Abstract

The Research aims to study the effect of application of composting of oil palm empty fruit  bunch ( compost of OPEFB) and fertilizer of N, P and K to the growth and yield of sweet corn in Ultisol. The research conducted at Kampar District, Riau Province from September to December 2011. This reseach used completely randomized design (CRD)  consisting of 10 treatment; 0, 20, 40 and 60gram OPEFB compost/polybag (A,B,C and D); 20, 40, and 60gram/polybag OPEFB compost/polybag +fertilizer of N,P, K with half the recommended dose (E,F and G); 20, 40, and 60gram OPEFB compost + fertilizer of N,P and K with recommended dosage ( H,I and J)  each treatment was repeatet 3 time. The parameters measured were height plant, diameter of cobs, long of cobs , weight cobs, weight of cron cobs without cron husk. The results showed that the application of 60 gram/polybag with OPEFB compost/polybag +fertilizer, N, P and K recommended dosage can the growth and yield of sweet corn highest compered with the control and othe treatments.   Keyword: Empty Palm Bunch, NPK fertilizer, Ultisol, Sweet corn

Abstract

Mustard is one of broadleaf vegetables are very potential to be cultivated because of the high demand of vegetables. production is likely to increase over the use of inorganic fertilizers and pesticides excessive. At the now widely circulated one is organic fertilizer vermicompost. Provision of vermicompost on soil can improve soil chemical properties, soil physical properties and biological properties of soil.  This research was conducted in the Faculty of Agriculture experimental station, Riau University, campus Bina Widya km 12, 5, Tampan, Pekanbaru, with soil type Inceptisol, from March until May 2013. This study uses a completely randomized design (RAL) with 5 treatments and 5 replicates in order to obtain 25 units of the experiment, namely T0: without giving vermicompost, T1:2ton/ha vermicompost, T2: 4 tons / ha vermicompost, T3: 6ton/ha vermicompost, T4 : 8ton/ha vermicompost. Parameters observed in this study were plant height, number of leaves, leaf area, root volume, and fresh weight of  consumption. vermicompost fertilizer on soil of Inceptisol significant effect on the growth parameters of plant height, leaf number, leaf area, and heavy consumption of fresh mustard plant and not a real effect on the root volume.   Keyword: Mustard greens, Vermicompost fertilizer, Soil inceptisol.

Abstract

Maize production technologies that are available on the fertile land has been able to increase prodnctivityfrom 5.0 to 10.0 tons of dry beans per hectare, but the technology on marginal lands such as peatbinds are notyet avaihibte so its productivity is veiy low. Dregs is alkaline and conuins essential macro and mkro nutrientsso it has potential to be applied as fertilizer and ameliorant in peat The research aimed to study the growth andproduction of sweet com, with application of iregs as ameiiorant and phosphorus source. Peat soil wasobtained from experiment plot, faculty- of ^ricuHure in Rambo Panjang village, Kampar and firqpi was obtainedfrom PT RAPP Kcrinci, Riau. Experiments used completely randomized design of factorial 4x4 which werearacliorant dregs (0, S, 10 and 15 tons/ha) and source of phosphate (SP-M, FA Huinan China, ChristmasIsland and Petrokimia Gresik) and each treatment was repeated 3 times. Dregs characterization resultsshowed that solid waste is not identified as waste according to Rcgulatkin No. B3. No. 18 Jo. 8S Year in 1999.Dregs Applications of 5 tons / ha increased dry weight of straw and crop production of 93-97% and 106-l<3*^ respectively on each source of phosphate compared with no application of dregs. Tbe highest dryweight of straw and production of about 150-260% were obtained at dregs application of 10 tons / ha whiledregs application of 10 tons / ha resulted in the highest production of about 150-260%.

Abstract

This research aimed to investigate the best soaking time for areca seed in young coconut water to improve its germination. This research was carried out in Jalan Limbungan, Limbungan village Rumbai district, Pekanbaru city. This research started from early March to end of May 2005. The method esed in this research was non factorial of completely randomized design with 3 replications. Parameters in this research were the time germination, germination ability, speed of germination, plumulae length, root length, and dry weight of seed. The seed soaking treatments significantly affected all germination parameters except the root length and the best treatment for araca seed is A4 (24 hours of soaking).

Abstract

The objective ofthis research was to determine tJic effect of planting distance on the growth and production ofseveral mung bean varieties cultivated in peat soil. The research was conducted in Tiiah Karya area Sub-District ofSimpangBaru of Panam District. The research method was Randomized Klock Dcsijin (RB1» withthree replications. The data obtained were analysed by ANOVA and continued by LSD at the level of 5 %. Theresult shows that each mung bean variety exhibited a different response when planted in the peal soil withvarious planting d'islance. The best growth of the third varieties was found when cultivated in the plantingdistance of35 x 35 an (J3), and the highest production was observed in the planting distance of 25 x 25 cm (J 1).Variety No.l29 yielded bean of 1,2 ton per hectare when cultivated in the peat soil with planting distanceof 25 X 25 cm.

Abstract

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.

Abstract

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.
