Abstract Safflower ( Carthamus tinctorius L.) has unrealized potential as an alternative crop in many semiarid regions including central Argentina. Our objective was to relate how temperature and precipitation conditions with fall (5 June 2012 23 Apr. 2013) winter sowing (13 Aug. 20 affected phenology, yield, yield components, oil percent four eight spring‐type safflower accessions the region of Fall associated lower temperatures, higher precipitation, heat/moisture stress indices deficits than sowing. Rosette period lasted 55 d longer, stem elongation anthesis 30 longer However, advanced only few days duration postanthesis development comparable between regimes years. plants averaged 3,252 filled grains m –2 a grain 109.8 g , whereas 1,443 49.3 . Grain 35% accessions, but types had (22.0%) spring‐types (33.3%). In Argentina, we recommend it extended growing season terms preanthesis presented favorable climatic for development.
