Economics of Weed Control Methods in Transplanted Rice Fields in Mid-hill of Nepal

Abstract

To assess economic of different weed control methods on transplanted rice, a research was conducted at farmers’ fields, Bhanu-11, Rupakot, Nepal during the rainy season of 2017. The experiment was laid out using single factorial Randomized Complete Block Designs (RCBD) with three replications of ten treatments as one hand weeding at 21 Days After Transplanting (DAT) (T₁); two hand weedings at 21 and 42 DAT (T₂); three hand weedings at 21 42 & 63 DAT (T₃); single conoweeding at 21 DAT (T₄); double cono weedings at 21 &42 DAT (T₅); triple cono weedings at 21, 42 &63 DAT (T₆); butachlor as pre emergence (T₇); butachlor with single manual weeding at 21 DAT (T₈); butachlor with double manual weedings at 21 & 42 DAT (T₉) and weedy check (T₁₀). All collected data were subjected to analyzed by computer software R package. The results revealed that butachlor as pre-emergence (T₇), showed that significantly higher gross return (Rs. 167.51thousand/ha), net profit (Rs. 96.11thousand/ha) and higher benefit-cost ratio (2.346), which is economically viable and profitable and can recommend to the farmers for rainfed lowland condition.
