Abstract

In pot trials, wheat was most sensitive to soil Cu deficiency followed by barley, oats and rye. There were sufficient differences in sensitivity between the various varieties of wheat, oats and barley. Cu-deficient plants of oats and barley produced low grain and high straw yields, mainly through profuse tillering. In wheat, Cu deficiency resulted in a reduction in the number of developed grains. Applying CuSO4 at 50 kg/ha raised the Cu content of oats and wheat foliage until the crop reached a height of 20 cm, and thereafter it decreased until ear emergence. Responses to Cu of sensitive oat varieties compared with insensitive ones were larger in soil- than in water-culture.-M.S.M. (Abstract retrieved from CAB Abstracts by CABI’s permission)
