Abstract

This experiment was conducted in Tonekabon Rice Research Station to study the effects of different levels of nitrogen and planting densities on rice (Oryza sativa L.), cv. Promissing No.3. The experiment design was split plot (RCBD) with three replications. The treatments in main plots were in three levels (200, 250, 300 kg UREA. ha-1) and the treatments in sub plots were in four levels of planting densities (25×25, 20×20, 30×15, 30×11 cm). The recorded characteristics were YIELD, number of palmate, length of cluster, number of full plenty seeds, weight of 1000 seeds, and total above ground biomass and harvest index. The statistical analysis had shown that the effects of nitrogen levels on all characteristics were not significant. The planting densities effects were significant on YIELD (P<0.05), number of palmate (P<0.01) and total biomass (P<0.01). The interaction effects of nitrogen levels × planting densities were significant on YIELD (P<0.05) and number of full plenty seeds (P<0.01). The most effective palmates and total biomass were obtained by 30×11 cm densities. The mean comparisons with Duncan's method (at P<0.05), had shown that the highest number of full plenty seeds (118.2) were obtained by 20×20 cm densities and 200 kg N. ha-1 treatments. The most YIELDs (7689 kg. ha-1) were obtained by 30×15 cm densities and 300 kg N. ha-1 treatments it had no significant difference with 200 kg N. ha-1 together with 20×20 and 30×11 planting densities with 7596 and 7408 kg. ha-1 YIELD respectively. They could be applied by economical and sustainable considerations.
