| dc.description.abstract | A field experiments was conducted during kharif season 2018 and 2019 at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology Kumarganj, Ayodhya. (UP) with a view to find out the “Effect of different planting methods and weed management practices on the performance of paddy (Oryza sativa L.)” the experiment consisted four planting methods (Transplanting, Direct seeded rice, Drum seeded rice and System of rice intensification) and four weed management practices (Bispyribac sodium 25 g a.i ha-1 at 25 DAS/T, Bispyribac sodium 25 g a.i ha-1 at 25 DAS/T + hand weeding at 40 DAS/T, Two hand weeding 20 & 40 DAS/T and Weedy check). The treatments were accommodated in Split Plot Design with three replications. The soil of the experimental field was silty loam in texture having organic carbon (0.43%), available nitrogen (198.25 kg/ha), P2O5 (19.30 kg/ha) and K2O (290.12 kg/ha) with soil pH (7.8). The two consecutive years experimental data indicated that the highest growth characters, yield attributes, grain yield (32.07 and 34.36 q/ha), harvest index (46.16 and 47.09 %), nitrogen uptake by grain (40.09 and 43.64 kg/ha)and straw (18.71 and 19.69 kg/ha) and lowest weed flora and nitrogen removal by weeds were recorded under the SRI (System of rice intensification) and found superior over rest of the planting methods. The two hand weeding at 20 and 40 DAS/T paddy recorded maximum grain yield (34.09 and 36.53 q/ha), harvest index (48.20 and 48.72 %), nitrogen uptake by grain (39.89 and 43.84 kg/ha) and straw (17.22 and 18.46 kg/ha) and lowest weed density, weed dry weight and nitrogen removal by weeds as compared to other methods of weed management practices. | en_US |
