Pwalugu Trial Feeds a Published Study on Onion Seedling Density

Our first onion cycle at Pwalugu didn’t just teach us a lot on the ground — it also fed into a peer-reviewed study:

Ablordeppey, P., Azirigo, T., and Amackson, G. (2026). Statistical Estimation of Onion Seedling Density: A Planning Framework for Smallholder Traditional Farms in Pwalugu, Ghana [version 1; peer

review: awaiting peer review]. Open Research Africa, 9:69. doi.org/10.12688/openresafrica.16571.1

The paper builds a planning framework for estimating seedling density on smallholder traditional farms — directly relevant to the nursery challenges we ran into during Cycle 1, and to how we’re approaching nursery planning for the cycles that have followed.

We’re glad to see field experience translate into something usable beyond our own operation, and we’re looking forward to more research collaborations like this one as later cycles close out.
