Conteúdo: 	Field experiments were conducted to quantify the effect of Ca supplied as gypsum in factorial combination with watermelon (Citrullus lanatus(Thumb) matsum and nakaij cultivars Charleston Gray, Crimson Sweet ,a dn Tri-X Seedless on yield and the elemental concentration of leaf andrind tissue. Also, the effect that ontogenetic changes and sectional differences had on the elemental concentration in rind tissue was investigated. The experiments were conducted at two locations in Iklahoma. Yield was not affected by Ca; however, mean melon weight was reduced at 1120 kg Ca/Ha. Leaf  Ca concentration increased  linearly in response to Ca rate. Tri-X-Seedles had lower leaf Ca and higher K concentration than  did Charleston Gray or Crimson Sweet . Fruit ontogen(day fromanthesis) and melon section (blossom or stem-end) interacted to affectelemental concentration in the rind tissue. There was also a significant genotypic effect on elemental concentration in rind tissue. Increasing rates of Ca applied to soil reduced the incidence of blossom-end rot (BER) in Charleston Gray melons. Calcium treatment did not affect flesh redness of soluble solids concentration (SSC) of  watermelon.
