Standardization of Leaf Sampling Technique for Macronutrients in Apricot under Temperate Conditions
Macro- and micro-nutrient content influenced by position of leaf on the shoot and time of sampling was studied to determine leaf-sampling time for apricot grown in temperate region of the country. Results revealed that middle order leaves were the most suitable for determining nutrient needs in apricot trees. Leaf samples should be collected during June - July for determining N, K and Ca; first fortnight of July for P; and, from mid-June to mid-July for Mg.
