Seed Quality Crisis: The Silent Factor Holding Back Tanzania’s Farm Productivity

When discussions turn to Tanzania’s agricultural productivity challenges, attention often focuses on fertilizer use, irrigation, mechanization, or climate change. Yet one of the most critical and overlooked determinants of farm output is seed quality. Research and field experience consistently show that seed quality alone can influence up to 40% of crop yield outcomes, even before other inputs are applied.

Despite this, a large share of Tanzanian farmers continue to rely on recycled farm-saved seeds or counterfeit seeds purchased from informal markets. These practices silently suppress yields, increase vulnerability to pests and diseases, and undermine national food security. Unlike droughts or floods, poor seed quality does not attract headlines, but its economic impact is profound and persistent.

Addressing Tanzania’s seed quality crisis is therefore not just a technical matter; it is a foundational step toward agricultural transformation and income growth.

The Current Seed Landscape in Tanzania

Tanzania’s seed system consists of public research institutions, private seed companies, agro-dealers, and informal seed networks. While certified seeds for crops such as maize, rice, beans, and sunflower exist, their availability and accessibility remain uneven especially in remote rural areas.

As a result, many farmers recycle seeds from previous harvests for multiple seasons. Over time, these seeds suffer from genetic degeneration, low vigor, and declining resistance to pests and diseases. In parallel, counterfeit and fake seeds have increasingly entered the market, often sold in packaging that imitates legitimate brands.

For farmers, the consequences are not immediately visible at the point of purchase but become painfully clear at planting and harvest time.

Market and Regulatory Challenges

1. Limited Supply of Certified Seeds

Certified seed production in Tanzania remains insufficient relative to national demand. Public breeding programs face funding and capacity constraints, while private seed companies focus mainly on high-demand crops and commercially attractive regions.

This leaves many farmers without access to quality seeds for secondary crops or in marginal areas.

2. Weak Enforcement and Counterfeit Seeds

Regulatory oversight of seed markets is often limited by insufficient inspection capacity and weak enforcement mechanisms. Counterfeit seeds thrive in informal markets where traceability is low and penalties are rarely enforced.

Farmers purchasing seeds from these markets bear all the risk, with no recourse when crops fail.

3. High Prices and Affordability Constraints

Certified seeds are more expensive than recycled or informal seeds. For smallholder farmers operating on tight budgets, the upfront cost becomes a major barrier especially when the benefits of quality seeds are not fully understood or guaranteed.

Productivity and Economic Costs of Poor Seed Quality

The use of low-quality seeds has cascading effects across the agricultural value chain. Low germination rates force farmers to replant, increasing labour and seed costs. Crops grown from poor-quality seeds are often less uniform, more susceptible to disease, and less responsive to fertilizer and water.

At the household level, this translates into unstable yields, unpredictable incomes, and food insecurity. At the national level, it results in lower aggregate production, higher food prices, and increased reliance on imports.

In effect, poor seed quality traps agriculture in a low-input, low-output equilibrium, limiting the returns on all other agricultural investments.

Way Forward: Fixing the Foundation of Productivity

1. Strengthen Seed Certification and Enforcement

Seed certification and inspection systems must be reinforced through improved funding, staffing, and enforcement capacity. Regulatory authorities should intensify market surveillance, crack down on counterfeit seeds, and introduce stronger penalties to deter illegal traders. Clear labeling and traceability mechanisms will help farmers identify genuine certified seeds.

2. Expand Local Seed Production and Multiplication

Tanzania should scale up local seed production through partnerships between public research institutions, private seed companies, and farmer groups. Locally multiplied seeds are often better adapted to local agro-ecological conditions, reduce reliance on imports, and lower costs for farmers while improving availability in remote areas.

3. Improve Farmer Education and Extension Services

Extension services must prioritize seed quality awareness by demonstrating the yield and income differences between certified seeds and recycled or fake seeds. On-farm demonstration plots and seasonal training programs can help farmers make informed input investment decisions.

4. Improve Affordability Through Innovative Financing

To address cost barriers, certified seeds should be bundled with input credit, crop insurance, or output markets. Targeted subsidies, voucher systems, and cooperative-based purchasing can further improve access for smallholder farmers.
