Abstract

The field experiment was conduct with factorial arrangement in RBD with three replications. In this experiment observed large-scale adoption of eight maize inbred lines in single environment at Agricultural field BHU Varanasi during Kharif (Rainy) season 2015. Four sowing dates were designed as a main plot and 4 level of N (0, 60, 120 and 170 kg/ha) applied in selected sub plot. The different sowing date expressed significant effect in maize hybrid grain yield, number of kernels per row, number of kernels per ear, 1000-grain weight, biomass, harvest index and plant height to sheath. The highest grain yield of maize inbred lines were observed with June 29 ranged 10683-11843 (kg/ha) during Kharif season 2015. N application was significantly affected on different traits expect number of kernels per row and number of kernels per ear. The recorded grain yield was 10683-11843 kg/ha from 120 kg/ha N while control produced of 11653 kg/ha maize hybrid grains. Results increasing N from 120 kg/ha to 175 kg/ha decreased grain yield of maize hybrids.
