The investigation 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 to evaluate the effect of organic manures on the overall character of Assam Lemon. The experiment was laid out in Randomized Block Design (RBD) with 12 treatments and 3 replications viz. 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). 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 vegetative growth parameters. Thus, application of Vermicompost (5kg/tree) + Mustard Oil Cake (1kg/tree) before flowering to get the best crop with maximum yield and quality.
