Abstract: A field experiment was conducted during October to March, 2015-16 at the Research Farm of Department of Environmental Science, School of Forestry and Environment, SHIATS, Allahabad (U.P.) on the topic entitled “Effect of sowing date on the growth and yield of different verities of potato by using DSSAT Model” in 3x3 factorial with nine treatments and are replicated thrice. The objective of this study was to determine the response of potato to different sowing dates on growth and yield parameters of potato. The treatments included three potato varieties (Red Round, Kufri Pukhraj & G4) and three sowing dates 31^st October, 10^th November and 20^th November (2015-16). Lowest error % was recorded in days taken to fresh weight, leaf area index and Tuber yield under timely (31st October) sown potato crop with Kufri Pukhraj (D1V2) and error % increased with delay in sowing, but DSSAT model better simulate for tuber yield cv. Kufri Pukhraj under timely sown i.e. 31^st October. The yield attributing characters were closely simulate to observed values under timely (31st October) sowing of potato crop, suggested that the simulated yield were well within the accepted limits, therefore the DSSAT model can be used for predicting potato yield for this region.
