Abstract

Soil applications of 28-42 Ib ZnSO4 heptahydrate/ac and 12 Ib ZnO/ac increased grain yields of maize when applied in drills near the seed. Spray applications of ZnSO4 also increased grain yields but to a lesser extent, and when following soil applications of ZnSO4 or ZnO did not give further yield increases. Dusting of seed with ZnO appeared to be a promising remedial technique.-F.A.S.
