摘要
In present study, the predictive performance of WOFOST model for wheat crop has been investigated and tested by comparing the model generated output with the field observed output recorded for three consecutive crop seasons (2004-05, 2005-06 and 2006-07) at Hisar. The wheat grain and straw yield simulated by model had deviations of around 11 and 33 per cent, respectively. On an average the model overestimated grain yield by 57 kg ha(-1) and underestimated straw yield by 771 kg ha(-1). The predicted values of the maximum LAI attained by crop was quite close to the observed ones and the deviation was within 4.5 per cent
