Abstract: An experiment was conducted to assess the responses of different combinations of FYM, vermicompost, PSB, Azotobacter, nitrogenous sources (calcium nitrate and urea) along with Jeevamrut during 2015-2017 on full grown (20 years) apricot trees of New Castle cultivar, planted at a distance of 5 × 5 m. The experiment had fourteen treatments with three replicates. It has been found that different treatments had a sighificant effect on fruit quality parameters. Maximum fruit length, fruit firmness and fruit breadth, fruit suture, fruit weight and fruit volume was recorded with the application of 50% N (CN) + 50% N (Urea) + Azotobacter + PSB + Vermicompost and 0% N (CN) + 50% N (Urea) + Azotobacter + PSB + Vermicompost, respectively. While, maximum TSS, TSS/acid ratio, total sugars (11.45%), reducing sugars and minimum titratable acidity was recorded under 50% N (CN) + 50% N (Urea) + Azotobacter + PSB + FYM]. Also, maximum yield was recorded with application of 50% N (CN) + 50% N (Urea) + Azotobacter + PSB + Vermicompost during the present course of study.
