CROPGRO-Cotton model for determining climate change impacts on yield, water- and N- use efficiencies of cotton in the Dry Savanna of West Africa

Autor: Paul L. G. Vlek, Kokou Adambounou Amouzou, Christian Borgemeister, Jesse B. Naab, Mathias Becker, John P. A. Lamers

Publikováno v: Agricultural Systems. 165:85-96

Cotton is an important cash crop in many West African countries. Hence, its sustainable production will support the national economies as well as the livelihoods of the farming population alike and in turn help easing wide-spread poverty. However, fu
