Abstract Globally, India ranks second in terms of area planted under rice (Oryza sativa) and its production as well. Potential to yield is dented due to a lack of inbuilt resistance to different biotic stresses as discernible in ~1000 rice cultivars across the country. Farmers usually rely on applying pesticides that result in several environmental adversities apart from rejection of export consignments due to the presence of chemical residue in grains. Yield losses due to pests of rice in tropical Asia range 25–43%. There is a need to explore alternative integrated input-based management options for judicious use of chemicals with optimal combinations of non-chemical interventions to improve productivity and profitability of rice culture. Field trials were conducted in split-split plot design at Chinsurah, West Bengal during three consecutive rainy (kharif) seasons (2013-15) in transplanted rice. The exploratory objectives were to assess different interventions for alleviating crop biotic stresses and obtaining precise estimate of grain yield as well as economic advantages, and to devise a cost-effective recommendation on need-based integrated pest management (IPM) in transplanted rice. Green manuring with 45-day old Sesbania crop showed a significant (P

基于投入的印度移栽水稻病虫害综合治理评估

摘要 在全球范围内，印度在水稻（Oryza sativa）种植面积和产量方面排名第二。由于在全国约 1000 个水稻品种中缺乏对不同生物胁迫的内在抗性，产量潜力受到削弱。除了由于谷物中存在化学残留物而拒绝出口货物外，农民通常依赖于使用农药，这会导致一些环境逆境。亚洲热带地区水稻病虫害造成的产量损失为 25-43%。有必要探索替代的基于投入的综合管理方案，以明智地使用化学品与非化学品干预的最佳组合，以提高水稻栽培的生产力和盈利能力。田间试验在 Chinsurah 以裂区设计进行，西孟加拉邦连续三个雨季（哈里夫）（2013-15 年）的移栽水稻。探索性目标是评估不同的干预措施，以减轻作物生物胁迫，获得对粮食产量和经济优势的精确估计，并针对移栽水稻中基于需求的综合病虫害管理 (IPM) 制定具有成本效益的建议。45 天龄田菁作物的绿肥显示显着（P
