Abstract

Shade is one of the obstacles in the cultivation of soybean crops in intercropping systems. This study was aimed at determining the change in the characters of agronomic and morpho-physiological leaves of soybean plants due to shade. The experiment was conducted at the Experimental Farm of Agriculture Faculty, Teuku Umar University Meulaboh in West Aceh, from August to November 2013. The experiment was arranged in a split plot design with three replications, where subplot (varieties: Anjasmoro, Kipas Merah Bireun, Grobogan, Burangrang, Sinabung, Kaba) was nested in the main plot (shade: without shade, 25% and 50% shade). The results showed that the shade and varieties exerted high significant effects on changes in agronomic characters and morpho-physiological leaf variables, except 100-seed weight and ratio of chlorophyll a/b which were not affected by shade and the amount of chlorophyll b and the ratio of chlorophyll a/b not affected by varieties. Interactions between shade and varieties were highly significant on changes in agronomic characters, except variables 100-seed weight.

Abstract

Peanut has high economic value because has high nutritions especially protein and fat, but the development of broad harvesting and peanut production for the last five years (2008-2012) continues to decrease. The main problem of the peanut low production are disease attacks S. rolfsii and the low broad harvesting. The drop of peanut production in Nusa Tenggara Barat causing harm caused by fungi S.rolfsii can reach 58,3 % per year. Peat is potential land to be developed to farming land. Peat has high acidity so fungi S. rolfsii would be easy to develop and resulted disease severity of peanut disease. Solution of this problem is the gift of lime. This study aims (1) to test the effect of dosages of lime to peanut resistance which was infected by rot stem S. rolfsii on peat land; (2) to study interaction of peanut varieties and dosage of lime to rot stem disease attacks S. rolfsii on peat land. This study used factorial block randomized design 2 x 3 with 3 replications. The studied factors were peanut varieties and the dosage of lime. The result showed that on the effect of varieties, the widest disease percentage was on Takar 2 variety on age 21, 28, 42, and 49 day after planting (DAP) that significant difference with Bison variety. The worth disease intensity was on Takar 2 variety that significant difference with Bison variety (on age 45 and 60 DAP). Key words: dosage of lime, peanut varieties, peat land, the sclerotia of Sclerotium rolfsii

Abstract

Peat soil has a high acidity levels, causing low fertility rate, but can be lowered by amelioration. Ameliorant materials that are widely used today are dolomite and limestone which contains calcium carbonate (CaCO3). All material containing Ca compounds can be used as ameliorant material to neutralize the soil acidity that basically adding Ca and lower Al. Waste shells also have the main ingredients in Ca compounds in the form of calcium carbonate (CaCO3) at higher levels when compared limestone, egg shells and other materials, seen from the level of violence kerang.The aim of this research to assess the utilization of waste shells as an alternative ameliorant material on peatland. Research conducted at the Faculty of Agriculture, University of Teuku Umar, Meulaboh in June 2014 to December 2014. Analysis of the chemical constituents shells held in Baristand Industry Banda Aceh, parameters observed were peat soil pH before and after being given ameliorant waste shells, Ca compound, Na, P, and Mg and micro nutrients (Fe, Cu, Ni, B, Zn and Si) in 100 grams of waste shells. This study was followed by the application of waste shells on spinach crops as an indicator of plant growth and production parameters were observed. The result of this research shows that the content of Ca as a constituent CaCO3 in mussel shells higher than dolomite. Giving flour shells can raise the pH soils. The giving of 1.9 ton ha-1 shell clams flour showed the growth and yield of spinach were not significantly different from shell clams flour showed or dolomite flour at a dose of 3.8 ton ha-1. Shell clams flour can be used as an alternative material ameliorant replacement dolomite. Keywords: ameliorant, peat, Shells clams, spinach

Abstract

Red chili is one of the most widely cultivated horticultural plants. The problem that is often experienced by chilli farmers is wilting caused by Fusarium oxysporum. This disease attacks plant roots and has the potential to cause damage to almost all plant organs. One of the control of these pathogens that can be done is by utilizing biological control agents such as Pseudomonas sp.. This study aims to determine the effect of using crude extract of Pseudomonassp. in suppressing the onset of wilt caused by Fusarium oxysporum on Chili plants. This study used a non factorial randomized block design with a combination of dose and time of administration of Pseudomonas sp. crude extract. The results showed that variations of Pseudomonas sp. crude extract doses was not caused significant effect on the percentage of attacks and the intensity of Fusarium oxysporum attacks. While the best act for the application ofPseudomonas sp. crude extract is when planting. This is significantly different from the application 7 days before and after planting.Keywords: Fusarium wilt disease, Fusarium oxysporum, Pseudomonas sp., Antagonistic, Red Chili

Abstract

Nutmeg (Myristica fragrans Houtt) is a multipurpose plantation commodity crop that almost all parts of the plant have strategic economic value to be cultivated. In Indonesia there are the largest nutmeg commodity centers, including the Maluku islands, North Sulawesi and Aceh. The biggest problem with nutmeg plants is the attack of pests and diseases. One of the most severe diseases in nutmeg is white root mushroom (Rigidoporus lignosus). This study aims to 1) determine the fungus of white root fungus antagonists (Rigodoporus lignosus) from the Aceh nutmeg rhizosphere (Myristica fragrans Houtt), 2) identify the content of antibiotic fungus JAP antagonist compounds in Aceh nutmeg plants. The study was conducted by taking soil samples from nutmeg plants at three nutmeg plantations in South Aceh. The antagonist fungus isolation activity uses a dilution method. Isolation of JAP from infected roots using direct planting method. Furthermore, it is identified macroscopically and microscopically. The antagonist test was carried out using the dual culture method with RAL. From the rhizosphere in the nutmeg area, 5 candidate antagonist isolates were obtained, having high in vitro antagonism ability to the pathogen R. lignosus. Identification results showed that isolates 1, 2 and 3 were Trichoderma spp, and isolates 4 and 5 were Gliocladium virens.
