Exploring Climate Smart Cropping System Solutions for Smallholder Farmers
The effects of climate change are threatening the stability of smallholder farmers in Malawi. As such, most farmers are receptive to adaptive strategies such as increased adoption of drought-tolerant crops like sorghum. Here smallholders provide insight into the long-term impacts of climate change, and related field research examines nutrient management within a new grain legume-sorghum cropping system offering food security and climate resilience.

Enhancing Agronomic Efficiency of Fertilizers in Sub-Saharan Africa: Evidence from the Field
Smallholder farmers have faced a myriad of constraints that collectively act to limit the effectiveness of scarce fertilizer input resources. Case study examples provided from the Ethiopian Highlands provide a means to discuss key interventions that can help raise nutrient use efficiency across fields with varying responsiveness to fertilizer application.

Variability in Yield Response Strongly Affects Maize Productivity and Nutrient Requirements
Smallholder maize productions systems in western Kenya exhibited wide spatial and temporal variability in yield responses to N, P and K application at the field level. Nutrient omission trials provide evidence of strong and ubiquitous N limitations and high vulnerability for rapid decline in P and K under continuous cropping without balanced nutrient applications.

Post-Harvest Assessments of On-Farm Maize Experimentation Provide Key Checkpoints for Farmers and Stakeholders
The completion of the most recent maize-growing seasons in northern Côte d’Ivoire and Kenya (western and eastern regions) provided a first opportunity for farmers to share assessments from participating within a new on-farm research initiative for sub-Saharan Africa called NUTCAT - meaning Nutrient Catalyzed Agricultural Transformation.
