       Aren is one type of plant that has the potential to be developed because all parts of the plant can be used. Currently, the cultivation of sugar palm is still traditional and far less than other types of Arecaceae family. The research was conducted from August to October 2016 at the nursery site, and analysis of spore types and AMF colonization in the SEAMEO BIOTROP Bogor Silviculture Laboratory. This research was conducted on palm seedlings that were 19 months old. This study used a completely randomized design with 2 factors, namely P fertilization and AMF inoculation. The P fertilization factor has 2 levels, namely without P fertilization and given P fertilization. The inoculation factor for AMF consisted of 3 levels, namely without AMF inoculation, indigenous AMF, and my cover AMF. The results showed that P fertilization treatment and AMF inoculation did not significantly affect all observed variables, namely plants, number of leaf midribs, length of rachis, plant diameter, SPAD value, number of spores, and root colonization. There was 3 genus of spores, namely Acaulospora sp., Gigaspora sp., and Glomus sp., as well as 2 types of root infections in the form of hyphae and vesicles.

Grafting bibit kopi memiliki tujuan menghasilkan tanaman dengan karakteristik terbaik dari dua varietas kopi yang disambungkan. Kopi robusta digunakan sebagai batang bawah, karena lebih tahan terhadap kondisi yang tidak menguntungkan di lahan gambut. Upaya peningkatan ketahanan batang bawah dapat memanfaatkan mikoriza dan disambungkan dengan kopi liberika sebagai batang atas. Penelitian ini bertujuan untuk  mendapatkan bibit kopi Liberika unggul hasil grafting dengan kopi Robusta bermikoriza serta mendapatkan panjang entres kopi Liberika yang mampu meningkatkan pertumbuhan bibit kopi Liberika hasil sambung pucuk. Percobaan ini menggunakan Rancangan Acak Lengkap faktorial dengan dua faktor dan empat ulangan. Faktor pertama adalah inokulasi mikoriza (tanpa aplikasi mikoriza dan aplikasi mikoriza gabungan Glomus sp-1a dan Glomus sp-3c) dan  faktor kedua berupa panjang entres (10, 15, 20 dan 25 cm). Parameter yang diamati adalah persentase keberhasilan sambungan, waktu pecah tunas, pertambahan tinggi bibit, pertambahan jumlah daun, jumlah tunas, bobot kering tunas, dan infeksi mikoriza. Hasil penelitian menunjukkan respons bibit kopi Liberika hasil grafting dengan bibit kopi Robusta bermikoriza terbaik diperoleh pada panjang entres 15 cm, sedangkan yang disambungkan dengan Robusta tidak bermikoriza diperoleh pada panjang entres 25 cm. Pertumbuhan bibit kopi Liberika hasil grafting dengan bibit kopi Robusta terbaik pada berbagai panjang entres diperoleh pada kopi Robusta bermikoriza.” The main goal of coffee grafting is to create a crop with the best characteristic of two coffee varieties in one plant. Robusta coffee is used as the rootstock, which is more resistant to constraints and unfavorable conditions in the peatland. The effort to increase rootstock resistance is inoculated by mycorrhizae and grafted with Liberica coffee as the scion. This study aimed to obtain the best scion length in order to increase the growth of Liberica coffee with Robusta coffee as the inoculated rootstock. The experiment used factorial completely randomized design with the first factor was mycorrhizae inoculation (without inoculation and inoculation of Glomus sp-1a and Glomus sp-3c combination) and the second factor was  the length of scion (10, 15, 20 and 25 cm). The variables observed were the percentage of success grafted plants, shoot break time, growth (plant height, number of leave, number of shoots, and shoot dry weight) and mycorrhizae infection. The results showed that the plant inoculated by mycorrhizae and scion lenght of 15 cm gave the best percentage of the success graft, shoot break time, and growth of scion.

