Use case 5: Staggered planting

Product development:

decision support tool that provides recommendations on staggered planting practices to ensure a more continuous supply of cassava fresh roots to the processing industry in key areas in Tanzania (and Nigeria)

Overall goals

Demand-driven, rapid and cost-effective development of a tool for staggered planting; demand creation with service providers; mainstream approaches for adoption by national research organizations

Primary client

Product development protocol

(to be validated and refined in a collaborative effort involving IITA, FUNAAB, NRCRI, ARI, CIAT, ETH and KUL)

  • delineate target areas and collate fresh root prices and transport costs
  • assemble a draft version (V0) of the tool based on secondary information
  • conduct researcher-managed trials and a first series of multilocational on-farm validation trials to assess options for staggered planting and delaying harvest
  • use findings to parametrize and cross-validate DSSAT model, conduct additional series of field trials to refine tool (V1-V2)
  • design and format tool to facilitate use by development organizations (VF)

Tool format

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

Outcome goals

A decision support tool for selected AoIs in Nigeria and Tanzania; analytical tools, approaches and protocols for tool development; ROI of the overall R&D approach; prioritized service providers use the decision support tool
