Abstract:

The experimental data collected at Anand station (Latitude 22o 35’, Longitude 72o55’, altitude 45.1 MSL) during the year 2015 and 2016 for various irrigation levels, varieties and spacing (I1- 0.8 IW/CPE ratio, I2- 0.6 IW/CPE ratio, I3- 0.4 IW/CPE ratio, V1- Meha, V2- GM-4, S1- 45 cm row to row spacing S2- 30 cm row to row spacing). Were used to calibrate and validate the model. The quantification of the impact of projected changes in climatic parameter such as atmospheric CO2, temperature and rainfall on mungbean crop production was assessed using validated DSSAT4.6 (CROPGRO) model for Anand districts of Gujarat. The normal daily BSS data was used in the model. The DSSAT (CROPGRO) model was used to simulate the phenology and yield and yield attributes using daily data of baseline (1961-1990) and projected period (2071-2100). Possible effects of climate change on plant growth were evaluated using the crop growth simulation model. Projected CO2 concentration and temperature projections were applied as climate change study. The PRECIS outputs for the A2- scenarios (2071-2100) indicated that the mean maximum, minimum temperature and rainfall are expected to increase by 4.6 to 4.3 0C and 402 mm respectively at Anand district. Results revealed that the reduction in anthesis days may be highest (16.1%) in treatment I3V2S2 and lowest (5.7%) in treatment I1V1S1, However the duration of days to physiological maturity are projected to be reduced, in all treatments of green gram. However the reduction may be highest (23.8%) in treatment I3V2S2 and lowest (10.5%) in treatment I1V1S2. The grain yield reduction due to impact of climate change ranged 7.5 per cent to 21.3 per cent at different treatment. The highest yield reduction was projected in I3V2S2 and lowest was projected in I1V1S2, while mean yield reduction was 7.5 %.
