Young Sesbania plants were grown in nutrient solutions for the purpose of studying deficiency symptoms of the following elements: N, P, K, Ca, Mg, S, and B. The present paper describes the symptons on Sesbania plants that were associated with nutrient solutions defficient in the various elements listed. The paper presents also the satisfactory range and defficient range in the leaves: N% 3.12 - 1.70; P% 0.25 - 0,03; K% 2.10 - 0.15; Ca% 1.32 - 0.56; Mg% 0.47 - 0.09; B ppm 77 - 23. The sulphur concentration in normal plants was 0.16%.
