EFFECT OF POULTRY MANURE ON GARLIC (Allium sativum L) PRODUCTION IN IBADAN, SOUTH WESTERN NIGERIA

Garlic cultivation in the humid region of Nigeria is not common. Efforts to grow garlic in the south western region require fertilizer application to improve the bulb quality and overall yield. However the appropriate rate of fertilizers to use is still unknown. Therefore an experiment was carried out in  Ibadan, South Western Nigeria to assess the effect of different rates of poultry manure on the yield of garlic. The treatments compared were  five (5)  poultry manure rates ( 0, 5, 10, 15, 20 t/ ha ). The experiment was arranged in Randomized Complete Block Design (RCBD) with three replications. The lowest yield was obtained from the yield of the control; all the treatments had significantly higher yields than the control. The highest yield value was recorded on plants that received poultry manure at 20 t/ha. This could be attributed to increased quantity of nutrients from this rate of poultry manure.
