PENGARUH TANAMAN SELA SORGUM MANIS TERHADAP PERTUMBUHAN TANAMAN KARET BELUM MENGHASILKAN
Abstract: The Land between row
of immature rubber period has a potential to produce sweet sorghum. This
sorghum is one of high value commodities for food and energy security due to
its wide adaptation. The objective of this research were to study the effect of
rubber+sorghum intercropping system on the growth of immature rubber trees and
to study some agronomic parameters of sorghum and production of sweet sorghum
as rubber intercrops. The experiment was conducted at the Sembawa Research
Station from June to October 2013. The experiment was carried out as a single
factori using Randomized Block Design with three replications. The treatment
were 3 varieties of sorghum i.e: Pahat, Kawali and Mandau. Observation of
rubber trees was conducted using simple random sampling method, comparing the
rubber trees growth of sorghum intercropping system with the rubber trees
growth of monoculture system. The results showed that sorghum had a positive
effect on the growth of rubber tree IRR 118. Furthermore, fresh stem weight
(37.11 t/ha), juice yield (1.80 t/ha), and grains yield (2.69 t/ha) of sweet
sorghum Kawali higher than that of the varieties tested. The Kawali has a high
potential to produce a biofuel because it had a highest fresh stem weight and
juice content.
