Impact of Fertilization on Some Apple Fruit Quality Characteristics
The apple fruits are characterized with size,colour,shape,but their texture with firmness,taste,aroma.The factors determining apple fruits quality are numerous-genetic factors,environmental conditions (air temperature and humidity),light intensity,growing system,used rootstocks,irrigation,fertilization,pruning etc.The nutritional regime of apple orchard is one of the major factors for the fruit production.Apply of nitrogen,phosphorus,potassium and calcium containing fertilizers on certain qualitative characteristics of apple fruits.The nitrogen fertilization is main factor to growth of the apple trees and at the same time it has great impact on fruit size,increase fruit skin colour.Mineral fertilization levels with phosphorus,calcium,potassium show the ratio between the separate aromatic compounds in the apple fruits.The application of complex fertilization of the soil and foliar fertilization improves apple fruit quality,changed the total acidity,pH and the colour of the fruits.The fruits content more glucose,sorbitol,dry matter,fruit acids.
