Doubled-Up Legume Systems Under Conservation Agriculture and Conventional Agriculture in Sinda, Chipata, and Lundazi, Zambia

This study contains data originated from on-farm trials that were conducted to test and demonstrate the crop yield and economic benefits derived from conservation agriculture (CA) systems on smallholder farms where the ridge and furrow tillage system is the traditional practice. The farm trials were conducted at six farms in Chipata, Lundazi, and Sinda districts of the eastern province of Zambia. In each site, the trials were replicated four times and had two general treatment sets:1)conservation agriculture; and 2) Conventional ridge and furrow systems.

The sub-treatments were:

  • Sole cropping groundnuts
  • Sole cropping pigeonpea
  • Full population of groundnuts + half population of pigeonpea
  • Full population of groundnuts and pigeon
  • The trials were conducted over multiple years:

  • Year 1: Legume phase
  • Year 2: Maize phase + legume phase
  • Year 3: Legume phase + maize phase
