PERTUMBUHAN DAN PRODUKSI PADI GOGO (Oryza sativa L. ) MELALUI APLIKASI BEBERAPA DOSIS ABU SEKAM PADI DAN PERBEDAAN KOMPOSISI PUPUK DI LAHAN GAMBUT
Abstract: This research was
aimed to determine the effect of husk
ash of rice and composition of fertilizer and its combination to increase
growth and production of field rice and determine the best treatment dose of
growth and production of field rice in peatland. The research was conducted at
the experimental farm of the Agricultural Faculty University of Riau, Rimbo
Panjang, Kampar from July to December 2016. The design used in this research
are arranged in a Factorial Completely Randomized Block Design (RBD) consiting
of two factor with three replication. The first factor are: Aplication of husk
ash of rice (S), namely: S1 (2,5 tons/ha), S2 (5 tons/ha), S3 (7,5 tons/ha). and
the second factor are: Composition of fertilizer, namely: K1 (Fertilizer Urea
200 kg/ha, TSP 100 kg/ha, KC 100 kg/ha), K2 (Fertilizer Urea 100 kg/ha TSP, 50
kg/ha, KCl 50 kg/ha) with coffee-based compost with chicken manure (3:1), K3
(Fertilizer Urea 100 kg/ha TSP, 50 kg/ha, KCl 50 kg/ha with coffee-based
Compost with chicken manure (1:1), and K 4 (Fertilizer Urea 100 kg/ha TSP, 50
kg/ha, KCl 50 kg/ha) with coffee-based with chicken manure (3:1). The data
obtained by analysis of variance (ANOVA) was tested further by Duncan’s New
Multiple Range Test (DNMRT) at the level of 5%. The results showed that the
combination treatment of rice husk ash 5 ton / ha and the composition of the
fertilizer Urea, TSP, KCl (100,50,50 kg / ha) with with coffee-based compost with
chicken manure (1: 1) showed better influence for maximum number of tiller,
number of panicle / clump, number of grain per panicle, 1000 grain weight and
dry weight of 344.52 g / m2 (3.34 ton / ha). The best rice husk ash treatment
for upland rice plants is ash rice husk dose 7.5 tons / ha. The best
composition of fertilizer and coffee-based compost for the upland rice plant is
the composition of fertilizer Urea, TSP, KCl (100,50,50) kg / ha with
coffee-based compost with chicken manure (1: 1)
