Abstract

To calibrate crop parameters and validation of ORYZA2000 model under potential production condition and simulation of leaf area index, biomass of plant organs and grain yield of three rice cultivars at different seedling ages, field experiments were carried out as split plot arrangement in randomized complete block design with 9 treatments and three replications in 2008 and 2009 growing seasons in Haraz Extension and Technology Development Center, Amol, Iran. Main plots were three rice cultivars including; Tarom, Fajr and Qaem1 and sub-plots consisted of rice seedling ages; 17, 24 and 33 days. Results showed that the model sufficiently simulated grain yield, biomass and leaf area index from transplanting to harvesting. In average, the normalized RMSE in growing period was 13-15% for TOTAL DRY WEIGHT, 18-21% for green leaf dry weight, 17-20% for stem dry weight, 16-23% for PANICLE DRY WEIGHT, 6-9% for grain yield and 24-26% for leaf area index. ORYZA2000 model had the capability to simulate growth, development and grain yield of rice cultivars and can be used as an appropriate tool for better planning of paddy field management and also as a effective supporting tool for adaptation test of improved rice cultivars in Iran.
