Vinayak was carried out during January-December 2016 at Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. The experiment was laid out in Randomized Block Design with 13 treatments and 3 replications. The treatments were T1 ( 200 g N + 200 g P + 250 g K ),T2 (20 kg FYM), T3 (100 g N + 100 g P + 125 g K + 10 kg FYM), T4 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T5 (20 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T6 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T7 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g),T8 (200 g N + 200 g P + 250 g K + Azotobacter 50 g), T9 (20 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g), T10 (20 kg FYM + Azotobacter 50 g), T11 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g), T12 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g) and T13 (control).The present investigation to study the effect of organic and inorganic fertilizers on growth, yield and quality of papaya (Carica papaya L.) cv. Vinayak was carried out during January-December 2016 at Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. The experiment was laid out in Randomized Block Design with 13 treatments and 3 replications. The treatments were T1 ( 200 g N + 200 g P + 250 g K ),T2 (20 kg FYM), T3 (100 g N + 100 g P + 125 g K + 10 kg FYM), T4 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T5 (20 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T6 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g), T7 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g),T8 (200 g N + 200 g P + 250 g K + Azotobacter 50 g), T9 (20 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g), T10 (20 kg FYM + Azotobacter 50 g), T11 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g), T12 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g) and T13 (control). The treatment, T4 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g) was found to significantly increase vegetative growth parameters including plant height (306.6 cm), stem girth (44.2 cm), number of leaves produced (126.6) and yield and yield attributing characters like fruit size (length = 22.6 cm and girth = 14.6 cm) , average fruit weight (1.4 kg) fruit yield per plant (33.8 kg/plant) followed by T7 (200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g) and least was observed in control. The minimum days to first flowering (105) and harvest (277) were recorded for the same treatment. With regards to quality parameters like total sugars, reducing sugars, non reducing sugars and ascorbic acid, treatment T6 (100 g N + 100 g P + 125 g K + 10 kg FYM + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g) recorded the highest value. The observations recorded non significant were titratable acidity and TSS of the fruits. With respect to NPK content in leaf tissues, highest was recorded under T6. From the results of the present study, it can be concluded that the treatment, T4 i.e. 200 g N + 200 g P + 250 g K + Azotobacter 50 g + phosphate solubilizing bacteria 50 g + Azospirillum 50 g is the best treatment with respect to growth, yield and quality parameters in papaya.ennullThesis
