Effectiveness of Integrated Weed Management Practices on Dry Matter Production and Crop Nutrient Uptake in Machine Transplanted Rice
International Research Journal of Pure and Applied Chemistry,
A field experiment entitled “Weed management in machine transplanted rice” was conducted during kharif season, 2019 at Agricultural Research Institute Farm, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad to evaluate the influence of different weed management practices on growth and nutrient uptake machine transplanted rice crop. The results revealed that among different weed management treatments hand weeding at 20, 40 DAT (T8) recorded significantly higher dry matter production at harvest (14.7 t ha-1) which was at par with T4 i.e. penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT (14.3 t ha-1). Hand weeding at 20, 40 DAT had significantly increased the crop nutrient uptake at harvest (147.0: 16.9: 153.6 NPK kg ha-1), statistically at par with penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT (142.6: 16.0: 145.4 NPK kg ha-1) while lowest was recorded with weedy check (91.9: 9.9: 89.2 NPK kg ha-1).
