Though soybean is a leguminous crop, it responds to fertilizer N besides P and K requirement. In general, N application increases the P uptake. Phosphorus fertilization to soybean favourably enhances the uptake of N, P and K. Application of N, P and K together significantly increases the growth attributes and yield of soybean. Split application of nutrients is reported to be beneficial especially when the soils are coarse textured or alkaline and calcareous in nature. Foliar application of fertilizers offers considerable scope not only for better utilization of nutrients but also for economy in fertilizer application. Higher sustained soybean yields can be obtained with judicious and balanced N, P and K fertilization combined with organic amendments.
