All melon varieties are heavy potassium-feeders, as they require K at rates 2.4-fold higher than nitrogen. Melons prefer deep soils, well-supplied with organic matter and a pH around neutral. Melons tolerate slightly alkaline or salty soils and are fairly resistant to moderate drought, but normally need irrigation. The crop requires warm temperatures and high light intensity. Optimum growth temperatures are 18–20 °C and 24–30 °C, for night and day, respectively. Best melon mineral nutrition regime includes the use of CRFs, fertigation with fully-soluble fertilizers and foliar feeding.
