In a foliar spraying experiment, saccharose-metal complexes were sprayed onto flowering stands of soya plants. The area was given basic fertlization prior to autimn tillage. The following treatments were applied: Cu-tetramine and Zn-hexamine hydroxide; Cu + Ni + Mo + Zn-saccharose; Co-saccharose; Cu + Zn-saccharose; Ce-sulphate; Cu + Ni-saccharose. Samples were taken a week before harvesting, from a 1m2 area. The phytotoxic effects of the complexes had been studied under greenhouse conditions two years previoulsy: in a concentration of 0.2 m the scorching effect was less than 1 per cent and no damage was noted in the field experiment. Co-saccharose significantly increased the field experiment. Co-saccharose significantly increased the thousand-grain-weight, promoted the incorporation of Mo into the seed, and increased the essential amino acid content. Favourable results were obtained with the Ce-sulphate treatment and the Cu + Ni-saccharose treatment with respect to the amino acid content, aspecially to the contents of limiting amino acids /lysine, methionine, threonine/.
