Iron deficiency depresses growth of furrow irrigated soybean and pigeon pea on vertisols of northern NSW locations
Aims

Examine effect of applying chelated iron to leaves, and chalted iron, zinc, N and P to soils growing irrigated soybean and pigeon pea.

Key messages
  • Chelated iron applied to the soil before sowing increased active iron in leaves by 42% and dry matter by up to 46% early in the season.
  • The 9% increase in grain yield following iron application to soil was not significant.
  • Foliar iron had no significant on activeFe, leaf colour or photosynthesis.
  • Lime induced iron chlorosis was suspected.
