Determination the importans of nitrogen, phosporous and potassium in water-culture technique

This research has been carried out in Çanakkale Onsekiz Mart Agriculture FacultiesPlastic greenhouse with randomized plot design and with 3 replications.Meltem F1 tomato variety which had been rooted in peat and used as a researchmaterial, in research, five different nutrient solutions, included water, used and plantsplanted in stable nutrient solutions.I-WaterII-Complete solution which includen all nutrient.III-Complete solution-Nitrogen which includen all nutrients except NitrogenIV-Complete solution-Phosphorous which includen all nutrients exceptphosphorousIV- Complete solution-Potassium which includen all nutrients except PotassiumSolutions has been prepared upon on Hoogland and Arnon (1950), Luck (1956),Stainer (1958)?s researches. Considering the plant length, plant stem diameter, air-driedroot and stem weights and pheonological observations, the best results obtained from -Nitrogen and complete nutrient solutions. Water and - Potassium subjects gave the lowestvalues in terms of given parameters.Key Words: Nutrient Film Technique, Hydroponics System, N-P-K
