The response of barley to foliar and soil applied zinc was studied at fire low soil zinc sites in south‐east Scotland over two season. None of the treatments increased the grain yield at harvest. Of the treatments studied only foliar applied zinc sulphate consistently increased the zinc content of plant tissue, and this was more marked when a split application of 2·5 + 2·5 kg ha −1 Zn was used as opposed to a single treatment of 5 kg ha −1 Zn. It is concluded that at the present time there is no evidence that zinc is limiting the yield potential of barley when grown on low zinc soils in this part of Scotland.
