ADOPTION OF MAIZE AND WHEAT TECHNOLOGIES IN EASTERN AFRICA: A SYNTHESIS OF THE FINDINGS OF 22 CASE STUDIES AgEcon
Doss, Cheryl R.; Mwangi, Wilfred; Verkuijl, Hugo; De Groote, Hugo.
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 from 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...

Adoption of Maize Production Technologies in the Coastal Lowlands of Kenya AgEcon
Wekesa, E.; Mwangi, Wilfred; Verkuijl, Hugo; Danda, Milton Kengo; De Groote, Hugo.
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...

An analysis of the bottlenecks affecting the production and deployment of maize seed in Eastern and Southern Africa AgEcon
Langyintuo, Augustine S.; Mwangi, Wilfred; Diallo, Alpha O.; MacRobert, John F.; Dixon, John; Banziger, Marianne.
The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and...

An analysis of the challenges of the maize seed industry in eastern and southern Africa AgEcon
Langyintuo, Augustine S.; Mwangi, Wilfred; Diallo, Alpha O.; MacRobert, John F.; Dixon, John; Banziger, Marianne.
The liberalization and restructuring of the seed sector in eastern and southern Africa (ESA) during the past two decades have witnessed a proliferation of private seed companies in the maize seed industry (Hassan et al., 2001; Lemonius, 2005). Although the total number of registered maize seed companies increased from 8 and 11, respectively, in 1997 to 40 each, the quantities of seed marketed barely doubled, increasing from 23,000 and 27,000 tons to 53,000 and 51,000 tons, respectively; an indication that the reforms are insufficient in ensuring efficient functioning of the sector in the two regions. A study involving 117 seed providers, representing 92 percent of all registered maize seed companies in ESA in 2007 identified bottlenecks that have...

Does Adoption of Improved Maize Varieties Reduce Poverty? Evidence from Kenya AgEcon
Mwangi, Wilfred; Mwabu, Germano; Nyangito, Hezron Omare.
Adoption of technologies that increase farm yields is a prerequisite for poverty alleviation in agrarian societies. However, the link between adoption of improved agricultural technologies and poverty reduction is not well understood or documented. This relationship is explored with an example of improved maize seed adoption in Laikipia and Suba - two rural districts in Kenya. We show that adopters of improved maize varieties have higher yields per acre and that poverty is negatively correlated with technology adoption. Policies for increasing diffusion of these technologies include improving access roads to market centers to enhance maize profitability and extension of information about improved maize varieties to farmers.

FACTORS AFFECTING ADOPTION OF IMPROVED MAIZE SEEDS AND USE OF INORGANIC FERTILIZER FOR MAIZE PRODUCTION IN THE INTERMEDIATE AND LOWLAND ZONES OF TANZANIA AgEcon
Kaliba, Aloyce R.; Verkuijl, Hugo; Mwangi, Wilfred.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm trials for varietal evaluation and demonstration purposes.

Fertilizer Use and Maize Production in Sub-Saharan Africa AgEcon
Heisey, Paul W.; Mwangi, Wilfred.
In sub-Saharan Africa, greater use of mineral fertilizers is crucial to increasing food production and slowing the rate of environmental degradation. Regional growth rates in fertilizer consumption have never been particularly high, in part because the real price of fertilizer is higher in Africa than in many other developing regions. As subsidies have been removed and exchange-rate distortions corrected over the past decade or more, relative prices paid by farmers have risen to reflect more closely the economic cost of fertilizer. Consumption growth has thus slowed even more. Nonetheless, during the period of declining growth in consumption, fertilizer use on cereals, particularly maize, has become relatively more important than use on cash crops....

Household Resource Endowment and Determinants of Adoption of Drought Tolerant Maize Varieties: A Double-hurdle Approach AgEcon
Legese, Getachew; Langyintuo, Augustine S.; Mwangi, Wilfred; Jaleta, Moti; La Rovere, Roberto.
Existing literature suggests the influence of household wealth on farmer's technology adoption decisions. In 2007, this study was conducted to provide a clearer understanding of how differences in household wealth affect the way in which other variables influence adoption decisions. Using data from 369 households in Adama and Adami Tulu Jido Kombolcha districts of Ethiopia, the paper first stratified households into poorly and well-endowed categories based on wealth indices constructed using their productive assets by the principal components method. A double hurdle model was then specified and estimated for each wealth group to assess factors influencing the adoption and use intensity of improved varieties. The results suggest that factors influencing the...

MAIZE BREEDING RESEARCH IN EASTERN AND SOUTHERN AFRICA: CURRENT STATUS AND IMPACTS OF PAST INVESTMENTS MADE BY THE PUBLIC AND PRIVATE SECTORS, 1966-97 AgEcon
Hassan, Rashid M.; Mekuria, Mulugetta; Mwangi, Wilfred.
This report documents the impacts of international maize breeding research in eastern and southern Africa. It draws on information from a comprehensive 1998/99 survey of public and private maize breeding and seed production organizations active in the region. In many countries of eastern and southern Africa, policy reforms introduced in the 1980s and 1990s encouraged private sector participation in the maize seed industry. The private sector now supplies most of the maize seed in the region, spends more on research, and generates a larger number of maize releases than the public sector. Hybrids dominate varietal releases and seed sales, a trend that may negatively affect subsistence-oriented farmers who lack resources to buy fresh seed every season....

The Seed Industry for Dryland Crops in Eastern Kenya AgEcon
Muhammad, Lutta; Njoroge, Kiarie; Bett, Charles; Mwangi, Wilfred; Verkuijl, Hugo; De Groote, Hugo.
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...

Wheat Farmers' Seed Management and Varietal Adoption in Kenya AgEcon
Gamba, Paul; Ngugi, Caroline; Verkuijl, Hugo; Mwangi, Wilfred; Kiriswa, Frank.
Wheat is the second most important crop in Kenya after maize and is becoming an important source of food both for humans and livestock. Despite increasing wheat production, only 50% of domestic consumption requirements are being met. While the National Plant Breeding Research Centre at the Kenya Agricultural Research Institute has released more than 100 wheat varieties since it began operations in 1927, adoption has been slow in spite of better performance of new varieties. This study examined factors that influence farmers' adoption of new varieties in the Narok, Nakuru, and Uasin Gishu Districts that account for 80% of Kenya's domestic wheat production. The study found that most farmers in these Districts neither knew nor grew new wheat varieties,...
