- Abstract
This study was conducted to determine the effects of humic acid and iron applications on seed yield, some plant characteristics and oil ratio of Remzibey-05 safflower cultivar under Harran Plain conditions in the 2011-2012 and 2012-2013 growing seasons. The experiment was carried out in randomized complete block split plots design with three replications. The main plots were humic acid (HA) applications (0, 60 g ha-1, 120 g ha-1, 180 g ha-1 ), and the sub-plots were iron (Fe) applications (0, 12.5 kg ha-1, 25 kg ha-1 and 37.5 kg ha-1 ). Humic acid was sprayed onto the leaves and iron was applied to the soil when the plants were leading the stage of 4-5 leaves. The highest seed yield, number of heads per plant and dry petal yield per plant were obtained from 120 g ha-1 humic acid and 12.5 kg ha-1 Fe applications. The highest number of seeds per head was obtained from 180 g ha-1 HA and 12.5 kg ha-1 Fe applications while biomass yield was from 60 g ha-1 HA and 25 kg ha-1 Fe applications. In conclusion; 120 g ha-1 humic acid and 12.5 kg ha-1 Fe should be applied to increase seed yield, number of heads per plant and dry petal yield per plant in safflower agriculture under semi-arid climate conditions.
