Culture Methods,As previously discussed, soilless culture is the term most frequently used to include all nonconventional soil culture methods, although the term hydroponics is often still found in the literature. Both terms can be used to describe all the general nonsoil growing systems.

Water,Crop yields are more dependent on an adequate supply of water than on any other single factor.

Culture and Cultivation,There are small differences among the optimal nutrient compositions for various crop species. No less important are the differences associated with the development stages of the plant, the seedling-, vegetative-, flowering-, and fruiting-stages.

Types of Hydroponics and Nomenclature,e culture, nutriculture, etc. The word hydroponics was originally used in the United States as a synonym for soilless culture. Likewise, the German Hydrokultur and the English hydroculture have been used to describe this method of farming (Steiner 1976; Jones 1983; FAO 1990).

Plant Growth Effects and Plant Tests,the density of photosynthetic plants on the earth’s surface and the efficiency with which they can absorb light and photosynthesize throughout all the seasons. In contrast, a highly efficient C. plant, such as corn, may utilize 5% of incident radiant energy during its most rapid period of growth.
