Abstract

PB 260 atau dikenal dengan klon quick starter memiliki masa gugur daun lebih cepat dibandingkan dengan jenis klon lainnya. Pada penelitian ini bertujuan untuk menentukan hubungan antara perbedaan umur tanaman karet klon PB 260 dengan kadar kandungan sukrosa lateks yang dihasilkan. Penelitian ini dilakukan di PT. Perkebunan Nusantara III (Persero) Afdeling I, Bandar Betsy, Kabupaten Simalungun, pada ketinggian 900 m di atas permukaan laut. Tanaman yang diamati yaitu jenis klon PB 260 dengan waktu tahun tanam 2004, 2005, 2010 dan 2011 yang memiliki lingkar batang 60-75 cm dan dihitung dengan tinggi 130 cm di atas permukaan tanah. Metode penelitian ini ditentukan dari analisis uji korelasi dan regresi. Hasil penelitian diperoleh hubungan antara peran dari kandungan sukrosa terhadap produksi lateks klon PB 260 diperoleh waktu tahun tanam 2004 yang kecil hanya 3%, tahun tanam 2005 sebesar 14%, 2010 dan 2011 sangat kecil hanya 0,3%.

Abstract

This research was carried out at the PTPN III Sarang Giting plantation, Afdeling II, which is located in Sarang Giting Village, Dolok Masihul District, Serdang Bedagai Regency, North Sumatra Province. Venue Altitude 30m above sea level (asl) and flat land topography. The purpose of this study was to determine the effect of stem circumference and production of rubber plants (Hevea brasiliensis Muell. Arg) on ​​potassium (KCl) combined with agricultural lime (CaCO3) and magnesium (MgSO4) and their effect on the dynamics of soil K levels. This study used a factorial randomized block design (RBD) with 3 (three) factors studied, namely the agricultural lime application factor (C), which consisted of C0 = control and C1 = 1500g/tree/year. The second treatment factor was giving magnesium (M) which consisted of M0 = control, M1 = 1500g/tree/year, M2 = 3000g/tree/year, and M3 = 4500g/tree/year. The third treatment factor was the provision of potassium (K) consisting of K0 = control, K1 = 500g/tree/year, K2 = 1000g/tree/year, and K3 = 1500g/tree/year. The results showed that the administration of potassium combined with the application of agricultural lime and magnesium had a significant effect on the growth parameters of stem circumference. Potassium application combined with agricultural lime and kiserite also had a significant effect on the dynamics of K levels in the soil. However, it did not significantly affect the production of liquid latex
