| Abstract:
A long-term field study indicated the influence of lime, S, and P soil amendments on growth, yield, and leaf nutrient concentration of >Tifblue= rabbiteye blueberry (Vaccinium ashei Reade). The addition of P to the soil did not affect soil concentration of any mineral except P which was increased but resulted in higher leaf K and lower leaf Ca, Mg, Fe, and Mn concentrations. Potassium, Ca, and Mg were higher in soils which were limed. Leaf elemental concentration of Ca and Mg was highest in control plants and was reduced by the addition of either lime or S to the soil. No other elements were influenced by these treatments. Fruit yields in 1998 and 1999 were highest in control plants or plants growing with applied soil S. These plants yielded approximately 4 to 6 times more fruit than plants receiving applied lime. | |
