Abstract
Soil and leaf samples were collected from 11 citrus orchards of 3–20 years of age with average growth and productivity in the month of August 2008. The gross return varies from Rs 8000–70,000 per acre the statement of growers. The EC, pH and OC of surface soil samples (0–30 cm) is almost similar with non orchard soils. The available N, P and K contents of surface soil is higher than the available N, P and K contents of non orchard soil. The Nitrogen of the surface soil has low index values whereas Phosphorus had medium index value and Potassium had high index value. Micronutrients (Zn, Cu, Mn) of surface soil have high index values whereas Iron had medium index value. Citrus plants have sufficient amount of Cu, Fe and Mn. In case of Nitrogen, 90% orchards were found to be deficient. Deficiencies of Orchards were higher in case of P and K.
