Abstract
The composition of major nutrients, i.e. nitrogen, phosphorus and potassium (NPK), is a critical factor in banana cultivation and also influences crop yield. This study was aimed to analyze the concentrations of NPK in different banana growing locations of coastal areas of Sindh, Pakistan. A total of 15 composite soil samples at the depth of 0 - 15 and 15 - 30 cm and the same number of banana leaves were collected. The samples were analyzed for the concentration of N, P, K, Ca, Mg, Zn, Mn and Cl concentrations. Results showed that the surface and sub-surface soils of coastal areas were heavy in texture, non-saline, medium alkaline and moderately calcareous in nature. Medium to adequate in Organic Matter (OM), medium in total nitrogen, medium to optimum in available phosphorus, medium to high in exchangeable potassium and deficient in available zinc at both tested depths. The analysis of soluble anions indicated that the carbonates were absent and that chlorides were dominant as compared with bicarbonates. Nitrogen and zinc concentrations of banana leaves were below the critical level, whereas P, K, Mn and chloride ion concentration were above the critical levels. In addition, the relative percentages for K, Ca and Mg were 57.72 to 61.72, 19.05 to 21.00 and 17.70 to 20.00 respectively.
