Arbuscular mycorrhizal fungi (AMF) are naturally found in the soil. The population of this fungus is influenced by environmental factors such as soil type. Different soil types have different characteristics and will affect the AMF population in the soil. Therefore, this study was carried out to determine the AMF population in the soil based on the number of spores in the rhizosphere of oil palm planted in 4 different soil types, namely Dystrudepts, Paleudults, Haplohumods, and Haplosaprists. Soil samples were taken from each soil type at 4 sample points. At each sample point, soil samples were taken from 5 adjacent oil palm trees. Rhizosphere soil samples were taken at 4 points inside the oil palm circle at a depth of up to 15 cm and 4 points from the outside and then composited to represent 1 sample point for inside and outside the circle. Extraction of AMF spores from soil samples was carried out by the wet sieving method. The results showed that the average number of AMF spores per 50 g of rhizosphere soil from inside and outside the oil palm circle were 66,7 and 53,5 spores for Dystrudepts, 115,5 and 91,5 spores for Paleudults, 27 and 71,8 spores for Haplohumods, and 83,3 and 55 spores for Haplosaprists respectively. In Dystrudepts, Paleudults, and Haplosaprists soil types, the number of spores in the rhizosphere of oil palm inside the circle was higher than outside. On the other hand, for Haplohumods soil types, the number of spores inside the circle was lower than outside the circle.

“…Until this observation was carried out, namely oil palm aged TBM-3, no symptoms of stem rot disease were found. Study reported by [24] found a positive correlation between AMF biodiversity and soil pH. Although this correlation may be influenced by the history of land use (fertilizer and herbicide application) in oil palm plantations, differences in soil characteristics can determine differences in AMF communities.…”

“…Naturally, in the oil palm rhizosphere, AMF isolates consist of Glomus and Gigaspora; the number of AMF spores in the oil palm rhizosphere is different for each variety, type, age of oil palm plants, and also season. While sampling also affected the number of AMF spores, the density of spores isolated from oil palm soil samples ranged from 7 -127 spores/ 200 g of soil [35]; 306 spores/50 g soil [33]; 61 -65 spores/ 50 g soil at the age of 5 -15 years of oil palm plantations [36]; spores density varied from low: 0.81/50 g soil to moderately: 1.33 -1.51/50 g soil [24].

Biological agents are critical in the management of major diseases in oil palm plantations. The potential of arbuscular mycorrhiza fungi (AMF) and Trichoderma spp. to control basal stem rot disease was investigated in this study. Three-month-old seedlings treated with AMF since the beginning of planting demonstrated AMF colonization of the roots. With a 25 gram AMF treatment in the main nursery, AMF colonization increased by 85.99% in TBM-1 (the 1-year immature plant). In TBM-2, AMF colonization increased by 86.00-97.33% (2-year immature plant). All of the treatments started with 30 grams of Trichoderma spp. applied at the start of pre-nursery planting. Root colonization and the number of spores in the root rhizosphere in TBM-2 had a strong relationship (2-year immature plant). AMF inoculation had a significant impact on root colonization and spore number response. According to this study, the application of 25 grams of AMF in the pre-nursery and main nursery, as well as repeated additions at planting, were found to be effective in controlling attacks of basal stem rot disease through early prevention strategies.

Ganoderma boninense is the main pathogen in oil palm plantation areas and can infect new plants, thereby shortening the economic life of each crop cycle. Until now, no adequate control has been found to minimize the incidence of basal stem root (BSR) disease. Preventive control strategy through replanting and applying Arbuscular Mycorrhizal Fungi (AMF) and Trichoderma sp. since nursery can be an approach in managing BSR disease. This study aims to determine the effect of biocontrol agents' application of AMF and Trichoderma sp. at the nursery on the incidence of BSR in the field. The treatments assessed were types (MM, MR, and MT) and dosages (25, 50 and 75 g per seedlings) of AMF products and each treatment was replicated three times. Arbuscular Mycorrhizal Fungi was applied in the main nursery and at planting in the field. Observations were made on AMF and Trichoderma sp. spore density and AMF colonization at plants aged 4, 5, 6, and 7 years while the incidence of BSR was observed for ten years, from one year before replanting up to TM-5. The experimental design carried out was a randomized block design. The results showed that the MM-25 treatment was the best treatment in terms of AMF colonization percentage of 98 % and total AMF spores of 688 spores per 100 g soil at plants aged seven years. However, the population of Trichoderma sp. showed inconsistent numbers during the observation. Before replanting, the oil palm plantation area showed a BSR incidence of 21.37%. However, after replanting with the application of AMF and Trichoderma sp. on seedlings, the incidence of BSR became 0 until plants aged eight years (TM-5). In general, the application of AMF reduces the BSR incidence of oil palm in the field.[Keywords: biocontrol agents, basal stem rot, AMF, oil palm, replanting] AbstrakGanoderma boninense merupakan patogen utama di areal perkebunan kelapa sawit dan dapat menginfeksi tanaman baru, sehingga memperpendek umur ekonomis setiap siklus tanaman. Sampai saat ini belum ditemukan pengendalian yang efektif untuk meminimalkan kejadian penyakit busuk pangkal batang (BPB). Strategi pengendalian preventif melalui peremajaan dan aplikasi Fungi Mikoriza Arbuskular (FMA) dan Trichoderma sp. sejak pembibitan dapat menjadi salah satu pendekatan dalam pengelolaan penyakit BPB. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi agens biokontrol FMA dan Trichoderma sp. di pembibitan terhadap kejadian BPB di lapangan. Perlakuan yang diuji adalah jenis (MM, MR, dan MT) dan dosis (25, 50 dan 75 g per bibit) produk FMA dan masing-masing perlakuan diulang tiga kali. Fungi Mikoriza Arbuskular diaplikasikan di pembibitan utama dan saat tanam di lapangan. Pengamatan dilakukan terhadap kepadatan spora FMA dan Trichoderma sp. serta kolonisasi FMA pada umur tanaman 4, 5, 6, dan 7 tahun sedangkan kejadian BPB diamati selama sepuluh tahun dari satu tahun sebelum peremajaan hingga TM-5. Rancangan percobaan yang digunakan adalah rancangan acak kelompok. Hasil penelitian menunjukkan bahwa perlakuan MM-25 merupakan perlakuan terbaik ditinjau dari persentase kolonisasi FMA sebesar 98% dan total spora FMA sebesar 688 spora per 100 g tanah pada tanaman umur tujuh tahun. Namun populasi Trichoderma sp. menunjukkan angka yang tidak konsisten selama pengamatan. Sebelum peremajaan, areal kelapa sawit menunjukkan kejadian BPB sebesar 21,37%. Namun setelah dilakukan peremajaan dengan aplikasi FMA dan Trichoderma sp. pada bibit, kejadian BPB menjadi 0 sampai usia tanaman delapan tahun (TM-5). Secara umum, aplikasi FMA mengurangi kejadian BPB kelapa sawit di lapangan.[Kata kunci: agens biokontrol, busuk pangkal batang, FMA, kelapa sawit, peremajaan]
