Agronomic value of seeds with high nutrient content locations

To present a summary of some field trials investigaitng seed micronutrient contents in barley.

Key messages
  • At Wangary SA when barley seed with a high manganese content was sown there was an increase in yield beyond that achieved with managnese fertiliser.
  • Seed produced from manganese deficient or marginal soils can have low manganese, post anthesis foliar sprays can increase grain manganese conentration and improve the growth of a crop sown from that seed.
  • At Marion Bay SA the timing of manganese spraying during grain fill was not critical.
  • Yields of barley grown from barley seed gathered from a number of different sources and sown at a Callington SA correlated very strongly with the concentrations of copper and zinc in the sown seed.
