Abstract
The fertilizer responsiveness to macronutrients of `Woodard' was investigated to obtain the data for the recommended rate of fertilizer application in a rabbiteye blueberry. One-year-old rooted cuttings of 'Woodard was grown under water culture in 1991. The plot was consisted of 13, a control (application rate: N-28, P-30, K-40, Ca-40, Mg-24 ppm) and 12 high volume application plots of macronutrients (applicated 5 times that of the control). The growth (dry mater per bush) was most superior in the N+Mg plot, most inferior in the N+Ca, the other plots was medium. As compared with the control, the growth of N+Mg, P+K, P+Ca, P+Mg, K+Ca, K+Ca+Mg and Ca+Mg plots was better than the control, and the growth of N+K, N+P+K and K+Mg plots was below. The concentration of macroelements in leaves of the control plot was low among all of. In each plots of high volume application of macronutrients, the concentration of the macroelements in leaves with some exceptions, became high, and the interaction between nutrient elements was confirmed. The difference of the growth of `Woodard' was considerd to be caused not only by the excess of some macroelements but also the imbalance of certain elements in the leaf and root.
