Abstract

A field experiment was conducted at research farm of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal, during 3 consecutive summer seasons of 2017, 2018 and 2019, to find out the influence of varietal differences and nutrient-management practices on crop productivity, soil fertility and economics in groundnut (Arachis hypogaea L.). The experiment was laid out in a split-plot design with 3 replications. Higher crop growth and yield were recorded under variety ‘TAG 24’; and 125% recommended dose of fertilizer (RDF) with Rhizobium inoculation resulted higher growth, yield attributes and yield of groundnut followed by 100% RDF + Rhizobium inoculation. The nutrient (N, P and K) availability in soil after harvesting was also higher under ‘TAG 24’ variety with 125% RDF + Rhizobium. However, interaction effect of crop variety and fertilizer treatment was found insignificant. The pooled analysis of economics revealed that, higher benefit: cost ratio (2.73) was obtained under ‘TAG 24’ in combination with 100% RDF+ Rhizobium.

品种选择和养分管理对夏花生（Arachis hypogaea）产量、土壤肥力和经济效益的影响

2017、2018和2019年连续3个夏季，在西孟加拉邦莫汉普尔的Bidhan Chandra Krishi Viswavidyalaya研究农场进行了一项田间试验，以了解花生（Arachis hypogaea L.）的品种差异和养分管理措施对作物产量、土壤肥力和经济效益的影响。试验采用 3 次重复的分小区设计。品种 "TAG 24 "的作物长势和产量较高；125% 的建议施肥量（RDF）加上根瘤菌接种，花生的长势、产量属性和产量均较高，其次是 100% 的 RDF + 根瘤菌接种。125% RDF + 根瘤菌的 "TAG 24 "品种收获后土壤中养分（氮、磷和钾）的供应量也更高。然而，作物品种和肥料处理的交互效应并不显著。综合经济分析表明，"TAG 24 "与 100%RDF+根瘤菌的组合效益成本比（2.73）较高。

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.
