Effect of different organic fertilizer on yield and yield properties in safflower (Carthamus tinctorius L.) in calcareous soil conditions

This research was conducted to investigate the revealing with humic acid of phosphorus absorbed in calcareous soil conditions of Sarikaya district of Yozgat and the effects of fertilizer containing organomineral on yield and yield properties of Balci safflower (Carthamus tinctorius L.) varieties during the growing period in 2014. Three different plant nutrients (Humic acid, Organomineral Fertilizer, Humic Acid + Organomineral Fertilizer) were used in the experiment conducted in randomized block design with three replications. According the results of this research; the highest values in plant height, branch number/plant, capsule number/plant, seed number/capsule, thousand seed weights, seed yield, oil content, and protein content were recorded as 92.67 cm, 14 number, 21 number, 46.8 number, 45.967 g, 211.333 kg/da, 33.954%, and 16.357%, respectively. The significant increase in the yield and quality properties of cv. Balci was determined when used humic acid together with organomineral fertilizer. The use of humic acid in calcareous soil conditions was observed positive contributions.
