Determinants of Improved Maize Seed and Fertilizer Use in Kenya: Policy Implications

Maize is a key food crop in Kenya. While maize yields increased from 1.25 t ha-1 in early 1960s to over 2 tonnes in 1982, they fell below 1.5 t ha-1 in 2000. Given the limited land area, there is no doubt that Kenya will have to rely more on modern technologies for increased yields .Use of improved maize varieties and fertilizers will therefore continue to be critical inputs for improving productivity. To improve production, it is important to understand factors determining adoption and intensity of use of modern technologies. A stratified 2-stage sampling design was used to select 1800 households, subsequently interviewed by means of structured questionnaire. Econometric models were used to explore factors influencing adoption and intensity of use of the improved varieties and fertilizer. Access to credit was positively related to adoption and intensity of use of the two inputs. Extension contacts positively influenced the likelihood of adoption of improved maize seed, while amount of planting fertilizer used positively influenced both the adoption and intensity of use of improved varieties. Distance to market negatively determined the adoption and intensity of use of fertilizer. In addition gender and access to hired labour had negative impacts on the intensity of use of fertilizer. There is need to think of alternative sources of credit to farmers and also revamp the existing extension service (including privatization in the long term) for efficient delivery of information.Maize, adoption, improved seed, fertilizer, credit, extension, Kenya, Crop Production/Industries,

Livelihood strategies in the rural Kenyan highlands

The concept of a livelihood strategy has become central to development practice in recent years. Nonetheless, precise identification of livelihoods in quantitative data has remained methodologically elusive. This paper uses cluster analysis methods to operationalize the concept of livelihood strategies in household data and then uses the resulting strategy-specific income distributions to test whether the hypothesized outcome differences between livelihoods indeed exist. Using data from Kenya’s central and western highlands, we identify five distinct livelihood strategies that exhibit statistically significant differences in mean per capita incomes and stochastic dominance orderings that establish clear welfare rankings among livelihood strategies. Multinomial regression analysis identifies geographic, demographic and financial determinants of livelihood choice. The results should facilitate targeting of interventions designed to improve household livelihoods.Livelihood strategy, Kenya, Smallholder agriculture, Cluster analysis, Community/Rural/Urban Development,

The Maize Green Revolution in Kenya Revisited

The maize green revolution, which increased maize yields through the use of improved varieties and fertilizer, has stalled since the mid-eighties in Kenya. This paper examines whether the stagnation of yields continued in the 1990s in spite of the implementation of the maize liberalization policies by the Kenya Government. Analysis of farm level surveys from 1992 and 2002 indicates slight increases in the use of improved maize varieties and fertilizer, but a substantial decrease in the intensity of fertilizer use. The econometric analysis suggests that the intensity of fertilizer use has a major effect on yield. The use of improved maize varieties, however, did not affect yield, suggesting that there are local varieties for some areas that do as well as improved varieties. Research is needed to develop improved varieties for some areas, and also needed for the development of alternative affordable soil fertility measures.green revolution, maize, adoption, soil fertility, Kenya, Crop Production/Industries, International Development,

Economics of Insecticide use and Potential for Bt Maize Varieties in the Control of Stalkborer in Kenya.

Maize is the staple food crop and source of income for majority of the Kenyan population and many sub-Saharan African countries. The increasing Kenyan population demands an increase in maize production if intermittent food deficits have to be averted. Since the introduction of improved maize varieties in mid-1960, the start of Green Revolution period, maize yields increased drastically up to 1970s and started declining from 1980s to-date. The key contributory factors are nutrient mining, sub-optimal input use and insect pest damage. Of the insect pests, stalk borer is of economic importance. Currently, KARI and CIMMYT are developing maize varieties that are tolerant to stalk borer damage. In order to evaluate the potential impact of these interventions economics of stalk borer control at farm level was evaluated. Surveys complemented with on-farm trials were executed in six major maize growing zones of Kenya. Farmers were randomly selected and a sample-frame established after which a total of 1854 households were randomly selected using random sampling technique. Each household was interviewed using structured questionnaire. Data on method of stalk borer control and the type insecticides used was collected. Partial budget and economic surplus models were used. The results indicated that very few farmers control stalk borer in maize despite significant stalk borer losses of about 15%. Therefore if Bt maize is introduced in Kenya it is likely to reduce these losses. This will benefit many hungry and poor Kenyans with improved household food supply and on farm incomes, in line with Government policy of food security and poverty eradication.Crop Production/Industries,

Participatory Farmer Evaluation of Stem borer Resistant Maize varieties in three maize growing ecologies of Kenya

