Ten cultivars of Lablab purpureus selected from the previous preliminary variety trail were evaluated at two locations (Bako Agricultural Research Center and Billo Boshe sub-sites) located in the western part of Oromia regional states, Ethiopia during the 2012-2014 cropping seasons. The genotypes were evaluated in randomized complete block design in three replications for herbage dry matter (DM) yield and nutritional quality traits. The study revealed that, with the exception of cultivar and location interaction, herbage DM and crude protein (CP) yield were significantly (P<0.05) affected by cultivar, location, year and their interaction. Significantly higher herbage DM and CP yield was recorded for cultivars L. purpureus ILRI 14417 and L. purpureus ILRI 14455 as compared to the rest cultivars tested. The study also revealed that, the maximum herbage DM and CP yield was produced more at Bako compared to Billo Boshe sites. Moreover, herbage DM and CP yield were also recorded higher during the second production year and followed by year 3>year 1, respectively. With the exception of CP value which significantly (P<0.05) varied among the cultivars, no significant (P>0.05) differences were observed in the remaining fiber and no-fiber quality traits assessed in the study. The higher CP value was recorded by L. purpureus ILRI 14417 (264.6 g/kg DM) and L. purpureus ILRI 14455 (248.6 g/kg DM). Generally, L. purpureus ILRI 14417 and L. purpureus ILRI 14455 cultivars exhibited constantly superior herbage DM yield and nutritional value as compared to the remaining cultivars indicating their potential to be recommended as alternative quality feed resources in the western part of Oromia, Ethiopia.
