    “…The main lack of success was highly linked to the extrapolating approach of one site success to others without considering the climate, soil, and ecological setting and variations. As a result, a new fertilization approach was desperately needed, and with this premise, new blended fertilizers are now being introduced to replace the conventional approach. …”

    “…Due to the popularity of cassava-maize intercropping and the food security and economic importance of both crops in Nigeria, we investigated options to improve interception of photosynthetically active radiation (IPAR), radiation use efficiency (RUE), soil moisture retention, and yields of cassava and maize in cassava-maize intercropping systems in 8 on-farm researcher-managed multi-location trials between 2017 and 2019 in different agro-ecologies of southern Nigeria. Treatments were a combination of (1) maize planting density (low density at 20,000 maize plants ha(-1) versus high density at 40,000 maize plants ha(-1), intercropped with 12,500 cassava plants ha(-1)); (2) fertilizer application and management targeting either the maize crop (90 kg N, 20 kg P and 37 kg K ha(-1)) or the cassava crop (75 kg N, 20 kg P and 90 kg K ha(-1)), compared with control without fertilizer application. …”
