Factors Affecting Maize Yield in Machakos County
Abstract
Maize is the main staple crop for many people in Kenya. It is a high yielding cereal grown almost
in all parts of the country mainly under rain fed environmental conditions. However, despite the
fact that maize is the main subsistence crop there has been structural maize deficit in Kenya which
has pushed the prices of maize and maize products up beyond affordable level of many households
leading to food insecurity. This forced the country to import maize from other countries to cover
the shortage and also provide subsidized maize flour at ksh 90 per 2kg packet. There are various
factors that affect maize yield and therefore research was aimed at assessing the factors that affect
maize yield in Machakos County. The research targeted mainly small-scale and large-scale
farmers in Machakos County. The study sought to achieve the following objectives: To examine
the maize production and yield trends for the last 10 years in Machakos County. To find out the
factors that constrain realization of high maize yield in the county. The research was conducted
between July and November 2017 and involved random selection of farmers by visiting them and
receiving direct responses from them as they answered the questionnaires. Through the field visits;
The questionnaires, interviews and field observations provided the study with primary data.
Secondary data was obtained from the Ministry of Agriculture (MOA), National Cereals and
Produce Board (NCPB) in Machakos and Kenya agricultural research Centre (KARLO) in
Machakos. After data collection, the research findings were analyzed using graphs, frequency
tables and percentages and also in regression to establish the relationship between maize yield
and the explanatory variables. The research found that maize yield in Machakos county is affected
negatively by prolonged droughts and shortage of rainfall due to weather variability, poor soils
most of which are very acidic and others are highly alkaline (MOA 2014), lack of agricultural
advisory services, lack of essential inputs. The research shall greatly benefit the farming
communities comprising of both small scale and large-scale maize producers and also traders of
either maize products or farm inputs. The study shall help the farmers to identify the relationship
between output and variables that affect the yield they get from their farming activities.
