Young plants of Allium schoenoprasum were cultivated in pots containing fine pure quartz. The plants we re, irrigated periodically with complete nutrition solution for 30 days after this period the plants were submited to solutions lacking one of the following elements - N, P, K, Ca, Mg, S and B. After 35 days the plants exhibited malnutrition symptoms and where cutted near to the surface of the pots. The material was dried at 80°C and analyze for the elements. The plants were let to re-grown for another 43 days and submited to the same treatments. It was very dificult to recognize the malnutrition symptons for the different nutrients. The omission of N affected markedly the grow of the plants. Calcium deficiency and nitrogen deficiencies affected the leaves quality, besides the time of senescence. A population of 200,000 plants/ha contents 12.2 kg/n; 3.8 kg/P; 11.4 kg/K; 3.2 kg/Ca; 2.4 kg/Mg; 1.5 kg/s and 16.9 g/B.