Insect Resistant Maize for Africa Project (IRMA) aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmer’s perceptions and improving the adoption of the developed varieties, participatory approaches are adopted. The paper analysis farmer’s preferences of maize germplasm developed through conventional breeding. The paper uses data collected from evaluations conducted at the end of 2006 April and October rains. Nine stem borer resistant maize varieties were evaluated alongside six commercial checks in the moist transitional zones (East and West) at vegetative and harvest stage, while in the dry transitional zone and dry mid altitude zones, 6 new varieties were evaluated together with four commercial checks at harvest stage. Each variety was assessed on a scale of 1(very poor) to 5 (very good) based on key criteria generated in earlier group discussions with farmers and overall score. Data was analyzed using ordinal regression model of Social Package for Social Sciences (SPSS). In DT zone, Katumani, CKIR06007 and CKIR06008 were more preferred to the checks based on overall score. CKIR06008 was also more preferred on yield and tolerance to insect pest criteria, while CKIR04002, CKIR06009, and CKIR04003 were perceived more superior to local check based on tolerance to insect pests. In moist transitional zone Embu only CKIR06005 was more preferred (p<0.01) to the check at harvest stage in April 2006 season based on early maturity. While there was no preference for the new varieties at vegetative stage in Embu in October rains 2006 season, a number of new varieties CKIR06001, CKIR06002, CKIR06003, CKIR06004, and CKIR06005 were more preferred based on early maturity at harvest in October rains 2006 season. In the moist transitional zone (west), CKIR06005 and CKIR06005 were more preferred on maturity criteria but CKIR06004 also had good attributes in terms of cob size vegetative stage in April rains 2007. We conclude that farmers perceive some varieties to have good tolerance to insect pests in addition to good yield and maturity characteristics attributes, which are critical to the farmers in the adoption of new varieties.Crop Production/Industries,

Markets Access, Approaches and Opportunities for Quality Protein Maize Products

Lack of access to nutritious food is an underlying and major cause of child mortality in Africa. Improving the nutritional quality of food crops, through biofortification, would be a useful complementary strategy to other agricultural and public health interventions. Quality Protein Maize (QPM) varieties have been developed through biofortification. Consumption of these varieties leads to greater protein utilisation in adults and children. In Kenya three QPM varieties have been released. In Central Kenya, particularly Kirinyaga district, farmers have come together through Innovation Platform for Technology Adoption ( IPTA) with the aim of production, value addition and marketing of QPM based products. These groups require information on the potential markets for the new QPM based products. The study was therefore conceived with the aim of collecting and providing information about potential market that can be used by farmers in the IPTAs in deciding how QPM based products should be designed, delivered, priced, and marketed. The study used the Rapid Market Appraisal (RMA) approach. Market outlets in Kirinyaga, Embu and Nairobi were first identified through the guidance of staff of the ministries of agriculture, trade, education, health and local authority. The market outlets were classified as retail, wholesale, schools, hospitals, restaurants/hotels and food stores/processors. 60 respondents in the different outlets were interviewed using separate sets of pretested questionnaires in June-July 2009. 17 questionnaires were not fully completed and were not included in the analysis. Data collected was subjected to analysis using SPSS. Although the awareness level about QPM was low (35 % (n=43), there was desire to buy QPM products. 95 % (n=43) expressed the desire to buy products but required samples of the products before making final decision. The potential demand varied from outlet to outlet but on average there was demand of about 0.8 tons per month. Promotional campaigns need to be intensified to create more awareness and increase demand. Farmers groups will also require to meet quality standards as they produce and market QPM products in the various outlets

Perspectives of gatekeepers in the Kenyan food industry towards genetically modified food

Attitudes and perceptions of stakeholders are crucial in the acceptability of GM foods. Past research focussed on consumers, but paid little attention to the food industry and its gatekeepers, especially in Africa. Therefore, a survey was conducted covering 39 respondents from the milling industry and supermarkets, the main processors and distributors of maize products, in seven urban centres of Kenya. Respondents, mostly from senior management, were well educated and had a good knowledge of biotechnology. Their major sources of information were the media for the supermarkets, and brochures and the food industry for the milling companies. Respondents generally appreciated the benefits of biotechnology, but had concerns about the environment, although few people considered GM food harmful to human or animal health. Most respondents found traceability of GM products important, but would prefer not to label them because of the costs and possible negative consumer reactions. Respondents were largely non-committal on the use of GM products in their companies, preferring to decide on a case-by-case basis. The few negative responses, mostly from the milling industry, were affected by high risk and low benefit perceptions. Most respondents do not like the idea of labelling GM food. Better communication between research and the food industry is now needed, and more research on the labelling of GM products.Consumers Gatekeepers Attitudes Perceptions GM Kenya

ASSESSING THE POTENTIAL IMPACT OF BT MAIZE IN KENYA USING A GIS BASED MODEL

The Insect Resistant Maize for Africa (IRMA) project is currently developing Bt maize for Kenya. So far, Bt genes with resistance to Chilo partellus, Chilo orichalcociliellus, Eldana Sacharina, and Sesamia calamistis, four of the five major stemborers were successfully incorporated into elite CIMMYT maize inbred line (CML216) and tested in insect bioassays in Kenya. Participatory Rural Appraisals showed that stem borers are indeed a major pest problems for farmers. Four seasons of on-farm crop loss assessment showed an average crop loss of 13.5%, or 0.4 million tons, valued at US$80 million. If the project manages to find a Bt gene that is effective to the fifth stemborer, Busseola fusca, adoption rates are likely to be high, and therefore the returns. Under standard assumptions, the economic surplus of the project is calculated at$ 208 million over 25 years (66% of which is consumer surplus) as compared to a cost of $5.7 million. Geographically, the project should focus on the high production moist-transitional zone. However, if such gene cannot be found, Bt maize technology would only be effective in the low potential areas, and adoption rates would be fairly low, although benefits would still exceed costs
