Abstract
A field experiment was lay out in order to evaluate the effect of plant density to yield and yield compon ents of maize (Zea mays L.) cultivars faculty of agronomy and plant breeding, Islamic Azad University, Boroujerd Branch, Boroujerd (field location: Kohdasht), Iran during the growing seasons 2011 - 2012. The experiment was a split - plot design based of RCBD w ith three replications. Treatments were four plant spacing (10, 15, 20 and 25 cm) in main plots and three early growing corn cultivars (AS31, AS54 and BIARIS) in sub plots. Results showed that, the effect of plant density, cultivar and interaction between them on cob weight, cob length, number of row per cob, biomass yield, grain yield and harvest index (HI) were significant. The effect of plant density on 1000 grain weight was significant only. The comparison of the mean values of treats showed that, AS54 cultivar in 25cm plant density treatment had the highest cob weight. Also, AS31 cultivar in 25cm plant density treatment had the highest cob length. However, BIARIS cultivar in 25cm plant density treatment had the highest number of row per cob and biomass yield and harvest index. Although maximum 1000 grain weight achieved in 20 cm plant density but, maximum was obtained in AS54 cultivar in 20cm plant density treatment. We can planting AS54 cultivar in 20cm plant spacing for obtained maximum grain yield in Kouhdasht region. Also for gave the maximum biomass for foliage purpose we can planting BIARIS cultivar in 25cm plant spacing.
