Abstract
Crop yield forecasting is quite important to monitor the economy of any country which is predominantly agricultural. Crop-weather Hodles are formulations which mathematically relate the crop yield with the agrometeorological parameters like evapotranspiration or crop transpiration (Tc). Very little information is available on the performance of available crop-weather models under the Indian conditions. With this background, a study was planned and conducted to test and validate the performance of different crop-weather models, during the rabi season of the years 1981-82, 1982-83 and 1983-84 with Sonalika (HDM-1553) variety of wheat. The evapotranspiration (ET) losses were measured by gravimetric soil moisture measurements which were termed actual evapotranspiration (AET) and were also estimated by Priestley-Taylor (1972) approach for obtaining potential evapotranspiration (PET).
