ABSTRACT
A field experiment was conducted to study the crop-weed competition for nutrient uptake in transplanted organic finger millet during kharif season 2012 at the Main Research Station, Hebbal, Bengaluru. Among the treatments tried to manage weeds, significantly higher nutrient uptake (N, P and K) by weeds was recorded in unweeded control treatment (32.2, 14.7 and 24.6 kg/ha respectively,) but it was on par with spraying of eucalyptus leaf extract on weeds (25.8, 12.6 and 21.2 kg/ha respectively,) and cattle urine (25.5, 10.8 and 20.0 kg/ha respectively,). Whereas, hand weeding twice at 20 and 30 DAP recorded significantly lower nutrient uptake by weeds (10.8, 3.6 and 7.8 kg/ha respectively,) followed by stale seedbed technique + Inter cultivation twice at 20 and 35 DAP (11.7, 4.8 and 8.6 kg/ha respectively,). Finger millet in hand weeding twice at 20 and 30 DAP recorded significantly higher N, P and K uptake (95.3, 16.2 and 68.2 kg/ha). However, it was on par with stale seedbed technique + Inter cultivation twice at 20 and 35 DAP (93.8, 15.33 and 66.5 kg/ha). Further, manual hand weeding twice at 20 and 30 DAP produced highest grain (5460 kg/ha) and straw yield (7200 kg/ha) and was on par with stale seedbed combined with inter cultivation twice (5365 and 7533 kg/ha, respectively). Superior yield was accompanied by 1000 grain weight, fingers/ear and finger length as compared to other treatments.
