Oil content in soybean seed in dependence of nitrogen applied

Abstract

This investigation is conducted to determine influence of different doses of nitrogen fertilizer applied under previous crop, on yield, oil and protein content in soybean karnel. The experiment was performed on the plot of the Institute of Field and Vegetable Crops in Rimski Sančevi, in four replications, during three years. The highest dose of nitrogen applied under previous crop (200 kgha-1) has contributed decrease of yield for all three years of research, decline of oil content and yield and increase of protein content in 2006. and 2007. year.

U trogodišnjem ogledu proučavan je uticaj različitih doza azotnih đubriva primenjenih pod predusev kukuruz, na prinos, sadržaj ulja i proteina u zrnu soje. Ogled je postavljen u četiri ponavljanja, na parceli Instituta za ratarstvo i povrtarstvo u Rimskim Sančevima. Najveće doze azota primenjenog pod predusev (200 kgha-1) doprinele su smanjenju prinosa u sve tri godine istraživanja, smanjenju sadržaja i prinosa ulja i povećanju sadržaja proteina u 2006. i 2007. godini.
