Abstract
Abstract Background Quality seed is at the core of the technological packages needed to increase crop production, nutrition, and rural wellbeing. However, smallholder farmers in Tanzania have limited access to affordable quality seeds, and over 90% of seed sown is saved by farmers from previous harvests, though its quality is often poor. The Good Seed Initiative (GSI) aimed to enhance access to quality African indigenous vegetable (AIV) seed in Tanzania, through the promotion of farmer seed production, using two models—contract farming and Quality Declared Seed (QDS). This study assessed post-GSI project sustainability factors and explored the prospects for replicating the approach in a wider regional context. Methods The study was conducted in Arusha and Dodoma, targeting locations where the GSI project was implemented. Qualitative tools employing focus group discussions (73 men, 69 women), and key informant interviews were used for data collection. Results Farmer seed production under both models continued to thrive, creating avenues for income diversification and contributing over 50% to household incomes. Farmer seed production contributed to increased availability of quality seed for vegetable growers, especially in central Tanzania that is less served by the formal sector. However, QDS production was challenged by a lack of access to foundation seed, inspections, and seed testing services, which are key for quality seed production. Conclusions Results reveal unequivocally that farmer seed production offers a potentially sustainable solution to the problem of seed supply while providing income benefits for seed producers. The market-based approach used by the project and partnerships with the formal sector, coupled with stimulation of demand through nutritional awareness campaigns, were strong contributory factors to the survival of farmer seed production. Farmer-led seed systems, especially QDS, deserve support from the government to develop a tailored and appropriate seed system that meets the ever-evolving needs of smallholder farmers. Adoption gender-inclusive approaches, particularly in contract farming is paramount to benefit women as much as men.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
