Effect of Integrated Nitrogen Management on Yield, Nutrient Uptake and Economics of Maize (Zea mays L.)

摘要

Maize (Zea mays L.) is an important staple food crop in India. It has high yield potential ha~(-1) day 1 as compared to other cereals. It is imperative to enhance the productivity by adopting new technology for exploiting yield potential under balanced nutrient supply. Maize is a heavy feeder of nutrients and remove large amount of nutrients from soil. FYM not only improves the physical condition of soil but also increase) total nitrogen uptake by enhancing the soil nitrogen supply. Use of farm yardmanure (FYM) can minimize use of chemical fertilizers and maintain the yield levels. The information leading to an efficient and economic use of integrated nitrogen management is of paramount importance. Keeping these in view, the present investigation was planned.
