Influence of Integrated Nutrient Management (INM) on Biochemical Properties of Inceptisol of Surguja District of Chhattisgarh, India

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.
