Spinach (Spinacia oleracea L.) is an important leafy vegetable that is heavily infested with weeds. Two studies were conducted to assess the organic and inorganic mulches for control of field bindweed and purple nutsedge, and weed control in spinach. In the first study, the efficacy of mulches was evaluated to control field bindweed and purple nutsedge during spring and summer seasons. Mulches tested were: thick and thin black plastic, craft paper, card-board, woodchip and wheat straw mulches. A second experiment was conducted for non-chemical weed control in spinach. Treatments included: two controls i.e., non-treated (no mulch; weedy-check) and weed-free, and three mulches, i.e., thin plastic, craft paper, and wheat straw. All mulches provided effective (>90%) control of field bindweed except the wheat straw that had suppressed the weeds by 76.2%. Weed height, seedling fresh weight, and seedling dry weight of field bindweed were also suppressed significantly by all the mulches. Thick black plastic completely suppressed the purple nutsedge while rest of the mulches provided a >90% control of the weed except wheat straw that suppressed it by 57.8%. Weed-free treatment had the highest spinach crop cover (65.0%) while weedy treatment (no weed control) had the lowest crop cover (30.0%). The highest weed control in spinach was provided by thin black plastic mulch (90.0%) followed by craft paper mulch (83.0%) while wheat straw mulch was least effective with a 49.0% control of weeds. In conclusion, both inorganic and organic mulches were effective for weed control in spinach and suppressing the two troublesome weeds i.e., field bindweed and purple nutsedge. Nevertheless, the wheat straw mulch had the lowest weed control efficacy in both the studies. © 2020 Friends Science Publishers.en10.17957/IJAB/15.1394info:eu-repo/semantics/closedAccessCrop losses; Field bindweed; Non-chemical control; Noxious weeds; Purple nutsedge; SpinachArticle23611141120Q3
