Effect of crop establishment methods and weed management practices on yield and economics of rice (Oryza sativa L.)

A field study was undertaken to evaluate the crop establishment and weed management strategies for rice at Acharya Narendra Dev University of Agriculture and Technology, Kumarganj, Faizabad during kharif season, 2017–18. Twelve treatment combinations of two planting methods viz. transplanting, and direct seeded methods and six weed control practices viz. penoxsulam, penoxsulam fb 1 HW, bispyribac sodium, bispyribac sodium fb 1 HW, weed free and weedy check were selected for the study. Results revealed that plant growth attributes, yield attributes and grain yield was significantly superior in transplanted rice over direct seeded rice. In case of weed control practices growth characters, yield attributes, grain yield of rice were recorded the highest under weed free which was at par with bispyribac sodium fb 1 HW. The highest net return (Rs.60632) and benefit: cost ratio (1.90) was recorded under transplanted rice with bispyribac sodium fb 1 HW application
