Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

Creator:: Lamb, Michael J.
Abstract:: Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. Crimson Sweet) was seeded in a commercial peat mix in multicell containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990. In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no CaC0₃ amendment was made. Watermelon seedling...
