Not AvailableAn experiment was conducted to find out most effective method of weed management in elephant foot yam. The experiment was conducted at 10 different locations at different agro climatic conditions of India including plains, hills and islands, etc. using RBD with 8 treatments and 3 replications, and conducted during 2017 and 2018. Cyperus rotundus, Cynodon dactylon and Commelina benghalensis were most predominant weeds in most of the locations. Among different treatments hand weeding thrice at 30, 60, 90 days after planting (DAP) recorded taller plants (80.85 cm) with more pseudo stem girth, canopy spread (97.07 cm), leaf area (5435.37 cm2), highest corm yield (38.00 t/ha), gross return (Rs. 632843.11) and net returns (Rs. 387252.63) and which was at par with weed control ground cover mat mulclhing and glyphosate three sprays at 30, 60 and 90 DAP. Lower weed density and biomass were recorded in treatment with weed control ground cover mat mulching, which was at par with glyphosate applied at 30, 60 and 90 DAP.Not Availabl
