Abstract:This paper assesses the economic use of chemicals (herbicides) compared to cultural control (hand weeding) and determines which method of control is better and more profitable. Research on chemical weed control was carried out in 1992 and 1995 in cereal-legume intercropping systems in Nigeria's Guinea Savanna (Zaria) and Sudan Savanna (Maiduguri). Economic assessment of the use of herbicides in comparison with hoe-weeding and no weeding was carried out for sorghum and groundnut production in Guinea Savanna and for sorghum and cowpea production for Sudan Savanna. The paper concludes that hoe-weeding is best for groundnut and sorghum production in the Guinea Savanna while in the Sudan Savanna the use of herbicides is best for cowpea and sorghum production.
