Field trials were carried out during 2002/03 and 2003/04 dry seasons (Nov. to March) at Sokoto to investigate the performance of garlic (Allium sativum L.) to varying levels of irrigation interval and clove size. Treatments consisted of factorial combinations of four irrigation intervals in days (3, 5, 7 and 9 days) and two clove sizes (small, < 2 cm and large, 2-3 cm). Treatments were laid out in a randomized complete block design with three replications. The results obtained revealed that 3-day irrigation interval significantly affected number of leaves per plant, plant height at maturity, bulb yield, bulb weight, number of cloves per bulb and clove weight throughout the period of investigation, while increase in the number of days between irrigation interval negatively affected the growth and yield and performance of the garlic. Generally, 3-day irrigation interval out-yielded the rest of the irrigation intervals in all the parameters assessed in both seasons. Clove size had significant effect on the number of leaves per plant, plant height, bulb yield, bulb weight, number of cloves per bulb and clove weight and they increased as the clove size increased. Large sized cloves had significantly and consistently out yielded small sized cloves in both seasons. It was concluded from this study that large clove size and applying irrigation at 3-day interval may be recommended for good performance of garlic under semi-arid condition of Sokoto, Nigeria.
