Technical Abstract: Calcium is commonly known to affect the developmental processes of many plants, and its role as a major nutrient has been interpreted in terms of its interaction with components of the cell wall and membrane. A two-year study was conducted to assess the affects of calcium foliar feed fertilization applied at bloom and throughout floral development on the reduction of rain related splitting in blueberries. Foliar applied calcium at 0.2% or 0.9% concentration did not successfully decrease splitting in blueberries to a statistical and more importantly, an economically significant level. Calcium sprays also had no adverse affects on the fruit firmness, quality or calcium concentrations within the fruit.
