A greenhouse experiment was conducted to evaluate the response of different soybean genotypes to manganese application. Twenty-five soybean genotypes belonging to different maturity groups were grown in a greenhouse using a Lynch-burg sandy loam soil collected from Sampson County, NC. It is a coastal plain soil deficient in manganese. Manganese rates were 0, 15, and 30 kg per hec-tare. The experimental design was a split plot with three replications.
