EFFECT OF PHOSPHORUS AND MOLYBDENUM NUTRITION ON GROWTH YIELD AND NUTRIENT CONTENT OF SOYBEAN IN AN ACID ALFISOL OF NAGALAND

摘要

A field experiment was conducted to evaluate the effect of phosphorus and molybdenum in soybean. The application of phosphorus significantly increased the number of leaves, plant height, nodulation, plant dry weight, yield and molybedenum increased significantly the nodulation, plant dry weight and yield only. Application of phosphorus significantly increased the nitrogen and phosphorus content in stover and seed. Likewise, application of Mo increased the N content but failed to reach significant level. Maximum P content in seed and stover recorded at 1.0 kg Mo ha~(-1) which declined sharply on 1.5 kg Mo ha~(-1), whereas Mo increased K content in seed and stover. Application of 60 kg P_2O_5 ha~(-1) and 1.0 kg Mo ha~(-1) were found to be economical for better yield and quality of soybean.
