Abstract

ABSTRACT Use of saline-sodic irrigation water degrades soil health and reduced mustard yield, particularly in India’s low-rainfall regions. This research was conducted to assess the effect of sodic water and nitrogen sources on soil organic carbon (SOC), microbial biomass, soil enzymatic activities, and interaction effects on mustard seed yield. The experiment was laid out in split-plot design comprising four levels of sodium adsorption ratio (SAR) of water (6, 10, 20, and 30) and six nitrogen sources [(control, 125% recommended dose of nitrogen (RDN) through urea, 75% RDN+50% RDN through farm yard manure (FYM), 75% RDN through urea+50% RDN through vermicompost (VC), 50% RDN through urea+75% RDN through FYM, 50% RDN through urea+75% RDN through VC]. The use of high SAR irrigation water caused a significant reduction in soil fertility and microbial parameters. The combined use of chemical fertilizers, FYM, and vermicompost significantly increased microbial activities (64.9% SMB-C), SOC (23.5%), soil enzyme activity (dehydrogenase and alkaline phosphates), and mustard seed yield (49%). The use of 50% RDN via urea+75% RDN via VC was suggested as a better technology for minimizing the adverse effect of high SAR water on crop yield.

苏打灌溉条件下添加有机改良剂介导的土壤肥力、微生物动态和芥菜产量潜力

摘要盐碱灌溉水的使用降低了土壤健康，降低了芥菜产量，尤其是在印度的低降雨量地区。本研究旨在评估苏打水和氮源对土壤有机碳（SOC）、微生物生物量、土壤酶活性的影响，以及相互作用对芥菜种子产量的影响。试验采用分块设计，包括四个水平的水钠吸附率（SAR）（6、10、20和30）和六个氮源[（对照组，125%推荐剂量的尿素氮（RDN），75%推荐剂量的农家肥（FYM）+50%推荐剂量，75%推荐量的尿素+50%推荐剂量的蚯蚓堆肥（VC），50%RDN通过尿素+75%RDN通过FYM，50%RDN-通过尿素+75%RDN通过VC]。使用高SAR灌溉水导致土壤肥力和微生物参数显著降低。化肥、FYM和蚯蚓堆肥的联合使用显著提高了微生物活性（64.9%的SMB-C）、SOC（23.5%）、土壤酶活性（脱氢酶和碱性磷酸盐）和芥菜种子产量（49%）。建议通过尿素使用50%RDN+通过VC使用75%RDN是一种更好的技术，可以最大限度地减少高SAR水对作物产量的不利影响。

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
