Abstract

The objective of this study was to know the effect of the interaction of a solid compost utilization and cellulolytic microorganisms and to get the best effect on seedling growth of oil palm (Elaeis guineensis Jacq.) In the planting medium PMK in the main nursery.The experiment was conducted at the experimental farm of the Faculty of Agriculture, University of Riau from January 2015 to April 2015.The study arranged experimentally using Completely Randomized Design (CRD) factorial. The treatments consisting of two factors: the first factor utilization of solid compost consists of 4 levels as follows giving of solid compost (0, 25, 50 and 75) g/polybag plants and the second factor giving cellulolytic microorganisms consists of 3 levels as follows giving of MOS (0, 10 and 20) ml/polybag plants. Thus there are 12 combinations of treatment with repeated3timesthen obtained 36 experimental units.Parameters observed were the increase of seeds height, increase of humpconvolution, increaseofleaves, volume of root, rootshootratioanddry weightof oil palm seedlings.Data were analyzed statistically using ANOVA and followed by HSD at level of 5%.The results showed that the interaction of a solid compost utilization and giving of MOS significant effect on the overall observed parameters. Utilization of solid compost 75 g/polybag and giving MOS 20 ml/polybag showed the best result for the overall observed parameters.  Keywords : Elaeis guineensis Jacq.,solid compost, cellulolytic microorganisms

Abstract

Orchids are very popular ornamental plant because it has a diverse kind. The flowers are used for various purposes. One way to increase the growth of Dendrobium orchid by using a mixture of planting media and fertilizer through the leaves, because the fertilizer is already contained nutrients needed by plants orchid. The study aimed to obtain the composition of planting medium with a good concentration of liquid fertilizer for the growth of Dendrobium orchid (Dendrobium sp.) and conducted experimentally at Gerai Tanaman Hias Intan Bertuah in Jl. Arifin Ahmad, Pekanbaru, Riau by using Rancangan Acak Kelompok (RAK) consist of 9 treatment (media fern, wood charcoal, coconut husk, broken bricks with Growmore concentrations of 0.5, 1. 5 and 2.5 g/liter of water) with 3 replications. Each experimental unit contained 3 plants and 81 population. The parameters measured were the number of shoots, plant height, stem diameter, leaf length and leaf number. The results showed that treatment with the composition of planting media with concentration of Growmore fertilizer had not significant effect on all parameters was observed that the number of shoots, plant height, stem diameter, leaf length and number of leaves, whereas treatment ferns planting media composition, wood charcoal, coconut fiber with Growmore 1.5 g/liter of water gives the best results for the parameters of the number of shoots, plant height and number of leaves on the growth of Dendrobium orchids (Dendrobium sp.).

Abstract

This research was intended to determine the possibility of manure application to replace inorganig fertilizer on crop growth and seed yield of soybean. A field experiment was conducted at the experimental farm of the Faculty of Agriculture University of Riau, Pekanbaru in 2013. The experiment was arranged in randomized block designwith seven treatments and three replications. The treatments were recommended rate of inorganic fertilizers (Urea 55 kg/hectare, TSP 55 kg/hectare and KCl 73 kg/hectare), chicken manure at rates of 2 tons, 3 tons and 4 tons per hectare; cow manure at rates of 10 tons, 12 tons and 14 tones per hectare. Seed of G19BE genotype was planted in a plot of 3m x 2 m with the planting space of 40 cm x 20 cm. All rates of animal manure were apllied 10 days before planting while fertilizer was applied at planting date. The results showed that inorganic fertilizer and any kinds of manure affected vegetative growth of soybean at the same manners. Application of cow and chiken  manure, in general, yielded more filled pods, more number of seeds per plant, seed weight per plant and seed yield m -2 than inorganic fertilizer application. Chicken manure ate of 4 ton hectare yielded greater seed weight per m² compared to cow manure or artificial fertilizer. This result suggests that organic manure may be utilized to replace inorganic fertilizer in soybean cultivation.           Keywords: Chicken  manure, cow manure, soybean

Abstract

The research aims to find out the effect of interaction between rice straw compost and NPK fertilizer and get the right dosage for growth and yield of eggplant optimally. The research was conducted at Experimental Garden, Faculty of Agriculture, Riau University, Pekanbaru.  The research was conducted for 5 months, from May to September 2018. The research was conducted experimentally in factorial 3 x 3 using a completely randomized design (CRD). The first factor was the dosage of rice straw compost consists of 3 levels (5, 10 and 15 ton.ha-1). The second factor was the dosage of NPK fertilizer (0, 50 and 100 kg.ha-1.). The observed parameterswere plant height, stem diameter, days of flowering, days of harvesting, fruit diameter, fruit length, fruit weight, number of fruits per plant and production per plot. The observed parameters were analyzed byvariance analysis and followed by Duncan's multiple distance test at level 5%. The results of the research showed thatrice straw compostand NPK fertilizer increased the growth of eggplant such as plant height, stem diameter, days of flowering, increased fruit weight, fruit length, number of fruits per plant, production per plot but  did not accelerate days of harvesting and did not increase fruit diameter. The treatment of rice straw compost at dosage 5, 10 and 15 tons.ha.-1 and NPK fertilizer at dosage 100 kg.ha.-1 gave better result on the growth and yield of  eggplant.Keywords: Eggplant, rice straw compost, NPK fertilizer
