PERTUMBUHAN DUA KLON KARET ASAL BIBIT OKULASI DI KABUPATEN BANYUASIN, PROVINSI SUMATERA SELATAN (Growth Performance of Two Rubber Budding Clones in Banyuasin District, South Sumatera Province)

Rubber clones have different adaptability which leads to no rubber clone being superior for all planting locations. Therefore, the agro-climatic characteristics of plantation area are needed determine suitability class land before extensive is carried out. The aim this study was examine growth combination (IRR 112 and IRR 118) number umbrella leaves (two umbrellas three umbrellas) during immature plants (TBM). Plantation established at Experimental Garden Research Center, Banyuasin Regency, South Sumatra Province. Land determined based on soil data climate data. Clone observed stems from a sampling 500 trees each clone-umbrella combination. Growth measurement out every year until five years old plants. results showed that with best material reach 81% mature tapping after old. It recommended can be planted suitable (S2) in lowlands Ultisol type. Keywords: Clone, seeds, suitability, circumference stem ABSTRAK Klon tanaman karet memiliki daya adaptasi yang berbeda-beda, sehingga tidak ada klon unggul di semua lokasi penanaman. Oleh karena itu karakteristik agroklimat pada areal penanaman diperlukan untuk menentukan kelas kesesuaian lahannya sebelum secara luas dilaksanakan. Penelitian bertujuan menguji pertumbuhan kombinasi dan jumlah payung daun bibit (payung dua tiga) selama masa belum menghasilkan Penanaman dilakukan Kebun Percobaan Pusat Karet, Kabupaten Banyuasin, Provinsi Sumatera Selatan. Penentuan lahan berdasarkan tanah iklim. Pertumbuhan diamati pengukuran lilit batang pohon setiap klon-jumlah payung. Pengukuran tahun sampai dengan umur lima tahun. Hasil penelitian menunjukkan bahwa tiga merupakan terbaik telah matang sadap. Bibit tersebut dianjurkan ditanam sesuai dataran rendah jenis Ultisol. Kata kunci: Klon, karet, lahan,
