Ground coverage by using selected weeds and soft herbs is an eco-friendly practice to control weeds. Hence, field experiment was conducted to investigate the feasibility of leaving some weeds species and soft herbs as a live ground cover in a tea new clearing at Ury estate of the Balangoda Plantation PLC, Passara during March to May 2021. Combination of Ageratum conyzoides and Bidens pilosa and soft herbs, combination of A conyzoides, B. pilosa, Borreria spp and soft herbs, combination of A. conyzoides, B.pilosa, and Commelina benghalensis and soft herbs, combination of A. conyzoides, B. pilosa, Borreria spp, C.benghalensis and soft herbs were used as treatments and leaving all weeds was used as the 'control'. The experiment was laid out in a Randomized Complete Block Design (RCOB) with four replicates. Weed count of removed weeds and weed dry weight were measured. Slash weeding was done at 6 week and fresh and dry weight were measured. Abundance of selected weeds and soft herb was measured once a month. Pattern of growth of selective weeds was measured weekly. The tea plant growth was also measured. The lowest weed count removed was recorded in combination of Commellina benghalensis and Bidens pilosa, Ageratum conyzoides, Borreria spp and soft herbs and it was significantly (p<0.05) lower than that of control. At 8 WAT, the lowest weed dry weight was recorded in combination of A. conyzoides ti and B. pilosa, Borreria spp and soft herbs, combination of A. conyzoides, B. pilosa and .0 benghalensis and soft herbs and combination of C. benghalensis and B.pilosa, A. conyzoides, Borreria spp and soft herbs and they were comparable and also significantly lower (p<0.05) than that of other treatments. The lowest weed dry weight was recorded in combination of A. conyzoides, .B. pilosa and C. benghalensis and it was significantly (p<0.05) lower than all the other treatments. The abundance of selective weeds were increased in T1, T2, and T3 at 8 WAT. The lowest soft herb count was recorded in the control. There was no any significant improvement in tea growth between any of treatments. Thus selected weeds can be left in the field as a ground cover.
