Abstract
Garlic (Allium sativum L.) is a widely consumed root vegetable mostly for its nutritional, health and economic values. In Cameroon, the production rate of garlic is below its demand primarily due to low soil fertility. A field experiment was conducted at the research plot of the Faculty of Science of the University of Bamenda, to investigate the effect of three organic manures (poultry, goat and pig manures) on the growth and yield of garlic in order to increase productivity. The experiment was laid out in a randomized complete block design with three replications and four experimental plots treated with poultry droppings, goat dung, pig dung and the control. Each experimental plot had a dimension of 2.5 m × 1 m. Manure weights of 2.5 kg of each type were applied to each of the plots. Growth and yield parameters for the different treatments were measured weekly from the second week of planting to the 16th week. Results revealed that overall, the application of organic manure improved growth and yield of garlic with significant differences (p < 0.05) among all the treatments. Poultry manure produced highest bulb yield (760.5 ± 16.99 kg/ha) while goat dung the least (625.8 ± 25.84 kg/ha). Poultry manure is therefore recommended for productive growth of garlic.
Key words: Bambili, fertility, garlic, organic manure, yield.
