agrometeorological conditions on yield components in soybean

Abstract

This paper presents the results of two-year’s study of four soybean cultivars. The trials were located at the experimental field of Maize Research Institute "Zemun Polje". The aim of the work was to examine the agro meteorological impact on seed yield and yield components in soybean. Environmental conditions significantly influenced the examined traits, primarily number of seeds and seed weight per plant. Besides, there was significant impact on the plant height and 1000-seed weight, whereas no environmental effect was found number of nodes and number of pods per plant. The seed yield decreased in three cultivars during the extreme drought in year 2012., while cultivar Nena exhibited a greater drought tolerance.

U radu su predstavljeni rezultati dvogodišnjeg ogleda sa četiri sorte soje na lokaciji Zemun Polje, ogledno polje Instituta za kukuruz, u cilju ispitivanja uticaja agrometeoroloških uslova na prinos zrna i komponente prinosa kod soje. Vremenski uslovi značajno su uticali na ispitivana svojstva, prvenstveno na broj i masu zrna, potom na visinu stabla i masu hiljadu zrna, dok broj nodusa i broj mahuna nisu pokazali značajno variranje u odnosu na uslove. Smanjenje prinosa u ekstremno sušnoj 2012. godini zabeleženo je kod tri sorte, dok je sorta Nena ispoljila veću toleranciju na sušu.
