The effects of different dwarfing applications on yield and quality in Bursa siyahi fig (Ficus caric L.) trees

The study to specify the effects of different applications for dwarfing, fruit quality and yield on Bursa Siyahı (Black Bursa) Fig Trees was performed between 2014-2015 in the parcel of Department of Horticulture, Faculty of Agriculture, Adnan Menderes University. In order to create artificial dwarfing on the fig nursery trees; Prohexadione-Calcium, a giberellin acid inhibitor, was used as 125 and 250 ppm. In addition, nursery trees were planted on 30° angle with ground level and were grown by strapping to galvanized wires. Two different dose applications of curving+Pro-cal were used and there have been 6 different applications in total including the control. The fig nursery trees were planted 1x1.5 m intrarow and above-row in parcels where branch bending applicated and also 1x1 m intrarow and above-row in parcels where other applications made. Pro Ca applications were performed twice on vegetation period, by means of the period when new shoots are 5 cm tall on saplings. Morphological observations for determining of application effects on dwarfing, and pomological observations for determining applications effects on yield and quality were done. ın addition that phenological observations were done. It was revealed that in Pro Ca applications, where the highest values especially in node number, lateral branch number and the longest lateral branch length are, 23% in 250 ppm Pro Ca application and 43% in 125 ppm Pro Ca application more yield was obtained than the control group fig trees in terms of yield per tree without quality loss.
