Differential varietal response to zinc foliar sprays in navy beans locations
Aims

To determine if zinc deficiency coujld be alleviated with foliar sprays.

Key messages
  • Although soil measures of zinc availability indicated sufficiency, zinc deficiency was severe in the untreated plots.
  • Yield responses to foliar zinc of up to 86% were observed in sensitive cultivars.
  • Some cultivars were not responsive to applied zinc and did not show any symptoms of zinc deficiency.
  • Appropriate early treatment with foliar sprays eliminates zinc deficiency.
  • Where soils are shown to be zinc deficient soil applications may be warranted but interactions with phosphorus need to be understood.
