Eggplants(Solanum melongena L. var. Hibrida F1 Piracicaba nº 100) were grown in pots containing 7 kg of pure quartz. Twice a day they were irrigated by percolation with complete nutrient solution. Every ten days from the 35th day, plants were harvested, divided into aerial part and fruits and analysed for N, P, K, Ca, Hg and S. Data obtained allowed for the following main conclusion: a) The initial rate of growth of the eggplant during the first 66 days is rather slow. b) The uptake of macronutrients is samll until the 66 days increasing with the age of the plant. c) The maximum absorption rate according to the element in decrease order is: K, N, Ca, Mg, P and S. d) The following amounts of element in kg/ha were absorved by a population of 20.000 plants with 20.000 kg harvested:
