Objectives:

1. To determine the relationship between iron concentrations in bean leaves at early bloom and occurrence of dark pod discoloration in grower fields.
2. To obtain soil samples from the same locations for anlyses.
3. To take plant, pod and sod samples from any fields in which the dark pod discoloration problem is encountered during the 1986 season.
