Abstract

Slow and quick starter clones were used for long-term productivity stability on rubber plantation. Each clone has different characteristics. Therefore, it is necessary to conduct research on exploitation system according to Oldeman climate type in order to increase the latex productivity. The research was conducted in two locations, namely Sungai Putih Experimental Farm, Rubber Research Centre and Sungai Putih Farm, PT. Perkebunan Nusantara III (Persero). Both locations are located in District of Galang, Regency of Deli Serdang on 25 m above sea level with Ultisol soil type. Rubber tree material are planting in the year of 1999, with spacing of 2.5m x 5m, clones representing Quick starter K1 (PB 260) and Slow starter K2 (BPM1). This research uses primary and secondary data. Primary data is field experiment using Nested Design. Secondary data was obtained from PTPN III Sungai Putih that has the average of monthly rainfall data for 13 years (2002 - 2015). Tapping system was consisted of 2 treatments namely half-spiral downward tapping system (S/2) and upward tapping system (S/2U). The treatments consisted of two levels: P1: ethepon 2.5% applied once for 15 days (ET / 15d), P2: gas stimulant applied once and once for 27 days (ETG 27d). Every treatment used 75 trees with girth 65 cm - 70 cm. The results showed that based on Oldeman climate type, tapping system S/2U d3 ET/15d is suitable for clone BPM 1 and S/2 d3 ET/15d for clone PB 260.
