Assessment of yield variation in rice varieties under changing climate scenario under RCP 4.5 in Chhattisgarh plain zone

Abstract

Result revealed that Panicle initiation days, anthesis days and the duration of physiological maturity of MTU-1010, Rajeshwari and CG Sugandhit Bhog under RCP 4.5 scenario is projected to decrease from present condition (2021) to future scenario i.e., 2030, 2050 and 2070 under all growing environments at Raipur condition. Highest reduction in error percentage with RMSE is projected in 2070 under all three dates of sowing while lowest reduction in error percentage with RMSE is projected in 2030 under all three growing environments. In MTU-1010, Rajeshwari and CG Sugandhit Bhog projection observed highest reduction in grain yield with error percentage and RMSE in 2070 followed by 2050 and 2030 in all three growing environments (D1, D2 and D3).
