Performance Evaluation of BINArashun-1 and Selected Garlic Cultivars Under the Agro-climatic Conditions of Mymensingh, Bangladesh

Garlic (<i>Allium sativum</i> L.) is an important global bulb crop valued for its nutritional, medicinal, and economic benefits. However, its yield in Bangladesh remains below potential. This study evaluated the performance of BINArashun-1, a newly released high-yielding variety, alongside four commonly grown cultivars (Local, Italy, China, and Patnai) under the agro-climatic conditions of Mymensingh during the Rabi season of 2023-24. A randomized complete block design with three replications was employed at BINA’s Horticulture Research Farm, Mymensingh. Key traits including plant height, number of leaves, neck and bulb diameter, number of cloves per bulb, bulb weight, cured bulb weight, weight loss, and final yield were recorded and analyzed using ANOVA. Significant differences were observed for most traits. Although plant height was statistically similar across cultivars, BINArashun-1 had the highest number of leaves. China exhibited the widest neck diameter (0.90cm) but the smallest bulb diameter, while Local and Italy showed larger bulbs. Patnai and Local had the highest number of cloves per bulb, and China the fewest. Bulb and cured bulb weights were statistically similar, though Italy showed the highest weight loss during curing. In terms of yield, China produced the highest (11.62 t/ha), followed closely by BINArashun-1 (10.60 t/ha). Despite slight yield gaps from reported potential, BINArashun-1 demonstrated strong adaptability and productivity under local conditions. Its adoption could enhance domestic garlic production and reduce dependence on costly imported seed bulbs.
