Study of planting date on chorophyll content index and forage yield of sweet corn hybrids as second crop in moderate regions of Kermanshah

Due to the short growing season and harvest sweet corn at the green grass One of the most suitable plants for forage production in temperate regions of the province is the second crop. This study aimed to evaluate the effect of delayed planting date, plant height, chlorophyll content index Forage yield. four varieties of sweet corn (Bysyn, Chase, Sygnt and Merritt) was split plot experiment based on randomized complete block design with four replications at the experimental farm of Agriculture and Natural Resources Research Station in Kermanshah Province, located in the West was conducted in Islamabad In Experiment 4 on culture (June 20, July 1, July 10 and 20 July) as the main factor varieties were considered as sub-plots. The results showed that the highest plant height and dry matter yield cultivation on date (June 20), respectively, but the effect of sowing date, nitrogen and chlorophyll content were not significant.Significant differences among genotypes for all the traits studied, there was a significant difference compared to other varieties of Merit with maximum height Ratvlydkrd forage yield dry. General results can be sweet corn hybrids in order to remove for yield acceptable forage crops may be delayed temperate regions of Kermanshah.
