Abstract: Soil and petiole samples were collected from fifteen grape orchards of Kashmir. The pH of surface soils showed significant and negative correlation with nitrogen (r = -0.722) and phosphorus (r = -0.590) and significant and positive correlation with calcium(r = 0.571). Soil surface organic carbon showed positive and significant correlation with available nitrogen (r = 0.904), phosphorus (r = 0.856), sulphur (r = 0.566) and iron(r = 0.592).The petiole nitrogen, phosphorus and sulphur content of vineyards exhibited significant and positive correlation coefficients (r = 0.650, 0.899 and 0.538) with available nitrogen, phosphorus and sulphur content in surface (0-30 cm) soils, respectively. A significant and positive correlation (r = 0.672 and r = 0.715) was observed between petiole manganese and boron with available manganese and boron in surface soils, respectively. Soil and leaf analysis must be used for proper diagnostic and prognostic work for determination of nutritional needs of vineyards.
