Improved seed varieties can drastically help improve the food security and livelihoods of small-scale farm families. However, an unreliable seed deployment system in eastern and southern Africa (ESA) prevents many farmers from accessing these benefits. According to a 2007 study conducted among 117 seed providers in 10 African countries in eastern and southern Africa (ESA), low seed sales stem from a faulty extension system, poor infrastructure, and a lack of farmers’ adoption of new seed varieties. This policy brief outlines the obstacles to effective seed marketing and provides a way forward. For further information, contact Augustine Langyintuo at alangyintuo@agra-alliance.org.

There is simply not enough seed in eastern and southern Africa. In this brief, a seed sector survey carried out in 2007 in sub-Saharan Africa explores the barriers to seed production as well as possible strategies in overcoming them and increasing regional seed company productivity. A concise view of the current seed production constraints is given, along with the envisaged solutions to productivity constraints.

In 2006, the Drought Tolerant Maize for Africa (DTMA) project was initiated withthe aim of improving maize germplasm in the drought prone mid-altitude regions ofeastern and southern Africa (ESA). Through this project eight hybrids and four openpollinatedvarieties (OPVs) were developed through multi-location trials under optimal(well fertilized and well-watered conditions), rainfed, low soil nitrogen and manageddrought stress environments. To validate the performance of the new germplasm againstcommercially available germplasm and farmer-preferred varieties, a series of trials wereconducted across 49 farmers’ fields in eight countries in 2010/11 seasons in ESA. Trialswere un-replicated and conducted under farmer management, with farms consideredblocks in a randomized complete-block design. Average trial yields ranged from 0.7 t ha-1 to above 8 t ha-1. Trials were divided into two categories based on yield levels; high yieldingtrials >=3 t ha-1 (n = 30 trials) and low yielding trials < 3 t ha-1 (n = 19 trials). Broad senseheritability of high and low yielding trials was 0.80 and 0.62 to 0.94 and 0.61, respectively,indicating that highly repeatable means can be estimated from un-replicated on-farmtrials in ESA. The best new DTMA hybrids out-yielded the farmers’ own varieties by morethan 35% and 50% under low- and high-yield conditions, respectively, when compared to SC513, the most widely grown commercially hybrid available varieties in southern Africa.
