INFLUENCE OF NON CHEMICAL WEED MANAGEMENT PRACTICES ON WEED COMPOSITION AND DIVERSITY IN TRANSPLANTED ORGANIC FINGER MILLET
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 6
Abstract
A field experiment was conducted at Main Research Station, Hebbal, Bengaluru, to study the influence of non chemical weed management practices on weed composition and diversity in transplanted organic finger millet. The results of the study showed that among the different weed control treatments, stale seed bed technique + inter cultivation twice at 20 and 35 DAP has significantly reduced the total weed density and weed dry weight and it was statistically on par with hand weeding twice at 20 and 30 DAP. Higher total weed density and weed dry weight was found in unweeded check. Highest weed control efficiency was found in manual weeding (93.2 %) followed by stale seedbed combined with inter cultivation twice (91.6 %) and passing wheel hoe twice with one manual weeding (88.7 %). Grain yield was significantly higher in hand weeding twice (5460 kg/ha) followed by stale seedbed combined with inter cultivation twice (5365 kg/ha).
