On-Farm Green Manure Cover Crop (GMCC) Intercropping Strategy Trial under Conservation Agriculture

This study contains data originated from on-farm trials that were conducted to provide viable options to smallholder farmers to improve soil fertility and human nutrition, to increase biomass for fodder and groundcover and to enhance the resilience of current farming systems against the negative effects of climate variability and change. Green manures or cover crop were used as the option. The trials were conducted at farms in Chipata and Lundazi districts of the eastern province of Zambia. The following treatments were used for the trial:

Sole cropping maize

Maize – Pigeonpea intercropping

Maize – Pigeonpea intercropping with 60-day cowpea

Maize – Dolichos Lablab intercropping

Maize/Gliricidia sepium/pigeonpea intercrop (year 1: groundnuts/Gliricidia; Year 2 soybean/pigeonpea/Gliricidia; year 3 Maize/Pigeonpea/Gliricidia
