摘要

摘要植物对氮素的需要量很大,在不施用氮素的情况下获得高产是一项具有挑战性的任务。珍珠粟(Pennisetum glaucum) [L.][R. Br.]在巴基斯坦广泛的土壤中种植,其平均产量低于世界上大多数谷子生产国。细菌接种与无机肥料配合施用可促进植物的生长发育和养分积累。本研究历时两年,研究了不同氮源[尿素、硝酸铵钙(CAN)、硝基磷和硝酸铵(NH4NO3)]结合内生菌(EB)和根瘤菌(RB)接种种子或不接种种子对珍珠粟生长、产量、盈利能力和籽粒品质的影响。CAN +种子接种RB可显著提高1年和2年籽粒产量(115.7%和116.4%)、生物产量(45.5%和22.6%)和经济效益(234%和128%)。同样,尿素的氮供应增加了籽粒氮、蛋白质、铁和锌的含量。同样,接种AN +种子与RB也能显著提高土壤微生物数量。综上所述,通过CAN +种子接种RB补氮可以提高珍珠粟的生产力和净经济效益。关键词:谷物蛋白固氮细菌促进植物生长的根瘤菌生产力感谢木尔坦大学土壤系土壤肥力实验室对土壤和谷物分析的帮助。披露声明作者未报告潜在的利益冲突。

Interactive effect of different inorganic nitrogen sources and bacteria inoculation on productivity, grain quality, and economic returns of pearl millet ( Pennisetum glaucum [L.] R. Br.)
ABSTRACTNitrogen (N) is required by the plants in large quantities and obtaining higher yield without its application is a challenging task. Pearl millet (Pennisetum glaucum [L.] R. Br.) is grown on a wide range of soils in Pakistan, and average yield is lower than most of the millet producing countries in the world. Growth, development, and nutrient accumulation can be improved by bacteria inoculation combined with inorganic fertilizers. This two-year study inferred the effect of different nitrogen (N) sources [urea, calcium ammonium nitrate (CAN), nitrophos and ammonium nitrate (NH4NO3)] combined with seed inoculation with endobacteria (EB) and rhizobacteria (RB) or no seed inoculation on growth, yield, profitability, and grain quality of pearl millet. The CAN + seed inoculation with RB significantly increased grain (115.7% and 116.4% during 1st and 2nd year) and biological yield (45.5% and 22.6%), and economic returns (234% and 128%). Likewise, N supply through urea increased grain N, protein, iron (Fe) and zinc (Zn) contents. In the same way, AN + seed inoculation with RB significantly improved soil microbial population. In conclusion, N supply through CAN + seed inoculation with RB could be used to improve the productivity, and net economic returns of pearl millet.KEYWORDS: Grain proteinnitrogen fixing bacteriaplant growth promoting rhizobacteria, productivity AcknowledgmentsAll the authors are highly obliged to Soil Fertility Laboratory, Department of Soil Science, Bahauddin Zakariya University, Multan in helping with soil and grain analysis.Disclosure statementNo potential conflict of interest was reported by the author(s).

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.
