Although safflower is considered a drought resistant crop, irregular distribution of precipitation and limited rain are the main risk factors for growing this crop in fields under dryland agriculture. This study presents the effects of water shortage and high temperature during stem elongation and branching on development and yield of safflower under non-irrigated conditions in Ankara (Turkey). Three years of results showed that plant height, number of heads per plant, head diameter, and yield were reduced drastically (from 74.4 to 48.2 cm; from 10.2 to 4.1 heads/plant; from 2.3 to 1.9 cm and from 218.9 to 48.4 kg/da, respectively) when the crop was subjected to limited rains. Consequently, supplementary irrigation must be applied during the specific stages of plant i.e. elongation and/or preflowering for ensuring the development of safflower under Ankara conditions.
