Diversity of availability of feed plant on sub optimal land in Karangasem Regency, Bali

The development of forage crops in Indonesia is directed at lands that are less productive for food crops, marginal land, and critical land, known as sub-optimal land. The research was carried out in Karangasem Regency: West Seraya, Seraya, and East Seraya Village which are Karangasem District, and Dukuh, Sukadana, and Tianyar Village, which are Kubu District. The number of respondents involved in this study were 20 farmers in each village, so the total number were 120 people. The data obtained were presented and analyzed descriptively. From the observations, it was found that the botanical composition of native pasture for the Seraya location found the presence of Panicum maximum grass that spreads on farmers' arable land and rudera areas. The types of shrub legumes used as hedgerows are Gliricidia sepium, Leucaena leucocephala, and Calliandra calothyrsus. The proportion of feed availability of shrub legumes, especially on hedgerows, is dominated by G. sepium. It can be concluded that the diversity of forage on sub optimal land is a potential in efforts to provide and fulfill bali cattle feed throughout the year, and the development of bali cattle and the availability of forage is dominated by shrub legumes, especially G. sepium and tree species
