Abstract

Ishaq L. 2018. Short Communication: Presence of arbuscular mycorrhiza in maize plantation land cultivated with traditional and improved land management.Trop Drylands 2: 20-24. Arbuscular mycorrhizas (AM) are one of key fungtional soil biota that can greatly contribute to crop productiviy and agricultural sustainability. Their presences could be influenced by soil condition such as land management, and the sporulation of the fungal forming mycorrhiza could be affected by season ie. rainy and dry season. Previously, it was found that the abundance of AM fungi was higher under maize cropping with traditional land management (no tillage, no input of agrochemicals) than that under maize copping system with more modern land management (tillage, agrochemical input), when the soils were sampled at rainy season. As the presence of AM fungi could be influenced by climate factor ie. rain/season, the present study was carried out to examine the abundance and diversity of AM fungi in maize plantation land cultivated with traditional and improved land management in the dry season. At each land management system, three locations of study were purposively selected, and at each location within the cropping system, three soil samples were collected. A total of 9 soil samples representing each land management system were evaluated. The variables observed included AM fungal spore density (expressed as the number of AM fungal spores per 100 g of soil) and biodiversity of AM fungi (expressed as relative abundance of AM fungal spore). It was found that the density of AM fungal spore under maize cropping system with traditional land management was 203.55 per 100g, whereas only 84.91 spores per 100 g soil were found under maize cropping system with improved land management, supporting the previous finding. Despite only six AM fungal spores morphotypes were observed under maize plantation land of both traditional and improved land management, the abundance of the morphotype was different between the two land management systems. The study needs to be extended at a broader location and time to get more representative information on the impact of land management on the abundance of AM fungi in tropical agriculture.

Abstract

Kesuburan tanah yang rendah menjadi salah satu faktor pembatas rendahnya produksi jagung di Pulau Timor. Hal ini terutama terkait dengan ketersediaan unsur hara fosfor (P) yang rendah yang umumnya diatasi oleh petani melalui penggunaan pupuk P-anorganik. Namun demikian, kondisi tanah yang berkapur dapat menurunkan ketersediaan hara P bagi tanaman sehingga pupuk P-anorganik memiliki efisiensi yang rendah. Tujuan penelitian ini untuk mendapatkan dosis pupuk fosfor (P) anorganik dan inokulasi kelompok FMA yang memberikan pengaruh terbaik terhadap serapan hara P, pertumbuhan dan hasil tanaman jagung. Penelitian dilaksanakan di lahan pertanian di Desa Penfui Timur, Kabupaten Kupang dan Laboratorium Fisika dan Kimia Tanah Fakultas Pertanian Universitas Nusa Cendana Kupang. Penelitian ini dirancang dalam percobaan faktorial 2 faktor menggunakan rancangan lingkungan berupa rancangan petak terpisah (spit plot design) dengan 3 ulangan. Petak utama adalah inokulasi FMA (M) yang terdiri dari 3 taraf: tanpa inokulasi FMA (M0), inokulasi satu jenis spora FMA (M1), dan inokulasi spora FMA campuran (M2). Anak petak adalah dosis pupuk P (SP-36) (P) yang terdiri dari 4 taraf: 25% (P1), 50% (P2), 75% (P3), dan 100% (P4) dosis anjuran. Variabel yang diamati adalah kandungan hara P-jaringan tanaman, tinggi tanaman dan bobot 100 butir jagung pipilan kering. Hasil penelitian menunjukkan: (1) interaksi perlakuan inokulasi FMA dengan perlakuan dosis pupuk P-anorganik tidak berpengaruh nyata terhadap semua variabel pengamatan; perlakuan tunggal inokulasi FMA berpengaruh nyata terhadap tinggi tanaman dan bobot 100 butir jagung pipilan kering namun tidak berpengaruh nyata terhadap kandungan hara P jaringan tanaman; perlakuan tunggal dosis pupuk P-anorganik hanya berpengaruh nyata terhadap kandungan hara P-jaringan tanaman namun tidak berpengaruh nyata terhadap tinggi tanaman dan bobot 100 butir jagung pipilan kering, (2) inokulasi FMA baik tipe spora tunggal maupun tipe spora campuran belum mampu meningkatkan kandungan hara P jaringan tanaman namun mampu meningkatkan tinggi tanaman dan bobot 100 butir jagung pipilan kering; tidak terdapat perbedaan nyata antara perlakuan inokulasi FMA tipe spora tunggal dengan perlakuan tipe spora campuran dalam meningkatkan tinggi tanaman dan bobot 100 butir jagung pipilan kering sehingga tidak didapatkan perlakuan inokulasi FMA terbaik dalam penelitian ini, dan (3) tidak didapatkan perlakuan dosis pupuk P-anorganik yang memberikan pengaruh terbaik dalam meningkatkan serapan hara P, pertumbuhan, dan hasil tanaman jagung pada penelitian ini berkaitan dengan efisiensi pemupukan P-anorganik yang rendah pada lahan berkapur.

