Abstract:
Accumulation of dry matter and yield of mustard seeds have been observed from a NPK field trial experiment. Addition of nitrogen significantly increased the production of dry matter at 35 days of growth. Higher the rate of nitrogen supplied, higher was the dry matter yield. No such marked effect due to phosphorus addition was recorded, Accumulation of dry matter at harvest was significatly increased mostly by either N or P alone or by their combination. In constrast, potassium in both th« stages of growth decreased the yield of dry matter. Nitrogen and phosphorus application stimulated yield of mustard seeds almost double. Potassium supply, on the contrary, reduced the yield remarkably.
