Abstract

A field experiment was conducted during winter of 2000–2001 to find out the effect of application of N and K levels on onion bulb yield, quality of crop and the uptake of nutrients by the crop. Treatment consisted four nitrogen and potassium levels 0, 50, 100 and 150 kg ha−1. The bulb yield was significantly higher at 150 kg N ha−1 it increased to the tune of 27.40 per cent, respectively over control, however, it significantly increased with the application of potassium at 100 kg K2O with the 14.85 per cent over control. Similarly dry matter yield, protein per cent and N, P, K, S contents as well as uptake of N, P, K and S were increased significantly over control with the application of 150 kg N ha−1 but in the case of 150 kg ha−1K2O application results were found to be non significant.
