Abstract:
A field experiment was conducted to study the effect of different sources and levels of nitrogen, phosphorus and zinc on soil fertility status, nutrient uptake, yield and quality of soybean. The results revealed that, with increasing levels of nitrogen (60, 90 and 120 kg ha-1) and phosphorus (40, 60 and 80 kg ha-1) there was increase in soil available N and P2O5 with application of N:P2O5:K2O:ZnSO4 @ 120:80:40:25 kg ha-1 (T5). The nutrient uptake by soybean was also significantly higher at T5. The N, P, K and Zn uptake (seed + haulm) found to be 200.94, 27.89, 54.04 kg ha-1 and 195.45 g ha-1, respectively. The soybean seed yield (2159 kg ha-1) was also highest with T5. However, the yield was on par with T4 (2115 kg ha-1). With regard to quality parameters the crude protein (41.94%), oil percent (18.17%) and oil yield (392.18 kg ha-1) also followed the same trend as that of seed yield.
