An attempt has been made in this paper to estimate the yield of wheat crop using principal component technique. Fortnightly weather parameters viz., average maximum temperature, average minimum temperature and accumulated rainfall calculated over critical growth phases of wheat crop and trend based yield were used for the model building on agroclimatic zone basis in western zone comprises districts Hisar, Bhiwani, Sirsa and Fatehbad (Haryana). Zonal yield models provided considerable improvement in district-level yield prediction by showing good agreement with Department of Agriculture (DOA) yields. The crop yield estimates on the basis of developed models may be obtained 4-5 weeks in advance of the harvest time. The percent deviations of fitted model for all districts with in western zone are lies within acceptable limits.
