Twenty representative peach orchards of Sirmour district of Himachal Pradesh were surveyed for assessing their nutritional status using soil and leaf analyses. Soil analysis revealed low status of available N in 95 and 55% orchards in 1992 and 1993 respectively. Leaf analysis showed low status of K in 40% orchards in 1992. All the available nutrient elements showed significant positive relationship with their respective leaf nutrient status. Correlations of available soil nutrients and leaf nutrients with fruit yield and some quality characteristics were also significant. Multiple regression equation of fruit yield on leaf nutrient status showed sensitivity of fruit yield to changes in leaf N and P status.