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

Produktivitas sayuran di Desa Baumata Kabupaten Kupang relatif rendah akibat rendahnya kesuburan tanah. Upaya peningkatan kesuburan tanah melalui aplikasi pupuk anorganik terkendala oleh efisiensi pemupukan anorganik yang rendah dan seringnya terjadi kelangkaan pupuk di pasaran. Menyikapi kondisi tersebut, aplikasi pupuk organik seperti bokashi plus dan eco-enzym dapat menjadi alternatif untuk memenuhi kebutuhan pupuk di tingkat petani. Untuk itu, petani perlu dibekali dengan pengetahuan dan keterampilan tentang pembuatan dan aplikasi bokashi plus dan eco-enzym. Program Pengabdian pada Masyarakat (PPM) ini digagas oleh kelompok dosen Program Studi Agroteknologi, Fakultas Pertanian, Universitas Nusa Cendana, dengan tujuan: (1) meningkatkan kemandirian mitra dalam memenuhi kebutuhan pupuk dengan memanfaatkan limbah organik; dan (2) meningkatkan keterampilan mitra dalam mengolah bahan organik menjadi bokashi plus dan eco-enzym. Sasaran program PPM ini adalah 10 anggota kelompok tani Manekan di Desa Baumata, Kecamatan Taebenu, Kabupaten Kupang. Metode pendekatan yang digunakan dalam program ini adalah transfer informasi dan alih teknologi, melalui: (1) kegiatan pelatihan pengolahan bahan organik menjadi bokashi plus dan eco-enzym dan; (2) demplot aplikasi bokashi plus dan eco-enzym pada budidaya sayuran. Pelaksanaan Program PPM ini berjalan sesuai target yang ditetapkan dengan tingkat partisipasi anggota kelompok mitra sebesar 100%. Setelah mengikuti program PPM ini, seluruh anggota kelompok mitra mampu membuat bokashi plus dan eco-enzym secara mandiri dan berminat untuk menerapkannya pada usaha tani sayuran yang digelutinya saat ini.

Abstract

The use of phosphate-solubilizing microorganisms combined with chemical fertilizers is very important, especially in soils that contain a lot of calcium. This is due to orthophosphate ions easily bind to calcium and these microorganisms are able to dissolve the fixed phosphate. The research has been conducted at the Faperta Undana experimental garden and took place from June 2023 to February 2024. The purpose of this study was to determine the interaction between phosphate-solubilizing bacteria (PSB) inoculation and phospahate fertilizer on the availability of P, population of PSB, fertilization efficiency and yield of glutinous corn, and to identify the combination that give the best result on the variables observed. The study was designed using a Completely Randomized Design. The first factor was PSB inoculation that consists of : without PSB inoculation and indigenous PSB inoculation. The second factor was the dose of P fertilizer with five levels as follows: 0%, 25%, 50%, 75%, and 100%. Data were analyzed using analysis of variance, followed by the Duncan Multiple Range Test if significant effects were found. Observed variables included PSB population, available P, fertilization efficiency, weight of corn without husks. The results showed that the interaction between PSB inoculation and the dose of SP-36 fertilizer had a significant effect only on fertilization efficiency. The single factor of PSB inoculation significantly affected the availability of P and PSB population, while the single factor of SP-36 fertilizer dose significantly affected fertilization efficiency, available P, and corn weight per cob without husks.

Abstract

The study was conducted in three different ecosystems: mamar (a typical local ecosystem close to water catchment areas), farm, and coastal ecosystems. In each ecosystem, soil samples were taken from the rhizosphere of five different plants to investigate the occurrence of PSM, molecularly identify the potential isolates, and evaluate their ability to increase soil phosphorus (P) availability and mungbean yield. The highest population of phosphate-solubilizing bacteria (PSB) was found in the mamar ecosystem. Phosphate-solubilizing fungi were only found in the farm and coastal ecosystems, with low populations, and restricted to the rhizosphere of a few plants. The number of PSB isolates was higher in the coastal ecosystem, followed by the farm and mamar ecosystems. The phosphate solubilizing index of the isolate was quite high, ranging from 210 to 300. One isolate from the five molecularly selected isolates from Kupang regency was identified as Aspergillus sp. (cassava rhizosphere origin), one isolate from the farm ecosystem (Moringa rhizosphere origin), and three isolates from the coastal ecosystem (Jatropha gossypiifolioa, Scheichera oleosa and Calotropis gigantea L. rhizosphere origin) were all identified as Pseudomonas sp. Two selected isolates from a previous study in Timor Tengah Selatan regency, collected from the mamar ecosystem (bamboo and Leuchaena leucocephala rhizosphere), were both identified as Acinetobacter baumannii. Inoculation of PSB resulted in higher available soil P compared to the uninoculated treatment. PSB inoculation also provided higher tissue P than the uninoculated treatment. PSB from coastal areas gave the highest pod weight and seed weight compared to other inoculation treatments.
