 In: Sarhad Journal of Agriculture (Pakistan). (Jun 1994). v. 10(3) p. 313-320Summary: Prediction of relative yields and evapotranspiration (ET) of wheat (Triticum aestivum) were made under different climatic and soil conditions using the model PLANTGRO which was developed in Western USA. Field measurements of ET from several locations (Bhalwal, Faisalabad, Bhakar and Mianchannu) in Punjab were used to verify the predictions. The model generally predicted very well and showed good agreement between computed and measured ET. Computed seasonal ET for Bhalwal, Faisalabad, Bhakar and Mianchannu was 40, 36, 44 and 44 cm respectively, and was within 4 cm of measured ET. Since prediction were accurate the model was found to be a tool to aid in crop management and irrigation scheduling
