manuscript, titled” Economic returns and selection of the best weed management method in groundnut (Arachis Hypogea L.) production in arid and semiarid lands in Kenya” for consideration in journal of Cogent Food and Agriculture. This study bridges a critical knowledge gap by assessing the variations in gross margin and cost-benefit ratios associated with herbicide use for weed management in groundnut production in Kenya’s arid and semi-arid lands (ASALs).
