Abstract

Investigations were carried out in a split plot design replicated thrice with two levels of imrigation (0.50 IW/CPE ratio and 0.75 IW/CPE ratio), three methods of irrigation (all furrow method. alternate furrow method and paired skip furrow method) and three levels of nitrogen (75, 125 and 175 kg N ha-1. The growth characters like plant height and the yield attributes like cob length, cob width, number of grains cob and hundred grain weight were significantly increased with increase in IW/CPE ratio from 0.50 to 0.75 and with each successive increment of nitrogen. All furrow method of irrigation recorded highest growth and yield characters compared to alternate and paired skip furrow method of irrigation. Significantly highest grain and stover yields were recorded under 0.75 IW/CPE ratio with all furrow method or irrigation and at application of 175 kg N ha-1.
