摘要：This study was conducted to analyze the botanical composition, grass production, carrying capacity, and potential production of nutrients in pasture located in Timor Tengah Selatan Regency. The experiment was conducted from February to July 2013, using field survey method. The botanical composition, grass production and carrying capacity on real condition were analyzed descriptively, while the grass production and carrying capacity based of cutting arrangement were analyzed by using randomized block factorial design with 3 altitude locations (Sub District of Mollo Utara with altitude of 1007 m above sea level; Sub District of Noebeba, 500 m ASL, and Sub District of Amanuban Selatan, 65 m ASL) x 2 cutting intervals (1 and 2 month) and 5 replications. The results showed that the grass type dominated the pasture in the Sub District of Mollo Utara, while legum type was more dominant in the pasture in the Sub Districts of Noebeba and Amanuban Selatan. The potential production of dry matter grass in Timor Tengah Selatan Regency based on real condition was 150 to 390 kg/ha/yr, this could accommodate 0.24 to 0.63 AU/ha/yr. The arrangement of cutting interval by 1 month in Mollo Utara and 2 months in Noebeba and Amanuban Selatan could increase (P<0.05) grass production and carrying capacity. The potential productions of grass nutrients were higher in Sub District of Mollo Utara, while potential production of grass dry matter was higher in Sub Districts of Noebeba and Amanuban Selatan. It was concluded that grass dry matter potential production and carrying capacity in Timor Tengah Selatan Regency were low. The arrangement of cutting interval could increase grass dry matter potential production, carrying capacity, nutrition production, and quality of nutrition.
其他摘要：Penelitian ini bertujuan untuk menganalisis komposisi botani, produksi rumput, kapasitas tampung dan produksi nutrisi rumput pada padang penggembalaan di Kabupaten Timor Tengah Selatan. Penelitian dilaksanakan bulan Februari sampai Juli 2013, menggunakan metode survei lapang. Variabel komposisi botani, potensi produksi bahan kering rumput, dan kapasitas tampung pada kondisi riil, serta potensi produksi nutrisi rumput dianalisis secara deskriptif, sedangkan produksi rumput dan kapasitas tampung berdasarkan pengaturan pemotongan dianalisis menggunakan rancangan acak kelompok pola faktorial, yaitu 3 lokasi dengan ketinggian berbeda x 2 interval pemotongan dengan 5 ulangan. Hasil menunjukkan bahwa rumput mendominasi padang penggembalaan di Kecamatan Mollo Utara, sedangkan leguminosa mendominasi padang penggembalaan di Kecamatan Noebeba dan Amanuban Selatan. Produksi rumput pada kondisi riil di Kabupaten Timor Tengah Selatan sebanyak 150-390 kg/ha/thn dapat menampung 0,24-0,63 ST/ha/thn. Pengaturan pemotongan dengan interval pemotongan 1 bulan di Kecamatan Mollo Utara, 2 bulan di Kecamatan Noebeba dan Amanuban Selatan dapat meningkatkan (P<0,05) produksi rumput dan kapasitas tampung. Potensi produksi nutrisi rumput tertinggi terdapat di Kecamatan Mollo Utara, sedangkan potensi produksi bahan kering rumput tertinggi di Kecamatan Noebeba dan Amanuban Selatan. Disimpulkan bahwa produksi rumput dan kapasitas tampung di Timur tengah Selatan adalah rendah. Kondisi pengaturan pemotongan dapat meningkatkan produksi, kapasitas tampung, dan kualitas nutrisi rumput.
