Humus líquido más abono bovino en la producción primaria forrajera de la Brachiaria decumbes (Pasto dallis).

Abstract

This present investigation was carried out in the province of Pichincha, Los Bancos Canto, precinct “San Bernabe”. The agronomic behavior of brachiaria decumbes (Dallis grass) was evaluated, with liquid humus application: 200,400, 600 and 800 liters plus bovine manure: 20 Tn/ha and different application times: 5, 10 and 15 days. Thirty six experimental units were used, with an area of 20 m2 each, giving a total area of 720 m2. The distribution of the treatments was done through a complete block design at random (DBCA). The best performances of green forage were collected in the first cutting with the use of 200 l/ Ha liquid humus + 20 tons/ ha bovine manure at 10 days with a production of 5, 90 tons/ Ha cutting. The responses with the best performance regarding to height of the plant, were evidence with the application of treatment A1B1 (200 l /ha liquid humus + 20 tons/ Ha bovine manure at 15 days) with a height of 63,40cm. The highest percentage of basal covering (56, 22%) and aerial (79,56%) of Dallis grass, was recorded in the second cutting to fertilize the soil with 400 l / ha liquid humus + 20 tons / Ha bovine manure at 15 days. Using this type of fertilizer a benefit/cost ratio of 1, 21 was obtained. Therefore, it is recommended to promote Dallis grass fertilization with 200 l / Ha liquid humus + 20 tons / Ha bovine manure at 10 days, because forage production is improvement in both green and dry matter.
