Variety age and maize yield in Zambia: climate-smart benefits of varietal turnover under production stress
Agricultural productivity growth in sub-Saharan Africa has stagnated despite sustained investments in crop improvement research, with maize yields showing concerning signs of decline since the 2000s. This study examines whether slow varietal turnover (the replacement of older varieties with newer im...
