TAMBO LAIME, Dora; CESPEDES PAREDES, Rolando  e  ESPRELLA VIOREL, Blesmi. Evaluation of the effect of bovine biol in production and quality of barley (Hordeum vulgare L.), in winter period of the Experimental Station Choquenaira, Viacha - La Paz. RIIARn [online]. 2016, vol.3, n.1, pp.55-66. ISSN 2409-1618.

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.
