Effect of split application of nitrogen on growth and yield of Kharif maize (Zea mays L.)

Abstract

In this study, N application to maize tended to improve vegetative growth. Excessive use of nitrogenous fertilizers and other chemical fertilizers affect these invaluable soil microflora and the result is barren land with less or no water holding capacity increases tissue succulency in crop plants and make them vulnerable to diseases and pests. The increased condition succulency of plant tissues helps in pests and pathogens entry and multiplication easier therefore increasing the susceptibility. Split nitrogen (N) fertilizer applications can play an important role in a nutrient management strategy that is productive, profitable and environmentally responsible. With the help of split application we can minimize the denitrification, volatilization and leaching lossess. By more specifically synchronizing nitrogen supply with a plant’s ability to utilize nutrients, split application can be an important component of 4R Nutrient Stewardship — right source, right rate, right time and right place. Split-applying nitrogen fertilizer is one way to confront these challenges. In this review, we focus on total nitrogen requirement is supplied at-planting application, most of the N must be waste.By postponing a portion of the N treatment until the crop is better able to utilize the nutrient, plants take up the nitrogen more quickly and efficiently.
