Effect of nitrogen levels on growth parameters, yield parameters, yield, quality and economics of maize: A review

Abstract

Nitrogen plays a prominent role in deciding the overall physiological process and biochemical reactions contributing to higher productivity and quality of maize which is a high nutrient exhaustive crop. Optimal dose of nitrogen application is necessary to obtain maximum yield and higher net returns from maize cultivation. The findings of different research scientists and eminent investigators with regard to growth parameters, yield parameters, yield and quality of maize will aid in understanding effect of nitrogen levels on growth parameters, yield parameters, yield, quality and economics of maize. Application of nitrogen at 150 to 200 kg ha-1 is found to be significant in improving the growth, yield (grain yield, Stover yield) and quality (protein content, crude protein and fibre) of maize with maximum net returns for maize cultivators.
