PENGATURAN POLA TANAM KARET (HEVEA BRASILIENSIS MUELL.ARG.) UNTUK TUMPANG SARI JANGKA PANJANG
ABSTRACT: Low prices of rubber
have been a serious problem to rubber farmers. The rubber based intercropping
system offers a practical solution to this issue and increasing overall
productivity. This experiment was aimed to determine the suitable spatial
arrangements in rubber planting to facilitate long-term rubber-based
intercropping systems. A field experiment was established in a smallholder
rubber plantation in the Tanah Laut District, South Kalimantan Province with an
area of 700 ha and Musirawas District, South Sumatra Province with an area of
400 ha. The experiment using two planting patterns of rubber clone PB260: (1)
single row planting pattern (SR) by 6 x 3 m, and (2) double row planting
pattern (DR) by (18 + 2 m) x 2.5 m. The experiment showed that the girth of
rubber trees in the SR system at the first tapping year was slightly bigger
than that in the DR system, however, it was not statistically significant. The
latex yield per tree of SR system was the same as the DR system, however latex
yield per hectare of SR system has higher than the DR system, because the SR
system have more population than the DR system. The DR system was proved to be
a suitable planting system for long-term rubber based intercropping systems.
