Abstract

The main obstacles in the commercialization of seedlings mass propagation through tissue culture techniques is the high cost of the culture media component. therefore, the production of lowcost tissue culture is required. This study aims to develop low cost in-vitro media for the production of the seedlings of Barangan banana. The research was composed following Factorial Completely Randomized Design, the first factor was Terra Novalgro liquid fertilizer with three concentrations, namely 1, 2, and 3 ml L-1, while the second factor was Gandasil with 3 concentrations namely 1, 2, and 3 mg L-1, so obtained nine treatments, each treatment was repeated 10 times, so that there were 90 experimental units. MS media was used as control. The parameter observed was number of shoots, number of leaves and number of roots. The results of this study exhibited that the treatment of 1 ml L-1 liquid fertilizer + 2 mg L-1 foliar fertilizer produced 9.30 shoots/explant and 1.90 leaves/explant, that no significantly different from MS medium (control) which produced 9.0 shoots/explant and 0.3 leaves/explants. Therefore, the using completed liquid fertilizers and foliar fertilizers as medium in vitro propagation of barangan bananas can become an alternative replace MS medium, as well as reduced the cost of culture media as 91% -93% compared to MS media.

Abstract

Weed vegetation analysis is important to do in order to know the composition and structure of the vegetation to determine the appropriate weed control measures. This study aims to compare the composition and structure of weeds on peatland immature oil palm plantations and mature palm. This research was conducted from October to December 2020. Vegetation analysis was carried out using a survei method with purposive sampling technique. The parameters observed were density, frequency, dominance, important value index (INP), summed dominance ratio (SDR) and species diversity index (H'). The results showed that the composition of weeds on immature oil palm plantations was found 12 species with number of individual 847, while on mature palm found 9 species with number of individuals 980. The dominant weed structure on immature oil palm plantations is Lempuyangan with SDR values 29,9 % and mature palm is Bandotan with SDR value 23,4%. Weed diversity index on immature oil palm plantations and mature palm is categorized as high with a value of 1.50 for immature oil palm plantations and 1.65 for mature palm.

Abstract

 Riau is a province in Sumatra Island with the widest peatland covering up to ± 4,04 million Ha or about 56,1% of the area, with various type of peat, including the potentially submerged peat area.  With the peat charasteristics drawbacks such as low nutrient content and relatively high acidity, cause this type of land  barely cultivated for horticulture crop such as shallot. Whilst, in Indonesia, shallot is part of daily society culinary component. Therefore, efforts are needed to make use of peat land for this type of commodity by overcoming the shortages, for example by applying Trichocompost combined with Grand-K fertilizer. This research thus aimed at evaluating the growth and yield of shallot in potentially submerged peat soil, treated with Trichocompost and Grand-K Fertilizer. Experiment was conducted on peat soil   in Labersa Street Kelurahan Simpang tiga Kecamatan Bukit Raya Kota Pekanbaru for three months, from October to December 2019. The experiment was arranged in completely factorial design with two factors; each at four levels. The factors were Trichocompost (at 0, 2, 4, 6 ton ha-1) and Grand K fertilizer (at  0, 50, 100, 150 kg ha-1). The parameters observed were the percentage of seed viability, plant height, number of leaf, number of tuber, and the yield per plan. Results of the experiment showed that the best combination of treatment was Trichokompos at 4 – 6 ton ha-1 dan Grand K at 150 kg ha-1.

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

Kenikir is an indigenous plant that has the potential to be cultivated, but there are still many people who do not know the potential of kenikir. This research aims to study the effect of shoots harvest on the results of kenikir and to find the best concentration of liquid organic fertilizer rabbit urine for the growth of kenikir. This research was conducted in January - April 2020 in the experimentation field of Perjuangan University of Tasikmalaya at an altitude of 359 m asl. The design used was a two factor Randomized Complete Block Design (RCBD). The first factor is the age of harvest, consisting of 3 levels ie 7 WAP (Weeks after planting), 8 WAP and 9 WAP. The second factor is urine concentration consisting of 4 levels ie 0 ml.L-1, 10 ml.L-1, 20 ml.L-1 and 30 ml.L-1. The results showed that 10 ml of L-1 U2 treatment produced higher kenikir plants and thicker diameters. U2P3 treatment gave the best response to plant height variables. All treatment combinations gave the same response to the number of leaves harvested and the weight of fresh shoots

Abstract

Aphis gossypii Glover is the main pest that attacks chili plants. Control efforts that are often carried out are by using synthetic insecticides. Safe pest control is the use of vegetable insecticides. Srikaya is a plant that can be used as a botanical insecticide. The purpose of this study was to obtain an effective concentration of srikaya leaf powder extract against A. gossypii pest mortality. This research was conducted at the Plant Pest Laboratory of the Faculty of Agriculture, Riau University from March to July 2019. The study was conducted experimentally using a completely randomized design (CRD) with 6 treatments and 4 replications. The treatments given were extracts of srikaya leaf flour with the following concentrations: Srikaya flour with a concentration of 0 g.l-1 water, 20 g.l-1 water, 40 g.l-1 water, 60 g.l-1 water, 80 g.l-1 water, 100 g.l-1 water. The parameters observed were the initial time of death of Aphis gossypii, Lethal time 50 (LT50), daily mortality, total mortality, Lethal concentration (LC50), temperature and humidity. The results of this study indicate that the application of the extract of srikaya leaf flour (Annona squamosa L.) on concentration of 40 gl-1 srikaya leaf meal was an effective concentration to control A. gossypii which can cause total mortality of 82.5% with LC 50% is 1.37% or equivalent to 13.7 gl-1, and the right concentration to kill. 95% of pests is 6.37% or equivalent to 63.7 gl-1.
