Does Minimum Tillage with Planting Basins or Ripping Raise Maize Yields? Meso-panel Data Evidence from Zambia.

Raising agricultural productivity to meet growing food demands while increasing the resilience of rain-fed farm systems to climate variability is one of the most pressing contemporary development challenges in Sub-Saharan Africa (SSA). Anchored on the three core principles of minimum tillage (MT), crop residue retention, and crop rotation; conservation agriculture (CA) technologies have been actively promoted over nearly the last two decades as potential solutions to raise farm productivity in the context of increased climate variability.
