Fruit yield is directly related to the nutrient status of leaves as well as soil correlation studies confirmed that the leaf nitrogen before flowering and after harvest and Phosphorus content before flowering were positively and significantly correlated to yield. A similar beneficial association of soil nitrogen and Phosphorus before flowering with yield was evident. High yielding trees had higher rhizosphere as well as leaf N, P, K status. Multiple regression studies recommended for proper N and P fertilization by means of which yield level of the orchards can be raised to higher extent.
