Nitrogen and Vermicompost Interaction on Soil and Leaf Nutrient Status of Kinnow Mandarin in Vertisols of Jhalawar District

ABSTRACTA field experiment entitled “nitrogen and vermicompost interaction on soil and leaf nutrient status of kinnow mandarin in vertisols of Jhalawar district” was conducted at the Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar (Rajasthan) during 2012–13 to study the effect of different levels of nitrogen and vermicompost on physico-chemical properties of soil and leaf micro and macro nutrient contents of Kinnow mandarin. The result indicated that application of T15 treatment i.e. nitrogen at 350 g/plant + vermicompost 20 kg/plant was found best with regard to improvement in soil physico-chemical properties like organic carbon content (0.44%), available nitrogen (N) (379.36 kgha−1), available phosphorus (P) (25.56 kgha−1), available potassium (393.29 kgha−1) and reduces electrical conductivity (0.34 dSm−1), soil pH (7.42) and calcium carbonate (CaCO3) content percentage (15.20) of soil.
