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.

critical difference, CV= co-efficient of variance There was significant improvement in all of the quality characteristics of the fruit Previous works of Garhwal et al., (2014) in Kinnow mandarin, Ghosh et al., (2014) in sweet orange and Kumar et al., (2018) in mango have reported improvement in fruit quality due to incorporation of organic manures Soil and Leaf Parameters Perusal of the data showed that most of the soil and leaf parameters gave significantly relevant differences due to the effect of the application of organic manures However, it was revealed that the different treatments had no significant effect on the pH and electrical conductivity of the soil The highest available nitrogen, phosphorus, potassium, organic carbon content of the soil and total nitrogen, phosphorus and potassium content of the leaves were recorded in T10 (Vermicompost @ 5kg + Mustard Oil Cake @ 1kg) The results of the the present findings is in accordance with Ghosh et al., (2014), who reported that incorporation of vermicompost and mustard oil cake resulted in highest available N and P content of soil and leaf It is also in concordance with Makode (2015) who reported that basal application of 10 kg vermicompost per plant resulted in significant improvement of the porosity and drainage and nutrient content of soils and water conservation Vermicompost betters the porosity and drainage, nutrient content of soil and conservation of water which subsequently results in easy uptake of water as well as deposition of nutrients The application of various organic sources caused a significant increase in organic carbon content of the soils after harvest in contrast to the initial soil status The slow releasing nature of organic manures makes consistent availability of nutrients throughout the growth period Similar outcome was found by 1017 Int.J.Curr.Microbiol.App.Sci (2019) 8(9): 1009-1019 Hazarika and Aheibam (2019) in Assam lemon This may be attributed to increased microbial population and activity, stabilization of the C:N ratio, addition of organic matter into the soil through the organic manures The increased nitrogen content may be due to the increase in the population of micro-organisms that converts the inaccessible form of nitrogen to readily available form References A.O.A.C (2002) Official methods of analysis Association of Official Analytical Chemists
