Abstract

In order to determine the effect of planting date and nitrogen requirements on the leaf area index (LAI) and grain yield of corn hybrid (variety SC704), a field experiment was carried out in the factorial arrangement in randomized complete block design with three replications at Gorgan Agriculture University during 2010-2011 cropping season. Three sowing dates (May 14, and May 22, July 13) were assigned as a main plot and four levels of nitrogen fertilizer (0, 100, 150 and 200 kgha ) were selected as a sub plot. The results showed 1 that sowing date had significant effect on grain yield, number of kernels per row, number of kernels per ear, 1000-grain weight, biomass, harvest index and plant height to sheath. So that the highest grain yield was obtained with 11654 kgha on May 22. Nitrogen fertilizer application was significantly affected on studied traits 1
