The aim of this study was to evaluate the effect of Chromolaena odorata mulch on the yield of Amaranth under the agroecological conditions of Gbado-Lite. The experimental design chosen was that of randomized complete blocks with 3 replications and each of these replications had 4 plots or 4 treatments. The treatments were as follows: T0: control plot (no amendment); T1: mulching at 18 kg per plot or 25 t/ha; T2: mulching at 36 kg per plot or 50 t/ha; T3: mulching at 54 kg per plot or 75 t/ha. The results show that with mulching, in the first trial, 6.7; 8.8; 16.5 tons per hectare were obtained; however, in the second trial, or by exploiting the residual effects, 1.8 tons per hectare were obtained; 15; 18.3; and 37.1 respectively for the control plots; plots mulched with 25 t/ha of Chromolaena odorata; with 50 t/ha of C. odorata and with 75 t/ha of C. odorata. The experiment demonstrated that mulching improves the yield of amaranth and especially its residual effects on the crop.
