Bouchareb Radia

Hydroponics is very present in horticulture and in the intensive cultivation of certain fruits and vegetables. It accelerates the fruit ripening process through at a faster nycthemeral rate and allows several harvests per year. This research was done in a glass greenhouse at Constantine University1. In the NFT (Nutrient Film Technique) system, on four varieties of the tomato: Campbell33 (India), Super Strwh (USA), Coeur de boeuf (Algeria), Heinz1350 (USA).

 the objective of our experiment is to cultivate these varieties of tomato under the conditions of hydroponic culture, as well as in the various nutritive solution with a substrate of clay biles (a natural support), and to study the morphological parameters ( plant height, number of leaves, leaf area), and the phenological parameters to the installed system and compared the development of the varieties with each other.
