Abstract

In order to study the effects of NITROGEN fertilizer rates and plant number on yield and yield components of two RICE cultivars, a field experiment was carried out in Babol city- during 2010. A split-split plot experiment on the basis of randomized complete block design with 3 replications and 3 factors including fertilizer rate (0, 57.5 and 115 kg.ha-1), plant number per hill (3, 4 and 5) as sub plot and cultivars (Fajr and shiroudi) as sub sub plot were used. Results showed the rates of NITROGEN fertilizer had significant effect on GRAIN YIELD, harvest index, FERTILE TILLERS NUMBER, PANICLE NUMBER and biological yield. Also, different levels of plant number have not significant effects except of PANICLE NUMBER, GRAIN YIELD and biological yield. With increasing NITROGEN fertilizer application, GRAIN YIELD was increased significantly compared with control treatment (without NITROGEN fertilizer application). Interaction effect between NITROGEN fertilizer rate and cultivar was significant at 1% probability levels for GRAIN YIELD and PANICLE NUMBER in which the highest yield was belong to the NITROGEN fertilizer rate of 115 kg.ha-1 and Shiroudi cultivar. Among the mentioned traits, FERTILE TILLERS NUMBER, PANICLE NUMBER and biological yield had the highest correlation with GRAIN YIELD.
