Sustainable Intensification of Maize-Legume Systems for the Eastern Province of Zambia-Africa RISING (SIMLEZA-AR) Project Sustainable Intensification of Maize-Legume Systems for the Eastern Province of Zambia-Africa RISING (SIMLEZA-AR) Project
Enhancing adoption & adaptation of GAPs (maize/legume cropping)Enhancing adoption & adaptation of GAPs (maize/legume cropping) Soybean processing and product developmentSoybean processing and product development Maize and legume variety diversification and enhancing seed deliveryMaize and legume variety diversification and enhancing seed delivery
Good Agricultural Practices (GAP) Timely planting & weeding Inoculation of legumes ( soybean) Crop rotation/ associations (intercropping) Soil cover ( mulching) Application of recommended fertiliser rates Pest and disease management
Field visits in February 2015 On site discussions with host farmers & neighbors in each camp
Baby CA demonstrations 4 drought tolerant maize varieties under CA Maize & cowpea rotation under CA Weed control using herbicides in CA
827 farmers hosted ‘’Baby CA’’ demonstrations across 7 camps827 farmers hosted ‘’Baby CA’’ demonstrations across 7 camps 28 farmers hosted ‘’Mother CA’’ trials across 7 camps28 farmers hosted ‘’Mother CA’’ trials across 7 camps Baby CA demonstrations in each agricultural camp (2014/15 season)
Maize Productivity under different CA and CV manual systems
Maize productivity under different tillage practices (Mechanise system)
Cumulative Distributions of Soybean Yields ( )
Cumulative Distributions of Maize-Soybean Rotation Benefits ( )
Benefit Cost Ratios (Maize-Soybean Rotation)
Lessons SI technology benefits are context specific (state contingent) SI technology benefits are most apparent in down-side risk mitigation
Adaption of SIMLEZA-AR technologies to farmer circumstances Timely weed management – Herbicide use, maintaining recommended mulching levels, intercropping Variety choice ( Maize & legume) according to farmer circumstance, seasonal quality and agro-ecological season Adapting CA principles to farmer circumstances Inoculation & rotation of maize and legumes to improve yields
Environmental Impact Improved soil & water use efficiency Improved nutrient recycling Improved soil health? Carbon sequencing? Reduction of aflatoxin levels – through use of mulch ? Negative impact of herbicides on the ecosystem ? Reduction of downside risk ?
Mature Technologies Improve maize & legume varieties ( DT) Mechanised CA – Animal drawn Rippers Manual CA - Dibble stick Soybean inoculation Maize-legume rotations/ intercropping Weed management strategies– herbicides and soil cover

Scaling out cont.…..., Established partnerships – with public extension system and NGOs Training of extension agents, healthy workers, technicians & lead farmers 5 Msc & 1 PhD student Hands on training on use of mechanised CA equipment (rippers, direct seeders, jab planters) Safe use of herbicides 3 publications in peer reviewed journals
Conclusion Strong extension services to improve adoption & promote sustainable intensification practices required (maize-legume intercropping, maize-legume rotation, inoculation of legume seeds etc) required Further understanding of adoption & dis-adoption dynamics of sustainable intensification practices/technologies. A need for alternative cover crops in area where livestock is an important component of livelihood strategies (reduce crop-livestock competition) Improved time and budget allocation on documentation of research results
