Abstract

Synopsis Eight iron chelate formulations applied on field plots of flax and safflower did not increase seed yields. Seed oil content and iodine value of oil were not affected except in one case when an increase in iodine value was associated with a decrease in seed yield. Nitrogen fertilization depressed iodine value of oil and seed oil content but increased seed yields.
