Abstract

NITROGEN is most important elements required for RICE plant and is one of the main factors to YIELD increases. In order to study the effect of NITROGEN fertilizer rates and SPLIT on RICE variety of Hashemi and determinate of most favorable rates and SPLITting of its consumption, an experiment in factorial statistical format based on randomized complete block design (RCBD) with three replication in Iran’s RICE Research Institute stead on Rasht (Guilan), in 2009 and 2010 years was conducted. Experiments factors was consist of NITROGEN rates (N1:0, N2:30, N3:60 and N4:90 kg/ha NITROGEN from urea) and four levels of NITROGEN SPLITting respectively in stages of seedling, tillering, flowering and emersion of complete panicle include, T1 (50%,50%,0 and 0), T2 )50%, 25%, 25% and 0), T3 ( 50%, 0, 25% and 25%), T4 (25%, 25%, 25% and 25%). Results showed that different rates of NITROGEN on all measured traits had a significant difference on 1% probability level. Also different levels of NITROGEN SPLITting had a significant difference at 1% probability level in all traits except harvest index and in case of harvest index was significant in 5% probability level. The highest grain YIELD was obtained by usage of 90 kg/ha NITROGEN. In the other hand among the SPLITting levels, T4 was recorded the maximum grain yied.
