Abstract

This research aim was to know the dose of potassium fertilizer and different plantspacing of ginger between corn plants to increase produce the ginger crop and cornwhich conducting at multiple cropping system. This research was conducted usingthe Completelly Randomized Block Design of the planning (RAK) factorial con-sisted of 2 factor and 3 repeated. The first factor was potassium fertilizer including0 kg KCl/ha, 100 kg KCl/ha, 200 kg KCl/ha, and 300 kg KCl/ha. The second factorwas different plant spacing of ginger crop including 25 x 35 cm, 30 x 40 cm, and35 x 45 cm. Every treatment and replication was 2 x 2 m. Parameter observed wereheight of ginger crop and corn crop, relative growth rate of ginger crop and corncrop, number of ginger crop, heavy of wet ginger crop, heavy of dry ginger crop,the time of appear that flower of corn, the wind of corn crop, heavy of dry corncrop, and heavy 100 of grain. Analysis was continued by Duncan New MultipleRange Test the (DNMRT) of level 5 %. Research indicate that the giving of potas-sium fertilizer with dose 100 kg/ha and 25 x 35 cm of ginger crop spacing representthe best treatment to increase produce the ginger of each crop and that the giving ofpotassium fertilizer with dose 300 kg/ha and 30 x 40 cm, 35 x 45 cm represent thebest treatment to increase produce the corn of each crop.

Abstract

The Mo is essential for plants, molybdenum cofactor (Moco) forms active site ofall eukarotic Mo enzymes. Nitrate reductase enzyme is available in all plants,which is needed to change NO3- taken by plant to NH3. In legume, Mo is nitroge-nase enzyme component, that is needed in changing N2 become NH3, hat is why Mois very needed in N fixation process. With C, H, and O, sometimes S, NH3 formamino acid whether or not containing S, amino enzyme, nucleate acid, chlorofil,alkaloite and purin base. That is why Mo is very important in forming protein andchlorofil. The research was conducted in green house of universitas Riau Agricul-ture Faculty. Ultisol soil was taken from Rumbai Pesisir region, Pekanbaru city in 0– 20 cm depth. The analysis of soil chemical characteristic before conducting re-search was done in Balai Penelitian Tanah Bogor. The research was arranged incomplete random design consisted of six treatment : 0, 200, 400, 600, 800 and 1000g NH4-molybdate/ha, each treatment was treated three times. The aim of this re-search is to study the effects of application of NH4-molydate to crop growth andSoybean yield. The result showed that aplication of 600 g NH4- molybdate/ha haveimproved the crop growth and increased the soybean yield by 65,61 % comparedto control.

Abstract

Kampar District is one ofriceproduction centres in Riau, so it is important to develop SRI (System of RiceIntensiOcation) method. To apply this method, we should know therightdbunce for thericeto be plantedbecause the farmers stfll use pbinting disUnce of25 x 25 on. The research used Randomized Block design,with four treatments and three repltcattoas. The treatment is the planting distance as ibUow: 25 1 25 cm (SI),30 X 30 cm (S2), 35135 cm (S3) and 40 x 40 cm (S4). The result of analysis was tested by Duncans NewMultiple Range Test (DNMRT) at 5% level. The research result showed that by SRI method, thericepiantgrow and produce very well with planting distance of 40 K 40 cm and the production of dry unpolished grainis 6^8 kg per plot.

Abstract

The research was conducted to evaluate the effect of treatment or addition of oil palms ash and various kindsmulch on the growth and production of chilli (Capsicum annuum. L). The experimental method used wasrandomized block design method with 2 factor namely 1) Various dosages of oil palms ash and 2) Variouskinds of mulch. Parameters observed were the height of pLmt, number of primary branchs, number of fruitsper plant and weight offruits per plant The experimental results show that interaction between oil palms ashand mulch significantly influenced the growth and production of chilli. Addition of ash significantly increa.sedthe number and weight of fruits per plant Treatment with mulch only increased the number of fruit per plant.

Abstract

This research aimed toknow influence of interaction of mashitam organic fertilizer dosage and NPK 25:7:7 to the productivity of cabbage (Brassica oleracea var. Capitata L.). the Treatments were arranged in a factorial 3x3 of Completely Randomized Design with 3 replications. The first factor was mashitam organic fertilizerdosage of 3 levels namely 250, 500, and 750 kg/ha and the second factor was NPK 25:7:7 dosage of 3 levels namely 0, 70, and 140 kg/ha. Parameters observed were cabbage crop forming time, harvest age, crop diameter and fresh weight of cabbage crop. Application of 500 kg/ha mashitam organic fertilizer and 140 kg/ha NPK 25:7:7 provided the highest result.

Abstract

This study aims to determine the effect of household organic waste liquid fertilizer on the growth and production of peanutsand determine the concentration of good liquid organic fertilizer. The experiment lasted for 4 month from November 2017 to Februari 2018 experimental garden of Agricultural Faculty of Riau University. This research using a randomized block design (RDB) consisting of five treatments and four replications. The treatment given is K0 = 0 ml POC.l-1 water, K1 = 2.5 ml POC.l-1 water, K2 = 5 ml POC.l-1 water, K3 = 7.5 ml POC.l-1 water, and K4 = 10 ml POC.l-1 water. The parameters observed were plant height, age of flowering plants, harvest age, number of pods per plant, percentage of pithy pods, number of seeds per pod, dry seed weight per m2, and weight of 100 seeds. The data obtained were analyzed using Anova and Duncan on levels 5%. The results showed that household organic liquid fertilizer can affect plant height, age of flowering plant, harvest age, number of pods per plant, number of seeds per pod, dry seed weight per m2, and weight of 100 seeds. The concentration of household organic liquid fertilizer7.5 ml.l-1 water and 10 ml.l-1 water give the best results in increasing the production of peanut plants.Keywords: Peanuts, concentration, liquid organic fertilizer

Abstract

This study aims to see the effect of banana peel fermentation as liquid organic fertilizer on the growth of rose plants and determine the best dosage for the growth of rose plants. This research was conducted at the Faculty of Agriculture, University of Riau's experiment station from August to November 2017. This research was conducted in the form of an experiment using a non-factorial complete randomized design consisting of 5 levels and 3 replications. Fermented banana peel as a liquid organic fertilizer consists of 0, 150, 300, 450, 600 ml per polybag. The parameters observed were the number of shoots, length of shoots, number of leaves, when the first flower appeared and the number of blooms. The results showed that administration of banana peel fermented as a liquid organic fertilizer significantly affected the number of shoots, number of leaves, when the first flower appeared and the number of flowers. Provision of banana peel  fermentation as a liquid organic fertilizer with a dose of 450 ml per polybag gives the highest yield for the growth of rose plants.Keywords : Rose, liquid organic fertilizers, dosage
