Intensive soil tillage in sugarcane plantation may cause soil degradation including soil microorganism activities. The experiment was conducted at PT GMP to test the effect of soil tillage systems and bagasse application on arbuscular mycorrhiza fungi (AMF) population. The experimental design used was a completely randomized design arranged in a split plot with five replications. The main plot consisted of intensive soil tillage and no tillage system. The sub-plot consisted of 80 ton ha-1 bagasse application, and without bagasse application. The result showed that AMF population in intensive soil tillage was not signicantly different over no tillage system. AMF population in the soil applied with 80 t ha-1 bagasse was also not signicantly different over no bagasse. There was no interaction between soil tillage systems and bagasse application on arbuscular mycorrhiza fungi (AMF) population. Key words: arbuscular mycorrhiza, population, sugarcane, soil tillage, bagasse

Host plant and medium are factors that affecting Abusrcular Mycorrhiza Fungi (AMF) production. Therefore, for maximum FMA inoculums production, four different host (mays, sorghum, Centrosema pubescens [CP], and Calopogonium mucunoides [CM]) and two medium (zeolit P-1 and zeolit P-3) were tested. The results showed that host from graminae (mays and sorghum) are better for AMF inoculums production as they gived higher root infection and spore production compared to legume (CP and CM). No significant effect was detected between P-1 and P-3, hence both medium can be used for AMF production. Furthermore, data obtained also showed that the effect of host on AMF production was not affected by medium used. Key words: Arbuscular Mycorrhiza Fungi, inoculums production, host, medium

Fungi mikoriza arbuskular (FMA) hidup di akar tanaman dan memberikan banyak manfaat untuk tanaman inangnya. Salah satu faktor yang mempengaruhi produksi spora FMA adalah pertumbuhan tanaman inang. Oleh karena itu, penelitian ini bertujuan untuk mencari jumlah tanaman inang yang sesuai untuk memproduksi FMA. Peneltian menggunakan rancangan perlakuan tunggal tidak terstruktur, yaitu jumlah tanaman inang yang terdiri dari 1 tanaman/pot (t1), 2 tananam/pot (t2), 3 tananaman/pot (t3), 4 tanaman/pot (t4), dan 5 tanaman/pot (t5). Setiap perlakuan diulang sebanyak 4 kali. Rancangan percobaan mengguanakan rancangan acak kelompok. Kecambah tanaman jagung berumur 3 hari diinokulasi dengan 2 spora Glomus sp. isolat P-186-2. Kecambah kemudian ditanam di tengah-tengah pot berukuran 1100 ml yang telah diisi dengan campuran pasir sungai steril dan zeolite (1:1 =V:V). Kecambah jagung ditambahkan jika jumlah tanaman inang lebih dari satu. Tanaman dipelihara di rumah kaca selama 3 bulan setelah inokulasi. Hasil penelitian menunjukkan bahwa semua perlakuan menghasilkan persen infeksi akar yang tidak bebeda dengan nilai infeksi >70%. Namun, jumlah tanaman inang jagung 5 tanaman pot menghasilkan jumlah spora tertinggi dibandingkan dengan perlakuan lainnya.

Produksi fungi mikoriza arbuskular sangat dipengaruhi oleh media tanam dan tanaman inang. Oleh karena itu penelitian ini bertujuan untuk mendapatkan volume media tanam dan jumlah tanaman inang yang terbaik untuk memproduksi spora fungi mikoriza arbuskular (FMA). Penelitian menggunakan rancangan faktorial 5x 5 dengan faktor pertama volume media tanam yang terdiri dari 200 ml, 400 ml, 600 ml, 800 ml, dan 1000 ml. Sedangkan faktor ke dua adalah jumlah tanaman inang per pot yang terdiri dari 1, 2, 3, 4, dan 5 tanaman. Setiap perlakuan diulang sebanyak 4 kali. Media tanam yang digunakan adalah campuran pasir sungai steril dengan zeolite dengan perbandingan 1: 1 berdasarkan volume dan tanaman inang yang digunakan adalah Pueraria javanica. Tanaman inang dipelihara di rumah kaca hingga 4 bulan kemudian dikeringkan (tanpa disiram selama 2 minggu) untuk memicu produksi spora. Data hasil penelitian menunjukkan bahwa volume media tanam yang paling sesuai untuk memproduksi spora FMA adalah 400 ml dengan jumlah tanaman inang sebanyak 5 tanaman. Dari perlakuan ini diperoleh jumlah spora terbanyak dibandingkan perlakuan lainnya.

Arbuscular mycorrhizal fungi (AMF) is a type of fungus that comes from the endomycorrhizal group, these fungi have the ability to form symbiosis with almost 90% of higher plant species. Population and diversity of AMF are influenced by biotic factors and abiotic factors. This research aims to determine the differences in population, diversity and dominant types of AMF in the rhizosphere of pepper planted in monoculture and pepper in polyculture. The soil samples were taking from monoculture and polyculture pepper plantations in Air Naningan District, Tanggamus Regency. The AMF population was tested using the One way Annova test. Culture trapping was done using a factorial treatment with the first factor being the origin of the soil sample (K) and the second actor being the type of host plant (T). Treatments design used was randomize design (CRD). The results showed that the AMF population in polyculture pepper plantation soil samples was higher than monoculture pepper, based on the Shannon-Wiener Diversity Index, AMF diversity in monoculture pepper and coffee intercropping pepper plantations was higher than in cocoa intercropping pepper plantations, and the type of AMF was dominant. from the results of trapping culture with monoculture pepper garden soil samples, namely spores of the species code S7, in samples of coffee intercropping pepper plantations the code S7 is dominant, while in cocoa intercropping pepper plantations it is dominated by code S6. Keywords: Arbuscular mycorrhizal fungi, diversity, population.

Pineapple (Ananas comosus [L.] Merr.) is one type of fruit that has an important role in Indonesia because it is a major export commodity, both in fresh and processed forms such as canned fruit and juice. Therefore, the development of pineapple production is a strategic matter. One of the steps taken to increase pineapple production is through proper and balanced fertilization. The objective of this study was to determine the best fertilizer package that supports the growth of pineapple plants. The research was conducted from November 2022 to March 2023 using a single-factor Randomized Group Design (RAK), consisting of treatments and repeated 4 times. The treatment packages tested included the dose and interval of fertilization, namely: P0= 200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30 HST), P1= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), P2= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4+ 50 kg ZA per ha (0, 15, 45 HST), P3= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), and P4= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 100 kg ZA per ha (0, 15, 45 HST). In each experimental unit, 5 sample plants were selected, so that the total plants observed were 100 sample plants. The data were analyzed using analysis of variance, and the F test showed significant differences which were then further tested with the Least Significant Difference (BNT) test at the 5% level. The results showed that in general, fertilizer doses and intervals had no significant effect on most of the observed variables, except on d-leaf width and d-leaf length. The fertilizer package in the P0 treatment (200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA) per ha proved to be the best to support pineapple plant growth. Keywords: dosage, fertilization frequency, pineapple, inorganic fertilizer
