Influence of Ironite and Phosphorus on Wheat and Barley on the safford Agricultural Center, 1999

Abstract

Ironite and phosphorus were applied to plots seeded to hard red wheat and barley to find their effect on crop yield and nutrient uptake at various stages of crop development. Phosphorous caused significant increases in yield in both wheat and barley, where Ironite caused few changes in yield. Ironite caused significant increases in percent of nutrients stored in barley grain, but generally had little effect on nutrient uptake by plants at boot or milk stage. Phosphorous tended to decrease the percent nutrient uptake by plants.
