    The research aims to determine the effect of addition ameliorant dregs to the empty bunched of oil palm compost (EBOPC) and natural plant growth regulation for rice growth and production on peatland. The research was conducted on Tanjung Air Hitam village, Kerumutan, Pelalawan-Riau from August 2012–February 2013. The research was arranged in split plot design as environmently design and completely randomized design as the experimentally design. The main plot was consist with 3 levels of plant growth regulation extract of Z1 (banana stump), Z2(bamboo shoots), and Z3 (mixture of both).The subplots were dosage of ameliorant dregs consists of 3 levels F1 (1.25tonnes), F2 (2.5tonnes)and F3 (5tonnes)perhectare. The results showed that the addition of 1.25 tonnes of ameliorant dregs per hectare combined with banana stump tends has tend to increaseof plant height, number of maximum tillers, number of productive tillers, percentage of pithygrain, thousand grain weight and increase pithydry milled grain weight perhectare.

    Pengaruh Pupuk Anorganik Pada Tanah Gambut Terhadap Produksi Cabai Merah (Capsicum annum L)

    Chili is a horticultural crop that is in demand by most of the people of Indonesia, is widely used for household and industry so that the chili demand continues to increase every year. Parallel to the decreasing availability of arable land, the expansion of the agricultural area is directed to the peat, as peat soil organic matter content is high enough (Suryadinata, 2009). Many organic materials containing cellulose decomposed difficult. Additionally peat soil fertility is low, which is classified as very acidic soil pH (4.3) with N-total (0.04%) and KB (7.13%) is very low, while the CEC (38 me/100g) is high. Elements of P in the soil is around the criteria were (23.63 me/100g) and low K elements (0.231 me/100g) (Suryadinata, 2009). From the results of the study shows that inorganic fertilizers on peat soil on the production of red chili significant effect on all the parameters the observation
