For years, the arithmetic of Tanzania’s seed supply has worked against its own farmers: more than half of the certified seed planted every season has had to be imported, grown elsewhere and sold back to a country that has both the land and the demand to grow it at home. That is the number a new plant in Arusha is quietly trying to move.

On 9 September 2026, Agriculture Minister Hon. Daniel Chongolo (MP) opened Seed Co Tanzania’s new seed-processing and warehousing facility in Engorora village, Kisongo Ward — a TZS 18 billion investment on a 7,100-square-metre footprint, built to push the company’s locally produced share of seed from 42 percent two years ago to roughly 50 percent today. It is a single factory. But read against where it sits in Tanzania’s seed system, and who helped put it there, it is also a marker of how far — and how deliberately — that system has been rebuilt over the past decade.

How a Seed Company Became a Corridor Partner

Seed Co’s presence in Tanzania did not start with a processing plant. It started with soybeans.

In 2016, the then-SAGCOT programme launched the Soya Strategic Partnership in Iringa to close a domestic feed deficit and build outgrower networks where none existed at commercial scale. Seed Co supplied the inputs, working alongside anchor off-taker Silverlands and aggregator Caritas to bring more than 3,200 smallholders in the Songea/Ruvuma area into a formal supply chain for the first time — and secured, through SAGCOT-facilitated permits, the right to import and multiply certified soybean varieties (Safari, Spike, Semeke, Squire) that gave Southern Highlands farmers disease tolerance they had not had access to before.

From there, the relationship deepened rather than simply repeated. By 2020, Seed Co was co-chairing the Mbarali Cluster Green Reference Group alongside the Songwe Regional Administrative Secretary — a shift from supplying a cluster to helping govern one, coordinating climate-smart agriculture and input-use standards among commercial investors and cooperatives. The same year, after joint government field missions confirmed the scale of Tanzania’s cereal deficit, Seed Co was formally engaged as a national partner in wheat seed supply, aimed at a wheat import bill that was then running above USD 220 million a year.

The infrastructure to back that ambition came from a 350-hectare commercial farm at Mazombe/Ilula in Iringa, run with Farm for the Future since 2018. Under centre-pivot irrigation across 193 of those hectares, the partnership now produces more than 1,000 tonnes of certified hybrid maize seed annually — seed that has helped some farmers move from 3 MT/ha to as much as 15 MT/ha, a five-fold jump that no amount of extension advice alone could have delivered without the seed itself being available.

Between 2021 and 2024, that footprint widened again through the Iringa Soybean Commodity Compact — fourteen partners, including AGCOT, Shafa Agro, TARI, PASS Trust and TADB, working to guarantee certified seed for organised cooperatives — and the Norway-funded Tanzania Sustainable Soybean Initiative, which got certified seed to more than 21,000 profiled farmers across seven regions. By the time SAGCOT formally became AGCOT Centre in April 2025, Seed Co was positioned to be one of the corridor model’s clearest proof points: a private company that had grown, region by region, alongside the public financing and governance structures built around it — most recently through a potential TZS 1 billion Equity Bank credit package for seed multipliers in Ludewa District, meant to fund the next stage of expansion into Tanzania’s Mtwara, Central and Northern corridors.

Arusha, in other words, is not where this story starts. It is where a decade of smaller, regional commitments converged into a single facility large enough to matter nationally.

The Fight That Matters More Than the Ribbon-Cutting

None of that history solves Tanzania’s two hardest seed problems, and both were on the table at the Arusha launch.

The first is counterfeit seed. Seed Co Group Chairman Pearson Ngowero used his remarks at the opening to name the problem directly: fake and illegally traded seed, he said, robs farmers of income, undermines productivity, erodes trust in the formal seed system, and threatens food security outright — a farmer who unknowingly plants counterfeit seed risks an entire season’s investment on something that was never going to yield. Minister Chongolo’s response was equally direct: government, he said, has a duty to protect farmers from this, and will pursue firm enforcement, including sanctions, against anyone manufacturing or distributing fake seed. Tanzania Seed Traders Association Executive Director Baldwin “Bob” Shuma framed the stakes in blunter economic terms still: every kilogramme of seed the country imports, he argued, is effectively a job exported abroad — and closing that gap is what the private sector says it is trying to do.

The second problem is reach. A processing plant, however large, only matters if what comes off its line gets to a farmer who can use it correctly. Rather than let seed companies each build their own parallel field networks — an approach that tends to concentrate service near processing hubs like Arusha and leave more remote growers behind — Chongolo pressed Seed Co to formalise a contract with government’s new national extension agency, which is meant to place officers in every village nationwide, with performance tracked under that agreement. It is a less photogenic commitment than a ribbon-cutting, but it is arguably the one that decides whether a 50-percent-local seed supply actually reaches the roughly six million farming households the sector is meant to serve, or stays concentrated around the regions already best connected to it.

What Success Looks Like From Here

Seed Co has already signalled where the next stage goes: a second processing and warehousing facility, a new research station, and production spreading into the Lake Zone, the Southern Highlands under the SAGCOT corridor, and potentially the Central Corridor. If that expansion holds to the timeline the company described, it would repeat in several more regions what a decade of cluster partnerships slowly built around Iringa and Mbarali — outgrower contracts, local jobs, seed grown close enough to where it is planted that a bad season for imports doesn’t become a bad season for supply.

For Engorora village itself, the near-term gains are more immediate: jobs at the plant, a scholarship fund for ten students, a repaired access road, and a primary school getting infrastructure support. For Tanzania’s wider seed system, the more meaningful test is still ahead — whether the extension contract gets signed, whether counterfeit enforcement has real teeth, and whether the next two plants arrive on schedule. If they do, a country that has spent a decade rebuilding its seed system one corridor partnership at a time will have a genuine claim to something rarer than a new factory: seed it actually grew itself.
