Abstract

This study was aimed at assessing effects of mulch on soil temperature, physical properties of soil, and growth of patchouli. The experiment was conducted in Village ReuleutTimu, Sub District MuaraBatu, District Aceh Utara, from June to September 2013. The experiment was arranged in a randomized block design with three replicates. Types of mulching consisted of five levels i.e. without mulching, rice straw spread 10 tons ha-1, rice straw mulch spread 5 ton ha-1 + embedded 5 ton ha-1, sawdust spread 10 tons ha-1, sawdust spread 5 ton ha-1 + embedded 5 ton ha-1.The variables observed were soil temperature, bulk density, C-organic, N-total, C/N ratio, porosity of the soil, plant height, number of branches, leaf area, and dry weight of plants. Results showed that mulching resulted in lowering temperature, value of bulkdensity, and ratio of C/N soil, andincreasing levels of N-total, and improving soil porosity.  Mulching also affected plant height, number of branches, leaf area, and plant dry weight. Rice straw provided lower degree of soil temperatures than sawdust, but did not provide better of plant height, number of leaves, leaf area and dry weight of plants. Spread rice straw provided lower soil temperature and better leaf area at 60 day after planting but lesser dry weight at 75 day after plantingthan spread+embedded rice straw.

Abstract

The objectives of this research were to assess effects of varieties and hydrocarbon-contaminated growing medium on seed vigors of corn and interactions between the two factors mentioned. The experimental design used was a completely randomized design 3 x 4 with three replications. The first factor was varieties, consisting three varieties, namely, Pertiwi 3, Manise, and Bonanza F1.  The second factor was hydrocarbon-contaminated growing medium, consisting four levels of  hydrocarbon (crude oil) concentration i.e. without crude oil,  5 ml crude oil/liter water,  10 ml crude oil/liter water  and  15 ml crude oil/liter water.  The result showed that some varieties significantly affect potential of seed growth, seed germination, rate of germination, vigor index and seed germination uniformity. However, concentration of hydrocarbon did not significantly affect all parameter observed.  There was significant interaction between varieties and concentration of hydrocarbon on potential of seed growth, seed germination uniformity and T.50.

Abstract

Screening genotypes of Aceh cacao to obtain resistant genotypes to Black Pod Disease (Phytopthora palmivora) is a key step. This study was conducted on basis of screening natural infection in the field and artificial infection in laboratory. The research was conducted in the field (Saree Aceh and East Aceh) and in the Plant Pathology Laboratory, Agriculture Faculty, Syiah Kuala University. The study started from March to November 2013. Results from the field and laboratory, based on artificial inoculation, showed that three genotypes originated from Saree Aceh i.e. SR 26, SR 40 and SR7 were resistant, indicated by the characters of long incubation period (more than five days), a small diameter of spot, slow growth of the spot, and low percentage of symptoms. The three genotypes had both a good wounded post-penetration and unwounded pre-penetration resistance. Conversely, cacao genotypes originated from East Aceh did not show a significant difference of post-penetration resistance.

Abstract

The diversity of phenotypic characters of several soybean varieties were evaluated in the area of North Aceh. The study was aimed at determining the phenotypic diversity of several varieties of soybean in North Aceh. The experiment was arranged in a non-factorial randomized complete block design. Varieties consisted of six varieties of soybean, namely Kipas Merah, Gamasugen 1, Muria, Mitani, Rajabasa dan Mutiara 1. Data were analyzed using analysis of variance and followed by Least Significant Difference Test. Results showed that variety exerted high significant effect on the characters of a number of branches, number of pods, number of seeds per plant, seed weight per plant, weight of 100 grains, and grain weight per plot, but did not significantly affect plant height at 2, 3, 4, 5 week after planting and height at harvest.  The highest heritability values was found at a weight of 100 seeds (0.95) and the lowest at plant height (0.28).  Mutiara 1 can be used as an alternative for farmers besides Kipas Merah, because Mutiara 1 produced a high yield and had the largest seed.

Abstract

The aim of this research was to investigate effects of Arbuscular Mycorrhizal Fungi and compost on soil chemical properties under soybean.  The research was conducted in Ude Village, Matangkuli Sub-District, Aceh Utara District, from June to November 2013.  The experimental design was a factorial randomized complete block design with three replications. The first factor was Arbuscular Mycorrhizal Fungi doses, consisted of 4 levels: 0, 20, 40, and 60 g Pot-1. The second factor was compost doses, consisted of 4 levels: 0, 75, 150, and 225 g Pot-1. Variables measured were pH value, available P, and organic C soil. The results showed that compost doses gave significantly effect on pH value, available P and C-organic soil.  Arbuscular Mycorrhizal Fungi doses increased the pH value, available P and organic C compared to without the fungi. There was a significant interaction between Arbuscular Mycorrhizal Fungi doses and compost doses on pH value and available P. Arbuscular Mycorrhizal Fungi dose of 60 g pot -1 and compost dose of 150 g pot-1 was able to increase the pH value. However, the best available P was found at Arbuscular Mycorrhizal Fungi dose of 60 g pot-1 and compost dose of 75 g pot-1.

