Effect of integrated nutrient management on chemical properties of soil under mustard crop (Brassica juncea L.) on Alfisols of Konkan (M.S.)

Abstract

The field experiment was conducted to assess the “Effect of integrated nutrient management on chemical properties of soil under mustard (Brassica juncea L.) crop on Alfisols of Konkan (M.S.)” at Department of Agronomy, College of Agriculture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri (M.S.) during the month of December to March, 2017-18. The experiment was laid out in Randomized Block Design (RBD) comprising eleven treatment combinations replicated thrice. The different treatment combinations did not show any significant effect on soil reaction, electrical conductivity and organic carbon content of soil, While, the treatment (T3) receiving application of 100 per cent RDN through poultry manure along with seed inoculations of Azotobacter and PSB recorded the highest values of available nitrogen (278.06 kg ha-1), available phosphorus (15.57 kg ha-1), available potassium (271.79 kg ha-1) and DTPA extractable micronutrients viz. iron (51.70 mg kg-1), manganese (91.57 mg kg-1), zinc (1.39 mg kg-1), copper (7.37 mg kg-1) content of soil after harvest of mustard crop.
