Response of barley (Hordeum vulgare L.) varieties to different dates of sowing under irrigated conditions

Investigation entitled “Response of barley (Hordeum vulgare L.) varieties to different date of sowing under irrigation conditions” was carried out at Agricultural Research Farm of Raja Balwant Singh College, Bichpuri Agra, during Rabi season of 2022-23. The Variables involved in this study were four dates of sowing D1 (Nov. 16th) and D2 (Dec. 10th) and four varieties of barley viz. SLS-67 (V1), BH-946 (V2), WRB-160 (V3) and DWRB-137 (V4). Thus, in all 8 treatment and combinations were compared in a split plot design having dates of sowing in main plots and varieties in sub plots with three replications. The soil of experimental field was sandy loam in texture with a pH 8.45. The soil was low in available nitrogen (181.49 Kg ha-1), medium in available phosphorus (27.86 PO, ha-1) and potash (279.37 kg K2O ha-¹). The field capacity was 18.64 per cent. During Rabi reason of 2022-23, only 9.7 mm rainfall was received. Result reveled that November (16th) sowing date was found best for different varieties of barley under irrigated conditions. Among the tested barley varieties, BH-946 exhibited superior performance concerning grain and straw yield. Based on the highest net return and B:C ratio.
