Green beans (Vigna radiata L.) is a food which have a high nutrition, so many consumed by the people. The need of green beans in Indonesia increased in every year,while production of green beens in Indonesia not enough to cover the need of green beens in Indonesia. The research aims to know the effect of ameliorant and the number of earthworms to growth and yields of green beans, and to get the right combination to increase the growth and yields of green bean. This research was implemented in the green house Technical Service Unit (UPT),Faculty of Agricultur Riau University. This research use the complete random design(RAL)that was arrangement two factors and three repeat. The first factor is three level of ameliorant and the second factor is four level number of earthworm. The parameter of observation is plant height, diameter of stem, number of primary branch, flower appearance age, harvest age, the number of pods per plant, the number of dryseeds per plant and the weight of dryseeds per plant. Giving of 10 ton.ha-1 chicken manure and 9 earthworms per plant show the better result to plant height, diameter of stem, number of primary branch, harvest age, the number of pods per plant, the number of dry seeds per plant and the weight of dry seeds per plant.

The aim of this research is to know the influence of giving feces of horned beetle larvae (O. Rhinoceros) towards soil and plants in obtaining exact dose to the growth of Arabica coffee seedling (Coffea Arabica L.). This research has been conducted in Experimental Station of Agriculture Faculty of Riau University, Campus Bina Widya km 12,5 Simpang Baru Village, Tampan Sub District, Pekanbaru City. This study was conducted from March to July 2017. This study was conducted using a Complete Randomized Design (CRD). The treatment was the feces of horned beetles larvae which consists of six dose levels, such as: K0 : 0 g each plant, K1: 25 g each plant, K2: 50 g each plant, K3: 75 g each plant, K4: 100 g each plant, K5: 125 g each plant. Each treatment was repeated three times to make 18 experimental units. Data obtained from the observations were analyzed using variance analysis (Anova). Diversity results are followed by Duncan multiple range test at 5% level. Observed parameter were seedling height, the increase of stem diameter, the increase of leafs number, leafs area, roots volume, shoot root ratio and seedling dry weight. The results show that feces of horned beetles larvae application can increase the chemical properties of the soil such as N-total, P-total, K-total, C-organic, pH and decrease C/N ratio on subsoil Inceptisol. The application of this fertilizer increases the number of leafs, stem diameter, roots volume, seedling height, leafs area, and dry weight. Applying 100 g feces of horned beetles larvae have shown good growth for vegetative growth of Arabica coffee seedling on subsoil Inceptisol. Keywords: Arabica coffee seedling, feces of horned beetles larvae, subsoil Inceptisol

Sweet corn (Zea mayssaccharata Sturt) is widely used because it has a relatively high nutritional content and sugar content so it tastes sweeter than ordinary corn. Efforts to increase the productivity of sweet corn are proper fertilization. One type of organic fertilizer that can be used is green manure. Green manure comes from plant leaves that are immersed in the soil fresh, one of which can be used as green manure, namely kirinyuh (Chromolaena odorata).This study aims to see the effect of the interaction of green manure kirinyuh and NPK on the growth and production of sweet corn plants and to get the best dose which is carried out in the experimental garden of the Faculty of Agriculture, Riau University, Bina Widya Campus KM 12,5 SimpangBaru sub-district, Tampan District, Pekanbaru, lasts for five months, from August to December 2019. The treatments were given first, namely the dose of kirinyuh fertilizer and the second was the provision of NPK fertilizer. From the two factors, 15 combinations wereobtained, each combination was repeated 3 times so that there were 45 experimental plot units. The data obtained were analyzed using variance and followed by Duncan's test at the 5% level. Based on the results of the research that has been carried out, it can be concluded that the administration of kirinyuh 15 ton.ha-1 and75 kg.ha-1 NPK fertilizer is the best treatment in increasing the growth of sweet corn plants. Keywords: Sweet corn, Kirinyuh Fertilizer, NPK Fertilizer

This study aims to determine the effect of interaction of several doses of rice husk charcoal and NPK fertilizer to the growth of cocoa seedlings and to get the best dose of fertilizer from rice husk charcoal for the growth of cocoa seedlings (Theobroma cacao L.) This research has been carried out in the Technical Implementation Unit of the Garden Trial Faculty of Agriculture University of Riau, Bina Widya Road, Simpang Baru Village Tampan District, Pekanbaru City. This study lasted for four months starting from May until August 2016. This research is a 3x3 factorial experiment prepared according to a complete randomized design (RAL). The treatment in this research is: first factor is rice husk charcoal consisting of 3 levels: A0 = Without giving of rice husk charcoal, A1 = 1 kg of rice husk charcoal per polybag and A2 = 2 kg of rice husk charcoal per polybag. The second factor is NPK fertilizer consisting of 3 levels: P0 = No NPK fertilizer, P1 = 15 g NPK fertilizer per polybag and P2 = 30 g NPK fertilizer per polybag. This study consisted of 9 treatment combinations, and repeated 3 times so that there were 27 experimental units. Each experimental unit consists of 3 plants, so the total plant is 81 plants. The data obtained were analyzed statistically by using vocabulary. The variance was then tested further by Duncan's multiple-range test of 5%. The parameters observed were cocoa seed height, stem diameter, leaf number, leaf area, root volume, root canopy ratio and dry weight of plant. The results showed that the interaction of several doses of rice husk charcoal and NPK fertilizer gave no significant effect on stem diameter, leaf number, leaf area, root volume, dry weight and root ratio of cocoa seedlings. The interaction treatment of rice huskcharcoal 2 kg per polybag and NPK dosage 30 g per polybag tends to give effect to the parameters of plant height and stem diameter while the parameter of leaf number does not occur tendency increase.Keywords: Cocoa seeds, rice husk charcoal, NPK fertilizer

This research aims to determine the interactionof chicken manure and oil palm bunch ashand to get the best dose to the cocoa seedlings growth. This research has been carried out in the experimentalstation Faculty of Agriculture, University of Riau from June to September 2016. This research used a completely randomized design (CRD) two factors with three replications. The first factor is the chickenmanure with four levels namely 0, 10, 15 and 20 tons/ha. The second factor was the oil palm bunch ash with three levels namely 0, 2 and 3 tons/ha. Parameters observed were plant height, girth trunk, number of leaves, root volume, the weight of dry biomass andshoot and roots ratio. The results showed that the interaction of chicken manure and oil palm bunch ash significantly a effect on plant height and shoot and roots ratio, the best treatment can be obtained by providing a dose of chicken manure 20 tons/ha and oil palm bunch ash dose of 3 tons/ha. Chicken manure gives the best treatment results with dose of 20 tons/ha significantly effect on plant height, number of leaves, root volume, biomass dry weight and shoot and roots ratio. Provision of oil palm bunch ash to the cocoa seedlings affect only the root volume and the best treatment is on oil palm bunch ash dose of 2 tons/ha.Keywords: Chicken minure, Oil palm bunch ash, Cocoa seedlings
