Abstract:
Two fifty soil and leaf samples from selected mango (Mangifera indica L.) orchards were collected in twelve mandals of YSR district of Andhra Pradesh to evaluate Physical, Physico chemical and chemical properties of soils and mango leaves during 2019-20. The soil textural classes identified were sandy loam (42.8%), sandy clay loam (38%) loamy sand (12.4%),, sandy clay (4.4%) and clay loam (2.4%) of the study area The pH of soils varied from 6.72 to 8.62 Electrical conductivity of the soils ranged from 0.13 to 0.34 dS m-1 and OC varied from 0.30 to 0.72 percent. The available nitrogen, phosphorus, potassium, sulphur, Calcium and magnesium of the soils ranged from 125 to 388 kg ha-1, 5 to 70 kg ha-1, 74 to 666 kg ha-1and 5.36 to 27.76 mg kg-1 3.87- to 36.75 and 2.16 to 22.50 cmol (p+) kg-1 respectively. The values of total N, P, K were 0.98 to 1.60, 0.03-0.51, 00.35 to 1.33 per cent, respectively. The dominant soil textural class was sandy loam. The mean concentration of nitrogen (1.27%) and Phsosphorus (0.12%) and potassium (0.60%) in the leaf samples were in optimum levels. The overall fertility status of the soils of YSR district mandals in relation to mango cultivation is moderate.
