Response of wheat to temperatures as simulated with CERES-wheat model in Tarai region

Abstract

The present investigation was carried out to quantify the impact of change in minimum and maximum temperatures on wheat production in Uttarakhand using CERES-wheat model. Grain and biomass yields as simulated by the CERES-wheat (cv. BPW-343) model were found to have increased significantly due to decrease minimum (Tmin) and maximum (Tmax) temperature units from 1 to 3°C and vice-versa. Generally, minimum temperature has more significant effect than maximum temperature.
