To meet the growing international demand for aromatic rice, this study, conducted at Uttar Banga Krishi Viswavidyalaya in Cooch Behar, West Bengal, aimed to enhance the yield and quality of the 'Tulaipanji' rice cultivar through advanced establishment methods and the use of organic nutrients over two years. The research tested three planting techniques: mechanical transplanting, wet direct seeding (using a drum seeder), and traditional methods, alongside four nutrient management strategies: vermicompost, farmyard manure, a mix of both, and conventional fertilizers. Findings revealed that mechanical transplanting significantly increased yield by over 31.98% and 71.05% compared to traditional methods and wet direct seeding, respectively. Using vermicompost alone as a nutrient source not only boosted yields by 21.31% over conventional fertilizers but also enhanced the rice's nutritional value and cooking quality. Moreover, soils treated with vermicompost showed higher dehydrogenase activity, indicating better soil health. Economically, mechanical transplanting with vermicompost was the most beneficial, yielding the highest net returns and benefit-cost ratios in both years studied. This approach presents a viable model for improving the sustainability of aromatic rice production globally, emphasizing the economic and environmental advantages of adopting mechanical planting techniques and organic fertilization methods.
为了满足日益增长的国际芳香稻需求,本研究在西孟加拉邦古茶拉底农业大学进行,旨在通过先进的建立方法和在两年内使用有机养分来提高‘图拉潘吉’水稻品种的产量和质量。该研究测试了三种种植技术:机械移栽、湿直播(使用鼓式播种机)和传统方法,以及四种养分管理策略:蚯蚓粪、农家肥、两者的混合物和常规肥料。研究结果表明,与传统方法和湿直播相比,机械移栽分别显著提高了 31.98%和 71.05%的产量。单独使用蚯蚓粪作为养分来源不仅使产量比常规肥料提高了 21.31%,还提高了水稻的营养价值和烹饪品质。此外,用蚯蚓粪处理的土壤显示出更高的脱氢酶活性,表明土壤健康状况更好。从经济角度来看,机械移栽配合蚯蚓粪是最有益的,在研究的两年中都产生了最高的净回报和收益成本比。这种方法为提高全球芳香稻生产的可持续性提供了可行的模式,强调了采用机械种植技术和有机施肥方法的经济和环境优势。
