Cannabis sativa is an annual herbaceous plant, known worldwide for thousands of years. The propose of this study was to evaluate the effect co-inoculation of Trichoderma harzianum and arbuscular mycorrhizal fungi (AMF) on growth of root system and yield in plants of industrial cannabis variety ‘Uso’. A greenhouse experiment took place in the Laboratory of Agronomy at Agricultural University of Athens. The experiment was designed according to Randomized block design with 2 treatments AMF & Trichoderma (AMF&TRCH) application and Trichoderma without AMF application (TRCH) and 3 replications. Trichoderma species have the ability to colonize the rhizosphere of plants, thereby improving the development of the root system. Arbuscular mycorrhizal fungi can form symbiotic relationships with most plants, including species of great economic interest such as industrial hemp. The combined use of Trichoderma harzianum and AMF provoked a synergistic effect increasing the root mass density, bud length and CBD yield per plant. During AMF&TRCH treatment the number of buds, bud dry matter and yield were higher than the TRCH treatment, on the contrary AMF colonization and root volume decreased. In conclusion the supply of AMF&Trichoderma had positive effect on AMF percentage, root and agronomic characteristics.

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

Microbial Strains

Sclerotium rolfsii (Sacc.) is the causal agent of stem-rot in groundnut (Arachis hypogaea L.)crop. With the increase in demand for the groundnut, control of stem-rot efficiently by microbial strains is fast becoming inevitable as the conventional system of chemicals is degrading our ecosystem. This investigation here emphasizes on inoculation of arbuscular mycorrhizal fungi (AMF) and Trichoderma species for growth achievement and disease control. The present investigation showed that these microbial strains were found to be worth applying as they stimulated growth and decreased harmful effects of S. rolfsii (cv. ‘Western-51’). The increased biochemical parameters and antioxidant activities also indicated their defence related activities in groundnut plants. In spite of positive attributes meted out by these microbial strains towards groundnut crop, the interaction among AM fungi and Trichoderma species seemed to be less co-operative between each other which were noted when mycorrhizal dependency and percent root colonization were observed. However, in summary more practical application of low-input AM fungi along with Trichoderma species may be needed for the advancement of modern agricultural systems.

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.

Peppermint (Mentha × piperita L.) is cultivated for its benefits in pharmaceutical, medicinal, and cosmetic industries. The well-known essential oil of Mentha × piperita L. is widely produced and used all over the world. The aim of present study was to evaluate the impacts of different concentrations of chitosan on the quality and quantity of the essential oil from the aerial parts of peppermint under inoculation of the rhizomes of peppermint seedlings with arbuscular mycorrhizal fungi. Experimental treatments were arranged as factorial design in a completed random block design. The highest essential oil yield (2.4 mL 100 g–1 dry matter) was obtained from the peppermint plants under foliar sprayed at 5 g L–1 chitosan along the inoculum with arbuscular mycorrhizal fungi. For evaluation of phytochemical characteristics, the contents of the main constituents of the peppermint essential oils such as menthol, menthone, etc. (oxygenated monoterpenes and monoterpenes hydrocarbons) under different treatments were analyzed by GC-FID and GC/MS. Results indicated that using chitosan foliar meaningfully raised the amount of menthol, as the major constituent and quality index (>60% v/w), in the essential oil from the peppermint plants inoculation with arbuscular mycorrhizal, however, the plants under the foliar spray of chitosan (without inoculum) revealed the highest amounts of menthone and limonene. In conclusion, we found that the foliar-applied chitosan along inoculation with arbuscular mycorrhizal fungi can be improved quantity and quality active substances of Mentha × piperita L. such as the contents of essential oil, menthol, and balance menthol/menthone.

Ultisol is one of marginal soils which requires proper management to increase its fertility. This study aims to determine the administration of Arbuscular Mycorrhizal Fungi (FMA) and cocoa waste compost to FMA colonization, and the growth of cacao seedlings on Ultisols. This research used factorial randomized block design (RBD) with two treatment factors and three replications. The first factor is the type of FMA that is without FMA (F0), Glomus sp (F1), and Glomus sp. + Gigaspora sp. (F2). The second factor is the compost dose which is 0 tons.ha-1 (K0), 20 tons.ha-1 (K1), and 30 tons.ha-1 (K2). The results showed that FMA significantly affected mycorrhizal colonization, but did not significantly affect plant height at 30, 60, 90 HST, stem diameter at 30, 60, 90 HST, and leaf area at 90 HST. Cocoa waste compost has a significant effect on plant height at 90 HST, but no significant effect on plant height at 30 and 60 HST, stem diameter at 30, 60 90 HST, and leaf area at 90 HST. The combination of AMF and compost of cocoa waste significantly affected the stem diameter at 30 HST but did not significantly affect the plant height at 30, 60, 90 HST, stem diameter at 60 and 90 HST, and leaf area at 90 HST. Treatment of FMA type Glomus sp. + Gigaspora sp. and compost 20 g.pot-1 provides the best effect on mycorrhizal colonization and plant growth.
