%X 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:&quot;\"><span style=\"font-family:Verdana;\">&amp;middot;ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\"> which is lower as compared
to the average yield obtained by large scale demonstration. The technology gap
(TG) was 15.70 q&amp;middot;ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\"> which indicated that technologies have not been adopted. Extension gap was
24.07 q&amp;middot;ha</span><sup><span style=\"font-family:Verdana;\">-1</span></sup><span style=\"font-family:Verdana;\"> and this result indicated that the extension approach should be </span></span><span style=\"font-family:Verdana;\">more </span><span style=\"font-family:Verdana;\">strengthen</span><span style=\"font-family:Verdana;\">ed</span><span style=\"font-family:Verdana;\">. It has been ascertained that </span><span style=\"font-family:Verdana;\">¡°</span><span style=\"font-family:Verdana;\">Melkam</span><span style=\"font-family:Verdana;\">¡±</span><span style=\"font-family:Verdana;\"> variety is the best fitted variety and promotion
of improved sorghum technologies via large scale demonstration has show</span><span style=\"font-family:Verdana;\">n</span><span style=\"font-family:Verdana;\"> a considerable yield increment as compared to
farmers practices. According to the farmers¡¯ trait preference, Melkam variety
was preferred by farmers because of its high yielding, consumption quality,
early maturity, palatability, and drought-tolerant traits respectively. For
sustainable production of improved sorghum technologies, the seed system should
be taken into consideration to deliver the seed supply for the entire sorghum
producers.
