... These findings contradict those of Kimani (2018) who found that small proportion (33%) of respondents perceived that Metal Silo technology maintained the quantity and quality of stored grains. Likewise, Gladstone and Hruska (2002) found that about 60% of the respondents were found to have maize grain in their silos at the beginning of the next harvest in comparison with only 29% of the non-users.

This study assessed small-scale maize farmers' knowledge and perception on the use of improved postharvest storage technologies in Kilolo District, Tanzania. The participants of the study include 260 farmers who were randomly selected from four villages. Data were collected by using interview schedule, questionnaire, Focus Group Discussions (FGD) and personal observation. Descriptive statistics such as means, frequencies, and percentages were computed. The study found that majority of respondents had low knowledge on the use of improved postharvest storage technologies. However, majority of the respondents had positive attitudes towards the use of improved postharvest technologies. It is recommended that Kilolo District Council and other development partners should promote the use of improved post-harvest technologies to reduce maize post-harvest losses; develop training programs on capacity building of extension officers and farmers on postharvest handling of maize and ensure that maize postharvest storage technologies are made available to farmers at a subsidized price.
