APLIKASI DOSIS TRICHOKOMPOS JERAMI PADI PADA BIBIT KOPI ROBUSTA (Coffea canephora Pierre)
Abstract: Coffee is one of the
plantation commodities which have economic value and play an important role as
a source of foreign exchange. In order to improve the productivity it is
required good seedling. Attempts to
increase coffee productivity are selection varieties, plant maintenance and
appropiate fertilization. The use of organic fertilizer nutrients can
contribute also further role in the process of decomposition of the soil
organic matter. Organic fertilizer which can be used include paddy straw
Trichokompost. Paddy straw Trichokompost rice is easy to apply, does not
produce a poison (toxin), environmentally friendly and does not interfere with
other organisms that benefit for plants, especially organisms in the soil. This
study aims to determine the effect of various dosage paddy straw Trichokompost
in Robusta coffee seedlings and get an appropriate dosage for seedling growth
of Robusta coffee (Coffea canephora Pierre). The research was conducted at the
experimental field of the Faculty of Agriculture, University of Riau. This
research was carried out for three months starting from March to June 2015. The
study was conducted using a completely randomized design (CRD) with 5
treatments and 4 replications so that a total of 20 experiments units. Each
unit consisted of 3 seedling thus obtained 60 seedling. Treatments were 0, 25,
50.75 and 100 g/plant. Parameters measured were the increase seedling height
(cm), the number of leaves increase (pieces), addition girth (cm), leaf area
(cm2), dry weight (g) and the ratio of the root crown. Statistical analysis
using ANOVA and observation further analysis of significant variance with the
Least Significant Difference at 5%. Application of paddy straw Trichokompost 75
g / plant (15 tonnes / ha) and the application of paddy straw Trichokompost 100
g / plant (20 tonnes / ha) gives the best coffee seedling growth in all
parameters of robusta coffee seedling.
