Abstract

Serangan jamur patogenik pada buah-buahan dan sayuran merupakan salah satu masalah mendasar yang menyebabkan rendahnya produksi pasca panen di Indonesia. Buah tomat merupakan produk pertanian yang mudah rusak dan sangat rentan mengalami kerusakan mekanis, fisiologis, dan patologis apabila tidak dilakukan penanganan pascapanen yang benar. Hal ini menyebabkan buah tomat dengan mudah terkontaminasi oleh jamur patogen. Penelitian yang telah dilaksanakan pada bulan Maret sampai Mei 2018 ini bertujuan untuk mengidentifikasi jamur yang berasosiasi dengan buah tomat yang dijual pada beberapa pasar tradisional di Kota Kupang dan Kabupaten Kupang. Pengambilan sampel dilakukan di lokasi pedagang buah tomat di empat pasar tradisional yang ada di Kupang yaitu pasar Penfui, pasar Oeba, pasar Inpres Naikoten, dan pasar Oesao. Metode penelitian yang digunakan adalah metode survei di lapangan dan eksperimen di laboratorium. Sampel buah tomat sakit dimasukkan ke dalam plastik sampel, diberi label dan dibawa ke laboratorium untuk pengamatan lebih lanjut dan pengidentifikasian patogen secara makroskopis dan mikroskopis. Pengamatan makrokopis dilakukan untuk mengamati warna dan bentuk koloni, serta kecepatan tumbuh pada cawan Petri. Pengamatan secara mikroskopis dilakukan untuk mengamati persekatan hifa, bentuk dan ukuran konidia, konidiofor, dan tubuh buah lainnya. Data gejala dan tanda patogen pada buah tomat serta identifkasi patogen secara makroskopis dan mikroskopis dianalisis secara deskriptif dan disajikan dalam bentuk gambar yang dibandingkan dengan literatur yang relevan. Hasil penelitian menunjukkan bahwa terdapat tujuh species jamur pascapanen yang berasosiasi dengan buah tomat di pasar, yaitu Aspergillus niger, Aspergillus wentii, Aspergillus flavus, Aspergillus parasiticus, Mucor circinelloides, Fusarium oxysporum, dan Penicillium lanosum.

Abstract

Dryland farming in Timor island is always constrained with the shortage of water supply, soil fertility as well as the availability of nutrients especially Phosphor (P). This condition can be eliminated by application of organic matterial to soil, because organic matter can increase the soil’s ability to hold water and soil fertility. Biochar as an organic material has been proved to increase soil water holding capacity and able to adsorb nutrients to prevent it from leaching. This research aimed to study the effect of combination of biochar and water supply on the availability of P in soil, uptake P by plants and yields of Turnip planted ini calcareous soil of Timor . This research is designed using Completely Randomized Design (CRD) and it is a single factor trial. There are 7 treatments of a combination of rice husk biochar dosage and volume of water supply. The results showed that there is a significant effect of the combination of rice husk biochar dosage and volume of water supply on the availability of soil P and the weight of radish tubers. Application of 300 gram.polybag-1 of biochar + 90% Etm of water supply gave higher available P (87,22 ppm), while application of 300 gram.polybag-1 of biochar + 80% Etm of water supply gave a better fresh weight of tuber (305,00 g ) compare to other treatments.

Abstract

Vertisol is a type of soil that has high in clay content, and generally has low organic matter content and available Nitrogen (N). This condition could be improved by the application of liquid organic fertilizer (LOF). One of the LOF that can be used is LOF made from washing rice waste water and egg shells. A polybag trial was undertaken to evaluate the effect of the application of LOF on some chemical properties of Vertisol and paprika yields (Capsicum annum var. grossum).The research was conducted from July to October 2020. The research was laid out in a Randomized Block Design consisting of 5 treatments namely P0; without LOF, P1; 50 ml LOF, P2; 100 ml LOF, P3; 150 ml LOF, and P4; 200 ml LOF. There were three replicates for each treatment. Data observed were analyzed using Analysis of Variance (ANOVA) followed by 5% DMRT. The observed data included total- N, available P, available K, number of fruit, and fresh weight fruit. The results showed that the application of LOF based on on rice wastewater and egg shell flour could improved soil chemical properties of Vertisols and yield of capsicum. The best treatment was at the application of 200 ml that contributed a good total - N, available P and available K as well as the highest number of fruit and fresh fruit weight of capsicum.

