Manure use in two villages of central upper VoltaABonkianauthorIn order to estimate minted crop production budgets under farmers' conditions in central Upper Volta, the ICRISAT West Africa Economics Program undertook a farm-management study in 1980 at Nakamtenga and Nabitenga, two villages 35 kilometers (km) northeast of Ouagadougou (see Matlon 1980a and Matlon 1980b for a description of the general objectives of the study). In the course of the study, it was observed that farmers used various types of animal manures--pig, sheep, goat, cattle, donkey, chicken--in their Nelda. As a management practice with potentially important effects on productivity, manure use seemed to warrant a more detailed analysis.
