Abstract
It is expected that up to 2050, human population will be doubled. Agricultural researchers are striving their best to meet the food challenges. To get the higher yield, nitrogenous fertilizers use is also being increased. Nitrogenous fertilizers play vital roles in different plant’s growth and developmental processes. But, excessive use of nitrogen is no more beneficial to plants. Only 30 to 50% nitrogen use efficiency is recorded in plants, the remaining nitrogen is used by soil microbes, leached down in soil profile or volatilized. Different agronomical practices have been practiced and suggested for the general cultivation. Proper use of these agronomical practices can increase the crop yield and nitrogen use efficiency.
