Abstract

Effectility of some Extract to Larvae of Plutella xylostella Development in the LaboratoryThe research was conducted in November 2017 to Februari 2018 in Udayana University Plant Pest and Disease Laboratory. The aim of this research is to know the ability of some plant leaf extract to larvae of Diamonback Moth (Plutella xylostella) development in the laboratory. Plant extract materials used in this experiment were leaf of Lantana camara, Chromolaena odorata, Tithonia diversifolia, and Nicotiana tabacum. Process of extracting was done in Laboratory of Genetic Resources and Molecular Biology Faculty of Agriculture Udayana University. This research uses Completely Randomized Design (CRD) with 4 treatment of leaf extract at 10% concentration and 1 without treatment (control), each treatment was repeated 10 times. Observations were made until the larvae does not do activity or until become adult. Testing of four types of plant leaf extracts showed the following results: Each of C. odorata leaf extract, L. camara, T. diversifolia and N.tabacum used as research material had different potential in suppressing P.xylostella development. Application of L. camara, T. diversifolia and N. tabacum on larvae can develop through 4 instars before becoming pupa, treatment with plant leaf extract is most effective to suppress the development of larvae biology P.xylostella is a leaf extract of C. odorata that result were 100% mortality on larvae stase and the lowest is on the treatment of N. tabacum extract were 20%.

Abstract

The Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Growth and Results of Peanut (Arachis hypogaea L.) This study aims to determine the type of rhizobacteria that have better ability to improve the growth and yield of peanut. The design used was randomized block design with 5 treatments is RB35 (undis rooting plants from Beratan, Sukasada), RB36 (undis rooting plants from Kubutambahan, Buleleng), RB3 (kara benguk rooting plants), RB9 (lamtoro rooting plant) and Controls. Each treatment repeated 5 times. This study observed plant height, number of leaves, number of branches, chlorophyll content, number of root nodules, weight of oven dry roots, weight of oven dry stalks, number of pods per plants, number of pods contain per plants, weight of 1000 seeds, dry seeds weight of oven and predicted yield per hectare. The results showed that the four rhizobakteria there are RB35, RB36, RB3 and RB9 able to increase the growth and yield of peanut plants. From the four rhizobacteria, there are 3 rhizobacteria that have higher ability in increasing peanut yield of RB35 (3.72 tons ha-1), RB36 (3.68 tons ha-1) and RB3 (3.50 tons ha-1) compared to RB9 (3.25 tons ha-1) of plants without rhizobacteria or control (2.04 tons ha-1).

Abstract

Influence of Some Packages of Technology to Fusarium Wilt Disease Development on Cayenne Chili Plants (Capsicum frutescens L.) and Long Chili (Capsicum annuum L.) in the HighlandsThe research was conducted in order to determine the influence and effectiveness of some technologies of Trichoderma sp. compost, rain shelter and pesticides to control the development of fusarium wilt disease on long chili and cayenne chili plants in the highlands. This research was done from September 2017 to February 2018, taking place in Pancasari Village, Buleleng Regency and in the Laboratory of Plant Disease, Udayana University. The study used a Factorial Randomized Block Design with two factors and replicated four times. The first factor was chili type, long chili and cayenne chili. The second factor was the use of technologies, Trichoderma sp. compost, rain shelter and pesticide. The variables observed in this research were symptoms and percentage of fusarium wilt disease. The results showed that all treatment technologies effectively suppressed disease development when compared to control treatment. Percentages of damage by fusarium wilt disease on Trichoderma sp., rain shelter, pesticide and control treatment were 22.50%, 23.75%, 27.50% and 45.00%, respectively.

Abstract

Effectivity of Some Extract to Diamonback Moth (Plutella xylostella) Population On Cabbage PlantThe research was conducted in November 2017 to February 2018 at Candikuning Village, Baturiti District, Tabanan Regency. The aim of this research is to observe effectiveness some extract on larvae of Diamonback Moth (Plutella xylostella) population on cabbage plant. Plant extract materials used in this experiment were leaf of Chromolaena odorata, Lantana camara, Tithonia diversifolia and Nicotiana tabacum. Process of extracting at Laboratory of Genetic Resources and Molecular Biology Faculty of Agriculture Udayana University. This research uses Randomized Block Design (RBD) with 4 treatment of leaf extract at 10% concentration and 1 without treatment (kontrol), there treatments was replicate 5 times. Observations were made on cabbage plants one week after planting and before application. Subsequent observations were conducted weekly, up to harvest by calculating the population larvae of Plutella xylostella. Testing of four types of plant leaf extracts showed the following results: Each of C. odorata leaf extract, L. camara, T. diversifolia, and N. tabacum used as research material had different potential in suppressing P. xylostella populations . Application of C. odorata and T. diversifolia leaf extracts was able to suppress P. xylostella populations faster than other treatments. The weight of cabbage crop on treatment of C. odorata was higher than that of other treatments and the quality of crop in all four types of extract showed quality category 2.

Abstract

Evaluation of Land Suitability of Plantation Commodities in Mandosawu Village Poco Ranaka Sub-District, East Manggarai RegencyThe research aims to evaluate land suitabilty of plantation commodities in Mandosawu Village Poco Ranaka Sub-district. The commodities that are evaluated include cloves, robusta coffee and vanilla. Homogeneous land units based on the result of physiographic analysis and overlapped type of soil, land used and slopes. Evaluation of Land Suitability is a way to know the limiting factor in the research area. Land evaluation conducted by matching method between land characteristic/quality with growth requirement of plant evaluated. The actual land suitability assessment for the three plantation commodities was very appropriate (S1) until appropriate marginal (S3) with temperature, water available and nutrients available (P2O5) become dominant limiting factors. Improvement of land suitability class can be done with improvement effort except rainfall, soil texture, soil depth, moisture and temperature because it is a permanent divider. Fertilization and addition of organic matter can increase the class of land suitability from appropriate marginal (S3) to very appropriate (S1). Results of analysis are used to determine the land managament recommendations on research location. Nonetheless, these results suggested to be applied, for considerations of land conservation as well as farmers welfare.
