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.
