Title : Soil And Leaf Macro-Nutrients Status In Mango (Mangifera indica L.) cv. Dashehari Orchards Under Samba District Of Jammu Region

Abstract :

Based on uniformity in respect of age and tree vigor, 22 representative orchards were selected and “Dashehari” variety of mango was selected for study. Soil (0-30, 30-60 and 60-90 cm depths) and plant (leaf) samples collected from mango orchards were analyzed for physico-chemical properties (pH, EC, OC) and macro-nutrients (N, P, K, Ca, and Mg, S). The Organic carbon contents were medium to high. The per cent coefficient of variations found high in soil and plants could be due to variations in parent material and orchard management practices. Electrical conductivity was positively and significantly correlated with Potassium, Calcium and Magnesium and Organic carbon with Calcium and Magnesium. Available Phosphorus exhibited positive and significant relationship with their respective leaf nutrient contents. Soil samples were collected from three depth of soil viz., 0-30cm, 30-60 cm and 60-90 cm and analyzed for various physico- chemical properties and nutrient status. Leaf and fruit samples were also collected from the same orchards and analyzed for nutrient content, quality parameters and yield. These mango orchards have shown variation in soil pH 6.24-7.42, Electrical conductivity 0.05-0.27 ds/m, Organic carbon (0.21-1.90 %) from surface layer 0-30 cm, pH 6.30- 7.46 and 6.33-7.48, Electrical conductivity 0.04- 0.25ds/m and 0.03-0.24 ds/m and Organic carbon (0.18- 1.86 %) and (0.15-1.84%) from the sub- surface layer 30-60 cm and 60-90 cm. Nitrogen (107.10-298.26), (75.60-282.63) and (57.80-280.15) kg ha-1 from the surface and sub- surface of the soil layers. Phosphorus (7.60-22.90), (6.90-20.00) and (6.20-18.42) kg ha-1 Potassium (95.10-224.23), (90.00-217.19) and (79.34-210.00) kg ha-1 Calcium (4.02-6.35), (4.00-6.32) (4.00-6.29) [c mol (p+) kg]-1 from the soil depth 0-30, 30-60 and 60-90 cm, Magnesium (2.18-3.32), (2.16-3.28) (2.14-3.28) [c mol (p+) kg]-1 and Sulphur (12.60-19.74), (10.40-17.90) and (9.80-16.95) kg ha-1. The leaf nutrients ranged Nitrogen (1.10-2.22%), Phosphorus (0.11 -0.21%) Potassium (0.19-0.41%), Calcium (1.8-2.24 %), Magnesium (0.42-0.82 %) and Sulphur (0.04-0.25 %) respectively.
