Abstract

An experiment was conducted at the Institute of Agriculture and Animal Sciences, Rampur, Chitwan, Nepal during the summer season of 2003 to evaluate the response of Arun 2 variety of maize to different levels of nitrogen under field conditions. The experiment was conducted using Randomised Complete Block Design (RCBD) with three replications. Results showed a highly significant difference among treatments with respect to yield. Application of 90 kg N per ha gave the highest grain yield (5.46 ton/ha) and 150 kg/ ha gave the lowest yield (4.91t/ha). But the non-significant results were found with respect to plant height, cob height, days to 50 % silking, days to maturity and number of plants per plot among treatments. The mean values for number of plants per plot, plant height, cob height, days to 50 % silking after sowing, days to maturity after sowing and yield /ha were found 21.3, 192.3 cm, 94.3 cm, 50.3, 87.5 and 5.18, respectively, Strong correlation of 0.81 and 1 were found between the traits plant height and cob height and days to 50 % silking and days to maturity respectively. In contrast, negative correlation was found between the traits plant height and yield, and cob height and yield. Key words: Nitrogenous fertiliser, yield component, maize J. Inst. Agric. Anim.
