The article presents data on the photosynthetic activity of safflower (Cárthamus tinctórius) in the dry steppe zone of Northern Kazakhstan depending on the different time of sowing, seed rate and applied mineral fertilizer. During the years of research it has been found that crops sown on May 10 with a seed rate of 0.25 million viable seeds per hectare provided higher levels of photosynthetic activity. The positive effect of the mineral fertilizer applied during sowing influenced the activity of plant leaves.
