Abstract

In order to study the nitrogen REMOBILIZATION of RICE genotypes under different NITROGEN FERTILIZER levels, a field experiment was carried out in the RICE research institute (Rasht/Iran) during 1999-2000. A split-plot design based on randomized complete blocks with four replicates was used. Three nitrogen levels, includes of 0, 150 and 300 kg/ha as the main plots and three RICE genotypes includes of 424,506 and 507 as the sub plots were applied. The results showed that nitrogen REMOBILIZATION had significant differences among different levels of nitrogen. Moreover the interaction between nitrogen treatment and genotype had significant effects on nitrogen REMOBILIZATION. Different part of shoot of RICE genotypes showed different responses related to REMOBILIZATION of nitrogen, and contribution of grain nitrogen from leaves was more contributed than other parts. There were negative correlations between grain YIELD and nitrogen REMOBILIZATION. While there were positive and significant correlations between grain YIELD and harvest index and days number to 50% an thesis. Also correlation coefficient between nitrogen REMOBILIZATION and biomass were negative and significant. Moreover, correlation coefficients between nitrogen REMOBILIZATION and day's number to maturity were positive and significant.
