Abstract

Application Some Types of Organic Fertilizer in a Pack To Suppress Clubroots and Improve Cabbage (Brassica oleracea L.) Plant Growth Cabbage is one type of leaf vegetables from subtropics area that has been known for a long time and cultivated in Indonesia. One of the hardest cabbage diseases is clubroots caused by the Plasmodiophora brassicae pathogen. This pathogen can cause high damage to cabbage plants. The used of synthetic pesticides is less success in the implementation, and caused environmental pollution, especially the soil, this study tried to control clubroots in the cabbage by using 8 types of organic fertilizer in a pack. This study used a Completely Randomized Design (CRD) with 9 treatments including controls with three replications. The results obtained four best treatments that were effective in suppressing clubroots while increasing the leaf height, leaf amount, leaf area, and maximum dry weight of the plants, that three best treatments were organic fertilizer PSBN, Multitonik, and Biotonik. The best treatment to suppress clubroots is found in organic fertilizer PSBN, Multitonik, and Biotonik which has the lowest percentage of ulcer attack by 33,33-55,56% compared to control (100%).

Abstract

Effect of Harvest Time on the Save of Long Bean Seeds (Vigna sinensis L.). Supervised Long bean plants have indeterminate growth type, ie vegetative growth is still active even though it has entered the generative growth phase. The indeterminate growth type causes the pods to form cook not at the same time. When harvesting long bean pods for quality seed production, it needs to be studied. The seeds before planting must undergo a process of storing both short and long term storage, so the seeds saving power that produced from the time of harvesting different pods also needs to be studied. This study used a completely randomized design (CRD) with three treatments when harvesting pods for seeds, namely physiological pre-cooking, harvesting at physiological ripe, and harvest after physiological cooking. The treatment was repeated nine times. The results showed that the treatment of harvest time had an effect on the shelf life of the beans. Harvest time when physiologically cooked has the longest shelf life compared to harvest time after or before physiological cooking. Seed quality when harvested physiologically during storage obtained the highest compared with the quality of seed yields before and after physiological cooking.

Abstract

Vesicular Arbuscular Mycorrhizae Identification of Arabica Coffee(coffea arabica L.) and Robusta Coffee (Coffea robusta L.) Rhizosphere andIts Spore Multiplication in Zeolite Media.The high demand of coffee in the world led the farmers to improve coffee productivity by using inorganic fertilizers. Considering potential problems that may occured due to inorganic fertilizer use, aplication of biological fertilizer which one of them is containing Vesicular Arbuscular Mycorrhizae (VAM) could be expected to assist the growth of Arabica coffee and Robusta coffee plants in more naturally manner. This study aimed to determine the types mycorrhizal of rhizosphere coffee plants and determine the effectiveness of zeolite media and corn symbiont plant in propagation of VAM. The study began in April to August 2015. Spore isolation was done by conducting wet sieving method. Roots colonization percentages were calculated by root staining method and spores multiplication through trapping culture method. The results showed that VAM spores found in the rhizosphere arabica coffee plants are two genera VAM Acaulospora and Glomus, whereas in robusta coffee plant found three genera Acaulospora, Glomus, and Gigaspora. Mycorrhizal structures found in the rhizosphere of Arabica and Robusta coffee plants were arbuscular, vesicles, hyphae and inner spores. Corn symbionts plant and zeolite media were good combination for the propagation of VAM spores.

Abstract

AbstractTomato Seed (Lycopersicum esculentum Mill.) Storability of Some Extraction Techniques Results                 Shelf life tomato seeds produced by different seed extraction techniques studied using completely randomized design ( CRD ) with three treatments of seed extraction technique and nine replicates. Three seed extraction techniques used are: extraction technique with 2 % HCl, washed with water extraction techniques, and extraction techniques with immersion in water for 24 hours. The seeds are dried until the moisture content ranges from 5 %, then stored at room temperature. Observations before storage include: seed moisture content, the amount of seed moisture content of 5 % per 5 g of seeds, seed purity, germination and speed of germination. Observations during storage include: seed moisture content,  germination and speed of germination. The results showed that the extraction technique of soaking seeds with 2 % HCl able to produce seeds with the lowest percentage of impurities so that the absorption of moisture during the storage period was also the lowest. Extraction technique of soaking seeds with 2 % HCl able to maintain the viability of the seed germination above 80 % until the 12 -week storage period at speeds high enough to germinate. While the seeds of other extraction techniques which have a shorter shelf life. Further research on the storage technique that is able to maintain the viability and vigor of tomato seeds for a longer shelf life.   Key words : Tomato seeds, extraction, seed storage, viability, vigor
