It was carried out on two years old trees at the Citrus Fruit Block, Department of Fruit Science, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh during the year 2018. The experiment was laid out in Randomized Block Design (RBD) with 12 treatments and 3 replications. The treatments applied were: T1 – Control, T2 - RDF: N:P:K (100:100:100 g/plant/year), T3 - FYM (20kg/tree), T4 - Vermicompost (10kg/tree), T5 - Neem Cake (2kg/tree), T6 - Mustard Oil Cake (2kg/tree), T7 - FYM (10 kg/tree) + Neem Cake (1kg/tree), T8 - FYM (10kg/tree) + Mustard Oil Cake (1kg/tree), T9 - Vermicompost (5kg/tree) + Neem Cake (1kg/tree), T10 - Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree), T11 - FYM (10kg/tree) + Mustard Oil Cake (1kg/tree) + Neem Cake (1kg/tree) and T12 - Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree) + Neem Cake (1kg/tree)The experiment was laid out in Randomized Block Design (RBD) with 12 treatments and 3 replications. The treatments applied were: T1 – Control, T2 - RDF: N:P:K (100:100:100 g/plant/year), T3 - FYM (20kg/tree), T4 - Vermicompost (10kg/tree), T5 - Neem Cake (2kg/tree), T6 - Mustard Oil Cake (2kg/tree), T7 - FYM (10 kg/tree) + Neem Cake (1kg/tree), T8 - FYM (10kg/tree) + Mustard Oil Cake (1kg/tree), T9 - Vermicompost (5kg/tree) + Neem Cake (1kg/tree), T10 - Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree), T11 - FYM (10kg/tree) + Mustard Oil Cake (1kg/tree) + Neem Cake (1kg/tree) and T12 - Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree) + Neem Cake (1kg/tree) Experimental findings showed that the imposition of different treatments had a significant effect on improving the growth, yield and quality of the fruits. Maximum number of fruits/plant (85.66), fruit set (30.02%) and yield/plant (9.60 kg), juice content (47.46 ml/fruit), TSS (5.78 °B), total sugar (6.19%), reducing sugar (3.62%), ascorbic acid (52.63 mg/100 g), available nitrogen (430.52kg/ha), available phosphorus (57.30kg/ha), available potassium (306.13kg/ha), organic carbon (2.62%), total nitrogen (2.35%), total phosphorus (0.16%) and total potassium (1.66%) was recorded by treatment T10 - Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree). However, non-significant effect was found in the vegetative growth characters.ennullThesis
