The influence of variety, date of planting, spacing of plants, rate of nitrogen fertilization, and irrigation on the iron, zinc, manganese, and copper contents of wheat was studied. The correlation of mineral content and yield with protein content as well as the relations among the mineral elements were studied. There were significant correlations among iron, zinc, and copper. None of the correlations involving manganese were significant. Zinc showed a significant negative correlation to yield and a positive correlation to protein content. Iron and copper were also correlated negatively to yield and positively to protein content, but the correlations were not significant. The manganese level was independent of yield and protein content. Only irrigation and late planting, two treatments which increase soil moisture, resulted in higher levels of iron, zinc, and copper, but not of manganese, in wheat.
