Cucumber

This crop requires a warm temperatures (~29 °C daytime) and high light intensity. It perform best on sandy or well-structured organic soils. It can tolerate slightly acidic soil pH values (>5.5) and it is sensitive to salinity. Special attention must be given to N nutrition, since a deficiency in this element can result in misshaped fruit. Cucumber plants are highly demanding for potassium and calcium. While calcium is required at similar rates as nitrogen, potassium is required at about 80% higher rate.
