Effect of overlap between the sodium chloride andproline acid in bearing tomato plant (Lycopersiconesculentum Mill.) Some of the nutrients using hydroponic system *

Abstract

The experiment was Carried out using hydroponic unit mside the glass house belonging to the Department Biology, Faculty of Education (Ibn al-Haytham) / University of Baghdad during, the growing season 2010-2011 in order to study the effect of concentrations of sodium chloride and proline and their interaction on the content of nitrogen, phosphorus, potassium , calcium and magnesium of shoot of two cultivars of tomatoes (Hymar F1, Olga F1).The concentrations of sodium chloride used was 0.100 and 150mM/L and prolineconcentrations was 0, 15 and 30 mg/ liter. A factorial experiment within completely randominzed design (CRD) was used with three replicacates. Means were compared using LSD test at 0.05 probability level. The letel experiment units were (3x3x3x2) when equals to 54. Plants were grown in or plastic container hydroponically (static hydroponics). Hutrientsolution were changed 48 hours intervals. The pH of the nutrient solutions was adjusted, aerates wae used by using compressor. Plants were sapled at 32 and 54 days from transplanting to the hydroponic system, which up rested H1-D32 and H2-D53. Results revealed the superiority of Olga F1 cultivar on the Hymar cultivar of all studied dements
