Maize and beans constitute a major diet in many parts of Uganda and the two crops are commonly intercropped. For a long time farmers have been growing their own local maize varieties which tend to be susceptible to diseases like maize streak and northern leaf blight (Exserohilum turcicum). The local varieties are known to be low yielders and relatively late maturing. However, with the popularisation drive of the improved varieties like Longe 1 several farmers have come to embrace this variety notably for its ability to withstand drought, and mature early and give good yields.
