Simulating the impact of climate change on sugarcane production in Punjab

The present study was performed at three diverse agro-climatic zones of Indian Punjab. A validated DSSAT-CANEGRO model used to simulate the response different climate change scenarios on cane yield four sugarcane varieties (CoPb 91, CoJ 88, Co 118 and 238) for each zone. Results described that elevated lowered minimum temperature upto 3.0°C may alter by -17.9 18.0 per cent. Similarly, ±3.0°C altered maximum -17.6 17.5 be decreased 2.4 14.4 cent, 3.3 17.6% 0.3 to15.4 cent with 2.5 15 reduced solar radiation increase in same unit enhance 1.9 9.0 1.3 13.6 2.0 12.3 Faridkot, Gurdaspur Kapurthala, respectively. A±30 mm rainfall 9.2 % similarly, rise fall CO2 5 30 ppm able decrease 2.4- 22.6 3.5 - 27.8 regions. This confirmed cultivation Punjab CoPb 91 should preferred. However, 88 238 suffer loss 7.8 9.9
