Relationship between different growing environments and rice varieties at Raipur condition

Abstract

The performance under different growing environments with rice variety was evaluation during kharif season of 2015-16 at research and institutional farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur. The treatment combinations of three sowing dates (01 June, 15 June, and 30 June) and three varieties (Swarna, Mahamaya, MTU-1010) were laid out in a randomized block design with three replication. Were found that the highest grain yield was recorded for crop sown on 30th June (49.33 q/ha), highest straw yield on 15th June (74.77q/ha) and harvest index was highest on 30th June (42.56) and similarly different varieties influenced the grain yield where highest grain yield was recorded with Swarna 60:40:40 (54.04 q/ha), highest straw yield of variety Swarna100:60:40 (73.52q/ha) and highest harvest index was noticed with Swarna 60:40:40 (42.70). The effect of interaction between dates of sowing and varieties was found non-significant at 5% level of significance.
