Abstract

Increased supply of nitrogen increased the growth and yield up to 200 kg nitrogen per hectare. These parameters were higher under nitrate nutrition plants as compared to ammonium nutrition plants. However, these attributes were found to be the maximum under ammonium nitrate in which both sources of nitrogen were present. Content of nitrogen, phosphorus and potassium increased in leaves and stem of wheat plant at all the nitrogen levels with sources of nitrogen. Phosphorus showed a decreasing trend under calcium nitrate compared to ammonium sulphate.
