Evaluación de diferentes abonos foliares de biol (Cuy, bovino y pollinaza) en la producción forrajera de Setaria sphacelata (Pasto miel), en el cantón San Miguel de los Bancos

Abstract

At the facilities of la Merced farm, of the San Miguel de los Bancos canton, different biological foliar fertilizers was evaluated in forage production of Setaria sphacelata, the experimental results were tabulated under a design randomized complete block, resulting in the use of poultry manure biol, reported greater plant height at 15 (69.21 cm) and 30 days (102.57 cm), number of stems per plant at 15 days (5.97), greater number of leaves per stem at 30 days (5.82), aerial coverage at 30 days (100%), production of green forage and, dry matter (37696 kg/ha/cut) and (5160 kg/ha/cut), respectively, and the most efficient value of preflowering (33 days). In the second fertilization results remain favorable to fertilize with poultry manure (T3), especially in the green forage yield (37368 kg/ha/cut) and dry matter (5200 kg/ha/cut), and less time the pre-flowering (35 days). When done physical chemical analysis was determined as the best type of poultry manure biol for the most nutritional value. Bromatological assessment of Setaria sphacelata in the first and second cut, reported using the highest biological values of poultry manure. Soil analysis before and after fertilization indicate a substantial change in the content of nutrients as there was an increase of nitrogen, organic matter, pH and humidity. Economically the best treatment was the application of poultry manure biol because it records a cost of 1.93 profit.
