Evaluation of different levels of nitrogen fertilizer on maize (zea mays l.) Under balkh province climate

ABSTRACT

In order to study the effects of nitrogen levels on yield and yield components in maize, a split plot experiment based on randomized complete block design with three replications was conducted in 2019 at the Agricultural Research Farm of Agriculture Faculty, Balkh University. Treatments were arranged in a split plot design with three replicates. Nitrogen levels (0, 80, 160 and 240 kg ha-1). Results indicated that nitrogen levels had significant effects on yield and yield components in maize hybrids. The highest grain yield was obtained from the highest levels of nitrogen fertilizer. The highest number of kernel per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height were recorded at the highest levels of nitrogen fertilizer. Maximum grain yield (7.76 ton/ha) was obtained in the plots with 240 kg ha-1 amount of Nitrogen and minimum of it (5.12 ton/ha) was obtained in the plots with 0 kg nitrogen ha-1. It can be suggested that 240 kg ha-1 amount of Nitrogen should be applied.
