Effect of integrated nutrient application on apple productivity and soil fertility in temperate zone of Himachal Pradesh was investigated during the years 2007 and 2008. Plant growth parameters viz terminal shoot growth, plant girth, height and spread; fruit characteristics viz fruit weight, length, breadth and yield; fruit quality parameters viz fruit pressure, total soluble solids, titratable acidity and total sugar; leaf nutrient content viz nitrogen, phosphorus and potassium and soil properties viz soil pH, OC content, available nitrogen, phosphorus and potassium were significantly affected by organic manures, bio-fertilizer and inorganic fertilizers treatments during both the years of experimentation. Maximum values of plant growth parameters, fruit characteristics, yield, leaf and soil nutrient contents were recorded under T5 (IFFCO mixture + Urea + MOP + lime + FYM) treatment followed by T1 (recommended doses) treatment and minimum values were recorded under control (T6 - without fertilizers, manures and biofertilizers) treatment. Better quality fruits were also recorded in T5 treatment.
