A total of 206 wheat and 200 barley farmers were interviewed in northeastern Syria to understand farmer perceptions and practice relating to modern varieties, seed sources and seed quality. Wheat farmers had better awareness and grew modern varieties (87%), applied fertilizers (99.5%), herbicides (93%), seed treatment (90%) or insecticides (41%). In contrast barley growers had low awareness (36...

seed hardiness in annual medics plays an important role in soil seed bank reserve to ensure ley farming system sustainability. to study the level of seed hardiness in annual medic (medicago scuttelata var.rabinson) at different fertilizing treatments and growing conditions (irrigated and dry farming system), an experiment was conducted at two research stations (sararod, research institute and s...

This research explores the causes of dealer demand amplification leading to a high volume of seed returns in a typical agribusiness supply chain. Seed production occurs months in advance of grower demand, resulting in a limited supply of specific seeds. To hedge against shortages, dealers inflate orders. If demand materializes, dealers benefit from their inflationary behavior. If it does not, t...

High seed quality is a critical component for realising yield potential. Forsmallholder cowpea farmers in northern Nigeria the informal seed system is amajor supplier of genetically high-quality seed, but the physiological quality offarmers’ produced seed remains unknown. The project “Promoting SustainableAgriculture in Borno State” (PROSAB) trained and supported farmers in seedproduction in Bo...

An opto-electronic seed spacing evaluation system that measured time intervals between seeds and detected frontto-back location of seed drop events relative to the planter was used to rapidly determine planter seed spacing uniformity in the laboratory. The seed detection sensor for the opto-electronic system consisted of a rectangular photogate with 24 phototransistors receiving light beams fro...

Seed security is central to crop production for smallholder farmers in developing countries, but it remains understudied relation long-term seed sector development. Here, we compare systems two districts of Central Ethiopia characterized by subsistence-oriented teff cultivation and commercially oriented wheat relate this the country’s pluralistic system development strategy (PSSDS). Our analysi...

Introduction This FAC Policy Brief examines the political and economic processes governing Ethiopian cereal seed systems by analysing the overall policy context, including the main interests driving seed policy formulation and implementation, and the roles and interaction of the different public and private actors. It also investigates how these interests and interactions are related to the act...
