Leaves from the highbush blueberry cultivars ‘Bluecrop,’ ‘Bluejay, ‘Blueray,’ ‘Collins’ and ‘Spartan, growing in a mineral soil with sawdust mulch, were sampled in early August for three years (1986-88) and analyzed for N, P, K, Ca, Mg, Fe, Mn, Cu and Zn to determine cultivar leaf elemental content differences. Differences among cultivars for elemental content were found for all elements analyzed except Mg, Fe, Cu, and Zn. Differences among sample years was significant for all elements. The data reveal that large enough differences exist among the cultivars sampled to warrant separate leaf samples for each in commercial blueberry fields.
