Evaluation of Brachiaria Decumbens Production by Humus Plus Mycograss Biofertilisers Effect

Objective: This research was carried out in Pichincha Province, San Miguel de los Bancos Canton, San Bernabe Sector, in which the agronomic performance of Brachiaria decumbens was evaluated, by applying different levels of humus: 2, 4, 6, and 8 ton/ha plus 4 kg/ha of mycorrhizae, compared to a control treatment (T0). Theoretical Framework: Producers around the world have taken up organic agriculture with intensive crops, not only in products for human consumption but also in the production of pasture and fodder for animal feed, because it has been proven that the use of biofertilisers such as humus and mycorrhizae improve the physical and nutritional conditions Method: 20 experimental units were used with an area of 25 m2, each with 4 replicates giving a total area of 500 m2. The distribution of treatments was performed through a complete randomized block design with four replications (RCBD). Results and Discussion:When the results were evaluated, the best production was achieved, when using 8 ton/ha of humus more than 4 kg/ha of mycorrhizae in pastures, showing in the first and second cutting the plant height in 30 days (53.40 and 65.85 cm), coverage area during 30 days (91.44 and 91.06 %), production of biomass grass (3.16 and 9.95 ton/ha), and dry matter production (0.55 to 1.75 ton/ha) respectively. When using 0 ton/ha of humus with 4 kg/ha of mycorrhizae in the second replicate, a benefit/cost of 1.24 was obtained; with a profitability of 24%. Thus It is recommended to use 8 ton/ha of humus with 4 kg/ha of mycorrhizae because their profitability was better in the production. Research Implications: In the fight against climate change, the use of synthetic fertilisers has been the subject of objections from the scientific community. For this reason, a new front of work is opening up in the search for strategies to mitigate the adverse effects of chemical fertilisers with a high carbon footprint. Originality/Value: The relevance and value of this research are very important at level to Ecuador as an alternative to replace the use of synthetic fertilizer in pastures.
