Abstract

Three soybean varieties, IAC-2; UFV-1 and Viçoja, were grown in nutrient solution in the presence of both several levels of CI-(as NaCl and KCl) and two Ca+ concentrations (supplied as calcium sulphate). The following main conclusions were drawn: 1) Cl- toxicity, higher when accompanying iom was K+, affected yield formation more than vegetative growth; 2) there were differences in response among the three cultivars, Viçoja being relatively more tolerant; 3) raising the calcium level in the medium contributed to diminish the harmful effect due to excess cloride.
