TAILIEUCHUNG - Integrated weed management in aerobic rice (Oryza sativa L.)

A field experiment was conducted in Kharif season of 2014 at, . College of Agriculture, Instructional Farm, Rewa (.) under All India Coordinated Rice Improvement Project to study- “Integrated Weed Management in Aerobic Rice (Oryza sativa L.)”. The treatments comprised ten weed control methods which were laid out in randomized block design with three replications. Among the grassy weeds, Echinochloa species (annuals), Cynodon dactylon (perennials) and Cyperus rotundus (sedges) were the most dominating weeds. | 2018 7 1 3099-3104 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 01 2018 Journal homepage http Original Research Article https Integrated Weed Management in Aerobic Rice Oryza sativa L.

College of Agriculture Instructional Farm Rewa . under All India Coordinated Rice Improvement Project to study- Integrated Weed Management in Aerobic Rice Oryza sativa L. . The treatments comprised ten weed control methods which were laid out in randomized block design with three replications. Among the grassy weeds Echinochloa species annuals Cynodon dactylon perennials and Cyperus rotundus sedges were the most dominating weeds. Among the broad-leaved weeds Digeria arvensis Anagalis arvensis Launea asplanifolia Euphorbia hirta Eclipta alba Phylanthus niruri and Celosia argentia annuals were the dominant weed species. The study reveals that weed control in aerobic rice by need based hand weeding twice treatment T9 appeared to be more effective for getting higher production. However looking to the labour problem treatment T1 Pendimethalin @ kg . ha Bispyribac sodium @ 35 ha and T5 Butachlor @ kg . ha Bispyribac sodium @ 35 ha may be the best substitute of hand weeding twice from economic point of view. Among the weed control treatments the need based hand weeding treatment T9 and application of Butachlor 50EC Bispyribac sodium 10 SC T5 resulted in significantly higher grain yield of and kg ha .
