Abstract

Chili (Capsicum annum L.) is one of horticultural commodities has significant economic value, however land in Riau that used for this farming have low fertility as peatland. Therefore the use of organic fertilizer that low complete material is indispensable in improving the productivity of chili, one of the organic fertilizer that is maize rubbish Tricho-compost. This research aimed to determine the effect of multiple dosage application maize rubbish Tricho-compost in enhancing the growth and productivity of chili plants on peatsoil medium. The data were analyzed statistically using analysis of variance followed by Duncan’s New Multiple Range Test (DNMRT) at 5% level and regression analysis  Orthogonal. The result showed that differences in the growth and productivity of chili of several dosage of the treatment, that the provision Tricho-compost with a dosage 15-20 ton ha-1 was found to give highest circle stem, fruit weight per plant and stimulated harvesting time. Tricho-compost with a dosage 20-30 ton ha-1 was found give highest plant height, volume of root, fruit length and stimulated flowering time. Keyword : Chili, corn waste Tricho-compost, peatsoil

Abstract

This research aimed to produce good Cacao (Theobroma cacao L.) seedlings, which is planted on on some grows medium by giving organic liquid fertilizer. This research was conducted at Agriculture Faculty of Riau University, Pekanbaru, on 10 m above of the sea. Started from April to September 2014.  This research used Factorial Completely Randomized Design (CRD) with two factors and three replictions. Factror I: grows medium with 3 levels, M1: Inceptisol soil, M2: Red Yellow Podzolik soil and M3: Peat soil. Factor II: concentration of organic liquid fertilizer with 3 levels, O1: 0%, O2: 0,78% and O3: 1,56%. Parameters observed were the seedlings height, stem diameter, number of leaves and leave area. The result  showed that the use of some grows medium and the organic fertilizer affect the growth of Cacao seedlings. But interaction between both of treatment not affect  the growth of Cacao seedlings. The combination of organic liquid fertilizer concentration 1,56% with Inceptisol soil tended to increase seedlings height and stem diameter, while the combination of organik liquid fertilizer concentration 1,56% with Peat soil tended to increase number of leaves and leave area.

Abstract

This study discusses the potential of rice paddy lines to improve the Ciherang variety as a new variety approved in Riau based on the number of maximum and productive tillers. Research has been carried out in the fields belonging to the farmers of Belading Village, Sabak Auh Subdistrict, Siak Regency, Riau Province. The research done in experiment of a randomized block design (RBD) of 12 rice plant genotypes consisting of 10 repair lines of Ciherang variety and 2 comparable varieties, namely Ciherang and Inpari 33 varieties. Genotypes were planted in one rice field divided into 4 groups according to the direction of water direction irrigation. The observated were maximum and productive amount tiller. The data were analyzed for its variance and differences in the mean of each genotype were calculated by Duncan's New Multiple Range Test (DNMRT) at 5% level using SAS software version 16.0. The relationship between maximum and productive tillers saw in regression and correlation. The results showed 12 genotypes were significant to number of maximum and productive tillers. The lines G1, G2, G3, G4, G5, G7, G8, and G10 were developed as candidates for new varieties collected in Riau based on their maximum and productive tillers. The potential of the G9 strain as a new variety candidate in Riau is better than the lines G1, G2, G3, G4, G5, G7, G8, and G10 based on the number and productive tillers. Keywords: Genotypes, comparison varieties, maximum tillers, productive tillers

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

Onion productivity in Riau was reached 6.1 ton/ha, whereas Indonesian onion productivity has reached 12.3ton/ha, and potential productivity of onions is 14.4 ton/ha. This less onions productivity in Riau is mainlycaused by environmental factors such as climate, the lack of mulch or fertilized calcium. Therefore, toincrease onion productivity in Riau we can use some types of mulch and calcium applying together. A goal ofthis experiment is to increase Riau onion productivity. This experiment had done in the farm of the.AgriculmreFaculty, Riau University in October to December 2003. The experiment was designed with CompletelyRandomized Design in factorial, and the treatment combinations were replicated three times. These factorswere types of mulch in the levels: Without mulch (m,), Grass mulch (nij), Transparence Plastic Mulch (ra,),Black and Silver Plastic Mulch (m^), and doses of Calcium fertilizer in the levels: Without Calcium (K„) and234 lig KCl/ha (K,). The response variables were: sum of slices in each plant, manure weight of the plant perplot (g), dry weight of the plant per plot (g), diameter of hiber (mm), and consumer product per plot (g).Resultsof the experiment showed that there is no interaction between the types of mulch and doses of Catciiun C 'U/hiU-fertilizer in the response variables. The effect of tlic treahncnt combinations could be observed by the types ofmulch only. Black and Silver Plastic Mulch increased the productivity to 9.S ton/ha. This treatment couldincrease manure weight of the plant per plot about llM.6%,dry weight of plan per plot 117.4%, diameter oftuber 27.8%, and consumer product per plot T20,l % when compared to onion without mulch.

Abstract

ABSTRACT            The present study aims to improve the growth of palm oil seedling periodically covered with puddle by giving foliar fertilizer and gibberellin. The research was experimentally conducted at an experimental garden of Faculty of Agriculture, Riau University, Pekanbaru from August until December 2017 using completely random split plot design under 3 replications. The main plot is foliar fertilizer concentration (D) consisting of d0 = non foliar fertilized (0 ppm), d1 = foliar fertilized 1,500 ppm, d2 = foliar fertilized 3,000 ppm and the sub plot was gibberellin concentration (G) consisting of g0 = no gibberellin (0 ppm), g1 = gibberellin 15,000 ppm, g2 = gibberellin 30,000 ppm. The observed consists of: seedling height, total leaf midribs, bar diameter, total adventive roots, roots volume, shoot root ratio, dry seedling weight and seedling quality index. The data were analyzed using analysis of variance and orthogonal contrast tests at a level of 5%. The results that dry weight and quality index of palm oil seedling which are periodically covered with puddle are affected by an interaction between foliar fertilizer and gibberellin, while height seedling and dry seedling weight are affected by gibberellin concentration. The height of palm oil seedling which are periodically covered with puddle can be improved use by gibberellin. The weight of dry seedling can be improved through giving foliar fertilizers with gibberellin, provided that the concentrated are both equal. The improvement of seedling quality index with foliar fertilizer is determined by the gibberellin concentration given. Keywords: Palm oil seedling, periodic coverage of the puddle, foliar fertilizer and gibberellin.