Abstract

An effort to anticipate a food crisis is to increase food production by planting upland rice in dry lands. In addition, provision of appropriate fertilizer has great potential for strengthening food self-sufficiency and for future agricultural development. The study was aimed at determining growth and yield of three varieties of upland rice under a compound fertilizer. The experiment was arranged in split plot design, consisting of three upland rice varieties and three levels of compound fertilizer. The main plot was upland rice varieties, i.e. Inpago 4, Inpago 5, and Inpago 8, while the subplot was compound fertilizer, i.e. a dose of 0 kg/ha, 150 kg/ha, and 250 kg/ha. Results showed that varieties significantly affected plant height, panicle numbers, and panicle length, but did not significant affect weight of 1000 grains and dried grain. Inpago 4 was the best variety. The best of NPK fertilizer was found at dose of 250 kg/ha.

Abstract

This study was aimed at determining type of organic material suitable for the growth and yield of two varieties of tomatoes and the interaction between the two factors. This experiment was conducted at the experimental field of the Agriculture Faculty, Syiah Kuala University, Darussalam, Banda Aceh. The experiment was arranged in a randomized complete block design, 4 x 2 with three replications. There were two factors investigated: organic material consisting 4 levels (control, manure, compost peat, and compost), varieties consisting two levels (Permata and Lentana F1). Variables observed were height and stem diameter, fruit weight per plant, number of fruits per plant, number of bunches per plant, number of fruits per bunch, average weight per fruit and yield potential. The results showed that the type of organic material highly significantly affected plant height and stem diameter at the ages of 30 and 45 days after planting, fruit weight per plant, number of fruits per plant, and significantly affected plant height at the age of 15 HST but did not significantly affect the number of bunches per plant, number of fruits per bunch, average weight per fruit and yield potential. Growth and yield were better at manure compared to compost, peat compost, and control. Varieties significantly affected stem diameter at the age of 15, 30 and 45 days after planting, fruit weight per plant, number of fruits per plant, number of bunches per plant, number of fruits per bunch, average weight per fruit and potential results. Growth and yield were better found in varieties Permata. There were significant interactions between types of organic materials and varieties in all observed variables on growth and yield of tomato.

Abstract

Effects of fertilization on growth of several varieties of upland rice have been studied.  The experiment was arranged in a randomized complete block design, 3 x 4 factorial design with three replications. Factors studied were fertilization i.e. 100% compost, 100% inorganic fertilizers, and mixture of 50% organic and inorganic fertilizers. Upland rice varieties consisted of Cirata, Limboto, Situ Bagendit, and Situ Patenggang. Results showed that mixture of 50% organic and inorganic was the best on plant height at  ages of 2, 3, 4, 5, 6, 7, 8 and 9 week after planting (WAP) and tiller numbers per hill. Meanwhile, 100% organic fertilizer was the best for flowering and harvesting ages. The best variety for plant height was Cirata and Situ Patenggang, while for tiller numbers was Situ Bagendit. There were interactions between fertilization and variety on plant height and tiller numbers.  The best combination for plant height was Situ Patenggang and mixture of 50% organic and inorganic, while for tiller numbers was Situ Bagendit and mixture of 50% organic and inorganic.

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

High dependence of rice farming on chemical fertilizers has an adverse impact on environment and the economy. Thus, it is necessary to develop varieties that are tolerant to low nutrient conditions. This experiment was arranged in a randomized block design with a total sample of 88 plants. The results showed that grain weight per panicle was the variable that has the highest diversity, followed by the number of leaf chlorosis per productive tillers and number of panicles. Plant height was a variable that has the lowest diversity. Moreover, the number of panicles showed significant positive skewness, which indicates that the number of panicles have complementary gene interaction. Plant height, number of leaf chlorosis per productive tiller, and number of panicles had positive kurtosis values, which indicate that these variables are controlled by a few genes. In contrast, grain weight per panicle, number of tillers, and the number of leaves had negative kurtosis values, which indicate that these variables are controlled by many genes. F4 bulk population gave 32 clusters, which indicate that this F4 population has a high variation among individuals.
