Performance of Varieties on the Yield and Quality of Onion (Allium cepa l.) through Set to Bulb Method

An experiment was laid out at farm of Spices Research Sub-Centre (SRSC), Bangladesh Agricultural Research Institute (BARI), Faridpur, Bangladesh during the winter season of 2021-2022. The study comprised 3 new varieties viz. BARI Piaz-4, BARI Piaz-6 and LalTeer King, while BARI Piaz-1 was used in the study as check. The trial was conducted to explore potentialities of new developed varieties for getting higher yield and quality of onion in set to bulb method. The experiment was carried out in randomized complete block design with three replications. The finding depicted that the varieties responded significantly on the parameters studied except days to maturity of bulb and disease rating. The variety BARI Piaz-4 and LalTeer King showed the best performance on the basis of incidence of bolting, split bulb, diameter of bulb, individual bulb weight and yield of onion. On the other hand, BARI Piaz-1 had the highest dry matter content and total soluble solid content against other varieties. Finally, new developed varieties such as BARI Piaz-4 and LalTeer King would be used for getting higher yield of early green onions in set to bulb method.
