Participatory rural appraisal of farmers' maize selection criteria and production constraints in the moist mid-altitude Zone of Kenya
(CIMMYT; KARI, 2002)
Maize is a staple food for most households in Kenya and is grown in almost all agroecological zones. The yield of maize has not kept up with the rate of population growth, leading to serious food insecurity. A major reason ...
A general guide to data preparation for computer analysis of farm survey data
If a computer and an appropriate program for survey data analysis are available, the researcher has to decide whether or not these computer facilities should be used to analyse the survey data or whether an analysis by ...
