Crop simulation model through DSSAT and statistical model

The present investigation entitled ¿Evaluation of crop simulation modelling through DSSAT and statistical model in the yield prediction of wheat (Triticum aestivum L.) cultivars of eastern U.P.¿ was carried out during rabi 2015-16 and rabi 2016-17 at Agromet Research Farm, N. D. University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.). The experiment consisted of Randomized Block Design (RBD) at nine treatment combinations and four replications comprised of three sowing dates viz., Ist date of sowing on Nov 15 (D1), IInd date of sowing on Nov 25 (D2) and IIIrd dates of sowing on Dec 05 (D3) and three varieties viz., PBW-343 (V1), PBW-502 (V2) and HD-2967 (V3). Wheat is a cool-season crop. Cool-weather during vegetative development and warm weather for maturity is deemed ideal for wheat. The minimum growth temperature for wheat is 3-40C, the optimum temperature is about 250C, and the maximum from about 30-320C. Warm temperature during the early growth of wheat may retard heading.
