Abstract
En la actualidad la producción FVH es una alternativa para obtener forraje verde en menor tiempo y en época de déficit. El objetivo del estudio fue mejorar la producción del FVH utilizando tres densidades de siembra en relación a dos métodos de producción en el cultivo de cebada. El estudio fue realizado en la Estación Experimental Cota Cota dependiente de la Facultad de Agronomía de la Universidad Mayor de San Andrés, se emplearon los métodos pre-germinativos de Tarrillo y FAO bajo tres densidades de siembra, resultando en seis tratamientos que fueron dispuestos bajo un diseño de bloques completamente al azar con arreglo bifactorial, asimismo se realizó la prueba de Duncan para los resultados de las variables altura de planta, largo de la raíz, rendimiento de biomasa y porcentaje de materia seca. Los resultados muestran que existen diferencias estadísticas en altura de planta, diferencias entre los métodos empleados, con mejor respuesta por el método de Tarrillo con un promedio de 8.33 cm y una densidad de 2.5 kg m-² de acuerdo a la prueba de Duncan, en cuanto al largo de la raíz existen diferencias, con la densidad de siembra de 2.5 kg m-² el largo de la raíz fue de 13.51 cm, con la misma densidad de siembra con el método de Tarrillo, el rendimiento de biomasa fue 7.8 kg 0.5m-². El porcentaje de materia seca fue 64.96% indicando que no influye la densidad ni el tipo de método pre-germinativo sobre esta variable. El forraje verde hidropónico obtenido en la investigación tuvo entre 10% y 11% de proteína cruda. Estos resultados muestran que el método de Tarrillo combinado con la densidad de siembra de 2.5 kg m-²da mejores resultados para la obtención de FVH que puede ser utilizado para la alimentación del ganado.
Currently, FVH production is an alternative to obtain green fodder in less time and in deficit period. The objective of the study was to improve the production of the FVH using three planting densities in relation to two production methods in the barley crop. The study was carried out at the Cota Cota Experimental Station under the Faculty of Agronomy of the Major San Andrés University. The pre-germination methods of Tarrillo and FAO were used under three planting densities, resulting in six treatments that were arranged under a completely randomized blocks design with bifactorial arrangement, also the Duncan test was performed forthe results of the variables plant height, root length, biomass yield and percentage of dry matter. The results show that there are statistical differences in height of plant, differences between the methods used, with better response by the method of Tarrillo with an average of 8.33 cm and a density of 2.5 kg m-² according to the Duncan test, in As forthe length of the root there are differences, with the densityofsowing of2.5 kg m-²the length of the root was 13.51 cm, with the same density ofsowing with the method of Tarrillo, the yield of biomass was 7.8 kg 0.5 m-² The percentage of dry matter was 64.96%, indicating that neither the density nor the type of pre-germinative method influences this variable. The green hydroponic forage obtained in the research had between 10% and 11% of crude protein. These results show that the Tarrillo method combined with the sowing density of 2.5 kg m-² shows better results for obtaining FVH that can be used for livestock feed.
