Effect of different types and levels of Organic Manures on Yield and Yield Components of Garlic (Allium sativum L) at Kadawa, Kano, Nigeria

Abstract

Effects of different types and levels of organic manures on the yield and yield components of garlic (ex- Kofa var) was investigated. Two experiments were conducted under irrigation at the Institute for Agriculture Research (I.A.R) Kadawa in the Sudan Savanna zone of Nigeria during 2007/2008 and 2008/2009 (Nov- Mar) dry seasons. The treatments consisted of five levels (0, 2.5, 5.0, 7.5 and 10.0 tons/ha) of three types of organic manures (poultry droppings (P.D), farm yard manure (FYM)
and cow dung (CD) laid out in a Randomized Complete Block Design (RCBD) with four replications. Yield parameters studied included cured bulb weight , average bulb diameter, average number of cloves/bulb, average weight of cloves and cured bulb yield (kg/ha). The results showed Significant (P=0.5) effect of all organic manures with highest yield values obtained from poultry droppings, then cow dung and farmyard manure respectively. Increasing levels of all applied manures from 0- 10 tons/ha significantly increased all yield parameters assessed. Thus for optimum yield of garlic at Kadawa, the use of 7.5-10 tons/ha of poultry dropping could be recommended.
