Nutritional supplements for better quality Citrus

This study was conducted to check the effect of nutritional supplements to improve the yield and quality of Kinnow mandarin. The nutritional status of the leaves was improved as a result of application of various levels of nutrients in experimental plants. Different nutrients level combination increased plant height and its canopy spreading significantly. Major yield contributing factor i.e. number of fruit set/ branch and yield (kg) were maximum in plants supplied with 80 mL Humic acid + 80 mL of multinutrient spray per plant before, after flowering and in August (three installments, February, April and August) + recommended doses of NPK and FYM. Other physical parameters like fruit weight, fruit size, pulp weight, juice percentage and seed weight were improved by various nutrients combinations. Results regarding fruit chemical parameters like, TSS, acidity, ascorbic acid contents, total sugars, reducing sugars and non-reducing sugars were significantly improved in plants supplied with various levels of nutrient combinations.
