Effect of N Fertilizer Application on Growth and Yield of Inoculated Soybean

The paper studied the effects of different nitrogen rates (0, 30, 60, 90 kg N/ha) on the soybean cultivar Proteinka, inoculated with the NS - Nitragin microbial fertilizer. Trials were set up at Backi Petrovac on a soil with no previous history of soybean cultivation. Samples of plant material were taken twice, once at soybean flowering and once at maturity. At flowering, the largest mass and length of the above-ground plant parts were recorded in the treatment with 60 kg N/ha, while the largest nodule number, mass and N content were obtained with 30 kg N/ha. The largest pod, grain numbers and grain mass and N content were produced by the inoculated treatment with no N added, and that was the treatment that produced the largest yield as well.
