Abstract

Young Tobiatã plants were cultivated in pots containing pure fine quartz and irrigated with nutrient solutions lacking one of the following elements: N, P, K, Ca, Mg, S, B. Four pots recieved nutrient solutions with all essencial elements. Clearcut picture of the deficiencies was observed in all treatments. Leaves of normal and deficient plant showed the following concentrations: N% 2.20-1.22; P% 0.21-0.09; K% 2.96-0.39; Ca% 0.67-0.04; Mg% 1.46-0.05; S% 0.16-0.10 and Bppm 8.1-12.
