Abstract

In order to investigate the effect of plant density and NITROGEN levels on leaf appearance rete of COM, a split plot experiment based on randomized COMplete block design with three replications was conducted in Ardabil Agriculture Research Station in 2005. Factors were: NITROGEN levels in main plots (0, 75 and 150 kg N ha-1) and plant densities in sub plots (7, 9 and 11 plants m-2) The results showed that the effect of plant density, NITROGEN levels and the interaction of the studied factors were significant on PHYLLOCHRON and leaf appearance rate. With increased NITROGEN levels, the PHYLLOCHRON was decreased but rate of leaf appearance was increased, the revers with increasing plant density, the PHYLLOCHRON was increased but rate of leaf appearance was decreased. Maximum leaf appearance rate and minimun of phyllocron was obtained at density of 7 plants m-2 with 150 Kg N ha-1. The highest vegetative growth period and yield of COM was obtained with increasing plant density and it was found maximum in density of 11 plants m-2 and 150 Kg N ha-1.Flowering coincidence period duration was decreased with increase in plant density but it wasn't effected by NITROGEN levels. Flowering coincidence period was effected by plant density x NITROGEN levels Interaction. Mean COMparison showed that maximum flowering coincidence period was obtained in density of 7 plants m-2 with application 75 Kg N ha-1. Therefore, with increasing plant density and leves NITROGEN, increased COM yield, so it was suggested that in order to increasing leaf appearance rate and grain yield was respectively applied 7 and 11 plant density with 150 kg N ha-1.
