Manure use in two villages of central upper Volta

In 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
