DINAMIKA SISTEM BERBAGI SUMBERDAYA (RESOUCES SHARING) DALAM AGROFORESTRI: DASAR PERTIMBANGAN PENYUSUNAN STRATEGI SILVIKULTUR
ABSTRACT: The determining
factor of resources dynamics in agroforestry systems is component
characteristics of its composer. This dynamics influencing the resources sharing
systems among the composers. This research has objects to understand the dynamic
of resources sharing system and the
arrangement of productivity improvement strategy in agroforestry
systems.
The research was approached through the expression of crops (corn) in responding
the resources within trees along border and alley cropping patterns. Data was
analyzed by using general linear model based on split plot to analyze dry
weight, leaf
area, chlorophyll content and leaf greenness. Where as the nutrients
contended by tissues was analyzed by using RCBD. If there is difference among
the mean of experiments there will be next step which is Duncan Test to find
out the best response in significant level of 5%.
The result showed that the absorbance
and exploitation based on the highest energy level in succession was
zone 3, 2 and 1. Nutrients status and water level in zone 1, 2 and 3 gave no
significant, where as there was difference of rooting systems in each zone which
were root weight in depth 10-20 cm, root length in 0-10-20 cm depts. and root surface
area in 0-10, 20-30 cm depth. Resources sharing system in zone 1 (dominated by suppressed
trees and crops), zone 2 (suppressed
crops) and zone 3 (dominated crops).
The light capture scenario from zone 1 to zone 2 or from zone 2 to zone 3
through crown pruning whereas it’s light capture scenario from zone 1 to zone 3
can be carried out through pollarding and commercial thinning. The underground scenario can be carried out
through root pruning trees component within the distance of 2 meter from trees
line and 30 cm of minimal depth.
Key words: agroforestry,
resources sharing, silviculture scenario
