Agronomic Responses of Medicago Sativa by Effect of Different Manure Tea

Objective: a study was conducted about the use of different manure tea, bovine (T1), sheep (T2), poultry manure (T3) and the control (T0). Theoretical Framework: The use of synthetic fertilisers with a high carbon footprint, due to their environmental implications, is currently a matter of great concern in the international scientific community. For this reason, the use of environmentally friendly alternative resources is a subject of great interest, and has been the reason for researching alternatives for their application in practice. Method: They were applied at 15 days post cut of the preset alfalfa crop, the investigation lasted 184 days the size of the experimental units were 4x5 meters with five replicates per treatment damaged a total of 20 experimental plots with a total net area of 400 square meters test. The distribution of treatment was performed using a nested design complete randomized block experiment. Results and Discussion: The results report that the best results were obtained by applying the treatment of poultry manure tea in the three replicas of the production test with an average of three cuts of green fodder, dry matter, plant height, stems/plant, leaf/stem, coverage area, basal coverage, and cost of 12.05 tons/ha/cut of green fodder, 2.17 tons/ha/cut of dry matter, 79.91 cm plant height, stem 53.04/plant, leaves 41.40/stem, 94.26% coverage area, 61.74% of basal coverage and 141% return. So, we recommend using poultry manure to cut 15 days post because the best production rates were reported. Research Implications: At the local level, these results are very interesting due to the fragility of biodiversity and anthropogenic changes that have caused severe pressure on biotic components. Originality/Value: The lack of information on fertilisation alternatives makes this work unprecedented and contributes to the generation of information for the livestock sector in Ecuador and the region.
