Effect of Organic Nutrient Management on Soil Physical and Chemical Properties in South Gujarat Condition

A field experiment was conducted to study the effect of organic nutrient on soil properties. During rabi season of 2016-17 at Organic Farm (F block), Aspee College of Horticulture and Forestry Research Station, Navsari Agricultural University, Navsari Gujarat. The experiment was laid out in a Factorial Randomizes Block Design, comprising fifteen treatment combinations. The results indicated that significantly higher organic carbon content (1.22 %), available Nitrogen (229.52 kgN/ha), phosphorus, P2O5 (106.51 kgP/ha), potassium, K2O (599.60 kgK/ha) and Zinc (0.61 mgZn/kg) were found with the treatment O1 (100 % Nadep compost) and at par with O2 whereas, treatment O2 (75 % Nadep compost) registered significantly higher DTPA-Fe (15.35 mgFe/kg) and Manganese (17.27 mgMn/kg). No significant effect of different levels of Nadep compost was observed on pH, electric conductivity (EC), copper, DTPA-Cu and soil physical properties. Application of liquid organic manure failed to generate any significant effect on soil physic-chemical properties.
