In cotton-growing areas, sowing of cotton and cereals, especially maize and cowpea, is almost exclusively manual, which mobilizes a large workforce, but also often causes low densities affecting yields. In addition, these manual sowing leads to a waste of seeds which are increasingly expensive, especially for transgenic cotton (Bt cotton), hybrid maize and cowpea. In addition, the organic restitutions little practiced by the producers, do not make it possible to make good use of the small quantities of organic manure applied heterogeneously on the fly. In this context, it is important to mechanize the operations of sowing crops and spreading organic manure for the intensification of production systems.
The implementation of this project by a multidisciplinary team, is based on a participatory approach through the development of prototypes of seed drill and organic manure spreader as well as evaluation and validation tests of this equipment in producers.
