Abstract:
An experiment was conducted at Horticulture Experimental Farm, Department of Horticulture, College of Agriculture, Assam Agricultural University, Jorhat, Assam during the year 2020-21 and 2021-22 to find out the optimum sowing dates and varieties of onion suitable for late kharif season in this region. The treatments consisted of three dates of sowing [25^th August (D₁), 5^th September (D₂) and 15^th September (D₃)] and five varieties [Arka Kalyan (V₁), Bhima Dark Red (V₂), Agrifound Dark Red (V₃), Bhima Super (V₄) and Bhima Red (V₅)]. The experiment was laid out in factorial randomized block design with three replications. The results revealed from pooled analysis that relationship of different growth characters with various sowing dates and varieties that the minimum days to bulb development (48.52) and minimum days for bulb maturity (109.36) were recorded in D₃V₂ (Bhima Dark Red sowing on 15^th September) but Minimum bolting (2.08) and minimum number of bulb doubles (0.35) were found in D₁V₄ (Bhima Super sowing on 5^th August).
