Assessment examine of the modeling ability of ORYZA2000 for rice cultivars in Guilan province (Iran)
Abstract
Various crop growth simulation models exist for rice but thorough validation and evaluation reports are scarce. We present the model ORYZA2000, which simulates the growth and development of rice under conditions of potential production and water and nitrogen limitations. In order to evaluated model, an experiment as factorial in RCBD with three replications was conducted during 2009 year in the Rice Research Institute, Iran, and Roudsar, East of Guilan. Factors were cultivar (Khazar, Ali Kazemi and Hashemi), and nitrogen fertilizer levels (0, 30, 60, and 90 Kg N/ha). Two programs DRATES and PARAM provided by ORYZA2000 are performed for the calibration using the experimental. Evaluation assimilate and measured partitioning factors to leaves, stems, storage and above ground total (FLV, FST, FSO and FAGT respectively); leaf area index (LAI); total biomass and grain yield for each cultivar with determination R2, p(t), α, β, CRM, RMSE and RMSEn. With respect to in both locations the difference between simulated and measured total biomass of the varieties was +2 to +13% and the difference between simulated and measured grain yield was +3 to +12% (Tables 2, 3, 4), it can be concluded that the model has a high capability to simulate total biomass and grain yield of the cultivars in Guilan climate condition.
