INTEGRATED WEED MANAGEMENT IN BHINDI (ABELMOSCHUS ESCULENTUS)
An experiment was undertaken at the Farming Systems Research Station, Kottarakkara, Kerala to assess the influence of different weed management practices on the yield and economics of bhindi. The treatments included stale seed bed practice (T1), pre-emergent application of fluchloralin @ 0.4 kg a.i./ha (T2), mulching with the leaves of Mecaranta indica (vatta) (T3), paired row planting of bhindi with cowpea intercrop (T4), normal planting of bhindi with cowpea (T5), farmers practice (three to four inter cultivations with spade) (T6) and control-no weeding (T7). One inter cultivation and weeding was given to all plots uniformly at 15 DAS and T3 was applied on the same day. The results on fruit yield of bhindi indicated that the different weed management practices significantly improved the fruit yield of bhindi over control. Among the management practices, the farmers practice registered the highest yield which was on par with stale seed bed practice, pre-emergent application of fluchloralin and mulching. The intercropped plots registered comparatively lower bhindi yield but it was compensated by the intercrop yield as evident from the B:C ratio. The B:C ratio of bhindi with cowpea intercrop (T5) was the highest and was closely followed by T4, T3, T2 and T1. From the present study it could be inferred that stale seed bed practice, pre-emergent application of fluchloralin or mulching with M. indica are effective in suppressing the weeds and improving yield and economics of bhindi crop. Moreover, these practices were more economic than the farmers practice of inter cultivation and weeding with spade.
