Grain Legumes Contribute Immediate and Residual-Effects in Rain-fed Maize Production Systems

Within-season effects of intercropping are receiving increasing attention. However, the rotational performance is rarely investigated across seasons, even though the two are complementary strategies providing spatial-temporal crop diversification.

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.

Soil Organic Matter Regulates Maize Productivity and Fertilizer Response in Maize Production

Resource-constrained systems need strategies that focus on striking a balance between maintaining SOC above a critical value to ensure high agronomic fertilizer use efficiency and avoiding accumulations of nutrients to levels that prevent viable nutrient use efficiency.

2025 Annual Photo Contest Results

We’re excited to announce the results of our annual photo contest! Thank you for the incredible submissions from across Africa. Your participation helps us showcase nutrient deficiency examples and plant nutrition research, raising awareness about healthy soils and crops, and sharing interesting activities and perspectives about agricultural R&D in Africa.

Agricultural Development in Maize and Rice: Yield-Area Dynamics, Agronomic Strategies, and 4R Nutrient Management Opportunities

Maize and rice exhibit distinct trajectories. World Maize shifted from intensification to extensification, reflecting a move from technology-driven gains to land-based growth. World Rice has maintained intensification, likely due to land constraints in key regions. These differences highlight how crop biology, growing conditions, and socio-economic factors shape agricultural strategies.
