Abstract

The present study was aimed at evaluating the fertility status of Kinnow orchards in aridisol order of Punjab. The soil texture of different productive Kinnow orchards was loamy sand in nature. All Kinnow orchards soils were found alkaline to saline in nature, with pH value ranging from 8.4 to 9.5 and deficient of macronutrients while sufficient in most of the micronutrients. Foliar analysis suggested that percent samples of different locations were nearly sufficient of manganese (Mn), copper (Cu), iron (Fe) and zinc (Zn) and deficient of potassium (K) and nitrogen (N). Sand and silt content significantly and positively correlated with soil pH andelectrical conductivity (EC). Soil properties showed antagonistic effect with most of soil and foliar macro-micronutrients and fruit yield. Available N showed a significant and positive correlation with soil P, K and Cu. Moreover, foliar N was positively related with foliar P and Zn, while foliar P with foliar Cu, Fe and Zn concentrations.
