Abstract 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.

Introduction Several limiting factors like irrigation facilities, nutrient management and shortfall of extension facilities are usually related to low agricultural production in India (India Country overview 2008). Management of agricultural practices using new technologies is found to be economical and environment friendly. Application o
