摘要

The study was carried out to improve farmers’ awareness, enhance the adoption of full package sorghum production technologies. The large-scale demonstration was implemented at Gololcha woreda of Arsi zone for one year (2019/2020) using Melkam variety. The demonstration was implemented in three kebeles and a total of 100 hectares of land was covered by participating 117 household heads (farmers) out of which 12 of them were women-headed. In the demonstration farmers contributed a land size of 0.25 hectares (the minimum) and 2 hectares of land (maximum). Totally, from the demonstration 4030 quintals of sorghum were harvested with 42.3 quintals per hectare average productivity. The yield obtained by farmers practices w</span><span style="font-family:Verdana;">as</span><span style="font-family:Verdana;"> 18.23 q</span><span style="font-family:""><span style="font-family:Verdana;">&middot;ha</span>^{<span style="font-family:Verdana;">-1</span>}<span style="font-family:Verdana;"> which is lower as compared to the average yield obtained by large scale demonstration.
