This research aimed to learned the capability some of amelioran ratio and application natural PGR on the rice crop in peatlands to increased the growth and production and also pressed emision gas CO2 and CH4. This research has done in peatlands in Tanjung Air Hitam village, Pelalawan, from August 2012 until February 2013. This research has done experimentally used split plot design. The main plot was natural PGR from banana stump (Z1) and bamboo shoot (Z2). The subplot was amelioran ratio {dregs and compost of Oil Palm Empty Fruit Bunch (OPEFB)}, with 3 level treatment, there are 1:4 (dregs 1,25 ton/ha : 5 ton/ha OPEFB compost); 1:2 (dregs 2,5 ton/ha : 5 ton/ ha OPEFB compost) and 1:1 (dregs 5 ton/ ha : 5 ton/ ha OPEFB compost). In this research was got 6 combination with 3 replication. The result showed commonly application amelioran ratio 1:4 with PGR from banana stump inclined produced the result of maximum tillers, productive tillers, volume root, dry weight straw and the highest production and the highest emision gas CO2 and CH4, either vegetative and generative phase. The lowest emision gas CO2 and CH4 were in application 1:1 amelioran ratio with PGR from bamboo shoot, either vegetative and generative phase.
