Abstract

An experiment was conducted during winter (rabi) season of 2021–22 at Agricultural Research Station, Chhatabar, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be) University, Bhubaneswar, Odisha to study the effect of weed and nutrient management practices on weed dynamics, yield and economics of winter transplanted organic chia (Salvia hispanica L.). The experiment was conducted in split plot design having 6 weed and 5 nutrient management practices with three replications. Among 6 weed management practices, hoeing and weeding twice at 20 and 35 days after transplanting (DAT) recorded the minimum density and biomass of weeds with weed control efficiency of 85 and 79.4% at 40 DAT and harvest, respectively. Nerium leaf aqueous extract (NLAE) 5% + castor leaf aqueous extract (CLAE) 5% + manual weeding at 35 DAT proved equally effective in weed control. Hoeing and weeding twice with 9 t/ha FYM + green manuring + Jeevamrit gave the seed, oil and protein yield of 730, 204 and 145 kg/ha, as against 720, 205 and 136 kg/ha, respectively. Weed management by NLAE 5% + CLAE 5% + manual weeding integrated with 9 t/ha FYM + green manuring + Jeevamrit and both, being statistically at par, proved to be significantly superior to all other treatment combinations. These two treatment combinations recorded statistically similar net return and return per rupee investment, and proved significantly superior to all others.

养分和杂草管理下冬季移栽有机奇异果（Salvia hispanica L.）的杂草动态、产量和经济效益

奥迪沙邦布巴内斯瓦尔的 Siksha 'O' Anusandhan（Deemed to be）大学农业科学研究所 Chhatabar 农业研究站在 2021-22 年冬季（蕾比）进行了一项试验，研究杂草和养分管理方法对冬季移栽有机奇异果（Salvia hispanica L.）的杂草动态、产量和经济效益的影响。试验采用分小区设计，有 6 种杂草管理方法和 5 种养分管理方法，三次重复。在 6 种杂草管理方法中，移栽后 20 天和 35 天锄草和除草两次的杂草密度和生物量最小，在 40 天和收获时的杂草控制效率分别为 85% 和 79.4%。事实证明，在移栽后 35 天，5% Nerium 叶水提取物（NLAE）+ 5%蓖麻叶水提取物（CLAE）+人工除草对控制杂草同样有效。用 9 吨/公顷的堆肥+绿肥+Jeevamrit 进行两次锄草和除草，种子、油和蛋白质产量分别为 730、204 和 145 公斤/公顷，而人工除草的产量分别为 720、205 和 136 公斤/公顷。采用 5%的 NLAE + 5%的 CLAE + 人工除草与 9 吨/公顷的 FYM + 绿肥 + Jeevamrit 进行杂草管理，两者在统计学上相同，证明明显优于所有其他处理组合。这两种处理组合的净收益和每卢比投资收益在统计上相似，且明显优于所有其他处理组合。

期刊介绍： Indian Journal of Agronomy welcomes concise articles presenting original research data based on field experiments on all aspects of agronomy in different crops and related cropping systems. • The journal publishes only full length comprehensive articles based on new approaches/findings in English only. • Review articles are also considered but these are normally solicited by Editorial Board. However, the authors who wish to contribute a review on their own based on their standing in the relevant field may contact the Secretary or Chief Editor with a broad outline before submitting the manuscript.
