Studies on suitability of groundnut genotypes in summer and rainy seasons for Riverine tract of Uttar Pradesh

An experiment was laidout during summer season of 2006-07 and rainy season of 2006-07 at Regional Research Station, Mainpuri, C.S. Azad University of Agriculture and Technology, Kanpur. The experimental soil was sandy loam with poor fertility status. The seventy five genotypes of groundnut were tested. The main objective was to findout the suitable genotypes for cultivation during summer season. The secondary objective was to work out the magnitude of yield reduction between summer season and rainy season cultivated groundnut. Among the tested genotypes in summer season Co1 registered significantly highest pod yield of groundnut by 35.41 q/ha followed by ICGS 37 (25.00 q/ha), ICGS 5 (25.00 q/ha), ICGS 76 (25.00 q/ha), ICGS 11 (25.00 q/ha), GG7 (25.00 q/ha), S206 (25.00 q/ha) and Tirupati 3 (25.00 q/ha). The cultivars TG 26, M 157, NRCG 3498, PR 1 and R 9251 also produced the pod yield by 22.91 q/ha, 20.83 q/ha, 20.83 q/ha, 20.83 q/ha and 20.83 q/ha, respectively, during summer season. During rainy season the aforementioned genotypes also give better yield. All the genotypes reduced the pod yield during summer season as compared to rainy season. The magnitude of yield reduction was recorded from 1.60 per cent to 36.64 per cent.