Abstract

To increase edamame production, one of the things to consider is the availability of nutrients, which can be provided through the addition of organic fertilizers, for example, trichocompost. Trichocompost plays a role in increasing crop production because it can increase soil fertility and contains the antagonistic fungus Trichoderma sp., capable of controlling plant pathogens. This study aimed to determine the growth response and yield of edamame due to the dose and time of application of trichocompost fertilizer. This research was carried out at the Undana Archipelago Dry Land Integrated Field Laboratory from October 2020 to June 2021. The study used a factorial randomized block design with two factors. The first factor was the dose of trichocompost (A), which consisted of four levels, namely A1=control, using the recommended NPK dose for edamame, which was 2.4 g/plant, A2=240 g of trichocompost/plant, A3=480 g of trichocompost/ plant, and A4=720 g of trichocompost/plant. The second factor was the application time of trichocompost (B) which consisted of three levels, namely B1 = application of trichocompost two weeks before planting, B2 = application of trichocompost one week before planting, and B3 = application of trichocompost at planting. Parameters observed were plant height, number of leaves, number of pods per plant, number of seeds, fresh plant weight, and seed dry weight. The results showed that the interaction between the doses of trichocompost fertilizer and the application time of trichocompost had no significant effect on all observational parameters. However, there was a tendency that trichocompost at a dose of 720 g/plant applied two weeks before planting had a higher number of pods, seeds, fresh weight, and dry weight of plants compared to the other treatments.

Abstract

Calcarosol merupakan istilah yang merujuk pada tanah-tanah yang terbentuk di atas formasi batuan kapur (limestone). Permasalahan utama yang ditemui dalam kegiatan budidaya jagung di tanah Calcarosol adalah ketersediaan hara fosfor (P) yang rendah. Aplikasi pupuk organik dan pupuk hayati diketahui dapat meningkatkan hara P pada tanah Calcarosol melalui beberapa mekanisme. Penelitian ini dilakukan dengan tujuan untuk menguji keefektifan paket pemupukan organik dan hayati (PPOH) dalam menekan penggunaan pupuk P-anorganik (SP-36) pada Calcarosol di Timor Barat. Penelitian dilaksanakan melalui kegiatan percobaan di lahan milik petani di Kelurahan Penfui, Kecamatan Kelapa Lima Kota Kupang dengan menggunakan rancangan acak lengkap (RAL).  Perlakuan yang dicobakan meliputi: tanpa aplikasi pupuk (P0); PPOH tanpa penambahan pupuk sintetis (P1);  PPOH + 50 kg/ha SP 36 (P2);  PPOH + 100 kg/ha SP-36 (P3); PPOH + 150 kg/ha SP-36 (P4); PPOH + 200 kg/ha SP-36 (P5); dan PPOH + 250 kg/ha (P6). Hasil penelitian menunjukkan: (1) kandungan hara P jaringan tanaman pada perlakuan aplikasi PPOH + 50 kg/ha SP-36  yang tidak berbeda secara signifikan dengan perlakuan PPOH + 250 kg/ha SP-36 membuktikan bahwa dengan aplikasi PPOH, penggunaan pupuk SP-36 dapat dikurangi hingga 80% dari dosis yang umum digunakan oleh petani untuk memenuhi kebutuhan hara P tanaman; (2) bobot biji pipilan kering jagung pada perlakuan PPOH saja yang tidak berbeda secara signikan dengan perlakuan PPOH + 250 kg/ha SP-36 membuktikan bahwa aplikasi PPOH mampu mensubtitusi penggunaan pupuk SP-36 di tanah Calcarosol pada musim tanam pertama pasca aplikasi.

