Abstract

The experimental data on soybean variety JS-335 tocalibrate and validate CSM CROPGRO were collected from theexperiment of AICRP on soybean scheme during Kharif season of2006, 2012 and 2019 under rainfed conditions on deep black soils atMain Agricultural Research Station (MARS) of the University ofAgricultural Sciences, Dharwad. The simulation study revealed thatunder rainfed conditions on clay and sandy soils under both current(1988-2018) and projected climate (2020-2050) no particular patternwas observed and found that the best date of sowing for each districtwas different. Further, when the crop was simulated under thepotential conditions (fully irrigated) under both current (1988-2018)and projected climate (2020-2050) on clay and sandy soils sowinglate i.e., on 2nd fortnight of June simulated higher soybean grainyields across 12 districts of north interior Karnataka
