Shallot is one of the important vegetables and spices in Indonesia. Shallot require porous soil structure with medium to coarse texture, have good aeration and drainage, containing organic matter, with an optimum soil pH of 5.6 -6.5. This research aimed to examine growth characteristics of shallot on various planting media compositions. An experimental field and laboratory of plant physiology, Department of Agronomy, Sriwijaya University. The research was conducted at from August to November 2017. The experiment was arranged in a randomized block design with 11 treatments and 3 replications. Each unit treatment consisted of 5 plants, resulting in a total of 165 plants. The treatments was media

Abstract. Sefrila M, Ghulamahdi M, Purwono Melati M, Mansur I. 2021. Diversity and abundance of arbuscular fungi mycorrhizal (AMF) in rhizosphere Zea mays in tidal swamp. Biodiversitas 22: 5071-5076. This study aims to find out the diversity and dominance of AMF spores and look at the morphology of fungi mycorrhizal arbuscular fungi that exist in the rooting area of corn (Zea mays L.) crops in the tidal swamp. The study was conducted in September 2020. Soil sampling at the tidal swamp village of Mulyasari Tanjung Lago District, Banyuasin, South Sumatra, Indonesia randomly sampling the corn root zone method. The research stages are soil sampling, soil chemistry analysis, AMF isolation and trapping, and morphological identification of AMF spores. The results showed the number of spores found in soil samples in the corn crop rhizosphere before trapping was less when compared to after trapping. The spores' shape is round, oblong, and oval, with colors ranging from clear, yellow, to brown. AMF spores found come from 2 genera namely (Acaulospora scrobiculata, A. bireticulata, A. mellea, A. laevis) and Glomus (Glomus monosporum, G. constrictum, G. manihotis).

This study aims to determine the best dose of mycorrhizal biological fertilizer for palm oil seedling growth of DxP Simalungun and DxP Sriwijaya 2 varieties in the pre-nursery stage. This research was carried out by the shade house of the Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir, from October 2020 to January 2021. The study used the Completely Randomized Design method consisting of eight treatments and four replications, in which there were three plants in each experimental unit. The treatment provided consists of A (Simalungun without mycorrhizal), B (Simalungun given 5 g of mycorrhizal), C (Simalungun given 10 g of mycorrhizal), D (Simalungun given 15 g of mycorrhizal), E (Sriwijaya 2 without mycorrhizal), F (Sriwijaya 2 given 5 g of mycorrhizal), G (Sriwijaya 2 given 10 g of mycorrhizal), and H (Sriwijaya 2 was given 15 g of mycorrhizal). The results showed that the treatment of mycorrhizal biofertilizer with a dose of 5 g is the best treatment to the height of seedlings, the number of leaves, the leaf greenness index, the total leaf area, the diameter of the seedlings, the number of roots, the length of roots, and the dry weight of seedlings. The Sriwijaya 2 variety is more responsive to the provision of mycorrhizal biofertilizers.

Production expansion to suboptimal areas such as tidal land through the application of integrated land management technology is an effort to increase soybean production in Indonesia. The study aimed to evaluate the morphophysiological response of soybean treated with arbuscular mycorrhizal fungi (AMF) inoculation and duration of water saturation in tidal land. The study was conducted in April-October 2021 in the plastic house of the Research Field of the Faculty of Agriculture, Sriwijaya University, Palembang. The experiment used a randomized complete block design with two factors and 3 replications. The first factor was the source of AMF propagations (without inoculations, corn inoculants, soybean inoculants, sugarcane inoculants, and soybean-sugarcane inoculants). The second factor was the water saturation periods (0, 2, and 4 months since planting), so there are 15 treatments. The results showed that the interaction between the inoculant sources and the duration of water saturation had no significant effect on all parameters. The inoculant propagated in the media of sugarcane produced the highest effect as compared to other treatments. The water saturation for 2 or 4 months since planting gave soybean plants a better morphophysiological response than conventional cultivation.
