Effect of irrigation Interval on the Yield of Garlic (Allium sativum L.) at Ajiwa Irrigation Site of Katsina State-Nigeria

Abstract

Field trials were conducted during 2010 and 2011 dry seasons under irrigation at the Ajiwa Irrigation Site in Katsina State (Lat. 13⁰ 17’ N and Long. 7⁰ 05’ E) to study the effects of irrigation intervals on the yield of garlic (Allium sativum L.). Treatments consisted of four irrigation intervals (2, 4, 6 and 8 day) laid out in a randomized complete block design (RCBD) replicated three times. The results obtained indicated that 4 – day irrigation interval had significant and positive effect on yield parameter over other treatments. Maximum yield of 4,110.2 kg/ha was recorded from the 4 day irrigation interval while, 1,835.4 kg/ha was recorded from the 8 – day irrigation interval.
