Economic analysis of chemical weed control in irrigated garlic (Allium sativum L.) in Sudan Savanna Ecology, Nigeria

An economic analysis on the use of herbicide to control weeds in garlic production in 2002/2003 and 2003/2004 dry seasons indicated a considerable reduction in the cost of weed control and labour demand with the application of herbicide. Although the hoe weeding and the herbicide gave comparable bulb yield in 2002/2003 dry season, the net return per hectare was higher with herbicide application in both seasons. Similarly, the value of labour saved through herbicides use was positive throughout and increased significantly in 2003/2004 dry season.
