Abstract
The present experiment entitled “Influence of Integrated nutrient management (INM) on biochemical properties of Inceptisol of Surguja District of Chhattisgarh, India” was conducted during 2021-22 at village Sonwahi, Dist. Surguja. experiment out in a RBD with seven treatments i.e. T1-control, T2-50% RDF, T3-100% RDF, T4-150% RDF, T5-100% RDF + 5t/ha FYM, T6-50% RDF + 5t/ha FYM, and T7-50% RDF + 1.5t/ha The pH and EC (dSm-1) of soil doesn’t show any significant effect with different INM treatments. SOC (5.69 g kg-1) nitrogen (220.36 kg ha-1) available phosphorus and available potassium (45.81 kg ha-1, 245.42 kg ha-1,) 50% RD Field experiment that INM technique significantly influenced the activity of soil enzyme viz. dehydrogenase (48.34 µg TPF 24 hr-1 g-1), urease (40.07 μg NH4+- N g-1 soil h-1), acid phosphatase (72.93 µg p-nitrophenol g-1 hr-1) and alkaline phosphatase (45.14 µg p-nitrophenol g-1 hr-1) in 100% RDF + 5t/ha FYM (T5). The maximum bacterial load (201.00 x 107 CFU g-1) and fungal load (19.20 x 104 CFU g-1) recorded under 100% RDF + 5t/ha FYM.
