Characteristics of community seed schemes for grains and legumes: Insights from northern Nigeria

CONTEXT: Despite the significant roles that intermediary seed systems play in the supply of quality seeds in developing countries, including Africa south of the Sahara, the knowledge gap remains generally substantial regarding the general characteristics and seed quality control performance of intermediary seed systems such as community seed schemes (CSS), which still operate predominantly outside the formal seed systems. OBJECTIVE: We aim to narrow the knowledge gap on seed production practices implemented by CSS, their economic and technical characteristics, the extent of seed quality control achieved, and potential challenges CSS is facing. METHODS: Using primary survey data of seed producers of key grains (maize, rice, and sorghum) and legumes (cowpea and soybean) from 380 CSS in Kano state in northern Nigeria, we qualitatively assess origins and drivers of their growth, extent of seed production, relations with upstream actors (breeder and foundation seed providers) and downstream actors (seed buyers), economic structures of their seed production, aspects of quality control measures they engage, and potential roles of external support, such as training on the implementation of these quality control measures. RESULTS AND CONCLUSIONS: We discovered that many of the interviewed CSS have emerged endogenously, taking up seed production to address the challenges in access to quality seeds in their locality. Their seed production has often grown into viable businesses that have provided potentially significant additions to their incomes. Oftentimes, these CSS implemented some seed quality control measures, including making closer visual checks of seeds, checking germination rates, and bagging/packing seeds, among others. However, fuller seed quality control may be significantly skill-intensive, and most CSS still do not implement many of the recommended measures under some of the intermediary quality assurance standards, such as Quality Declared Seed. Our qualitative assessment suggests that future support for CSS can focus on technical support to raise the ability to engage in broader categories of quality assurance activities in economically viable ways and to improve the awareness and knowledge of different varieties and access to foundation seeds. SIGNIFICANCE: The quality assurance provided by existing CSS in Nigeria may be relatively limited, particularly in proper maintenance of the seed production field and the quality of original seeds that CSS intend to multiply. Providing external support through training and technical assistance can be an effective way to transform community seed schemes into critical providers of seed quality assurance in the intermediate seed system and to fill gaps in the formal seed system.

Supply- and demand-side factors affecting maize and cowpea varietal turnover and quality seed use: Mixed-method evidence from northern Nigeria

This study provides an integrated assessment of the seed system for maize and cowpea, two of the most important crops in Nigeria. We analyze the various factors influencing seed supply and demand and present different measures of capacity and incentive of multiple actors along the seed value chain. We also present metrics on adoption of improved varieties and quality seed use, given the complexity of these concepts and persistent challenges in measuring them in a survey context. At the national level, the 2015 to 2018 Living Standards Measurement Survey data show that the adoption rate of improved varieties was 16 percent of maize area and 6 percent of cowpea area, with 9 percent of maize farmers and 3 percent of cowpea farmers reporting certified seed use of improved varieties. Data from household surveys conducted in 2022 show that in Bauchi and Kaduna—states with relatively high maize and cowpea production levels—the adoption rate of quality seeds of improved varieties was 10 percent of cowpea land area and 25 percent of maize land area. In addition, the improved varieties in the cowpea and maize plots were old; the area-weighted varietal age in cowpea farms was 12 years and in maize farms, 13 years. The most popular cowpea variety was Kananado (likely matching released variety SAMPEA 9 or SAMPEA 11, released in 2005 and 2009, respectively), and the most popular maize variety was SAMMAZ 15, released in 2008. Newer varieties have not caught up in popularity. Different stages of the seed value chain face major bottlenecks. Two major themes emerged as barriers and drivers of adoption of newer improved varieties and quality seed: (1) Seed supplies were limited, especially breeder and foundation seeds, implying that Nigeria’s seed system needs to increase coordination, funding, and capacity for early-generation seed production and management; and (2) new varieties were not promoted to farmers, who therefore lacked exposure to the seeds, implying that both public and private sectors need to invest more in the promotion of these varieties and increase exposure and testing among farmers. There is also a need to look at the breeding and offerings of newer improved varieties. Some newer varieties do not consistently and comprehensively outperform older bred varieties in field trials and farm demonstrations; some older bred varieties remain attractive and popular to farmers. Beyond seeds, several contextual factors disabled farmers’ and seed actors’ capacity and incentive to expand production and adopt improved varieties. Security issues; poor soil conditions; and high fertilizer, transportation, irrigation, and diesel costs were some of the major disablers in the seed system that must be addressed.
