Abstract:

The present investigation on “Estimation of GDD (growing degree days) under different phenophase to different rice genotypes under SRI and tradition methods of cultivation” was conducted during Kharif season 2007 with 32 genotypes of rice at Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh).It is observed from the investigation that the GDD method of computing in the crop duration is better method than duration in days. The grain yield was highest in respect of genotype R-1124-91-2-73-1 (645.8 g m-2) in SRI method of cultivation which had the highest thermal use efficiency (TUE) of 0.509 g m-2odays-1. The thermal use efficiency of genotypes provides information on the ability of the genotypes performance under thermal stress conditions. Highest number of cumulative sunshine hours of genotype R-1218-509-2-452-1, IR-64 and Mahamaya were under SRI method of cultivation. Highest light use efficiency was observed in respect of genotype R-1124-91-2-73-1(1.962 g m-2 SSH-1) followed by genotype R-1217-536-1-259-1(1.638 g m-2 SSH-1) in SRI method of cultivation.
