Evaluation of some growth indices on vegetative and reproductive stage of rice cultivars under nitrogen fertilizer management
Abstract
In order to study the effects of nitrogen fertilizer on some growth indices of rice cultivars (Oryza sativa L.), an experiment as factorial in RCBD with three replications was conducted during 2009 year in the Rice Research Institute, Iran, Rasht, central of Guilan and Rudsar, East of Guilan. Factors were cultivar (V1= Hashemi, V2= Ali Kazemi and V3= Khazar), and nitrogen fertilizer levels (N1= 0, N2= 30, N3=60, and N4= 90 Kg N/ha). Characters measured were: leaf area index (LAI), leaf dry weight (LDW), Total of dry weight (TDW), Crop growth rate (CGR), net assimilation rate (NAR) and grain yield. Growth parameters were calculated during two growth stages tillering and flowering by harvesting samples in all treatments. Results of growth analysis indicated that, nitrogen increasing rates of fertilizer caused the increment of growth indexes in comparison with don’t application fertilizer, highest these growth indexes were obtained in N4 treatment. Among of rice cultivars, Khazar showed higher growth indices rather than Ali Kazemi and Hashemi.
