Abstract

        The study was aimed at determining responses of several sweet corn varieties to organic and inorganic fertilizers on tsunami affected land and knowing interactions between both factors on growth and yield of sweet corn. The experiment was conducted in Village of Lampuuk, Lhoknga, District of Aceh Besar, from January 7 to March 19, 2008. This research was conducted using a randomized complete block design (RCBD), 3 x 3 with 3 replications. There were two factors studied, namely fertilizations, consisting of 3 levels: 100% organic fertilizer, 50% organic fertilizer + 50% inorganic fertilizers and 100% inorganic fertilizers. The second factor was varieties, consisting of 3 levels: Sweet Boy, Hawaiian Sweet Corn Hybrid F1 and Super Bee. The results showed that fertilization significantly affected ear weight with and without cornhusk, but did not affect diameter of ear and seed rows per ear. The highest result was found at a treatment of 50% organic fertilizer + 50% inorganic fertilizers, but was not significantly different from 100% organic fertilizer. Varieties showed no significant effects on all variables observed.  There were significant interactions between fertilizations and varieties on plant height at age 42 and 63 day after planting (DAP), leaf length at age 21, 42, and 63 DAP, and root fresh weight at age 21 DAP.  The best plant growth was found at a combination of Sweet Boy   and 50% organic fertilizer + 50% inorganic fertilizer.

Abstract

The research objectives were to study relationships between soybean seed vigor in laboratory and seed growth in field.  The research was carried out in Laboratory Seed Science and Technology and Seed Experimental Farm of Agriculture Faculty, University of Syiah Kuala, Darussalam Banda Aceh. Experimental design used was a completely randomized design (CRD) 2x5 with 3 replications in the laboratory and a split plot design with 3 replications in the field. The factors examined were soybean varieties and oxygen. The varieties were consisted of Pandermau S-37, Local of Bireuen, Wilis, Orba, local of Tasikmalaya. The oxygen was consisted of 2 levels, i.e. oxygen stress and normal oxygen. Variables observed in the laboratory were seedling growth rate and dry weight of normal seedling, while in the field were soybean growth rate and dry weight of plant.  Results showed that growth of the five varieties on the field of oxygen stress can be simulated through examination in laboratory. Of the two variables observed, seedling growth rate was more sensitive for the purpose. On the other hand, dry weight of seedling was less precise for simulating that condition.

Abstract

The study was aimed at determining appropriate varieties and growing media on growth and yield of red peppers as well as interactions between the two factors mentioned. The experimental design used was a completely randomized design (CRD) 3 x 3 with three replications. Factors studied were red pepper varieties (TM 999, ST 168 and local), and growing media (soil + sand, soil + manure, and soil + husk) with a ratio of 2:1. The results showed that varieties exerted highly significant effects on plant height at 15 days after transplanting (DAT) and fruit weight per plant at first harvest 90 DAT and a significant effect on number of fruits per plant at first harvest 90 DAT. Varieties of TM 999 and ST 168 were better than that of local. Growing media also exerted highly significant effects on plant height at 45 DAT, number of productive branches, number of fruits per plant at first harvest (90 DAT) and fruit weight per plant at first harvest (90 DAT), and significant effects on plant height at 15 and 30 DAT, number of fruits per plant at second harvest (93 DAT), and weight of fruit per plant at third harvest (96 DAT). The best growing medium was soil + sand. There was no significant interaction between varieties and growing media on growth and yield of red chili.

Abstract

The objective of the research was to study effects of drying temperatures (sun drying, 50°C, and 60°C) on quality of dried rosella. Moisture content analysis showed that there were not significantly different among all treatments. However, antocianin and vitamin C content were significantly different in all treatments, and the best drying temperature was 50°C. The brightest color of dried rosella was produced by sun drying.  However, all treatments were browning due to Millard reaction.

Abstract

            Penyakit pasca panen yang disebabkan oleh mikroba menyebabkan kerugian yang sangat besar setiap tahunnya. Pada pertanian konvensional, fungisida sudah digunakan selama bertahun-tahun untuk mengendalikan patogen pada tanaman. Sebagaimana telah diketahui, penggunaan bahan kimia secara terus menerus dapat berdampak buruk terhadap lingkungan dan menyebabkan resistensi.  Ozon telah dianjurkan oleh para ahli  sebagai alternatif pengendalian penggunaan bahan sintetik pada pengawetan bahan makanan karena ozon tidak meninggalkan residu pada bahan simpanan sehingga lebih aman untuk dikonsumsi.           Penelitian ini bertujuan ini untuk mengetahui pengaruh ozon pada konsentrasi rendah (180 ppb) terhadap perkembangan koloni dan spora yang dihasilkan oleh Botrytis aclada secara in vitro. Dua tipe inokulum digunakan pada penelitian ini adalah miselia dan spora.  Keduanya merupakan penyebab kerusakan pada bahan simpanan. Jamur yang diuji disimpan di dalam kotak yang dialiri ozon dengan suhu 7-8oC selama 14 hari. Pengamatan terhadap perkembangan koloni dilakukan dengan mengukur diameter koloni, sementara spora yang dihasilkan diamati pada hari ke 14 masa inkubasi. Hasil penelitian menunjukkan bahwa pemaparan ozon pada konsentrasi 180 ppb selama 14 hari tidak menurunkan perkembangan koloni  B. aclada, tetapi efektif mengurangi jumlah spora yang dihasilkan.

