Simulation of Maize Phenology and Grain Yield Using DSSAT Model

The field experiment was conducted at the Farm of College Agricultural Engineering and Technology, Godhra, Gujarat during year 2018-19 2019-20 to simulate phenology yield rabi maize (Zea mays L.) in sandy loam soil central Gujarat. design split plot with 36 treatment combinations 3 replications including three irrigation regimes (1.0IW/CPE, 0.8IW/CPE 0.6IW/CPE), four mulch conditions (control, paddy straw, black plastic, reflective silver plastic mulch), stages (tasselling, silking dough stage). experimental data used for calibration validation model respectively. result revealed a significant difference grain due regime, mulching growth stages. DSSAT could good (R2 = 0.989) under simulation regimes, mulching,
