Abstract

The effect of Na-accumulation on the growth and production of sweet-pepper was tested in a trial in stone wool with full recirculation. Four concentrations from 0 to 10 mmol/l at two K/Ca ratios were tested. No significant effects on production or quality were established. The uptake of Na was very low; only a few tenths mmol/l. On the basis of the results of this test, the limit value for discharge may be increased to 8 á 10 mmol/l. However, since the intake of Na is very low, the requirement of high quality water for sweet pepper remains unaffected.
