Abstract

This research aimed to determine the best combination of nitrogen levels and hybrid varieties for optimal growth and yield of hybrid maize in Sundar bazar municipality, Lamjung, Nepal. The study used a two-factor factorial randomized complete block design (RCBD) with 12 treatments and three replications. The treatments consisted of two hybrid maize varieties (Rampur Hybrid-10 and CP 808) and six different levels of nitrogen doses (control, 120, 150, 180, 210, 240 kg N ha-1). The results showed that the growth and yield parameters of hybrid maize varieties increased significantly with increasing nitrogen levels. The application of nitrogen at the rate of 240 kg N ha-1 produced the highest plant height, number of leaves, leaf area index (LAI), stem diameter, thousand grain test weight, grain per cob, grain yield, biological yield, and harvest index. Even a small difference of 30 kg of nitrogen ha-1 within a treatment showed a significant effect on the growth and yield parameters of hybrid maize. The control plot had the least growth and yield parameters. The hybrid maize variety CP 808 outperformed Rampur Hybrid-10 in terms of grain yield, thousand grain test weight, cob length, grain per cob, and LAI. In conclusion, this study suggests that cultivating hybrid maize variety CP-808 with the use of nitrogen at the rate of 240 kg ha-1 is optimal for maize production in Sundar bazar, Lamjung, and mid-hills of Nepal with similar altitude and climatic conditions. This information can assist maize farmers in achieving high yields and increasing their income.
