La “quínoa” (Chenopodium quinoa) como alternativa forrajera en la zona de los Valles Calchaquíes (Noroeste Argentino)
González, Juan A., Guillermo O. Martín (h), Marcela A. Bruno, Fernando E. Prado. 2016. “Quínoa ( Chenopodium quinoa) crop as fodder supplement in Valles Calchaquíes (Argentinean Northwest)”. Lilloa 53 (1). Quínoa is multipurpose specie that may be utilized as grain for human nutrition or fodder production destined to animal (cows, goats, sheep, lla- mas, among others) in some places where natural pastures are scarce. Traditionally quinoa is sown by hand and a high plant density was obtained. In order to avoid plants competition it is necessary to clear eliminating a lot of plants. The objective of this study is the evaluation of the eliminated plants for fodder. This paper contributes with data of aerial dry matter (leaves and stems) in 9 quínoa varieties and 1 genotype (landrace) cultivated in Amaicha del Valle (1,995 m asl, Tucumán, Argentina) of 110 days old. Shoot dry matter production oscillated between 7.7 Tn/ha (var. Sajama) to 2.7 Tn/ha (var. Samaranti). Leaf chemical analysis showed and elevated concentration of potassium (K) in all varieties with an oscillation of 8.54 % (Kancolla) to 9.93 % (Samaranti). Other minerals exhibited a low concentration and in general were 3.9 – 5.4 % for N; 0.20-0.34 for P; 2.5 -3.04 for Ca and 0.87-1.57 for Mg. Organic matter content showed a variation between of 37.7 % (var. Sajama) and 42 % (var. Kancolla). Leaves and stem protein mean content were 15.7 % and 9.9 % respectively. Total fibers content was higher in stem in relation to leaves but the ash content was the opposite. To take into account dry matter production and protein, fibers and minerals content quínoa may be a good complement fodders for animals that take part in livestock production in Valles Calchaquíes.

González, Juan A., Guillermo O. Martín (h), Marcela A. Bruno, Fernando E. Prado. 2016. “El cultivo de ‘quínoa’ ( Chenopodium quinoa) como complemento forrajero en la zona de los Valles Calchaquíes (Noroeste Argentino)”. Lilloa 53 (1). “ Quínoa ” es una espe- cie multipropósito que puede ser utilizada como granos para alimentación humana o bien para la producción de forrajes, destinados a complementar la alimentación de animales (vacas, cabras, ovejas, llamas, entre otros) en zonas donde las pasturas naturales son escasas. Tradicionalmente la siembra se realiza a chorrillo con lo que se obtiene una alta densidad de plantas en el surco, que posteriormente es necesario ralear para evitar la competencia entre ellas. El raleo lleva implícita la eliminación de las plántulas. El objetivo de este estudio es jus- tamente la evaluación de las plantas eliminadas para ser utilizadas como forraje. Este trabajo aporta datos de producción de materia seca aérea (hojas y tallos) en 9 variedades de quínoa cultivadas en Amaicha del Valle (1.995 m snm, Tucumán, Argentina) y un genotipo (landrace) a los 110 días de siembra. El análisis de la producción de materia seca aérea varió entre 7,7 /ha (var. Sajama) y 2,7 /ha (var. Samaranti). El análisis químico foliar mostró un con- tenido elevado de K en todas las variedades con porcentajes que oscilaron entre 8,54 % (Kancolla) y 9,93 % (Samaranti). Los restantes minerales exhibieron valores menores, que en general, oscilaron entre 3,9-5,4 % para N ; 0,20-0,34 % para P; 2,50-3,04 % para Ca y 0,87-1,57 % para Mg, entre otros. El contenido de materia orgánica osciló entre 37,7 (var. Sajama) y 42 % (var. Kancolla). El contenido promedio de proteína foliar y de tallos fue del 15,7 y 9,9 % respectivamente. El contenido de fibras totales fue mayor en tallos que en hojas mientras que en el caso de cenizas fue a la inversa. En base a la producción de materia seca aérea y contenido de proteínas, fibras y minerales, se concluye que quínoa puede ser un complemento forrajero para los animales que forman parte de la producción pecuaria de los Valles Calchaquíes.
