The experiment was conducted during 2013-2014 and 2014-2015 at the Regional Agricultural Research Station, Ishwardi, Pabna, Bangladesh to find out the appropriate irrigation schedule for optimum bulb yield and subsequent effect of irrigation schedule on storability of garlic. Th e experiments consisted of four irrigation frequencies (interval of 10, 15, 20 and 25 days) that were laid out in a randomized complete block design with three replications. Th e results showed that irrigation interval significantly influenced yield and morphological characteristics (plant height, individual bulb weight/plant, number of clove/bulb, clove weight and bulb yield). Irrigation frequency of 10 days interval resulted with the highest bulb yield of 10.48 t/ha with 372 mm of seasonal water used. It was followed by 15 days interval (9.81 t/ha) where 275 mm of seasonal water was used. It was clearly shown that the bulbs lost their weight progressively after all irrigation treatments in storage conditions. Minimum weight loss was obtained at 10 and 15 days interval. From an economic point of view, farmers can take irrigation schedules of 10 or 15 days interval for maximum return where irrigation water is available. At water stress conditions garlic might be irrigated at 20 days interval but consequently bulb yield will be reduced.
