PEMBERIAN BERBAGAI KONSENTRASI AIR KELAPA PADA BIBIT KOPI ROBUSTA (Coffea canephora Pierre)
Abstract: This research aims
to determine the influence of the concentration of coconut water, to find out
the best concentration for the growth of seedlings of robusta coffee plant and
look for correlation of all parameters on the treatment that gives the highest
growth. This research has been carried out in the UPT area of research farm in
the faculty of agriculture, University of Riau.
This research was conducted in June to September. This design of this
research was completely random design, 5 treatments and 4 replications. Each
research unit consists of 3 plants, thus the number of sources used as many as
60 robusta coffee seeds.
The results showed that an increase in the concentration of coconut water
also improves the increment of plant height, the increase in the circumference
of the trunk, broad leaves, root header ratio and dry weight of the plant. The
results showed that an increase in the concentration of coconut water doesn't improve
the increment of the number of leaves. Treatment of the application of the
coconut water with a concentration of 50% gives the highest influence for the
increment of plant height, the increase in the circumference of the trunk,
broad leaves, root header ratio and dry weight of the robust coffee plant. The
plant's dry weight is correlated very strongly with the increment of the number
of leaves, broad leaves and root shoot ratio. Plant dry weight correlated
strongly with the increase in the circumference of the trunk and the increment
of plant height.
