    The research aimed to study the effect of sawdust ash and manure P content Guano on plant growth, yield components of upland rice, and get the proper dosage. The experiment was conducted at the experimental farm of the Agriculture Faculty, Rimbo Panjang, Kampar and carried out in September until February 2012. Research conducted experiments using Randomized Block Design (RBD) 4 x 3 factorial. The first factor is sawdust ash (A), which consists of 4 standard, namely, A0 (without sawdust), A1 : 1.5 kg/plot (5 tons/ha), A2 : 2.25 kg/plot (7,5 tons/ha), A3 : 3 kg/plot (10 tons/ha). The second factor is the Guano Fertilizer (G) consisting of: G0 (without Guano Fertilizer), G1 : 90 gram (300 kg/ha), G2 : 180 grams (600 kg/ha). The results obtained by analysis of variance test was tested further by Duncan's New Multiple Range Test (DNMRT) at the level of 5%. From the research it can be concluded from some ASG and fertilizer dose level Guano looks combined ASG 3 kg/plot and 180 g/plot Guano gives the highest yield average on most parameters. Dose ASG 2.25 kg/plot with Guano 180 g/plot did not differ significantly with the combination of ASG 3 kg/plot and fertilizer Guano 180 g/plot at all parameters.

    Upland rice cultivation has many obstacles, because the dry land is generally nutrient-poor, high acidity levels, and poor organic matter. To help the absorption of nutrients can be done by using organic materials as fertilizer. Organic fertilizers can be used is composted oil palm empty fruit bunches (TKKS) and green manure LCC. This research has been conducted on the experimental farm of Faculty of Agriculture, University of Riau in May to October 2012. The research was conducted using a randomized block design experiment (RAK) non-factorial. The number of combinations is 12 combinations with each treatment was repeated 3 times to obtain 36 units of the experiment. Each of these 35 plots planted clumps. Data were collected for five clumps of samples taken at random in each experimental plot. The data obtained were statistically analyzed using analysis of variance (ANOVA) and ANOVA results further tested by the test of Duncan's New Multiple Range Test (DNMRT) at the level of 5%. Giving TKKS compost 5 tons / ha + 5 tons / ha LCC significant effect on the formation of the maximum number of tillers and dry weight gabah/m2. Compost TKKS 10 tons / ha without LCC can increase soil organic matter are influential in increasing plant height and weight of upland rice straw.

    Pengaruh Penggunaan Pupuk Kascing Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis jacq.) Dari Berbagai Sumber Asal Bibit di Pembibitan Utama

    This research aimed to determine the response of the growth of oil palm seedlings of different origin sources vermicompost fertilizer the main nursery. This research has done in plant’s laboratory field agriculture faculty University of Riau from March until July 2012. This research used completely randomized factorial design with two treatment factors and three replications. The first factor was source of the seed with three levels: S1= Asian Agri’s oil palm seed, S2= PPKS Medan’s oil palm seed, S3= Dami Mas’s oil palm seed. The second factor was vermicompost with four levels: K0= 0 g/ polybag, K1= 20 g/ polybag, K2= 40 g/ polybag, K3= 60 g/ polybag. The result showed that source of the seed significantly affect plant height increment parameter, root volume, seedling dry weight and seed quality index but non significant on accretion of leaves, stump diameter increment and ratio of the root crown. Vermicompost significantly affect plant height increment, accretion of leaves, stump diameter increment and seedling dry weight but non significant on root volume, ratio of the root crown and seed quality index. Interaction between the two treatments was non significant for all parameters.
