PENGARUH PEMBERIAN BEBERAPA JENIS EKSTRAK TANAMAN SEBAGAI ZPT DAN RASIO AMELIORAN TERHADAP PERTUMBUHAN DAN PRODUKSI PADI VARIETAS INPARI 12 DI LAHAN GAMBUT
ABSTRACT: This research aimed
to get the kind of plant extracts as a Plant Growth Regulator (PGR) exogenously
given and ameliorant ratio that influential as improving rice growth and
production in peatlands. This research had been done in peatlands at Tanjung
Air Hitam Village, Pelalawan, started from August 2012 until march 2013. This
research had been done experimentally using split plot design. The main plot
was the plant extract from banana stump (Z1), bamboo shoot (Z2) and the mixture
(Z3). The subplots were ameliorant ratio (compost of Oil Palm Empty Fruit Bunch
(OPEFB) and dregs}, with three level treatment, that were 4 : 1 {OPEFB compost
5 ton/ha + dregs 1,25 ton/ha), 2 : 1 (OPEFB compost 5 ton/ha + dregs 2,5
ton/ha) and 1 : 1 (OPEFB compost 5 ton/ha + dregs 5 ton/ha). In this research
was got 9 combinations with 3 replications. The result showed that giving of
plant extracts and ameliorant ratio was nonsignificant for the plant height,
maximum tillers, productive tillers, age of harvest, grain per panicle, grain
pithy percentage, weight of 1000 grains and also rice production per plot.
