Pengaruh Pemberian Zpt Alami Dan Beberapa Rasio Amelioran Pada Tanaman Padi Inpari 12 Di Lahan Gambut Terhadap Emisi Co2, Ch4 Dan Produksi
The aims of research to study the effect of application several ratio of ameliorant (dregs and Oil Palm Empty Fruit Bunch (OPEFB) compost) and natural Plant Growth Regulator (PGR) on rice production and gas emission of CO2 and CH4 in peatlands. This research was conducted on Tanjung Air Hitam village, Kerumutan, Pelalawan-Riau from August 2012 until January 2013. The easy conducted in field, this research has done experimentally used split plot design. The main plot was natural PGR from banana stump (Z1) and bamboo shoot (Z2). The sub plot was ameliorant ratio (dregs and OPEFB compost), with 3 level treatment, there are 1:4 (1,25 ton dregs/ha : 5 ton OPEFB compost/ha); 1:2 (2,5 ton dregs/ha : 5 ton OPEFB compost/ha); and 1:1 (5 ton dregs/ha: 5 ton OPEFB compost/ha). In this research was got 6 combination with 3 replication. The results showed that application ameliorant with ratio dregs : OPEFB compost 1:4 (1,25 ton dregs/ha : 5 ton OPEFB compost/ha) and PGR of banana stump produced the maximum tillers, volume root, and the highest rice production than the others treatment. But the lowest emition of CO2 dan CH4 on treatment 1:4 than the others treatment.
Keywords : Ameliorant, peatlands, rice, natural PGR, emision gas CO2 and CH4.
