Abstract

Penyadapan yang tidak benar akan menghasilkan kulit pulihan yang buruk dan rendah produksinya. Beberapa alternatif sistem sadap perlu diteliti antara lain aplikasi stimulan, sistem sadap ganda, dan irisan sadap pendek.  Tujuan penelitian ini adalah untuk mengetahui pengaruh beberapa alternatif sistem sadap terhadap karakter fisiologi, pertumbuhan, dan produksi klon BPM 24. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Sembawa, menggunakan klon BPM 24, dan rancangan acak kelompok dengan 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa irisan ganda (S/4 U d3 ET2.5% Ga1 9/y (m) + S/2 d3 dan S/4 U d3 ET 2.5% Ga1 9/y (m) + S/4 d3 ET2.5% 9/y (m)) tidak mampu meningkatkan produksi dibanding sistem konvensional (S/2 d3). Kombinasi antara irisan pendek dan stimulasi justru menurunkan produksi karet kering. Irisan ganda menurunkan kadar karet kering (KKK) dan pertumbuhan lilit batang.
