Read the scientific evidence before planning sweet potato production, healthy vine purchases or a processing contract. Ipomoea batatas is distinct from potato.
Gmakouba and co-authors assessed 65 Togolese and 16 exotic varieties using a 9 × 9 lattice design and 16 quantitative traits. They identified four groups with differences in root yield and dry matter. The table shows group means, not national averages or guaranteed farm yields.
| Group | Root yield, t/ha | Dry matter, % |
|---|---|---|
| I | 12.95 | 29.68 |
| II | 15.87 | 26.86 |
| III | 16.06 | 24.62 |
| IV | 20.18 | 23.84 |
Variety trial; not a national statistic or a yield promise.
The authors call for agronomic and phytosanitary assessment over at least three years in different zones, plus genotyping. Observed phenotypic diversity alone does not prove stable resistance to viruses or weevils. Select for fresh sales, flour, chips or purée, considering dry matter, flesh colour, storage and consumer acceptance.
Ministry documentation describes cultivation across several zones, with historical importance in Maritime. Southern planting references include May and August; crop duration varies by cultivar. Confirm Apomuden, Nane and local variety identity with competent services. In March 2025 FSRP reported distribution of 1.8 million basic vine cuttings to multipliers and women producers. This is a programme event, not current saleable inventory.

Agree field drainage, healthy cutting source, rotation, calendar and pest monitoring with local advisers. Harvest and grade to limit wounds and decay, then document storage and actual losses. Potential yields in extension sheets are not contractual forecasts. No pesticide dose or profitability promise is inferred from this study.
Compare fresh roots, flour, chips, purée and food processing. Buyers should specify flesh colour, variety, size, target dry matter, tolerances, net weight and delivery. Confirm phytosanitary eligibility, packaging and keeping quality before a container-level commitment. HS 071420 covers sweet potatoes within that heading’s scope; flour and processed products may need other codes. No unverified 2026 national production volume is announced.
Specify product, variety, origin, container-level volume, packing, date and named port. Price, stock and acceptance require a confirmed offer.
