Nitrogen and Phosphorus Responses of Sorghum and Corn in Uganda
1971
Jowett, David
Seven fertilizer trials testing rates and combinations of N and P were conducted on corn (Zea mays L.), a grain sorghum variety [Sorghum bicolor (L) Muench.] and a sorghum hybrid in Uganda in 1964. In general, corn outyielded sorghum, and showed a better response to applied fertilizer, but the interpretation of the results was complicated by a puzzling significant negative NP interaction for sorghum. The results support the hypothesis that sorghum is better adapted to low soil fertility than is corn in Uganda, but such a conclusion cannot be established on the basis of such slender evidence as is here made available.
