Abstract
A field experiment was laid out in Randomized Complete Block
Design (RCBD) with three replications to study the efficacy of weed
management practices in organic finger millet during /chan/2012 at Main
Research Station, University of Agricultural Sciences, Hebbal, Bengaluru,
Among the treatments tried to manage weeds, hand weeding twice
produced the highest grain yield (5460 kg ha'1) and was on par with stale
seedbed combined with inter cultivation twice (5365 kg ha'1) as a result
of weed control efficiency (93.2 % and 91.6 %, respectively). Nutrient
uptake by finger millet was higher in hand weeding twice (95.3 N, 16.2 P
and 68.2 K kgha"1) followed by stale seedbed technique combined with
inter cultivation twice (93.7, 15.3 and 66.5, kg ha'1 respectively).
Unweeded check resulted in yield reduction of 50% due to the lowest
uptake of the nutrient by finger millet was in unweeded control
treatment (56.4 N, 4.8 P and 40.1 K kg ha'^.The stale seedbed technique
with inter cultivation twice at 20 and 35 DAP followed by hand weeding
twice at 20 and 30 DAP recorded the highest net return and B:C ratio
(Rs. 56,939 and 56,545 ha_1and 2.61, and 2.56, respectively).
