This project addresses the problems of low digestibility of sorghum stover and low access of small producers to improved dual-purpose sorghum varieties and hybrids in sorghum-based production systems in the Sudanian zone of Mali, where pressure for livestock feed is increasing and opportunities for crop-livestock integration are greatest. The main objective is to contribute to increasing farmers income, nutrition and resilience through the use of dual-purpose sorghum and sorghum-based cropping systems in the zone. The project also aims to exploit sorghum germplasm diversity for stover and grain traits to enhance total crop value; identify agronomic management options for maximizing total value of grain and stover in dual-purpose sorghum and legume production; identify dual-purpose cowpea varieties for grain/fodder adapted to the sorghum-based production systems; develop equations for rapid predictions of the chemical composition and the nutritive value of sorghum stover and cowpea fodder using NIRS techniques; and assess the feasibility, profitability, and farmers preferences for intensified dual-purpose sorghum and cowpea production options in their socio-agronomic conditions.
