TAILIEUCHUNG - Assessment of water availability at growth stages of rainfed Kharif rice in the plains of west bengal during 2020-2099 using regional climate model output

An attempt has been made in the present paper to study the agroclimatic potential for the future periods from 2020 to 2099 with A1B-GHG ( Greenhouse Gas Emissions Scenarios) emission scenarios which have been derived from PRECIS (Providing Regional Climate for impact Studies). Rainfall data was used to estimate decadal change in the stable rainfall at various growth stages of transplanted rice of five different representative stations pertaining to Terai, Old Alluvial, New Alluvial, Red & Laterite, and Coastal Saline zones of West Bengal. Rainfall information was also utilized for determining earliest date for sowing upland crop and transplanted rice. Decadal averages of various agroclimatic indices were tested through Analysis of variance (ANOVA) for discovering significant differences. Analysis showed that distribution of stable rainfall over various growth stages of rice though showed a distinct reduction with advancement of transplanting time for 29 SMW to 35 SMW, relative differences of such resources over the future decades were inconsistent. | Assessment of water availability at growth stages of rainfed Kharif rice in the plains of west bengal during 2020-2099 using regional climate model output
