Publication - Guidelines for the quality control of Quality Protein Maize (QPM) seed and grain(CIMMYT, 2016) Twumasi Afriyie, S.; Palacios-Rojas, N.; Friesen, D.; Chere, A.T.; Dagne Wegary Gissa; De Groote, H.; Prasanna, B.M.This guidebook is the first of its kind to provide recommendations and a framework for monitoring quality assurance of QPM. Guidelines are based on QPM genetics, breeding, characteristics, and nutritional benefits. It lists the QPM varieties based on CIMMYT germplasm that have been released worldwide. Furthermore, it elucidates the concepts of seed quality control, seed production and certification systems, definition of protein quality in QPM, methods for laboratory analysis of protein quality in QPM, sampling procedures for submitting samples to the lab, and sourcing a laboratory for analysis; it also gives recommendations for quality control in both QPM grain and recycled seed. This technical bulletin is intended to serve mainly as background information based on which to develop national QPM seed and grain quality control and assurance standards in countries where QPM is produced and marketed.
Publication - The seed industry for dryland crops in Eastern Kenya(CIMMYT, 2003) Muhammad, L.; Njoroge, K.; Bett, C.; Mwangi, W.M.; Verkuijl, H.; De Groote, H.The development and promotion of improved crop varieties as well as efficient seed production, distribution, and marketing systems have contributed significantly to increased agricultural production and food security in Kenya. However, these impacts have not been replicated in the semi-arid midlands due to climatic, soil, and institutional factors. Following the liberalization of agriculture in the late 1980s, there has been greater participation of the private sector, non-governmental organizations, and voluntary agencies in the area. This study examined the extent to which these developments affected farmers’ access to dryland crops. The study found that the low quantity of seed traded, high cost of production, and high seed supply prices constrained the development of local seed trade. It recommended developing and offering a range of varieties to farmers to increase demand, training to strengthen farmers’ capacity to manage seed onfarm, and reduction of high production and distribution costs through further research and institutional improvements. In addition, the “seed loans” model, which has been very effective in the area, should be strengthened.
Publication - Adoption of maize and wheat technologies in Eastern Africa: a synthesis of the findings of 22 case studies(CIMMYT, 2003) Doss, C.; Mwangi, W.M.; Verkuijl, H.; De Groote, H.This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, Kenya, Tanzania, and Uganda during 1996-1999. The authors found that technology adoption is taking place across Eastern Africa but considerable scope remains to improve the productivity of smallholder agriculture in higher potential regions with high levels of adoption. Extension was the variable most highly correlated with technology adoption, and extension services continue to play an important role in disseminating information on new varieties and how to manage them. Despite the usefulness of the micro-study results, especially for priority setting and impact assessment, future adoption studies can be improved by standardizing definitions across studies and using sampling techniques that allow results to be generalized across wider areas. Finally, the paper suggests that maize and wheat breeding research should be made more relevant to the preferences and circumstances of farmers, that the link between research and extension should be strengthened and include the private sector and non-governmental organizations, that policies should support the development and expansion of efficient markets for inputs and outputs, and that rural credit systems should be strengthened.
Publication - Adoption of maize production technologies in the coastal lowlands of Kenya(CIMMYT, 2003) Wekesa, E.; Mwangi, W.M.; Verkuijl, H.; Danda, K.; De Groote, H.Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers cited poor availability of improved varieties, high cost, lack of knowledge, and unfavourable characteristics of improved varieties as reasons for non-adoption. The high price and poor availability of fertilizers, farmers’ inexperience with them, and their perception that soils were already fertile were among reasons given for low fertilizer use. The low levels of adoption of improved varieties indicate that they are not meeting farmers’ needs. The authors recommend that researchers communicate with and include farmers’ criteria when breeding varieties. In addition, alternative options should be extended to farmers who are not able to use inorganic fertilizers. Finally, given the major influence of the institutional environment found in the study, it is recommended that extension services be strengthened, especially where lack of knowledge was cited as a hindrance to adoption.
Publication - Adoption of maize seed and fertilizer technologies in embu district, Kenya(CIMMYT, 2002) Ouma, J.O.; Murithi, F.M.; Mwangi, W.M.; Verkuijl, H.; Gethi, M.; De Groote, H.This study reviews socioeconomic and technical factors that affect the adoption of improved maize and fertilizer in the Embu District, Kenya and the role of credit in both. A total of 127 farmers (82 adopters and 45 non-adopters) were interviewed for the study during the long and short rainy seasons in 1998 in the Nembure, Runyenjes, and Kieni Divisions in Embu District. Most farmers in the study area used basal fertilizer. However, the use of fertilizer was below recommended levels. More adopters used hired labor and had greater access to credit and extension services than non-adopters. The Pioneer H3253 variety and 2-kg seed packages were found to be most popular among adopters. Agroecological zones, gender, manure use, hiring of labor, and extension services were found to be statistically significant in explaining adoption of improved varieties. Similarly, agroecological zone, gender, manure use, hiring of labor, and extension services were important in explaining the amounts of basal fertilizers farmers used.
