The study was conducted with the objectives to introduce adaptive, high grain and forage yielder of improved Oat accessions/varieties for mid land of Guji zone, Oromia, Ethiopia. The experiment was conducted in Randomized Complete Block Design (RCBD) with three replications under Bore Agricultural Research Center, Adola sub site for two consecutive (2013/14 to 2014/15) in the mean season. Data of 50% date flowering, date of mature, biomass yield, plant height and diseases incidence were collected. Significant (P<0.001) differences were observed for all measured agronomic traits except for lodging and green fodder yield. The result indicates that Jasari was the shortest and Grayaleris was the longest in terms of date of 50% flowering. Grayaleris Variety is late mature whereas Bona Bas variety is early mature. The maximum and minimum plant height was recorded from Lampton and Grayaleris variety respectively that showed significant (P<0.001) variation. Jasari variety (90%) followed by 6710 (83.33%) accession and lampton (78.33%) variety was the most susceptible and has low resistance to disease reaction (leaf and stem rust) and the lowest diseases severity was recorded from Bona Bas (1.67%) followed by Bonsa (6.6%) and 79Ab382 (TX) 80SA95 (10%) varieties. The maximum grain yield (28.85 quant/ha) was produced by accession 79Ab382 (TX) 80SA95 followed by accessions CI-8235 and CI-8237 which where (26.48 and 26.43 quant/ha) respectively and Lampton variety produced minimum grain yield (15.36 quant/ha). From this study, it is concluded that the oat varieties/ accessions 79Ab382 (TX) 80SA95, CI-8235 and Bonsa were found a promising in terms of grain yield, green fodder yield, absence of lodge and diseases resistance than others that could be demonstrated and popularized as an alternative feed resources under smallholder conditions in the study areas and other places of Guji zones of Oromia region with similar climatic and edaphic conditions.
The shortage of arable land and shortage of livestock feed specially quality feed resources are major constraints in East Hararghe Zone. Thus, a field study was conducted to evaluate an early maturing sorghum varieties and cowpea Lines intercropping for both food and feed production at Fedis Agricultural Research Center, eastern Ethiopia in 2018/19 cropping season. Two cowpea varieties (lines) (9333 and 9334) were intercropped with three varieties of early maturing sorghum (Teshale, Birhan and Melkam) and compared with sole cropping of all the varieties, which were laid out in a randomized complete block design with three replications. The analyzed result showed the NDF content was significantly different (p < 0.05) among intercropped and sole sorghum the maximum NDF was recorded from sole sorghum Teshale (69.56%) and the minimum sorghum Birhan + cowpea (9333) (57.75%) and the Intercropping sorghum improved the CP of sorghum stover mean from sole (5.31%) to intercropped (6.03%). the. Cropping systems and cowpea lines were significantly affected (p < 0.05) the content of CP and NDF. The maximum CP obtained from cowpea (9334) + sorghum Teshale 29.19%), and the minimum CP obtained from sole cowpea (9333) (24.38%). Generally, the results of this study showed that intercropping of sorghum-cowpea were increased nutritional quality of cowpea and sorghum stover. Based on the results of this study, it concluded that intercropping sorghum with forage cowpea; preferably sorghum Melkam + cowpea (9333) to be appropriate to increase quality of sorghum stover in the study area.
