Abstract

Significant yield increases were obtained from the application of zinc sulphate sprays at critical times. The effect of spray concentration (0· 5, 1·0 and 1·5%) and frequency of spraying (single or dual applications) was not significant. To be fully effective, sprays had to be appUed at 2 weeks after emergence. Soil applications of 1 cwt of zinc sulphate per acre were fully effective. The lower rates of 28 and 70 lb/ac were not fu]y effective in all trials. The practical implications of these findings is that zinc sulphate sprays applied at 1·0% at 10 gal/ac at 2 weeks after emergence will control zinc deficiency in linseed at a low cost.
