A review of nitrogen management strategies and their implications on maize (Zea mays L.) performance

Abstract

Maize (Zea mays L.) is one of the most versatile crops grown throughout the tropical as well as temperate regions of the world. These days, high external inputs required for high-yield goals largely depend on artificial sources and methods, among which nitrogen (N) is a source of worry worldwide. Crops need N for active growth and photosynthetic activity throughout the entire growth cycle. In Indian soils, N deficiency is a widespread problem, and correct management is crucial from an economic and environmental standpoint. Effective use depends on timing, technique, and optimal N application that is in tune with crop needs. Since maize has the largest yield potential of all the grains, it drastically depletes soils of N and water. Among other methods, maize’s response to high N fertilisation levels is a way to determine maximal productivity. Not only is crop productivity affected by N supply, but also crop quality. Employing inorganic fertiliser can boost crop output, but protecting the environment for future generations is burdensome, especially given the ongoing rise in the global population. It is possible to achieve sustainable agricultural yield by using fertilisers, both organic and inorganic, strategically.
