Effect of IPNMs in Quality of Mandarin Orange

The research experiment identified the appropriate dose of Nitrogen, Phosphorous, Potassium and micronutrients (Copper, Zinc, magnesium, Iron and Manganese) to mandarin orange in order to minimize the antagonistic effect resulting from hidden deficiencies and nutrient imbalance. The study based on balance use of fertilizers (Integrated plant nutrient management system) to improves the soil structure, the quality of fruits (size, color, weight, TSS, sugar, acidity) and finally to increase the yield. The experimentation research used locally available nutrients, materials and methods which are socially acceptable, economically viable and ecologically sound.
