Utilización de dos tipos de bioles en la producción forrajera de Brachiaria brizantha en la Finca Porvenir del cantón El Triunfo

Abstract

At Porvenir`s soil assessed the use of bioles (Bovine and chicken manure) and dose (20 and 40 cc/lt) in forage production of Brachiaria brizantha. They were compared with a control (without fertilization) by using 20 plots of 20 m2 plots under a DBCA – Bifactorial of 2x2. The experimental results were subjected to ANOVA for differences and averages separations by Tukey P ≤ 0.05. The first evaluation presented statistically significant differences in plant height at 30 and 45 days (61.96 and 85.05 cm) using biological bovine with 40 cc/lt respectively. The obtained basal and aerial coverage were obtained with the bovine boil (84.99 and 86.23%) with the dose of 40 cc/lt (87.16 and 87.46%) orderly. The number of leaves/stem (5.67 and 5.98) was obtained with bovine boil 40 cc/lt and the relationship of stems/plant (7.09) with bovine biological 40 cc/lt. On the other hand the green fodder production (114.57 and 122.68 tons/ha/year) was obtained with bovine biological and dose 40 cc/lt respectively. The production of MS (29Tn/ha/year) obtained with biological bovine with 40 cc/lt. The second assessment showed a similar behaviour to the first, finding significant differences in plant height at 15 days (17, 98 and 18,54cm) by using bovine biological dose 40 cc/lt sequentially. The highest % of forage protein quality (11.34%) was obtained with biological manure 40 cc/lt and the lowest fiber content was (32, 06%) with bovine biological 20 cc/lt, so that they did not improve the soil quality by analysis. It recommends the use of biological bovine at 40 cc/lt because of its benefit – cost of ($1.51).
