Assessment of commelina species feed use in Konso Zone, Southern Ethiopia: Identification, seasonal characterization, and altitudinal distribution

Abstract

Searching for low-cost, readily available non-conventional feeds is viewed as an alternate measure and solution in resolving feed-related difficulties. This study was conducted to investigate Commelina species feed use in Konso zone, Southern Ethiopia, by identifying available species and characterize seasonal and altitudinal distribution. The data were gathered through focus group discussions and interviews with 195 households drawn randomly from 15 villages. Five Commelina spp.; Commelina benghalensis, Commelina imberbis, Commelina diffusa, Commelina albescens, and Commelina africana were identified in the study area. C. diffusa was available year-round (88.71%) at low and mid altitudes, whereas all others show diminishing pattern with dry season. C. benghalensis, C. imberbis and C. diffusa were found in low and mid altitudes, whereas C. africana and C. albescence were found only in low altitude. Availability and distribution of commelina spp. in the study area shows variability with seasonal and altitudinal changes. The wider feed usage by livestock keepers across all the corners of the area, combined with the species’ proclivity to grow as friendly alley crops on farmland, suggests that the value of C. benghalensis and C. imberbis may extend beyond feed use. Agricultural experts must transfer intercropping trend of C. benghalensis, and C. imberbis with food crops to farmers who lack it. Nutritional quality of the species should be conducted to have a clear picture about feed value of the plants.
