VIAL-ALARCON, Manuel Andrés  and  INOSTROZA FARINA, Juan. Atriplex nummularia (Lindl.) establecida en el secano del centro-sur de Chile. Siembra [online]. 2023, vol.10, n.1, e3985. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v10i1.3985.

Atriplex nummularia (Lindl.) is a shrub used as a strategic forage resource in arid and semi-arid livestock systems in summer. In 2019, two monitoring modules were created for this species in southern Chile; in the localities of Los Sauces (drylands, 37° south latitude) and Carillanca (dry central valley, 38° south latitude). Growth during 3 years (2019-2021) and forage quality of the material consumable by livestock were evaluated. Forage quality in summer was different between localities and was attributable to soil and climatic conditions. It is concluded that in Carillanca, a locality with higher rainfall and better soil quality, the highest growth in volume was recorded even when the cold period is extensive; in Los Sauces, however, despite average temperatures being better for the species (>10 °C), growth was lower, this being attributable to the soil conditions where the plantation was carried out (soil quality-site), together with the extent and severity of the dry period (summer and autumn).

Keywords : Atriplex nummularia; dryland; valley land; soil quality site.
