Application of nanocompounds and plant growth promoting rhizobacteria (PGPR) plays an important role in improving plant growth and soil health. In the present study, response of two PGPR (PS2-KX650178 and PS10-KX650179) along with nanozeolite and nanochitosan was studied on Fenugreek (Trigonella foenum-graecum), on the basis of physiological and biochemical parameters of soil and plant in pot experiment for 45 days. A significant increase (1.5–2 folds) in plant height, leaf number, leaf area and fresh weight over control was observed in Fenugreek plants when treated with nanocompounds and PGPR. Combined treatment also showed the highest level of total chlorophyll (3.27 mg g⁻¹), sugar (6.14 μg mg⁻¹ dry wt), soluble leaf protein (295.37 mg g⁻¹ fresh weight) and catalase activity (23.84 U g⁻¹ tissue) in Fenugreek plants. GC–MS analysis of plant metabolites revealed the abundance of phenols which are known to improve biotic/abiotic stresses in plants. Activity of Fluorescein Diacetate hydrolase enzyme was 2.5 times higher in the combined treatment of nanozeolite with PS10 than in control. An increase of 11% in alkaline phosphatase activity was observed in the same treatment with respect to control. The results obtained from the pot experiment clearly indicate that nanocompounds along with PGPR improved the growth of plants and soil health which suggest their benefits in agriculture practices to increase crop production.

纳米化合物和植物促生长根际细菌 (PGPR) 的应用在改善植物生长和土壤健康方面发挥着重要作用。在本研究中，根据盆栽试验中土壤和植物的生理生化参数，研究了两种 PGPR（PS2-KX650178 和 PS10-KX650179）以及纳米沸石和纳米壳聚糖对葫芦巴（Trigonella foenum-graecum）的响应。 45 天。当用纳米化合物和 PGPR 处理时，在葫芦巴植物中观察到植物高度、叶数、叶面积和鲜重比对照显着增加（1.5-2 倍）。联合处理还显示出最高水平的总叶绿素（3.27 mg g ^-1）、糖（6.14 μg mg ^-1干重）、可溶性叶蛋白（295.37 mg g ^-1胡芦巴植物中的鲜重）和过氧化氢酶活性（23.84 U g ^-1组织）。植物代谢物的 GC-MS 分析揭示了已知可改善植物生物/非生物胁迫的丰富酚类物质。在纳米沸石与 PS10 的联合处理中，荧光素二乙酸酯水解酶的活性比对照高 2.5 倍。相对于对照，在相同处理中观察到碱性磷酸酶活性增加了 11%。从盆栽实验中获得的结果清楚地表明，纳米化合物与 PGPR 一起改善了植物的生长和土壤健康，这表明它们在农业实践中有益于增加作物产量。
