Agronomic survey to estimate actual yield obtained by farmers in their own practices and relation with management strategies (CIAT)

Estimation of yields of the two crops was undertaken on two representative sections of a field on plots 10 m by 10 m. Data taken on each of the plots included agronomic practices undertaken including plant spacing, pest and disease control, organic/inorganic fertilizer applications and field history according to a protocol implemented in AfSIS. Each field was geo-referenced.
