Evaluation of agronomic variables in the cultivation of goldenrod (Solidago chilensis Meyen) in the Argentine humid pampas

Goldenrod (Solidago chilensis) is a perennial herbaceous species native to Argentina. Even though it has important medicinal properties and potential ornamental value, the species is not produced in the Humid Pampas. We evaluated the effect of two sowing densities (71 500 and 143 000 plants.ha-1, during 2013-2014 season) and two sowing dates (early sowing in September and late sowing in November, during 2014-2015 season) on phenology, morphometric characters and dry matter yield of two harvests per cultivation cycle. Plant density did not affect phenology or yields of both harvests, but lower plant density reduced main stem length and increased main inflorescence length and number of basal branches. Early sowing lengthened the vegetative and reproductive growth stages and increased main stem length, number of inflorescences, number of basal branches and yields of the first and second harvest. In both seasons, the first harvest produced higher yields. Sowing in September with a density of 71500 plants.ha-1 and a single harvest per cycle are recommended management practices for cultivation of goldenrod in the region.
