Abstract

Application of Nitrogen (N) at 150 mg kg-1 soil significantly increased the grain and straw yield of wheat from 2.70 to 8.24 and 4.97 to 9.44 g pot-1, respectively over control. Addition of vermicompost at 1% alone increased the grain and straw yield of wheat from 2.70 to 4.81 and 4.97 to 6.60 g pot-1 respectively over control and in combination with N at 150 mg kg-1 soil further improved from 4.81 to 10.73 and 6.60 to 11.89 g pot-1, respectively. Use of Clodinafop propargyl at 60 and 90 g a.i. ha-1 significantly decreased the grain yield of wheat from 4.74 to 3.60 and to 2.93 g pot-1, respectively and that of straw yield from 7.16 to 5.87 and to 4.31 g pot-1, respectively over control (without  C. propargyl). The grain and straw yield of wheat also decreased significantly with the application of C. propargyl (60 to 90 g a.i./ha) in presence of both vermicompost and N. Nitrogen, Phosphorus (P) and Potassium (K) uptake by grain and straw increased significantly with the increase in each successive dose of N up to the level of 200 mg kg-1 soil and highest uptake of NPK by grain were 149.56, 57.59 and 40.87 mg pot-1, respectively and that of by straw the highest value recorded were 54.72, 18.24 and 143.78 mg pot-1, respectively. Application of vermicompost at 1% significantly increased NPK uptake in both grain and straw over control. Use of C. propargyl at 60 and 90 g a.i. ha-1 significantly decreased the NPK uptake by grain and straw.
