Changing sowing dates has been a farming low-cost strategy to mitigate climate induced water stress during the juvenile stage of crops. This study evaluates the potential of drought-tolerant maize varieties and fertilizer microdosing to enhance maize productivity under different sowing dates in rainfed conditions. We conducted a two-year strip split-plot trial with three sowing dates (early,...
ABSTRACT: Maize productivity depends on grain‐filling, which requires understanding the interactions among genotype, water and nutrient management. However, these interactions remain poorly investigated in Sub‐Saharan Africa (SSA). This study investigates the influence of supplemental irrigation (SI) and fertiliser microdosing on grain‐filling and yields of maize varieties. Field experiment...
The biophysical field-based evaluation of the endogenous soil and water conservation (SWC) practices in the hilly region of sub-Saharan West Africa is lacking. To address this, the current study aims to evaluate the most commonly used erosion control practices in the hilly region of Boukombé through a rainfed field experiment conducted under sorghum over two growing seasons (2012–2013) on a...
In sub-Saharan Africa, smallholder farming systems continue to record very low yields despite the availability of appropriate crop management technologies. A 2-year field experiment was conducted in 2018 and 2019 at the Agricultural Research Station of Northern Benin to evaluate the growth response, grain yield attributes, and nutrient- and water- use efficiencies of different drought-tolerant...
Fertilizer microdosing is being widely promoted across sub-Saharan Africa, yet all recommendations regarding this technology are derived from short-term studies. Such studies are insufficient to properly assess the production risk caused by climatic variability. To address this issue while avoiding costly long-term experiments, a common and well accepted strategy is to combine results from...
