Abstract
El presente trabajo de investigación se realizó en la Estación Experimental Choquenaira, con el objetivo de evaluar el efecto de aplicación del biol bovino en la producción y calidad de cebada en época de invierno. Se contó con un testigo (sólo con la aplicación de agua) que permitió comparar con el tratamiento de 50 % de biol bovino. El riego complementario fue aplicado por aspersión. La siembra del cultivo se realizó el 25 de febrero del 2015 al voleo. Se evaluaron las variables agronómicas, para la altura de planta obteniendo un promedio de 61,42 cm para el tratamiento con biol y 42,90 cm para el testigo. El promedio de macollos fue superior para el tratamiento con biol con 9,5 macollos con solo 7,5 macollos para el testigo. La materia verde de 16,11 t ha-¹ para el tratamiento 50% de biol, mientras que el testigo logró 8,95 t ha-¹ y finalmente el rendimiento promedio de materia seca es significativamente superior en tratamiento con biol con 6,71 t ha-¹, y para el testigo de 3,13 t ha-¹. En las variables bromatológicas para la calidad del forraje para la materia seca el contenido de proteína cruda en el tratamiento con biol de 20,35 g 100g-¹ frente a 15,37g 100g-¹ del testigo. El contenido del valor energético el efecto fue favorable para el tratamiento con biol de 379,99 kcal 100g-¹ y para el testigo de 372,86 kcal 100g-¹, aunque las diferencias no fueron significativas. Para la variable del contenido de fibra cruda se presenta un 374,27 g 100g-¹ para el tratamiento con biol y un 372,41 g 100g-¹ para el testigo
The present research was conducted at the Experimental Station Choquenaira, with the objective of evaluating the effect of application of bovine biol in the production and quality of barley in winter. There was a control (which consists only with the implementation of water) that allowed the comparison with the treatment of 50 % of bovine biol veal. The supplementary irrigation applied is the method of sprinkler irrigation. The crop was sown on 25 February 2015, with a scatler sowing . The evaluated variables included the plant height getting an average of 61,42 cm for the treatment with biol and 42,90 cm for the control. The average tillers was higher for the treatment with biol with 9,5 tillers and 7,5 tillers for the control. The green matter obtained was 16,11 t ha-¹ for the treatment 50 % biol, while the control produced only 8,95 t ha-¹ finally there is the average yield of Dry matter significantly higher in treatment with biol with 6,71 t ha-¹, and only 3,13 t ha-¹. for the control. In the qualitative characteristics in relation to the quality of the forage in dry matter content of crude protein presents for the treatment with biol of 20,35 g 100g-¹ versus 15,37 g 100g-¹ for the control. The energy content has shown the favorable effect forthe treatment with biol of 379,99 kcal 100g-¹ and forthe control of 372,86 kcal 100g-1, although the differences were not significaní. Forthe variable of the crude fiber content presents a 374,27 g 100g-¹ forthe treatment and a 372,41 g 100g-¹ forthe control.
