Effect of nitrogen on grain and soybean grain mass thousand

Abstract

In a three-year trial the influence of the applied nitrogen under previous crop and the inoculation of seeds by Nitragin (microbiological agent) on the yield and thousand grain weight of soybean was studied. Inoculation of seeds contributed to a statistically highly significant yield increase in three years, while the mass of a thousand seeds was statistically very significantly higher in the two years of research. Nitrogen rate of 100 kgha-1 lead to increased yield, and nitrogen applied in quantities of 200 kgha-1 reduced soybean seed yield. .

U trogodišnjem ogledu proučavan je uticaj azota primenjenog pod predusev i inokulacije semena mikrobiološkim preparatom Nitragin na prinos i masu hiljadu zrna soje. Inokulacija semena doprinela je statistički veoma značajnom povećanju prinosa u sve tri godine, dok je masa hiljadu semena bila statistički veoma značajno veća u dve godine istraživanja. Doze azota od 100 kg ha-1 dovode do povećanja prinosa, dok azot primenjen u količini od 200 kg ha-1 smanjuje prinos semena soje. .
