Soybean (Glycine max. L.) cv. JS 80–21 was grown in refined sand till maturity at deficient (0.3 11M), subnormal (3.0 μM) and normal (30 μM) boron supply. In soybean boron deficiency depressed growth, biomass, pod and seed yield, concentration of boron and ribonuclease activity in leaves and increased that of peroxidase, acid phosphatase and starch phosphorylase. The quality of seeds deteriorated with low boron as refleded in decreased content of boron, starch, protein and oil along with stimulated of concentrations of sugars and phenols.