The Wilt in tomato plants is caused by Fusarium oxysporum sp. Lycopersici. Fusarium oxysporum is soil borne which causes considerable losses. FMA as a biological agent provides an alternative opportunity to control root diseases such as fusarium. The purpose of this study was to study the treatment of FMA inoculation which is appropriate while controlling the damage of tomato plants caused by fusarium. The research design used was the experimental method in Completely Randomized Design. The results showed that the treatment of mycorrhizae inoculated one week before planting and continued with fusarium inoculation at the time of planting showed good results in inducing the resistance of tomato plants to fusarium disease. This is evidenced by root colonization in tomato plants by 53% and the average intensity of attacks by 3.14%. The mycorrhizal treatment inoculated one week before planting and followed by fusarium inoculation at planting also showed good results in increasing the growth of tomato plants compared to other treatments applied by mycorrhiza.

Abstract: The objective of this work was to evaluate the influence of aqueous extracts of nonmycorrhizal weedy species on dry matter accumulation and assimilate partitioning of maize plants, with or without Cetraspora pellucida inoculation. The experiment was carried out in pots, in a completely randomized design, in a 5x2 factorial arrangement consisting of four plant extracts (purple nutsedge, guinea-hen weed, slender amaranth, and knotweed), a control irrigated with water, and two conditions (mycorrhizal and nonmycorrhizal maize plants), with four replicates of each treatment. Plants were irrigated with aqueous extracts diluted at 15%. Root colonization (RC), shoot dry matter (SDM), root dry matter (RDM), and RDM/SDM were evaluated. Root colonization was not influenced by the extracts, and ranged from 41.5 to 65.2%. Shoot dry matter of mycorrhizal (AM) and nonmycorrhizal (NM) plants was not influenced by the extracts; however RDM showed varying responses. Mycorrhization favored the production of RDM, and increased plant sensitiveness to the extracts. Guinea-hen weed extract increased RDM of AM plants, while the other extracts inhibited it. In NM plants, the production of RDM was benefited by slender amaranth extract, to the detriment of SDM. Mycorrhizal and nonmycorrhizal maize plants respond differently to aqueous extracts of nonmycorrhizal weeds.

This study was aimed to examine effect of inoculation with Arbuscular Mycorrhizal Fungi (AMF) and intercropping with several mungbean varieties on yield components of red rice grown under aerobic irrigation technique. The experiment was carried out in a pot in the plastic house from June to September 2017. The experiment was designed using Completely Randomized Design with two treatment factors arranged factorially, i.e. AMF inoculation (M0= without, or M1= with AMF inoculation) and mungbean varieties (V) grown together with red rice plant (V1= Kenari, V2= Vima-1, V3= Vima-3, V4= Merak, and V5= No. 129 ). Each treatment combination was made in triplicate. The results indicated that inoculation had a significant effect in increasing filled panicle number, number of filled grains, and dry grain yield per pot, while decreasing percentage number of unfilled grains. For the rice plants incoluated with AMF, intercropping with mungbean of Kenari and Merak varieties produced similar or higher number of filled panicles compared to those without intercropping. In contrast, for the rice plant without inoculation with AMF, intercropping resulted in lower amount of filled panicles than those without intercropping.

This study aimed to identify a proportion of urea and ammonium sulfate associated to natural reactive phosphate that coud maximize the production of ‘marandu’ grass in a red clayay oxisol with low phosphorus content. The experiment was conducted in a greenhouse with a completely randomized design , in split plots in the time with seven repetitions. The main plots consisted of six levels of the substitution of urea by ammonium sulfate: 0, 20, 40, 60, 80 and 100%. The split plots consisted of three growth periods, being the first 30 days after plants emergence and the others spaced 20 days after the previous evaluation. The evaluated variables were: number of tillers, SPAD value, shoot, leaf blade and stem dry mass. The ammonium sulfate can provide higher soil acidity when compared to urea, which contributes to the reactive phosphate solubilization. Ammonium sulfate increment changes the SPAD value of ‘marandu’ grass fertilized with natural reactive phosphate.
