Studies on evaluation of fertility status of soybean growing area of Latur and its adjacent tahsil

The present investigation entitled “Studies on Evaluation of Fertility Status of Soybean Growing Area of Latur and its Adjacent Tahsil” was carried out with object to know the influence of soil and leaf nutrient status on yield and quality of Soybean during 2024-2025. The collected soil and leaf samples were analyzed for different parameters using standard procedure. 20 villages were selected from four tahsils of latur district. The results obtained are summarized below. Physico-chemical properties like pH of Nilanga tahsil soil ranged from 7.3-8.5, with average value 7.7. EC of soil was ranged from 0.4-2.6 with average value 1.2. Organic Carbon of Nilanga tahsil soil ranged from 0.15-0.78 per cent with average values 0.49 per cent. Calcium Carbonate of Nilanga tahsil soil ranged from 2-8.3 per cent with average values 4.5per cent. Available Nitrogen of Nilanga tahsil soil was ranged from 175-314348 kg ha-1 with average value 239.68 kg ha-1. Available Phosphorus ranged from 2.47-26.13 kg ha-1 with average value 13.76 kg ha-1. Available Potassium ranged from 233-999.4 kg ha-1 with average value 729.97 kg ha-1. Available Sulphur ranged from 9.12-38.05 kg ha-1 with average value 20.94 kg ha-1. Ex-Ca Nilanga tahsil soil ranged from 8.1-54.8 (cmol(p+) kg-1) with average values 39.67 (cmol (p+) kg-1). Ex-Mg Nilanga tahsil soil ranged from 9.45-38 (cmol(p+) kg-1) with average value 20.05 (cmol (p+) kg-1). DTPA micronutrients (Zn, Fe, Cu and Mn) of. Nilanga tahsil soil ranged from 0.12-0.98, 1.7-9.1, 8.1-20.32 and 1.1-9.6 Mg kg-1 with average values 0.64, 5.5, 14.52 and 2.92 Mg kg-1. Total nutrients in Nilanga tahsil (N, P, K, S) ranged from 2.23-4.6, 0.11-0.47, 2.1-6.4 and 0.12-3.8 per cent with average values 3.08, 0.22, 4.89, and 2.69 per cent and (Fe and Zn) ranged from 73-506, 8.1-79.3 ppm with average values 198.2 and 45.27 ppm. With respect to nutrient index value nilanga tahsil was categorized low in Nitrogen (1.44), Phosphorus (1.36), Manganese (1.64) and Zinc (1.63) content. Medium in Iron (2.16), While High in Potassium (2.48), Sulphur (2.48), Calcium (3), Magnesium (3) and Copper (3).
