Abstract

Crop modeling can be used to help understand how multiple factors interact and impact yield. The crop modeling using of SOYBEAN-CROPGRO has been used extensively to evaluate the effects of management practices and environmental conditions on SOYBEAN growth, development, yield and yield components. In order to study of GRAIN YIELD and biomass and also investigation of CROPGRO-SOYBEAN model under four different SOWING DATE and four cultivars under growth potential in Karaj (Alborz province), one experiment carry out as a randomize complete block design in split plot arrangement with four replicate in 2009-2010. Experimental factors was different planting date 19 May (S1), 29 May (S2), 9 Jun (S3), 19 Jun (S4) as main plot and four growth limited cultivars of SOYBEAN (Wiliams, L17, M7, Zan) as sub plot. According to obtained results in this experiments, variation dimension of RMSE in all of cultivars for GRAIN YIELD (GY) 134.764-820.641 kg/ha and also variation dimension Wilmot coefficient (d) obtained 0.550-0.972. Also in all of the treatments, variation dimension RMSE for TOTAL DRY WEIGHT (TDW) obtained between 356.415-1207.338 kg/ha with d variation dimension 0.895-0.989. Generally in all of the SOWING DATEs and cultivars, R2 rate in regression curve for measured counterpoint simulated data (line1: 1) for GY obtained 0.968 with equation y=1.009 x+52.58. Also R2 rate (line 1: 1) for TDW obtained 0.932 with equation y=0.624 x+267.5.
