The effect of genotype and growing seasons on yield and quality of oats on pseudogley soil

Oat is widely grown in Western Serbia and compared to other cereal crops reputed be better suited for production under marginal environments, including low fertility soils cool wet climates. To determine the effect of cultivar growing seasons on yield components oats two varieties were examined during three years, field experiment secondary agricultural-chemical school "Dr Đorđe Radić" Kraljevo. Trials arranged according a randomized scheme five replications. The following oat traits analyzed: grain yield, 1000-kernel weight, test weight plant height. was performed extremely acidic pseudogley soil. obtained results show high years certain parameters its quality. On average, highest 2 .879 t ha-1 variety Vranac. these studies indicate significant impact season quality oats, poor type, which often present Serbia. Grain shows tendency increase with higher total amount distribution precipitation critical stages development.
