Abstract

Lygodium circinnatum (Burn.f.) Swartz is a wild Pteridophyta which is used as a material for handicraft. Recently, Lygodium has been rare in nature due to overgathering. Domestication of this wild plant may required to overcome this problem. A research concerning domestication of Lygodium was conducted at Faculty of Agriculture of Udayana University during March to October 2009. Dose of urea fertilizer in varied levels was applied to 8 month-old sphorophyte. The level of urea doses were 0, 100, 200, 300 and 400 mg urea per plant. The results showed that urea fertilizer significantly stimulated the number of “sulur” (“sulur” is an organ of Lygodium that used as material for handicraft) , but did not affect the number of leaves and plant height. Dose of 300mg urea per plant resulted in the highest number of the average of “sulur” number per plant.

Abstract

Effects of Harvesting Time and Types of Legume Cover Crop on SoilQuality in Dryland Farming. Dryland is characterized by limited water resources, itdepends on amount and distribution of rainfall and its low quality of soil. Effort onimprovement of soil quality have been reported could be done through incorporating biomassof legume cover crops (LCC). Time of harvesting (then incorporated) and types of LCCdetermine the nutrients in the biomass, which finally affects the soil quality. A fieldexperiment was conducted to study the effects of time of harvesting and types of LCC on soilquality in dryland farming area in the village of Sengguan, Gianyar Regency, Bali Provincefrom August to December 2015. The experiment was arranged in a completely randomizedblock design with three replications. The treatments were the times of harvesting (or thenincorporation) (3, 6 and 9 weeks after sowing or WAS) was assigned as the first factor whiletypes of LCC (Mucuna pruriens L. (kara), Crotalaria juncea L.(orok-orok), and Phaseoluslunatus L. (kacang arbila)) as the second factor. Results of experiment indicated thatincorporated LCC biomass significantly (P<0.05) increased soil quality (physically,chemically and biologically). Mucuna pruriens and Phaseolus lunatus harvested and thenincorporated at 3 WAS significantly (P<0.05) increased chemical (organic-C, total-N,available K) quality of the soil, while when harvested 9 WAS the effects were moresignificant on physical (bulk density and porosity) quality. Soil moisture content increasedwhen Phaseolus lunatus was harvested and incorporated at 3 WAS, while microbial activities(indicated by soil respiration) increased when Mucuna pruriens was treated at the same time.

Abstract

The Spores and Genus Number of Endomikoriza on soil of Citrus Orchard Soil in Monoculture (Citrus nobilis Tan.) and Intercrops with Vegetables in Sekaan Districts Kintamani. Endomycorrhiza is a wide spread fungi that develop symbiotic association with numerous plant types except for Brassicaceae and Chenopodiaceae. Endomycorrhizal fungi colonized plants through spore or hypha propagation. The spore number of endomycorrhiza was studied in the soil of orange orchard in the Bali’s center of orange fruit production located in Sekaan Village, Bangli District during November 2015 – January 2016. The orange plants were cultivated in monoculture and intercropped with the following vegetable crops : cucumbers (Cucumis sativus L), tomatoes (Solanum lycopersicum), mustard greens (Brassica rapa subsp. Pekinenshis), and cabbage (Brassica oleracea var. capitata). Three replications of soil samples were taken purposively and separately proceed for laboratory analysis. The following parameters were measured: total spore number and genus types of endomycorrhiza, the content of soil available-P, soil pH, and soil organic-C. The experiment result showed that monoculture system had significant higher number of VAM spores (347 spores) compared to intercropping (178 – 224 spores). Most of VAM spore had small size ranging on 45 – 105 ?m (60,80%) followed by 106 – 249 ?m (33,82%) and the least were ? 250 ?m spores. There were two MVA genus present in the soil of both cropping patterns which grouped to Acaulospora (3 morphotypes) and Glomus (11 morphotypes). The highest number of VAM spores belongs to Glomus.The soil properties that closely related to VAM spore number was soil pH (=0.66**).

Abstract

Productivity of Pepper Seeds Which are Treated Dry Heat Treatment and Storage Pepper plants (Capsicum frutescens L.) is one type of horticultural crops which is very high usage levels therefor, it is necessary to increase productivity dramatically. One effort to fulfil the need is preparing healthy seed with long shelf life . This study aims to determine the growth and yield of pepper plants whose seed was treated with dry heat treatment and storage. The experiment was conducted in Br . Marga Tengah, Kerta Village, Payangan District, Gianyar Regency, since May to October 2013. This study used a randomized block design (RBD) with two factors and four replications. The first factor is treated seeds by dry heat treatment at two levels i.e. given dry heat treatment at 70OC for 72 hours (D1) and without dry heat treatment (D0). The second factor is the storage of seeds with three levels, namely: non-stored seeds (T0), seed stored 2 months (T2) and the seeds stored for 4 months (T4). The results showed that there was no interaction between treatment with dry heat treatment and seed storage treatment of all variables of growth and yield of pepper plants. Dry heat treatment resulted the better growth and yield compared to non dry heat treatment. An increase in the number of fruit harvest as much as 33,43% and increased the weight of the fruit harvest per hectare as much as 33,79% on dry heat treatment compared with no dry heat treatment. Treatment of seed storage until the shelf life of 4 months did not affect the growth and yield of pepper plants.

Abstract

Induction of Mutation of Red Chili (Capsicum Annuum L.) Using Ethyl Methanesulfonate at Several Soaking Periods.One way to increase genetic variation is through induced mutation usingchemical mutagen. Ethyl methanesulfonate (EMS) is a chemical compound that can cause mutationsand commonly used in plant. In this study seeds of red chili were treated using EMS 1% through seedsoaking. Seeds of red chili were soaked with EMS 1% in phosphate buffer pH 7 for 6, 9, 12 and 15hours at room temperature. As control, seeds were soaked in phosphate buffer pH 7. This study aimsto evaluate, physiological and reproductive characters of plants after treated with EMS. Experimentwas conducted in an open field with 5 replicates for each treatment. Results showed that concentrationof chlorophyll a, b and total chlorophyll increased in plants derived from seed treated with EMS 1% for9 hours compared to control and other soaking periods. Soaking seeds with EMS 1% for 12 hoursincreased viability of pollen compared to control and other treatments. The first time of floweringoccurred earlier at 6 and 9 hours soaking period.
