Nutrient Content with Different Fertilizer Management and Influence on Yield and Fruit Quality in Apple cv. Gala

Assessing a plant’s nutritional status and fertilizer rates types that can optimize fruit quality yield are critical in intensive apple orchards. The aim of this work was to identify correlations between nutrients the different organs allow early diagnosis assess impact on optimal nutrient content leaves, as well chemical organic fertilization. Five orchards ‘Gala’ were fertilized with levels NPK over period four years. Macro micronutrients buds, flowers, 45 90–110 days after full bloom (DAFB) leaves 60 DAFB 15 before harvest (DBH) fruits determined. Boron only element for which strong correlations, 0.7 < r 0.9, observed all organ pairs. fertilization treatments did not affect concentrations other than P, Ca Mg macronutrients fruit. In one five orchards, increased by 26% double compared standard and, depended year. Fruit size more related crop load TSS firmness affected type or amount fertilizers. Replacing part materials productivity quality.
