Performance of new wheat (Triticum aestivum L.) genotype at different dates of sowing under irrigated conditions

Abstract

The present field experiment was conducted at Agricultural Research Farm of Raja Balwant Singh College, Bichpuri Agra, during Rabi season of 2023-24 to evaluate the “Effect of new wheat (Triticum aestivum L.) varieties at different dates of sowing under irrigated conditions” to fulfill the requirement of objectives of the investigation field experiment was conducted during Rabi season. The Variables involved in this study were two dates of sowing in main plots viz., D1 (10/11/2023), D2 (10/12/2023) and eight varieties in sub plots viz., V1 (HD-2967), V2 (HI-1668), V3 (HD-3386), V4 (HD-3471), V5 (DBW-222), V6 (DBW-187), V7 (DBW-386) and V8 (PBW-826). Thus, in all 16 treatment combinations were compared in “split plot design” with three replications. The soil of experimental field was sandy loam in texture with a pH 8.50. The soil was low in available nitrogen (176.28 Kg ha-1), medium in available phosphorus (26.89 P205 ha-1) and potash (273.49 kg K2O ha-1). Studies were made during the investigation viz., Growth and development (germination counts at 15 DAS and crop stand metre-1 row length, plant height (cm), dry matter accumulation (g), days to 75% spike emergence and days to maturity; yield attributes viz., crop stand count m-2, number of spike m-2, no. of grain spike-1, weight of grains spike-1 (g) and test weight (g); per hectare studies viz., Biological, grain, straw yield (q ha-1) and harvest index (%); qualitative studies viz., N, P K content (%) and uptake (kg ha-1); economics viz., Gross returns, net returns ( ha-1) and B: C ratio. Timely sowing date (10/11/2023) was found higher productivity and quality for different varieties of wheat under irrigated conditions, different wheat varieties tested, variety DBW-222 (V5) gave better results followed by DBW-386 (V7) in respect of productivity and quality and the basis of maximum net returns ( 143027, 141345 and 139135 ha-1) and B:C ratio (3.11, 3.07 and 3.02) with wheat varieties DBW-222 (V5), DBW-386 (V7) and PBW-826 (V8) respectively, sown on 10/11/2023 (Net returns 139421 ha-1 and B:C ratio, 3.03) should be recommended for the farmers of NWPZ.
