About 800 million people in the world of developing nations do not have enough food to meet their basic nutrient needs and requirements (FAO, 2014). Drought, over dependency on rain fed agriculture and lack of agricultural funds have been the major contributors to these problems. Also continued rise in price levels has attributed to lower savings and consequently reduced purchasing power among the poor to achieve food security and earn a living free of hunger (Fofana, 2006). Hunger kills people every year than AIDS and Malaria combined (FAO). Maize output reached 1,018 million tons, 0.7 percent above the recorded output in 2013. The expansion in world maize production was mainly in China and the United States, as well as significantly higher outputs for the EU and the Russian Federation. Maize was responsible for the bulk of this decline, with total maize imports contracting by 4.5 percent to 114 million tons.Maize is the most important staple food crop in Kenya and contributes significantly to food security. In 2014, national maize production slightly decreased by 2.2 percent from 39.9 million bags achieved in 2013 to 39.0 million bags (90 Kgs ). The marginal decline is attributed to poor rainfall distribution that affected the Central, Eastern and Coastal regions which normally produce a higher proportion of the crop. However, production of the crop was stabilized by fairly good weather patterns in North Rift, Western and Nyanza regions during the long rains season. The decline was also as a result of Maize Lethal Necrosis (MLN) disease that affected the crop in Rift Valley region. Western and Nyanza regions recorded a consistent improved maize production in the last three years. More so, the area under production decreased marginally from 2.12 million ha in 2013 to 2.1 million ha in 2014. Overall, maize yields per ha remained fairly constant since 2010.Evaluation of agricultural systems consists essentially of measuring how adequate and effective an existing system has been in achieving its objectives over some past operating phase (season or operating year). There are diverse farming system properties that are normally evaluated, such as generation of maximum net income/profitability of the system in money terms – either directly for market-oriented farms or indirectly by imputation of values for subsistence-oriented farms; sustainability; and environmental compatibility (Dillon and Hardaker, 1993; Upton, 1987). Other key properties of agricultural systems evaluated include productivity, profitability, diversity, flexibility, and time-dispersion. Maize is food and cash crop grown in most farms in Webuye West Constituency. However, the production is not much enough to sustain the rapidly upcoming population in the area. Therefore this study anticipates to find out the possible cause of the low maize production in the region.