Abstract

The objectives of this study were to investigate several media and liquid organic fertilizer on the growth and the yield of mushroom (Volvariella Volvaceae L) and also to identify the interactions between the two factors. The research was conducted at Lee Guna Gampong Peurada Banda Aceh from 15 June to 23 July 2010.  A factorial randomized completely design with three replications was used in this experiment. The first factor evaluated was medium (dried rice stalks, cane bagasse, and cardboard), and the second factor was Super A-1 fertilizer concentrations (0 cc, 7.5, and 15 cc/L). The results showed that media significantly affected stem weight and cap diameter of mushroom. However, the media did not influence primordial initiation, the number of mushrooms, length and diameter of stems. Mushrooms grew best on the medium of cane bagasse. Super A-1 concentration significantly influenced the number of mushrooms, diameter of mushroom cap, and stem diameter, but did not affect mushroom weight. The best concentration of Super A-1 for mushrooms growth was 15cc/L. There were no interactions between the media and concentration Super A-1 based on variables observed in this experiment.

Abstract

The objectives of the research were to determine effectiveness of antagonist T. harzianum and fungi micorrhyze in suppressing growth of Fusarium oxysporum on tomato. The research used a factorial completely randomized design, consisting of sixteen combination treatments and three replications. The first factor was doses of T. harzianum, consisting of four levels, i.e. 0, 15, 30, and 45 g.polybag-1.  The second factor was doses of micorrhyze, also consisting of four levels, i.e. 0, 5, 10, and 15 g.polybag-1. Variables observe were incubation period, length of xylem discoloration and percentage of wilting plant. The data were analyzed statistically by analysis of variance. The least significant difference test (LSD) at the 0.05 level was used to see the difference between the treatments. The results showed that applications of fungi mycorhize and T. harzianum affected growth of F. Oxysporum f sp. Lycopersici. The incubation period of F. oxysporum on tomato was longer, 20.5 days when applied with mycorrhize 15 g.polybag-1 and T. harzianum 45 g.polybag-1 compared to control 17.75 days. The length of xylem discoloration was only 2.39 cm when treated with FMA 15 g.polybag-1 compared to control 13.44 cm, while xylem discoloration was 6.56 cm when applied with T. harzianum 45 g.polybag-1 compared to control 8.65 cm. Application of mycorrhize 15 g.polybag-1 and T. harzianum 45 g.polybag-1 caused  a decreased percentage of wilting plant. The percentage of wilting plant was 35 % when treated with FMA 15 g.polybag-1 compared to control 74.28% and 42.50% when treated with T. harzianum 45 g.polybag-1 compared to control 54.64%. There was no interaction between fungi mycorrhize and T. harzianum for xylem discoloration and percentage of wilting plant.

Abstract

This study was aimed at determining effects of soil surface treatments and organic matter types, as well as interactions between the two treatments on growth of cayenne pepper. The results showed that there were significant interactions between soil surface treatments and organic material types on plant growth of cayenne pepper at age of 5 weeks after planting.  Surface treatments affected plant growth However, the soil surface treatments were influenced by types of organic matters given in the soil.  On organic matter in the form of compost, the best growth was found on recycled newspaper mulch placed on soil surface. Conversely, on organic matter in the form of pieces of recycled newspaper, mulch of recycled newspapers gave the worst growth.  Organic matters also affected plant growth. However, treatment of organic matter was also influenced by soil surface treatments. On the surface soil compaction treatment, the best growth was obtained at compost. On treatment of newspaper mulch, the best growth was also obtained at the type of compost. In contrast, on the untreated soil surface, the best growth was found at the type of organic matter made of the pieces of recycled newspaper.

Abstract

            This study was aimed at obtaining an effective dose and application timing of Trichoderma in controlling wilt disease caused by Sclerotium on soybean. This study used a factorial complete ramdomized design with 8 combination of treatments and 4 replications. There were two factors studied, dose and timing of Trichoderma. Four level doses factor were studied, i.e. 75, 150, 225, and 300 g.polybag-1, while timing of application consisted of 2 levels, 7 days before planting and at the planting time. The observed variables were germination rate, incubation period, length of lesion formed on the base of the stem, and dry weight of seeds per plant. Data of variables observed was analized by analysis of variance and followed by least significance different test at level 5%.  The results showed that dose of Trichoderma gave a significant effect on seed germination rate, incubation period, length of lesion and dry weight of seed per plant. Dose of Trichoderma 300 g.polibag-1 was the best and gave  germination rate of seed up to 84,38%, incubation period 8 days, length of lesion 1,35 cm and dry weight of seed 24,13 g. The timing of application gave a significant effect only on dry weight of seed per plant.  The best timing of application was found at 7days before planting and no interaction between doses and time of application of Trichoderma.
