Abstract

Drought stress is one of the primary stresses that reduce crops’ yield in some parts of the world. In this regard, to mitigate drought stress effects on plants, farmers usually apply chemical fertilizers that lead to environmental issues. This study aimed to investigate the effect of biofertilizer application containing potassium-solubilizing bacteria (Pseudomonas koreensis and Pseudomonas vancouverensis), phosphorus-solubilizing bacteria (Pseudomonas putida), and nitrogen-fixing bacteria (Pantoea agglomerans) as an environmentally friendly biofertilizer for the growth and uptake of some essential nutrients in maize and its effect on drought tolerance. To achieve this, a Completely Randomized Design with ten treatments experiment was conducted in greenhouse conditions. The findings revealed that biofertilizers have the potential to improve maize yield and physiological characteristics, particularly under drought stress. The discussion section explores the mechanisms through which biofertilizers exert their effect and discusses practical implications for agricultural practices and environmental sustainability. Overall, this study contributes valuable insights into sustainable agricultural practices and has the potential to inform decision-making processes for farmers and policymakers.

生物肥料和硫酸钾对干旱胁迫下玉米（玉米）养分吸收和生理特性的影响

在世界一些地区，干旱胁迫是导致作物减产的主要胁迫之一。在这方面，为了减轻干旱胁迫对植物的影响，农民通常施用化肥，而化肥会导致环境问题。本研究旨在探讨施用含有钾溶解细菌（韩国假单胞菌和万古假单胞菌）、磷溶解细菌（普氏假单胞菌）和固氮细菌（泛氏聚合菌）的生物肥料作为环境友好型生物肥料对玉米生长和吸收一些必需营养元素的影响及其对抗旱性的影响。为此，研究人员在温室条件下进行了完全随机设计的十个处理实验。研究结果表明，生物肥料具有提高玉米产量和生理特性的潜力，尤其是在干旱胁迫下。讨论部分探讨了生物肥料的作用机制，并讨论了生物肥料对农业实践和环境可持续性的实际影响。总之，这项研究为可持续农业实践提供了宝贵的见解，并有可能为农民和政策制定者的决策过程提供信息。

期刊介绍： Gesunde Pflanzen publiziert praxisbezogene Beiträge zum Pflanzenschutz in Landwirtschaft, Forstwirtschaft, Gartenbau und öffentlichem Grün und seinen Bezügen zum Umwelt- und Verbraucherschutz sowie zu Rechtsfragen. Das Themenspektrum reicht von der Bestimmung der Schadorganismen über Maßnahmen und Verfahren zur Minderung des Befallsrisikos bis hin zur Entwicklung und Anwendung nicht-chemischer und chemischer Bekämpfungsstrategien und -verfahren, aber auch zu Fragen der Auswirkungen des Pflanzenschutzes auf die Umwelt, die Sicherung der Ernährung sowie zu allgemeinen Fragen wie Nutzen und Risiken und zur Entwicklung neuer Technologien. Jedes Heft enthält Originalbeiträge renommierter Wissenschaftler, aktuelle Informationen von Verbänden sowie aus der Industrie, Pressemitteilungen und Personalia. Damit bietet die Zeitschrift vor allem Behörden und Anwendern im Agrarsektor und Verbraucherschutz fundierte Praxisunterstützung auf wissenschaftlichem Niveau.
