Abstract

To evaluate the influence of organic liquid formulations on transplanted rice, a field experiment was conducted at farm of Divyayan Krishi Vigyan Kendra, Ramakrishna Mission Ashrama, Ranchi, Jharkhand, India during kharif season of 2021 using 6 treatments (Control i.e. water, Panchagavya, Sasyagavya, Amritpani, Jeevamruth and Kunapajala) in four times replicated randomised block design. Results explored that application of Kunapajala @6% at 30 and 60 days after transplanting registered maximum growth (322.5 tillers/m2,103.6 cm plant height, 24.5 leaves/plant, 1475.1 g/m2 dry matter accumulation). Further, Kunapajala spray attained 30.4%, 4.3%, 11.8%, 14.6%, 45.5%, 43.2% and 45.6% higher panicles/m2, panicle length, grains/panicle, test weight, grain yield, straw yield and biological yield of rice, respectively, over control. However, use of Jeevamruth also performed well and remained as second-best option. Kunapajala spray further provided maximum economic profitability (net return of Rs. 83,233/ha and B:C ratio of 3.17) and therefore, it can be recommended for organically kharif rice cultivation.

在恰尔肯德邦的红土和红土土壤中，移栽的哈里发水稻对有机液体制剂的反应

为了评估有机液体制剂对移栽水稻的影响，在 2021 年印度恰尔肯德邦兰契的拉马克里希纳传教会阿诗玛（Ramakrishna Mission Ashrama）Divyayan Krishi Vigyan Kendra 农场进行了一项田间试验，采用 6 种处理（对照即水、Panchagavya、Sasyagavya、Amritpani、Jeevamruth 和 Kunapajala），四次重复随机区组设计。结果表明，在移栽后 30 天和 60 天喷洒 6% 的 Kunapajala 可获得最大的生长量（322.5 个分蘖/平方米、103.6 厘米株高、24.5 片叶/株、1475.1 克/平方米干物质积累）。此外，喷洒 Kunapajala 水稻的圆锥花序/平方米、圆锥花序长度、谷粒/圆锥花序、测试重量、谷物产量、稻草产量和生物产量分别比对照高 30.4%、4.3%、11.8%、14.6%、45.5%、43.2% 和 45.6%。然而，使用 Jeevamruth 的效果也很好，仍然是第二好的选择。Kunapajala 喷雾剂还提供了最大的经济收益（净收益为 83,233 卢比/公顷，B:C 比为 3.17），因此可推荐用于有机旱稻种植。
