Abstract

A factorial experiment was laid out to determine an effective planting density and N fertilizer rate for a HYBRID RICE cultivar, GRH1 in a randomized complete block design (RCBD) with three replications at the Rice Research Institute of Iran (RRII), Rasht. The two factors that were considered for this factorial experiment were N fertilizer with four levels and three planting densities. ANOVA revealed highly significant differences for different N fertilizer dosage levels on comparison of yield, plant height and days to 50% flowering (DFF). While for the planting density the ANOVA showed highly significant differences for DFF and only significant differences for yield and number of unfilled grain. However, the two way interaction between N level and planting density showed non significant differences for all the traits studied. Interestingly, an application of higher N fertilizer level of 175 kg N/ha did not show any significant yield advantage over the 125 kg N/ha level for this hybrid indicating the hybrid to be highly efficient in N usage. The ideal planting density of25x 25 cm was determined with an efficient N dosage level of 125 kg N/ha for this hybrid.
