Methods of correcting zinc deficiency in irrigated maize grown on a black earth locations
Aims

To present a comparison of soil and spray applications of zinc for maize.

Key messages
  • Soil application of zinc sulphate heptahydrate and zinc oxide increased grain yield of maize when applied in drills near the seed.
  • Spray application of zinc also increased yield but to a lesser extent.
  • Spray applications of zinc following soil application of zinc sulphate or zinc oxide did not give further yield increases.
  • Zinc oxide dusting of seed appears to be a promising remedial technique.
