Abstract

The SWAP MODEL was evaluated against a data set of four irrigation management. The study was laid out in RCBD with 3 replications for one popular traditional landrace Hashemi carried out in 2005 at RICE Research Institute of Iran, Rasht. The irrigation management were 11 with continuous irrigation while 12, 13 and 14 were irrigation 1, 3 and 5 days after water disappearance of pounded water. For evaluation model are compared simulated and measured leaf area index (LAI) and BIOMASS of panicles, and total aboveground BIOMASS by absolute and normalized root mean square errors (RMSE). On average, RMSE of model were 210, kg ha-1 for yield, 501-736, kg ha-1 for total BIOMASS, 148-364 kg ha-1 for panicle BIOMASS, and 0.47-0.62 cm2cm-2 for LAI. For these crop variables, normalized RMSE values were 5% for yield, 13-21% for total BIOMASS, 6-18% for panicle BIOMASS and 93-55%. for LAI. The model simulated LAI generally exceeded measured values. SWAP MODEL simulate of WATER FLOW, to calculate soil WATER FLOW, SWAP employs Richard's equation for soil water movement in the soil matrix. The root mean square error (RMSE) range of soil water content was 0.016-0.062 and normalized root mean square error was 3-6 %.
