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 Battery middle order leaves T-Clear 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.
