| dc.description.abstract | Sorghum is multi-purpose crop that plays an important role in the socio-economic life of farming communities in Somaliland. Smuts are the most important factors limiting its production. Out of smuts sorghum covered kernel smut disease, caused by Sporisorium sorghi is one of the yields limiting factor of this crop resulting in high yield losses. Both assessment and field experiment were conducted in Gabilay district in Somaliland during 2019/2020 main cropping season. During survey a total of 60 sorghum fields were assessed in three (3) villages of Gabillay district namely; Galolay, Boqor and Agamse. Most fields were affected by sorghum covered kernel smut and their prevalence was ranged from 75% at Agamse to 85% at galolay village. But the status of disease incidence was ranged from 0% to 65.4% and severity varied from 0.0% to 52.5%. The experiment was conducted at Aburin Research Centre of experimental field. The experiment consisted of 12 treatments, viz. three Sorghum varieties (Faruryogele, Abadro and Kuso variety) and four type of seed treatment such as Apron star 42WS%,Cow urine, Neem seed kernel extract and Untreated in factorial arrangement. The experiment was laid out as randomized complete block design (RCBD) with three replications. Parameters as Incidence, severity, phenological data, grain yield (kg)/plot, actual grain yield/plot, 1000 grains weight (g) and yield loss (%) were collected. The experiment result showed that highest disease (44.0%) incidence was recorded on untreated kuso variety while lowest disease (4.33%) incidence was Apron star with Abadiro. similarly, the highest disease severity ((37%) was scored from Untreated Abadiro whereas lowest disease severity (4%) was scored from Abadiro with Apron star and Faruryo gele with Apron star. Untreated Abadiro variety reached highest AUDPC (1036.0% days). The apron star treated varieties had the lowest AUDPC and consistently showing markedly low infection rates indicating that they were more effective to the disease relative to the other seed treatments. The highest yield (1896 kg ha-1) was recorded from Faruryo gele with Apron star and lowest (933 kg ha-1) was recorded from untreated Abadiro and Faruryo gele. So, Apron star was effective to reduce the yield loss of sorghum and could be recommended to manage sorghum covered kernel smut. However, the experiment should be repeated across different environments over years in order to give the right recommendations and its rate may need to be well defined.
