Abstract
Background and aims
Nano-zinc (Zn) fertilizer is an easily adaptable and environmentally safe alternative option that can effectively improve growth, yield and biofortification of common bean. Plant growth-promoting bacteria (PGPBs) could promote plant growth and nutrients availability in sustainable manner. Therefore, this study aimed to investigate the influence of foliar nano-Zn application in association with seed co-inoculations of PGPBs on growth, yield, biofortification and Zn use efficiencies in common bean cultivation. Two field experiments were performed with seven co-inoculations of PGPBs and three foliar nano-Zn doses applied 50% at R5 and 50% at R8 stages of common bean to determine plant height, shoot dry matter, grain yield, Zn concentration and uptake in shoot and grains, Zn partitioning index, daily Zn intake and Zn use efficiencies for agronomic biofortification.
Results
The combined foliar nano-Zn application and co-inoculation of R. tropici + B. subtilis enhance grain yield, leaf chlorophyll index, total protein content, grain Zn concentration and uptake, daily Zn intake, Zn use efficiency, applied Zn recovery and Zn utilization efficiency in common beans in 2019 and 2020 cropping seasons. Foliar nano-Zn application at a dose of 1.5 kg ha−1 increased plant height, shoot dry matter, shoot Zn uptake, Zn partitioning and agro-physiological efficiency under co-inoculation with R. tropici + B. subtilis in both cropping years.
Conclusions
The treatments with foliar nano-Zn application at a dose of 1.5 ha−1 and co-inoculation with R. tropici + B. subtilis improved performance, chlorophyll index, protein content, grain yield, and Zn efficiencies that can lead to better biofortification of common bean in tropical savannah. Therefore, it is recommended that applying nano-Zn via foliar along with co-inoculation of PGPBs could be the better option for productivity and biofortification of common bean.
背景与目的纳米锌(Zn)肥料是一种适应性强、环境安全的替代肥料，可有效促进普通豆的生长、产量和生物强化。植物生长促进菌(PGPBs)能够以可持续的方式促进植物生长和养分利用。因此，本研究旨在探讨叶面施用纳米锌与种子共接种PGPBs对普通豆生长、产量、生物强化和锌利用效率的影响。通过7次共接种PGPBs和3次叶面纳米锌，分别在R5期和R8期分别施用50%和50%纳米锌，测定普通豆的株高、茎部干物质、籽粒产量、茎部和籽粒锌浓度和吸收量、锌分配指数、日锌摄入量和锌利用效率。结果纳米锌叶面复合施用与热带真菌+ B菌共接种。枯草杆菌提高了2019和2020种植季普通豆的产量、叶片叶绿素指数、总蛋白质含量、籽粒锌浓度和吸收量、日锌摄入量、锌利用效率、施锌回收率和锌利用效率。1.5 kg ha - 1的纳米锌叶面处理增加了热带霉+ B共接种的株高、地上部干物质、地上部锌吸收、锌分配和农业生理效率。枯草属在两个种植年份都有。结论叶面施用纳米锌1.5 ha - 1，与热带热带菌+ B菌共接种处理效果较好。枯草杆菌可提高普通豆的生产性能、叶绿素指数、蛋白质含量、籽粒产量和锌效率，从而促进热带稀树草原普通豆的生物强化。综上所述，叶面施用纳米锌与PGPBs共接种可能是提高普通豆产量和生物强化的较好选择。图形抽象
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
