Peatland is an important natural resource for human life because it can be used as growth of oil palm plantation. The growth of oil palm plantations in peatlands is strongly influenced by peat water management. This study aims to study the relationship of different water levels to the content of leaf Cu and Zn nutrients and the growth of oil palm plants (Elaeis guineensis Jacq.) in the peatlands. This research has been carried out on peatland areas in oil palm plantations of PT. Jatimjaya Perkasa Sei Bangko, Kubu District, Rokan Hilir Regency, Riau Province. Analysis of soil samples and plants samples has been carried out at the Soil Laboratory, Faculty of Agriculture, Universitas Riau, Pekanbaru. The research was conducted in December 2017 to January 2018. This research was conducted using a survey method, the determination of the location of the study using a purposive sampling method, determination of sampling location is determined by stratified sampling method, where the strata in this study are grouped according to different peat water levels namely water level < 40 cm , 40 - 60 cm, and > 60 cm with oil palm plants at the same age which is six years and the piezometer has been installed properly. The parameters that observed in this study were soil pH, availability of Cu and Zn nutrient, total soil-K, content of Cu, Zn and K leaves and growth of oil palm plants which included plant height, midrib length and leaflet. The observed data were analyzed for variance and tested further by DNMRT at the level of 5%, analyzed by regression to see the relationship between water level and parameters. The results showed that peatland with water level of 40 - 60 cm had a soil pH, K-total soil, Cu leaves, Zn leaves, midrib length and the highest oil palm plantations compared to peat land with a groundwater level < 40 cm and > 60 cm, and has a different length of leaflets.Key words : Cu and Zn nutrient, Oil palm plantation, Peatlands, Water Level.

This study aims to determine the types and ways of application of organic matter and the combination of both of the rice yields in peat growing media. This research has been carried out in the Experimental Garden of the Faculty of Agric ulture, Riau University, Campus Bina Widya Km 12.5, Simpang Baru Panam Sub-District, Tampan District, Pekanbaru, Riau. This research was carried out for 4 months, starting from May to August 2018. The research was conducted experimentally arranged according to a completely randomized design (CRD) factorial pattern consisting of 2 factors. Factor I: organic matter of plant waste (O), namely: O1 (125 g rice straw), O2 (125 g soybean litter), O3 (oil palm empty fruit bunches 125 g) and Fact II: how to apply organic material (C), namely: C1 (mixed) and C2 (spread). The results obtained were analyzed using variance analysis and continued with the double range duncan's new multiple range test (DNMRT) at 5% level. However, the type of organic rice paddy yields results in the weight of the milled dry grain which is 106.94 g-138.23 g, the weight of 1,000 grains that is 26.40 g-26.95 g and soybean litter on the percentage of rice grain grain 86.24 g-88.00 g. Giving application method in the distribution gives results on the weight of dry milled unhulled rice that is 125.21 g-126.02 g, the weight of 1,000 grains that is 26.65 g-26.79 g and the percentage of unhulled grain that is 86.76 g-87 , 74 g and the combination of the type of organic rice paddy and the application method in the distribution gives the results of the weight of the milled dry rice which is 102.94 g - 140.87 g, the weight of 1,000 items, which is between 26.29 g - 27.27 g and soybean litter organic material types and application method are mixed namely 84.94 g - 88.50 g.Key words : application method, rice plant, rice straw, soybean litter, TKKS.
