Scientific Name: Citrullus lanatus
Common Varieties: Seeded--Sangria, Fiesta, Calsweet. Seedless--Fandango, Super Cool, Nova, Laurel, Millionaire. Seedless Miniature--Precious Petite, Petite Perfection, Solitare, and Extasy
Seeded Varieties, or Diploid, are oblong and dark green with broken, light green stripes. The flesh is bright red with black seeds. Seeded varieties are not as popular as Seedless varieties, or Triploid. More common is the transplanting of these varieties, instead of direct seeding, because of low seed vigor. A watermelon plant seldom produces more than 2 to 3 harvestable fruit. Melons are unusually harvested by hand and shipped in sturdy cardboard boxes containing 1,100 to 1,200 lbs. Rind scarring reduces marketability but does not detract from fruit taste.
Growers consider soil and water conditions, fertility, and pest pressures to decide economically viable growing practices.
Watermelons grow best in sandy loam or silt loam soils. They are deeply rooted, yet required precise irrigation management to avoid prolonged saturation of the root zone, which would promote root rot pathogens. Watermelon has moderate nutrient requirements compared with other vegetable crops, and due to its deep rooting, it is efficient in extracting nutrients from the soil. One to two bee colonies per acre should be placed in the field when male flowers begin to appear. Poor pollination often causes misshapen fruit. Whiteflies, cutworms, beet armyworms, aphids, spider mites, darkling ground beetles, leafhoppers, cabbage loopers, and leafminers are the most serious insect pests of watermelon. Common diseases include powdery mildew and fusarium wilt.
