Evaluation of varieties for their suitability and enhancement of the productivity in different rice establishment methods

Abstract

A field experiment was conducted in spit plot design with three replications to evaluate high rice varieties/hybrids under different rice establishment methods at Crop Research Station, Ghaghraghat, U.P. during kharif 2015 and 2016 The soil of experimental site was sandy loam in texture with pH 7.9, organic carbon 0.74 %, available nitrogen 260.3 Kg ha-1, phosphorus 26.1 Kg ha-1 and potash 136.4 Kg ha-1. methods of crop establishment viz. Dry Direct Seeding (M1), Dibbling of sprouted seeds (M2) and Normal transplanting (M3). In Normal transplanting rice seedling were transplanted with 20x15 cm spacing with 3 to 5 seedling per hills. The sub plot treatments of experiment were popular high yielding varieties Balwan (V1), DRR Dhan-44 (V2), Shiva – 786 (V3), Arize -6444 (V4), Mahyco -5402 (V5), 27-P-63 (V6), NDR -359 (V7) and Sarjoo-52 (V8). The results obtained during the study revealed that grain yield of the different establishment methods was in the order, normal transplanting followed by Dibbling of sprouted seeds and Dry Direct Seeding. On basis of the study it can be concluded that in areas where labour is available and cheap, normal transplanting is the best method of rice crop establishment in terms of higher grain and straw yield.
