Response of Garlic (Allium Sativum L.) to Intra-row Spacing at Ajiwa Irrigation Site of Katsina State -Nigeria

Abstract

Field trials were conducted during 2010 and 2011 dry seasons under irrigation at Ajiwa in Katsina State (Lat. 13⁰ 17’ N and Long. 7⁰ 05’ E) to determine the yield responses of garlic to varying intra-row spacing. The treatments consisted of four intra-row spacings (5, 10, 15 and 20cm) which were replicated three times in a randomized complete block design. Results indicated that varying intra-row spacings from 5 to 20cm increased significantly (P <0.01) all yield characters assessed in all the trials except cured bulb yield (t/ha) which decreased as a result of increasing intra-row spacing from 5 to 20cm in all the trials. Based on the results obtained, it could be concluded that for optimum bulb yield (t/ha) in garlic, the intra-row spacings of 5cm using variety Ex-Sokoto should be adopted.
