The effects of peat-moss application, nitrogen form (NH4 -N and N03-N) and soil pH on the growth and nutrient uptake of 'Homebell' rabbiteye blueberry (vaccinium ashei Reade) were investigated. Peat-moss and NH4-N applications resulted in the best blueberry growth at pH 4. NH4-N promoted leaf development better than N03-N. The plants grown at pH 6 with N03-N developed leaf chlorosis or leaf scorch. With peat-moss application, the N, P and K contents of leaves, twigs and roots increased at pH 4, both with NH4-N and N03-N. The Ca contents of leaves, twigs and roots were higher at pH 6 than at pH 4, and increased with peat-moss application. The Mg content of roots increased with peat-moss application. The Mn content of leaves was higher at pH 4 than at pH 6. With peat-moss application, the Mn contents of leaves and twigs increased at pH 4 and that of roots decreased at pH 6. The Al content of leaves was higher at pH 4 than at pH 6. With peat-moss application, the A1 and Fe contents of leaves, twigs and roots decreased. Peat-moss may play an important role in blueberry growth in highly acidic soil in terms of preventing the disorders caused by N03-N or soil pH above the optimum range.
