摘要

西孟加拉邦卡林邦的 Uttar Banga Krishi Viswavidyalaya 在 2021 年雨季（印度旱季）进行了一项田间试验，研究两个香稻栽培品种（"Kalture "和 "Kalonunia"）在四种有机养分管理（牛粪 5 吨/公顷、蛭肥 1.5 吨/公顷、芥子饼 0.5 吨/公顷和叶霉菌 1 吨/公顷）下的反应。在播种后 63 天，'Kalonunia'表现出更高的分蘖产量（435 个/平方米）、叶面积指数（3.08）和干物质积累（452 克/平方米），而'Kalture'则表现出更高的植株（137.1 厘米）和成熟时的抗倒伏性（4.0 分）。Kalonunia "在谷物产量（3.32 吨/公顷）、不倒伏习性、蛋白质含量（7.25%）和净收入（57,043 美元/公顷）方面的表现明显优于 "Kalture"。虽然施用 1.5 吨/公顷的蛭石堆肥可获得最高的谷物产量（3.22 吨/公顷）和养分吸收量（44.6 千克氮、16.4 千克磷和 39.0 千克钾/公顷），但 0.5 吨/公顷的芥子饼也可作为一种替代方法。在西孟加拉邦的丘陵地带，芥菜饼 @ 0.5 吨/公顷的产量接近最高谷物产量（3.11 吨/公顷），蛋白质含量高（7.1%），香味中等（1.7 分），净收入最高（51,040 `/公顷），效益成本比（2.01），因此可以作为一种替代选择。

Effect of organic nutrient management on yield, quality, nutrient uptake and economics of aromatic rice (Oryza sativa) in hill zone of West Bengal

A field experiment was conducted during the rainy (kharif) season of 2021 at the Uttar Banga Krishi Viswavidyalaya, Kalimpong, West Bengal, to study the response of 2 aromatic rice cultivars (‘Kalture’ and ‘Kalonunia’) under 4 organic nutrient management (cowdung manure @ 5 t/ha, vermicompost @ 1.5 t/ha, mustardcake @ 0.5 t/ha, and leaf mould @ 1 t/ha). ‘Kalonunia’ exhibited greater tiller production (435/m2 ), leaf-area index (3.08) and dry-matter accumulation (452 g/m2 ) at 63 days after planting (DAT), and ‘Kalture’ showed taller plants (137.1 cm) and lodging susceptibility (score 4.0) at maturity. ‘Kalonunia’ performed significantly better in terms of grain yield (3.32 t/ha), non-lodging habit, protein content (7.25%) and net income (`57,043/ha) than ‘Kalture’ cultivar. Although the application of vermicompost @ 1.5 t/ha resulted in the maximum grain yield (3.22 t/ha) and nutrient uptake (44.6 kg N, 16.4 kg P and 39.0 kg K/ha), mustard-cake @ 0.5 t/ha could be an alternative option owing to near-maximum grain yield (3.11 t/ha) with high protein content (7.1%), medium aroma (score 1.7), maximum net income (`51,040/ha) and benefit: cost ratio (2.01) in hill zone of West Bengal.

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.
