The study aimed at investigating and documenting indigenous knowledge （IK） on forage/fodder plant species and threats to their survival. Ninety-six in= formants between 20 and 80 years old were selected using prior informa- tion. Data were collected using semi-structured interview, guided field wail discussion and field observation. Preference ranking, Jaccard＇s coefficient of similarity and priority ranking were used for data analysis. One hundred twenty-six forage/fodder species of 90 genera and 43 fami- lies were collected in the study area. More than 88% of the species were reported with their vernacular names, where 68% were reported by the Afar Nation and 70% by the Oromo Nation. Family Poaceae was repre- sented by 25 species （20%）, followed by Fabaceae 18 （14%）. Preference ranking for the most preferred forage grasses as perceived by key informants revealed that Chrysopogon plumulosus was the most important forage/fodder species. Overgrazing was the major threat in the study area, scoring 22%.展开更多

Eight forage species, Lolium multiflorum L., Brachiaria decumbens, Digitaria sumtisii, Melinis minutiflora, Paspalum dilatatum, Paspalum wettsteinii,Sataria viridis Beanv and Shcep’s Festuca, were highly tolerant to acid soils, and grew relatively well in the tested soils without lime application, whereas most of the other 20 tested forage species such as Lolium perenne L., Meadow Festuca and Trifolium pratense L. were intolerant to acid soils, showing retarded growth when the soil pH was below 5.5 and significant increase in dry matter yields by phosphrus fertilizer application at soil pH 6.0. Results showed that large differences in tolerance to acid soils existed among the forage species,and tolerance of the forage species to acid soils might be closely associated with their tolerance to Al and P efficiency.展开更多
