Abstract: A field experiment was conducted during Kharif 2011 to generate the ground truth data of maize crop at Crop Research Station Bahraich of N.D.U.A&T, Kumarganj, Faizabad (U.P.) as to assess the “Sensitivity analysis of growth and yield attributes of maize for NEPZ region of eastern U.P.†The experiment was conducted in Split Plot Design. The treatment comprised of three dates of sowing viz. 20th June (D1), 30th June (D2) and 10th July 2011 (D3) kept as main plot with three varieties viz. Seed Tech -940 (V1), ProAgro-4212 (V2) and HQPM-1 (V3) kept as sub plot. The historical field crop data of year 2009 and 2010 were used for calibration and validation in addition to field crop data of year 2011. The performance of model tested using SD and RMSE. Result reveal that DSSAT crop growth simulation model overestimated the biomass yield, grain yield and harvest index of maize crop grown in region. While model underestimated the biomass yield of maize crop. Lowest error % was recorded in timely sown crop of maize (June 20th) with Pro Agro-4212 variety (D1V2) and error % increased with delay in sowing. DSSAT crop growth simulation model in maize crop depicted the growth and yield due varying crop growth environment.
