Weed competition in cotton crop: effect of hoe-weeding on biomass and yield



Weed competition in cotton crop: effect of hoe-weeding on biomass and yield



Tropicultura 18(3): 148-151



The impact of weed interference on the biomass and yield of cotton was evaluated in a hoe-weeding experiment in Benin. The most common and numerous weeds were Cyperus rotundus, Celosia trygina Synedrella nodiflora, Commelina benghalensis, Croton lobatus and Panicum maximum. In the unweeded control, the biomass was reduced by 42, 47 and 58% compared to when crops were weeded by 1, 2 and 5 times, respectively.
