The research was to obtain information about the combination of fertilizers in the production of arbuscular mycorrhizal inoculums of various depths. This research is using an experimental method. The research uses divided plot design (RPT) with a basic RAK pattern. The treatment factor consists of the main plot (peat depth 0-50 cm and 50-100 cm) and subplot is a combination of fertilizer (P1 = without fertilizing; P2 = NPK+rubberwood vinegar; P3 = NPK+peat vinegar; P4 = NPK+fern-root vinegar). Spore breeding process is ± 3 months. Hosts use sorghum with sterile sand media. The observation variable consisted of the percentage of root infections and the number of spores. Data analysis using ANOVA. Identification of spores based on morphology and Melzer reaction. The results showed that fertilization factors affected the number of spores. The number of spores without fertilization was higher, namely 1642,500 spores compared to combination fertilizers (NPK+fern-root vinegar was 707,667 spores; NPK+rubberwood vinegar was 606,833 spores; NPK+peat vinegar was 206,667 spores). The rate of 0-50 cm colonization without fertilization, NPK+peat vinegar, NPK+rubberwood vinegar is included in the high category. Then in the treatment at 50-100 cm without fertilizing, NPK+peat vinegar, NPK+fern-root vinegar infection rates are also high. The type of spore found is Glomus sp.1; Glomus sp.2; Glomus sp.3; Glomus sp.4. The results of the number of spores and the percentage of root infections showed that organic vinegar was known to not stimulate FMA sporulation, but organic vinegar did not inhibit FMA colonization.Keyword: Mycorrhizal, organic vinegar, peat depth, sorghum

One of the diseases that often found in sorghum plants is anthracnose disease caused by Colletotrichum sp. The purposed of this study was to determine the effect of adding micro fertilizer and the use of several sorghum genotypes on the intensity of anthracnose disease. The study was conducted in Sukanegara, Tanjung Bintang, South Lampung in April 2017 - February 2018 and at the Laboratory of Plant Diseases and Pests, Faculty of Agriculture, University of Lampung. The treatments were arranged using a randomized block design in a split plot design (3 times replications), the main plot was micro nutrients (with micro addition and without micro addition) and 15 subgroups of sorghum genotypes (Numbu, Samurai 1, GH3, UPCA, GH4, P / I WHP, GH6, Super 2, GH13, P / F 51-93-C, Super 1, GH5, Mandau, GH7, and Talaga Bodas). The results showed that the addition of "ZincMicro" micro fertilizers to sorghum plants did not affect the intensity of anthracnose disease, however there were differences in the intensity of anthracnose diseases between sorghum genotypes. Numbu Genotype, GH 3, and GH 13 were relatively more resistant to anthracnose disease than the other genotypes.

Sorghum (Sorghum bicolor (L.) Moench cv. Bok 8) plants were grown in either a high peat or a low organic matter substrate and inoculated with a pigmented strain of Azospirillum brasilense (Cd). Half of the plants were also inoculated with the vesicular–arbuscular mycorrhizal (VAM) fungus Glomus etunicatum, while the remaining plants were fertilized with levels of phosphorus that had been found to be comparable to P input resulting from mycorrhizal colonization. Plants were harvested 1, 3, 5, and 7 weeks postemergence. Total plant dry weight was statistically similar (p > 0.05) between the two treatments for each substrate at all harvests. For each substrate, Azospirillum counts per gram of root were significantly (p < 0.05) higher in mycorrhizal roots at all harvests than in P-fertilized roots, and also higher in the high peat substrate compared with the low organic matter substrate. The ratio of the total number of inoculated A. brasilense cells in the Glomus-colonized compared to the P-fertilized roots was positively and significantly correlated (r = 0.81; p < 0.05) with % VAM colonization. Colonization of sorghum roots by G. etunicatum thus enhanced the establishment and persistence of A. brasilense in the endorhizosphere of sorghum.Key words: Azospirillum brasilense, endomycorrhizae, Glomus etunicatum, rhizosphere, Sorghum bicolor.

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND. This study aims to obtain the right combination of varieties and biofertilizers to increase soybean productivity on Bengkulu coastal land. The research was conducted from March to July 2017, located in Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted with a split-plot design which was repeated three times. The main plot is two soybean varieties (Grobogan and Wilis). The subplots are two types of biological fertilizers, arbuscular mycorrhizal fungi, and phosphate solvent fungi. The results showed that the results of the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) were significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the Wilis variety showed an increase in seed weight (equivalent to 1.12 tons/ha) higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solvent fungi showed superior performance than arbuscular mycorrhizal fungi fertilizer or phosphate solvent fungi. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solvent fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). The economics of resources using arbuscular mycorrhizal fungi are not required to be combined with phosphate solvent fungi.
