Maize production has increased in the last few years in the region and country. Despite the increase, there are still many problems that are not solved in the production system, among them shelling system or operation is the first. The traditional methods of shelling; i.e. rubbing the cob together, fringe by hand finger, beating the cobs using sick, or by pestle and animal tramping . These methods are labor intensive, time consuming, cause damage, and loss of grains. Improved agricultural technologies are widely recognized as the key means of addressing most of the causes of low productivity. In order to solve the problems the Mekelle Agricultural Mechanization and Rural Energy center improves theBako model Engine operated maize Sheller which have capacity of more than 50-60quintal/hr and 98.9% Efficiency.The overall objective of the project is to enhance productivity of farmers through effective and efficient use of engine maize Sheller.Hence this kind of engine maize Sheller is necessary to demonstrate and further evaluate to benefit small scale farmers. Representative site and farmers were selected. Then training (demonstration and popularization) were given to 143 farmers and Das in 2017. Economic data and farmers’ perception were collected. Descriptive statistics was used for analyzing quantitative data. The simple statistical analysis across all the demonstration sites revealed that the improved engine maize Sheller exhibited higher advantage over the Traditional specially labor and time saving.Because of thecompatibility problems in the current socio economic condition it became unadoptable by small scale farmers but they may own in in group. To resolve this challenge, researchers need to think of its size.However this kind of engine maize sheller is necessary to manufacture and popularize to benefit for large scale producers and cooperatives.
