|Maize (Zea mays L), is from Spanish: maíz after Taíno mahiz, known in many English-speaking countries as corn, is a grain domesticated by the Olmec and Mayans during Mesoamerica in prehistoric times. In the late 15th and early 16th centuries, the European explorers and traders carried maize from America to Europe and introduced it to other countries. The Adoption of Maize in Africa occurred during the British occupation, from the late 19th century.
In fact, until the 1920s, most of the maize produced by European settlers in Kenya was exported, not eaten domestically. The first “scientific” maize research program began in Kenya in Kitale in 1955.

|Income Per Hectare: Kshs 120,000 (60 bags * 2000/-)Cost per Hectare: Kshs. 50,000 (40% of Income)
NET Kshs. 70,000 (60% of Income)
Break Even Yield (Where Cost=Income) = 18 bags per hectare.
