Comparación entre dos fertilizantes en la producción de pastos dallis (Brachiaria decumbens) en la comunidad Nuevo Ecuador, cantón Joya de Los Sachas.

Abstract

The outcome of this study was to compare the effectiveness between urea and biol application in different development ages to improve the quality of Dallis grass production (Brachiaria decumbens). For which it was carried out using Completely Random Block Design with four treatments: (Tl) urea, (T2) biol, (T3) urea plus biol, and (T4) witness, after fertilization alternatives, the differences in botanical data collection and its chemical composition, the size per experimental unit was 127.35 m2, with 3 repetitions per treatment, using 12 experimental plots. For statistical analysis, a General Linear Model was applied, the data were compared with Dunnett test, resulting in a significant difference in agronomic performance between the treatments applied with 100% nitrogen fertilization and in a combination of 50% urea and 50% biol, in the same way as in the chemical composition which presented a protein content (8.0%/kg), crude fiber (33%/kg), neutral detergent fiber (72%/kg), acid detergent fiber (41%/kg), dry matter (27%/kg) when using urea plus biol, the treatment that reflected the best production cost/kg of dry matter was use 50% urea + 50% biol and 100% biol. According to the results obtained, it is concluded that 100% urea and urea+biol treatment showed higher productive yields. It is recommended to combine biol with a nitrogenous source since it can be considered an alternative in sustainable production to improve dallis grass quality.
