Abstract

Arbuscular mycorrhizal fungi are a group of fungi that can be symbiotic with many types of plants. Soil factors and plant species, affect the diversity of arbuscular mycorrhizal fungi. Likewise, differences in location and rhizosphere cause differences in the diversity of species and populations of AMF. In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. Coffee is a plant that has economic value and the potential for symbiosis with AMF. This study aimed to identify AMF in the rhizosphere of four varieties of Solok Radjo coffee plants in the Aia Cold area of ​​the Gumanti Valley, Solok, West Sumatra. Meanwhile, the stages of this research include: collecting and collecting data in the field, determining the location of the soil sample, analyzing soil properties in the laboratory, isolating AMF spores, and identifying AMF spores morphologically. The results showed that the diversity of AMF spores was found in 3 genera, namely Glomus sp., Acaulospora sp., and Gigaspora sp. The Kartika coffee variety has a higher AMF spore population than Sigararutang, Andongsari and Gayo.

Abstract

The widespread use of mutagenesis for plant genetic improvement can be explained by a number of factors, including the fact that new varieties can be developed in a shorter time than conventional breeding methods and that transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens that are often used in plant mutagenesis techniques and are safe for human health because there is no environmental risk in the induced generations. The method used in this paper is by grouping articles according to their relevance to the subject and year of research, and finally managing the explanatory structure. Journal articles for the period 2012 to 2022 were searched using keywords: breeding, mutation, mutagen, rice, and gamma iridation. The selection of selected articles comes from the PubMed, Elsevier, and Springer web sites. This paper integrates the available data on the effects of mutation breeding of plant varieties in different countries and addresses the potential of gamma irrigation as a flexible and practical approach that can be applied to rice crops and an appropriate selection method.

Abstract

Indonesia dikenal sebagai wilayah megabiodiversity, hal ini disebabkan karena menyimpan keanekaragaman spesies flora serta fauna yang melimpah. Kuantitas dari biodiversitas ini bersifat fluktuatif, kenaikan terjadi jika ditemukan spesies-spesies baru di alam, dan penurunan bisa disebabkan akibat terjadinya kepunahan. Sumatera Barat merupakan daerah dengan tingkat sumber keanekaragaman hayati yang tinggi. Namun sampai saat ini potret biodiversitas provinsi Sumatera Barat tidak dideskripsikan secara menyeluruh dan lengkap, tercatat belum semua daerah memiliki basis data kanekaragaman hayati. Salah satu pangan lokal alternatif yang belum teridentifikasi secara menyeluruh ialah tanaman hanjeli dengan nama ilmiah Coix lacrima-jobi L. Tujuan dari review artikel ini yakni untuk mengumpulkan informasi-informasi perihal kondisi keanekaragaman tanaman hanjeli yang ada di Sumatera Barat. Ditemukan bahwa hanjeli mampu untuk tumbuh pada dataran rendah hingga dataran tinggi serta mampu adaptif pada bermacam kondisi ekosistem, antara lain pada lahan kering serta zona di sekitar sumber aliran air. Diketahui bahwa terdapat keanekaragaman tanaman hanjeli yang ditemukan di provinsi Sumatera Barat, hal ini terlihat dari keragaman fenotipik yang ditampilkan baik berupa karakter kualitatif maupun kuantitif pada batang, daun, bunga, serta biji.

Abstract

Utilizing idle land as agricultural land is one option that can be pursued to support national food security and independence. Indonesia has various types of alternative food commodities that have the potential to be developed on nutrient-poor land, one of which is hanjeli. Technical cultivation is needed to increase the growth and yield of hanjeli on sub-optimal land. This study aims to determine the best planting distance to increase hanjeli production on idle land. The research was conducted from October 2020 - March 2021 in Limau Manis, Padang City, West Sumatra. The materials used in this study were rice cultivar hanjeli seeds, manure (20 tons/ha) and NPK fertilizer (200 kg/ha). The experimental design used was Randomized Group Design with 3 groups and consisted of 8 plant spacing treatments (40 x 40 cm, 50 x 40 cm, 50 x 50, 50 x 60 cm, 50 x 70 cm, 50 x 80 cm, 50 x 90 cm, and 50 x 100 cm). Observation data were analyzed statistically to determine the influential treatment using the F test at the 5% level and significantly different data were tested using the Duncan’s Multiple Range Test at the 5% level. It was concluded that the spacing of 50 x 70 cm, 50 x 80 cm, 50 x 90 cm and 50 x 100 cm gave the best effect on the number of total tillers/plant, the number of productive tillers/plant, the number of seeds/plant, the percentage of filled seeds, the weight of filled seeds/plant. As for productivity, the spacing of 50 x 80 cm gave the best results.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.
