Abstract
Maximum nutrient uptake by weeds were recorded under unweeded check (17.06 kg ha−1) followed by metamifop (@ 100 g a.i ha−1 at 3 leaf stage) as POE and pretilachlor + safener (@ 0.4 kg a.i ha−1) at 3 DAS as PE while highest nutrient uptake by crop was resulted in weed free check (82.65 kg ha−1). Among different weed management practices highest nutrients uptake were reported in bispyribac sodium (@ 25 g a.i ha−1) at 25 DAS as POE (75.22 kg ha−1) and which was at par with cyhalofop-butyl (@ 100 g a.i ha−1) + chlorimuron-ethyl + metsulfuron-methyl (@ 4 g a.i ha−1) at 15 DAS as POE, pretilachlor + safener (@ 0.4 kg a.i ha−1 at 3 DAS) + hand weeding at 40 DAS. Though weed free check and two hand weedings at 20 and 40 DAS was reported higher nutrient uptake by crop but economically not viable option for control of weeds in direct seeded rice sown through drum seeder, hence bispyribac sodium (@ 25 g a.i ha−1) at 25 DAS as POE, cyhalofop-butyl (@ 100 g a.i ha−1) + chlorimuron-ethyl + metsulfuron-methyl (@ 4 g a.i ha−1) at 15 DAS as POE, pretilachlor + safener (@ 0.4 kg a.i ha−1 at 3 DAS) + hand weeding at 40 DAS were the best cost effective nutrient saving weed management practices under wet direct seeded rice sown through drum seeder.
