Combining soil fertilization, cropping systems and improved varieties to minimize climate risks on farming productivity in northern region of Burkina Faso por Sanou, Josias, Bationo, B. André, Barry, Silamana, Nabie, Loyehoun Dorothée, Bayala, Jules, Zougmoré, Robert B.

“…**Conclusions** Making weather forecasts and related agronomic advices available to farmers in this region will allow them to better plan their agricultural practices such as mineral fertilizer application and will also be a great move toward climate-smart agriculture. Developing more performant storage measures that drastically reduce insect attacks for some of the tested varieties (cowpea KVX 61-1, for instance) could contribute to promoting their adoption.…”
