Description
Summary:The objective of obtaining forage oats varieties of livestock feed, the EEA Andenes -INIA, in 2019 the new INIA 908 -Mellicera variety was obtained. Since 2013 to 2016 agricultural seasons were evaluated with the line L8 and the control variety INIA 903 -Tayko Andenes in check plots. The experimental design was completely randomized blocks with three repetitions in each region. Protein content increases to 50% flowering (21.44%), and decreases (17.61%) 100% flowering, increasing the fibre content by 3.26%, decreasing fodder quality. The optimal use of forage with L9 treatment from 1 to 50% visible inflorescence. The new variety showed higher values than the local oats (Tayko), used by livestock producers. The M.S yield can be observed in nine regions of 11.39 t ha-1, and the content is higher than local variety, which on average yielded 7.19 t ha-1and on average superior seed yield 3.58 t ha-1was obtained. Mellicera oats are extraordinarily resilient to climate change and allowing the producers to harvest seed in the high Andean regions due to its precocity (153 days), compared to Tayko. Con el objetivo de obtener variedades de avena forrajera para alimentación de ganado, la EEA Andenes del INIA en el año 2019 obtiene la nueva variedad denominada INIA 908 - Mellicera. En las campañas agrícolas de 2013 a 2016 se evaluó con la línea L8 y variedad testigo INIA 903 - Tayko Andenes en parcelas de comprobación. El diseño experimental utilizado fue bloques completamente randomizado con tres repeticiones en cada localidad. El contenido de proteína incrementa al 50% de floración (21,44%), y disminuye (17,61%) al 100% de floración, incrementando el contenido de fibra en 3,26 % y disminuyendo la calidad del forraje. El uso óptimo de forraje con el tratamiento L9, es del 1 a 50% de inflorescencia visible. La nueva variedad demostró valores superiores a la avena local (Tayko), se puede observar un rendimiento promedio de M.S. en las 9 localidades de 11,39 t ha-1, nivel superior a la variedad local, que en promedio rindió ...
