Product Development

A decision support tool on best planting practices for cassava systems in SW Nigeria and Eastern zone of Coastal Tanzania.

Overall Goals

Demand-driven, rapid, cost-effective development of relevant decision support tools guiding farmers (through extension agents) in choosing best suited planting practices for cassava and intercrops; mainstream approaches for adoption by public and/or private sector in development (NGOs).

Primary Client

Extension agents and farmers of development organizations: CAVA-II and Oyo State Cassava Growers Association (OYSCGA) in Nigeria, and Mennonite Economic Development Associates (MEDA) in Tanzania (with a focus on weed control – introduced in year 2).

Product Development Protocol

  • Identify planting practices that contribute to maximizing cassava root yields, conserve the natural resource base and require least labour and capital investment
  • Develop draft recommendations from existing literature on best planting practices (V0)
  • Define AoIs for compatible planting practices to support cassava intensification
  • Establish the status quo of cassava production through “crowd sourcing” of cropping practices and related yield data; include soil sampling at yield mapping locations
  • Design and conduct field research on best combinations of planting practices including tillage, ridging, planting densities and fertilizer application to develop V1
  • Validation in subsequent season
  • Design and format tool to facilitate use by development organizations (VF)

Tool Format

Best Planting Practices Expert Application for crop advisors (software application, paper-based manuals and extension guides)

Outcome Goals

Best planting practices for selected AoIs by country; protocol for optimal planting density by variety and system, optimal tillage regime by soil conditions and fertilizer use
