Abstract

Shallot productivity can be increased by taking into account the right fertilizer factor and the potential of the seeds used. The study of potassium and manure dosages and seed size were carried out to get the best treatment in increasing growth and yield. The study was conducted in the Experimental Garden of the Faculty of Agriculture, University of Riau, from February to April 2019, using a divided plot design. The main plot is the difference in seed size (> 5.0 - 7.5 and 2.5 - 5.0) g, subplots of doses of manure (0, 15, 30) ton.ha-1 and children of subplots (0 , 200, 400) kg.ha-1. The parameters observed were plant height, number of leaves, age of harvest, number of tubers per clump, diameter of tuber, tuber fresh weight and tuber dry weight, further tests used BNJ level of 5%. The results showed that the highest dry weight of tubers was obtained in the treatment of large seedlings (> 5.0 - 7.5 g) which were given 30 tons. ha-1 of manure and 400 kg.ha-1 of KCl, with an achievement of 4.1 tons.ha-1.

Abstract

This study aims to produce varieties of shallots (Allium ascalonicum L.) from seeds with better growth and production by adjusting the spacing. The research was conducted at the experimental garden of the Faculty of Agriculture, Riau University, Pekanbaru from May to October 2019, in a factorial completely randomized experimental design in three replications. The first factor is the variety (V), namely: v1 = Sanren, v2 = Lokananta, and v3 = Tuk Tuk. The second factor, the spacing plant (J) was: j1 = 10 cm x 10 cm, j2 = 10 cm x 15 cm, and j3 = 10 cm x 20 cm. The variables observed were plant height, number of leaves per tuber and per clump, leaf length, number of tubers per clump, tuber size, fresh weight and dry weight of tubers per plot. The research data were analyzed ofvariance and followed by orthogonal contrast test at 5% level. The results showed that the interaction between varieties and spacing plant was seen in: number of leaves per tuber and per clump. The number of tubers per hill, tuber diameter, fresh and dry weight of tubers per plot were affected by the variety. The number of tubers per hill and tuber diameter are also affected by spacing plant. Shallots of the Sanren variety increased, if planted at loose spacing, but the production was higher in the Tuk Tuk variety or when planted with more spacing. Keywords: True Shallot Seed, variety, plant spacing

Abstract

 1Mahasiswa Fakultas Pertanian Universitas Riau2Dosen Fakultas Pertanian Universitas Riau  The research aims to isolate and characterize Ralstonia solanacearum cause bacterial wilt on seedlings of Eucalyptus pellitaclon 077 AA and its inhibition by Pseudomonad  fluorescens. The research was conducted at Laboratory of Plant Protection Department PT. Arara Abadi Group Sinarmas, Subregency of Tualang, Regency of Siak, Province of Riau from July to September 2019. The research was conducted using exploration and observation method and then analyzed descriptively. The observation parameters were morphological characteristic, physiological characteristic, virulency, inhibition ability by Pseudomonad fluorescens and bacterial race. Isolation of phatogenic bacteria from seedlings of Eucalyptus pellita clon 077 AA obtains two isolate which has similar morphological characteristic one each other. Physiological characteristic shows that R. solanacearum isolate Rs-2 has similar characters toR. solanacearum on colony colour in medium NAPSA+TZC, negative reaction on gram test, negative reaction on gram staining test, positive reaction on oxidase test and positive reaction on OF test. Virulency test of R. solanacearum isolate Rs-2 towards E. pellita seedlings shows positive reaction so R. solanacearum isolate Rs-2 is pathogenic. The inhibition zone that produced by Pseudomonad fluorescens towards R. solanacearum isolate Rs-2 is 17,3 mm in medium King’s B and 12,4 mm in medium NAPSA and classifies as strong and the mechanism of its inhibition is bacteriostatic. The pathology race test shows that R. solanacearum isolate Rs-2 is Ralstonia solanacearumon race 1.Keywords: Characterization, Eucalyptus pellita, isolation, Pseudomonad fluorescens, Ralstonia solanacearum

Abstract

This research aims to increase the production of rose flower (Rosa hybrida L.) in quality standards by takenthe paclobutrazol which is done at different age of rose cuttings. The research was conducted on the Faculty of Agriculture experimental farden, Riau University, from May 2019 to August 2019. The study was conducted in the 4 x 4 factorial completely randomized design (CRD) in three replications. The first factor: paclobutrazol (P) with 4 concentrations: p0 = 0 ppm, p1 = 125 ppm, p2 = 250 ppm, and p3 = 375 ppm. The second factor: age of rose (W), in stages, was: w0 = 2WAP, w1 = 4WAP, w2 = 6WAP, and w3 = 8WAP. The variables observed were: shoot length, the first time flower budding appeared, the first flower to appeared, the flower stalklength, the flower stalkdiameter, the bloom period, the plant height, the stem diameter, the number of flowers per plant, the largest flower diameter, and the first time harvest aged. The results showed that the flower stalk diameter, the length of the bloom, the stem diameter, and the largest flower diameter were influenced of the interaction between paclobutrazol concentration and the cuttings aged. The first budding appeared, the first flower appeared, the plant height, the number of flowers per plant, and the age of the first harvest were influenced of paclobutrazolconcentration. The standard quality of rose plants from cuttings does taken, if application of ZPT paclobutrazol in 250 ppm while the cuttings were 2WAP.  Keywords: rose flower, paclobutrazol concentration, plant age.

Abstract

Gold snail (Pomacea canaliculata L.) is the main pest of rice plants in Empat Balai Village, Kuok District, Kampar Regency. Farmers in Empat Balai Village experience gold snail infestation every year, which has an impact on production. The purpose of community service activities is to conduct community service by counseling and controlling carp pests in rice fields by utilizing local wisdom in Empat Balai Village. The methods in this service are survey, consolidation, counseling and field practice. The counseling was held at Mushallah Miftahul Jannah in Pulau Empat Hamlet, while the field practice was at the farmer’s house and rice fields in Empat Balai Village. The material provided was about bioecology and how to control the carp snail pest. It was emphasized that the recommended control carp pests are the management of carp pests in the egg phase, because one group of eggs has 500 eggs and control is easier in the egg phase. Control in the egg phase includes making drainage or small ditches, installing bamboo stakes so that the snails lay their eggs there, and collecting the eggs once a week. In the snail phase, involves setting up attractant plant traps (gadung tuber leaf, papaya leaf, and banana leaf), kalambuai traps (kaltrap), installing of irrigated nets, utilizing ducks, and vegetable molluscicides. In addition, preventive measure was taken, such as planting older seedlings. The farmers were very enthusiastic about this activity. As a result, farmers gained additional knowledge about gold snail pests and how to control them, improve farmers skills on gold snail pests control methods by utilizing local wisdom.
