Palm oil is potential to improve Indonesian economic, especially in Riau province because of land and climate suitability and the increasing demand of CPO. The purpose of this research was to find out the factors of palm oil supply in Riau Province and the effects of fluctuation of the factors. This research was conducted in Pekanbaru from Januari to September 2008. Research method was literature study using secondary data (1987-2006) which was analyzed by SAS 6.12 program. The factors of palm oil supply in Riau Province is the real price of CPO, real price of urea, palm oil plantation area, and productivity of palm oil. This research got F value of 2.283,68 for probability a=1%, R-square 0,9979 which show that the correlation between independent and dependent variable is strong. Adj R square of 0,9979 show that 99,79% of independent variable is explained by dependent variable but 0,21% is explained by other factors which are not included. Real price of CPO, palm oil plantation area and productivity of palm oil oil shows positive correlation effect with estimation of 2,10 (probability a=16%), 3,46 (probability a=1%), and 223.471 (probability a=1%). The real price of urea shows negative correlation effect with estimation of -52,62 (probability a=1%).

Identification of high inputs to increase the land suitability for oil palm plantation was carried out at PT. Teso Indah, Indragiri Hulu, Riau in 2006. The land evaluation system applied in this study was maximum limiting factors. The result of this study indicated that reas occupied by three soil mapping units were: SPT1 of 3,988.36, SPT2 of 807.57 and SPT3 of 21.07 ha. Actual land suitability classes of PT. Tweso Indah were not suitable currently and the limiting suitability factors are depth (100-200 cm), flood, drainage, pH, and base saturation. The high inputs needed to increase the suitability class are compacted peat and draiage channel construction.

The major problems found In uUlization of tidal swamp land for farmland is the abundmicc of water, low salinityami pi 1 and relatively low organic compounds. Tliese problems can be coped with the ameliorations. Based onthis fact, the experiment was carried out to evaluate the effect of variou.s doses of manure and dolomite in thegrowth and production of sweet com in the tidal swamp land. ThLs experiment has been conducted in the InsitVillage, Tebing Tinggi Barat Sub District Bengkalis Regency using a randomized factorial block experimentParameters observed were wet-weight and dry-weight of sweet com plant, emergence time of anther and stigma(days), length of corncob (cm), diamctcrofcomcob(cm), and number oflincof corncob .Experimental resultsshow that treatment of tidal swamp land with manures significantly influenced the wct-wcight of sweet cornplants, enuTgence time of stigma, and length of conicob. Addition of some dolomite to the tidal swamp land andinteraction between manures and dolomite did not significantly influence all parameters observed duringexperimental periods.

The purpose of research was to know the influence of organic manure and KCl to the growth and suitable/recommended dosage for the manure combination. This research was executed by factorial experiment (Randomized Complete Block Design) with two factors and three replications. The parameters controlled were height of plant, amount of corm, wet weight and dry weight. The result explained that interaction between organic manure and KCl significantly influenced amount of corm, wet weight and dry weight, but did not significantly influenced the plant height. Organic manure and 250 kg/ha KCl was the best treatment for all parameters.

Very low level of Phosphorus (P) availability in lowland area may cause serious hidrance on soybeanproduction in Riau. Addition of P fertilizer to the soil is significant for accelerating soybean production,however there were very limited farmers which were wiling to fertilize their soybean due to limitedcapital and unavailable cultivars that is efficient in absorbing P from soil particles. Therefore, it isimportant to investigate the efficiency of P fertilizer by soybean cultivars (Glycine nuv: L . Merril).This experiment are intended to identify soybean cultivars that are responsive to P-Fertilizer from dieobservation on the growth and production of soybean and to investigate the efficiency of P-Fertilizerby soybean cultivars. The experiment has been conducted in the Field Station of Faculty of Agricul-ture, Riau University located at Pekanbaru, Riau. The materials consisting of 5 cultivars of soybean, is: Kipas Putih, Malabar, Willis, Argoimtlyo and Bromo. Had been planted in plots applied by fourlevels of P fertilizer. The levels of P fertilizer were 20 kg, 40 kg, 60 kg PO per hectare and control.The experiment were arranged in a randomized factorial block experiment with three replications. Ingeneral, addition of fertillizcrdid not influence crop growth significantly especially on vegetative diyweight, the percentage of filled pods, individual seed weight, and P absorption efficiency.The cultivarsdiffered significantly in response to P fertilizer aplication. Optimum efficiency of seed production wasfound for Kipas Putih and Bromo at the level of 40 Kg PO per hectare while in other cultivars, theoptimal, was reached when they where not fertilized by P fertilizer. Optimum absorption of P fertilizerwere detected on Kipas Putih and Bromo at the level of 40 kg PO, per hectare, while in othercultivars the optimum absorption efficiency was obtained when crops were not fertilized.

ABSTRACTThis study aims to observe and obtain a better concentration of powder extract of wild betel leaf ability incontrolling anthracnose disease on red chili fruits.This study was performed experimentally using a completelyrandomized design consisting of 5 treatments and 4 replications thus obtained 20 trial units. The treatmentis the concentration of powder extract of wild betel leaf: KO= 0 g/l, K1= 25 g/l, K2= 50 g/l, K3= 75 g/l andK4= 100 g/l of water. The study consisted of two tests: in vitro inhibition of the fungus C. capsici and in vivoapplication of powder extract of wild betel leaf. The data were analyzed statistically using analysis ofvariance and the means were tested with Duncan ‘s New Multiple Range Test (DNMRT) at level 5%. Theresults showed that the concentration of powder extract of wild betel leaf significantly affected C. capsicigrowth and increase the percentage of fungal growth inhibition. Powder extract of wild betel leaf atconcentration of 100 g/ l of water quite capable the hold of anthracnose disease cause C. capsici, so as toreduce the intensity of attacks to 10% the effectiveness 52%.Key words: Red chili fruit, C. capsici, P. aduncum L.

The objective of the research was to determine the influence of dosage and storage ripening of Calcium Carbide in degreening process of Bangkinang citrus. The research was set up in Complete Randomized Design with four calcium carbide dosage (20, 25, 50, 75 g/kg) on three duration of storage ripening (3, 4, and 5 days). The result of this research concluded that the best treatment was the degreening process with 50 and 70 g/kg calcium carbide dosage and 4 to 5 days storage ripening. Physical and chemical analysis af citrus from this treatment resulted in 5,083-6,2500 Brik total soluble solid and 0,043-0,77% total acid, while organoleptic test showed average hedonic score of 5 and 4,8-5 (both were extremely like), for colour and flavor, respectively. Key words : Calcium carbide, degreening, citrus.
