Farmer-led Field Trials - Maize/Millet-Legume Cropping Systems

Objective

To carry out farmer-led field trials of sustainable agriculture intensifications (SAIs) maize/millet-legume cropping systems (Table 1) by integrating with innovative extension and advisory services (EASs) and institutional approaches.

Outputs

  • Greater biomass yield (>6.4 t/ha) with sorghum-legume (e.g. in Tanzania)
  • Land equivalent ratio >1 under intercrop than sole crop (e.g. in South Africa)
  • More than 50 percent of the respondents were food secure (Fig. 3)
  • Large no. of farmers reached through EASs on SAIs, Malawi (30000), Rwanda (11000), Kenya (9000), South Africa (8000), Ethiopia (2000) and Tanzania (236)

Outcomes/impacts

  • Maize/millet-legume yield increased by 17- 49 percent than sole crop (Fig. 2)
  • Enhanced food & nutrition security (Fig. 3)
  • Potential to improve soil fertility
  • Increased knowledge and adoptions by smallholders
  • Greater climate adaptation/resilience
  • Increased efficient use of land
