Abstract:
Soybean is one of the most important crops in the Northeast of China.The efficient use of crop simulation models is an effective complement to experimental research for improving soybean productivity.The objectives of this study were to evaluate the Cropping System Model CSM-CROPGRO-Soybean for its ability to simulate phenology，grain yield and biomass with different fertilizer treatments in 1993-1996 year at Hailun Agro-Ecological Experimental Station.And a soybean model database included genetic characteristics of variety，soil，weather and field managements was established for the model performance.The evaluation of the CSM-CROPGRO-Soybean showed that the model was able to simulate the phenology and grain yield and so on with different treatments accurately，with RMSE equals 0.58 and EF equals 0.92 for phenology，and RMSE equals 101.6 kg ha-1and EF equals 0.70 for soybean yield.These results are promising for farmers and decision makers，as they could have access to accurate yield forecasts prior to final harvest.However，to be able to make practical decisions for soybean productivity and quality，it is necessary to further tested and developed with long-term experimental practices.
