Enzyme activity, agronomic nitrogen use efficiency and yield of rainfed maize (Zea mays L.) as influenced by natural nitrification inhibitors

Nitrogen is a major essential yield limiting nutrient in crop production, it serves as a constituent of many plant cell components, such as amino acids and nucleic acids. Hence it is important to improve the productivity as maize is an exhaustive crop. The low productivity of maize during kharif season is attributed to a wide range of constraints including the low nitrogen use efficiency.
