Abstract:
A field experiment was conducted during the post - kharif season of 2013 at Instructional Farm of U.B.K.V, Pundibari, Cooch Beahar, W.B. to study the “ Integrated weed management practices in Ricebean (Vigna umbellata) under rainfed condition’’ with the following objectives: i) to identify the efficiency of Pendimethalin & Butachlor as pre-emergence, Quizalofop-p-ethyl as post-emergence herbicide in ricebean under Terai Agro - Climatic situation (ii) to assess the performance of pre -emergence application of herbicide as compared to the standard hand weeding/ hoeing in controlling weeds of ricebean and (iii) work out the economics of various treatments for ricebean cultivation. The field experiment was carried out in Randomized block design, having eleven (11) treatments with three replications. Finally, it may be concluded that Weed free control (T10) recorded highest seed yield followed by Hand weeding twice at 20 DAS & 30DAS (T7) and Pendimethalin (Stomp- extra 38.7% E.C) as Pre-emergence @ 1.0 kg a.i/ ha combined with one hand weeding at 30 DAS (T5). Highest Net income and benefit: cost ratio was recorded under Pendimethalin (Stomp-extra 38.7% E.C) as Pre-emergence @ 1.0 kg a.i/ ha combined with one hand weeding at 30 DAS (T5) and lowest benefit: cost ratio was recorded under weedy check (T11)