Abstract

Tomato plays an important role in Indonesian agriculture. Tomato production has been constrained by diseases, one of which was bacterial wilt (Ralstonia solanacearum). Application of Vesicular Arbuscular Mycorhiza (VAM) has been reported to be effective in suppressing diseases and can improve plant growth. This study was aimed to test the effect of VAM Glomus sp. in suppressing bacterial wilt disease on tomato (Lycopersicum esculentum). This research was conducted at Plant Disease Laboratory and Screenhouse of Agriculture Faculty, Nusa Cendana University. Seven treatments with three replications were arranged in Randomized Completely Block Design experiment. The treatments were 5 grams, 10 grams, and 15 grams of Glomus sp. per polybag that applied 1-week before pathogen inoculation, and also 5 grams, 10 grams, and 15 grams of Glomus sp. per polybag that applied simultaneously with pathogen inoculation. Control treatment was only inoculated with the pathogen. Three polybags, with two tomato plants planted in each were considered as one experimental unit. Ralstonia solanacearum was isolated from diseased tomato plant. Isolate pathogenicity was confirmed through hypersensitivity test on tobacco plants and on 21 day-old tomato plants. Two-week old tomato plants were inoculated with 15mL of suspension. The stem was punctured with sterile needle pryor inoculation. The result showed that Glomus sp. application before pathogen icoculation lowered disease incidence significantly. Application of 15 grams Glomus sp. before pathogen inoculation caused the greatest mycorrhizal vesicle formation in tomato root, which might also increased plant height and the number of leaves significantly.

Abstract

Phosphorus (P) is an essential nutrient for plants. Most of the P in the soil is fixed to soil minerals resulting in insolubility and unavailability of the nutrient to plants. One alternative to overcome this problem is the use of Phosphate Solubilizing Bacteria (PSB). This research was carried out in the Plant Disease Laboratory and Soil Chemistry Laboratory, Faculty of Agriculture, Nusa Cendana University from September 2022 to March 2023. The aims of this research were to investigate the occurrence and diversity of PSB isolates collected from the soil of agricultural land coastal ecosystems Kupang, and to determine their ability to solubilize P. At each ecosystem, five soil samples were taken from the rhizosphere of different plants growing in that ecosystem for PSB isolation and soil analysis. Isolation of PSB was based on pour plate method. The growing isolates were purified, calculated for the PSI and then characterized both macroscopically and microscopically. For morphology characterization of PSB (gram properties and cell shape) gram staining techniques was applied. The results showed that a number of PSB isolates, characterized by the formation of clear zone around the colony of bacteria, was obtained from the rhizosphere of plants from the coastal and agricultural land ecosystems accounted for 16 and 9 isolates respectively. The isolates obtained differed in the morphological characteristics and phosphate solubilizing index (PSI) with the PSI value ranged 2.25- 3 for isolates from agricultural land, and 2,14- 4 for isolates from coastal ecosystem. In the future, the isolates obtained from this study need to be further identified and introduced to plants to evaluate their ability to improve plant acquisition of phosphorus.

Abstract

An experimental research was carried out on farmer's land in Batuplat Village, Alak District, Kupang City and at the Soil Physics Laboratory, Faculty of Agriculture, Nusa Cendana University. The aims of this study were: (1) to determine the effect of the treatment of the composition of the planting medium in the form of a mixture of vertisol, sand and rice husk charcoal on the physical properties of the soil, growth and yield of rapeseed; and (2) getting the composition of the growing media that gives the best effect on soil physical properties, growth, and radish yield. The study was designed in a single factor experiment using an environmental design in the form of a completely randomized design (CRD). The treatment tested was the composition of the planting medium in the form of a mixture of vertisol, sand and rice husk charcoal, namely: 1 : 1 : 1 (P1); 1 : 1 : 2 (P2); 1 : 2 : 1 (P3); 2 : 1 : 1 (P4); 2 : 2 : 1 (P5) and 2 : 1 : 2 (P6). Each treatment was made in 3 replications so that in total there were 18 experimental units. Parameters observed included: soil bulk density, soil porosity, plant height, number of leaves per plant, and fresh weight of radish tubers. The results showed: (1) the composition of the growing media had a very significant effect on the parameters of fill density and soil porosity, as well as the height and number of leaves per plant at the age of 2 and 4 weeks after planting (MST), but had no significant effect on the fresh weight of radish tubers per plant; (2) there was no treatment of the composition of the planting medium in the form of a mixture of Vertisol, soil, and rice husk charcoal which had the best effect on the physical properties of the soil, growth and yield of rapeseed. Each treatment of the composition of the planting media that was tried was able to change the physical condition of the Vertisols to be better and more conducive to plant growth and development of radish tubers in the soil.
