Evaluation of inoculum arbuscular mycorrhizal fungi in Brachiaria decumbens

Abstract

Arbuscular Mycorrhizal Fungi (AMF) can help plants to uptake nutrients, especially phosphorus, so that plants will produce sustainably. The study aimed to evaluate the inoculum of AMF obtained by hydroponic techniques, such as spray, drip, and NFT (Nutrient Film Techniques), with different nutrients Hyponex red and AB mix on Brachiaria decumbens grass. The experimental design used randomized complete design with 7 treatments namely control, SP1 (Spray/Hyponex red), SP2 (Spray/AB mix), NP1 (NFT/Hyponex red), NP2 (NFT/AB mix), DP1 (Drip/Hyponex Red), DP2 (Drip/AB mix). Variables measured were production of shoot dry matter; content, and uptake of phosphorus, nitrogen, and crude protein. The results showed that AMF inoculum significantly (p<0.05) increased shoot dry matter production, phosphor, nitrogen, and protein content when compared with control. Phosphorus uptake in SP2 gave the best results but not significantly different from NP1, NP2, and DP1, but significantly different (p<0.05) with SP1, DP2, and control. The AMF inoculum significantly (p<0.5) increased nitrogen and protein uptake when compared to control. The conclusion that AMF inoculum increased shoot dry matter, phosphor, nitrogen, and protein content, and uptake of phosphorus, nitrogen, and protein. The inoculum that has been produced can be used by the community to increase productivity.

Tissue Analysis of Sweet Corn (Zea mays L. var. saccharata) Applied with Mycorrhizal Inoculants and Varied Fertilizer Rates

“…The AMF inoculum dramatically boosted nitrogen and protein intake in Brachiariadecumbens, according to results from Karti et al, 2021. Hestrin et al, 2019 shows that arbuscularmycorrhizal fungi are common symbionts of terrestrial plants that can enhance plant nitrogen uptake but have restricted access to organic nitrogen.…”

Arbuscular Mycorrhizae for Sustainable Cultivation of Grasses

“…In the first studies, U. decumbens was inoculated with G. margarita and Glomus. clarum to study the recovering of degraded lands in greenhouse experiments, as showed by Santos et al [42]. For mycorrhizal treatments, there are various possible procedures: 1) small holes can be prepared in the soil/ substrate surface of each pot, and the inoculum (~ 2.5 mL) placed in each hole: 2) Other procedure is to throw the spores into the roots of each plant( before transplanted) or pot.…”

Development of Nutrient Film Techniques on Solar-Powered Internet of Things Devices for Aeroponic Planting

“…Automated work processes are beneficial for farmers because they can reduce the need for human resources for their management [7]. This technique of spraying nutrients on the roots is called nutrient film technique (NFT) [8]. This technique is commonly used in hydroponic growing methods where nutrients are mixed into water and flowed in a channel where, above, plants are placed whose roots touch the water full of nutrients [9].…”
