CLAVIJO PARI, Eduardo José et al. Vegetative development of the sea spine (Hippophae rhamnoides L.), under the application of bovine biol levels in the municipality of Viacha. RIIARn [online]. 2018, vol.5, n.2, pp.43-49. ISSN 2409-1618.

Abstract In the Bolivian highland, one of the main sources of economic income is the raising of livestock whose main source of food is forage, which can be diversified with other varieties or forage species that have adequate development in the highland conditions. It is forthis reason that the vegetative development of the sea spine was evaluated with the application of levels of bovine biol and drip irrigation at the Choquenaira Experimental Station, dependent on the Faculty of Agronomy, Universidad Mayor de San Andrés, located in the municipality of Viacha, province Ingavi of the department of La Paz. The methodology consisted in the application of fourtreatments, T1 (0% biol), T2 (25% biol), T3 (50% biol) and T4 (75% biol), in all cases with addition of water to complete it at 100 %. The variables evaluated were plant height, number of primary and secondary branches, number of leaves, yield in dry matter and bromatological analysis, underadesign of complete blocks at random and Duncan's meanstest in case ofsignificant differences between treatments. We observed a greater number of primary branches, number of secondary branches and number of leaves with T4, this due to the contribution of macronutrients and micronutrients provided by the biol, the results of the bromatological analysis show that T2 has higher protein content, energy value and carbohydrates, this means that the higher the dilution of biol, the greater the absorption of the macronutrients and micronutrients provided by this input. As for the crude fiber, a higher percentage was obtained with the T1 to which biol and water were not added.
