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.
