Plant growth-promoting microorganisms can enhance sulfur uptake and boost crop production. This study was conducted to evaluate the changes in physiology, metabolism, and yield of chickpeas following the application of sulfur and two microbial consortia: (1) Thiobacillus sp., Bacillus subtilis, Paraburkholderia fungorum, and Paenibacillus sp.; and (2) Enterobacter sp. and Pseudomonas sp. The soil amendment involving a combination of sulfur and sulfur-oxidizing bacteria (SOB) in any quantity had positive effects on the availability of phosphorus, nitrogen, and potassium in the soil. A combination of 90% sulfur with Enterobacter sp. and Pseudomonas sp. resulted in a decrease in soil pH after harvesting in both years. Both years showed a strong correlation between soil pH and soil macronutrient concentration. In both years, the maximum grain yield was achieved through a combination of increased sulfur levels and SOB. The results reveal that sulfur application and SOB can increase nutrient availability, nutrient uptake, and yield of chickpea growth in calcareous soils.
促进植物生长的微生物可以提高硫的吸收并增加作物产量。本研究旨在评估施用硫和两种微生物组合后鹰嘴豆在生理、代谢和产量方面的变化：（1）硫杆菌属、枯草芽孢杆菌、真菌类伯克霍尔德菌属和类芽孢杆菌属；（2）肠杆菌属和假单胞菌属。土壤改良措施中，硫和任何数量的硫氧化细菌（SOB）组合对土壤中磷、氮和钾的有效性都有积极影响。90%的硫与肠杆菌属和假单胞菌属组合在两年收获后均导致土壤pH值下降。两年的数据均显示土壤pH值与土壤大量养分浓度之间存在强相关性。在这两年中，通过提高硫水平和SOB的组合实现了最大籽粒产量。结果表明，施用硫和SOB可以提高石灰性土壤中鹰嘴豆生长的养分有效性、养分吸收和产量。
