Pengaruh Frekuensi Pengendalian Gulma Secara Manual Terhadap Pertumbuhan dan Produksi Padi Sawah (Oryza Sativa L.) Dengan Metode Sri
Abstract: The objective of
this research was to find the effect of frequency by manually weeds control for
growth and the production of paddy field (Oryza sativa L.) by SRI methode. This
research was conducted in Balai Benih Induk Hortikultura at Kaharuddin Nasution
street, Padang Marpoyan, Pekanbaru. This research held for 5 months, started in
November 2011 until March 2012. This research use Randomized Block Design (RBD)
that consists of 4 treatments and 3 replications. These treatments consist of
once weeding ( 30 days after planted), twice weeding ( 20, 40 days after
planted), third weeding (20, 30, 40 days after planted) and fourth weeding (
10, 20, 30, 40 days after planted) manually. Parameters measured were plant
height (cm), number of maximum nhymps (stem), the outgoing panicles (days), the
number of productive tillers (seed), dried milled rice production per clump
(g), 1000 seed weight (g). Data was analyzed by analysis of variance and
further test by Duncan Multiple Range Test (DNMRT) at the level of 5%. The research showed that the treatment of
frequency by manually weed control were
not significant to all parameters (parameters measured were plant high, number
of maximum nhymps, the outgoing panicles, the number of productive tillers,
1000 seed weight ) except in parameter of dried milled rice production per
clump and the manually weeding of once frequency (30 days after planted) has yield 15,2 t/ha.
