Abstract

Field trials were carried out to assess (i) the optimum level of nitrogen and (ii) the time and methods of its application. Split application of N, 40 kg/ha applied in soil at planting and two foliar spraying @ 20 kg/ha after 50 to 60 days after planting proved optimum, resulting in 41–116% increase in yield over control (No application of N).

It was observed that kharif crops yielded higher than the rabi crops.
