INVESTIGATION OF THE IRRIGATION POSSIBILITY OF ILEX AQUIFOLIUM L. PLANTS BY DRIP IRRIGATION

This study was conducted to determine the water consumption of the most frequently used ornamental plant species in landscape architecture and the required irrigation water. This study aimed to investigate the effect of different trial samples on Ilex aquifolium L. plant. Between the years of 2011- 2012, two different irrigation levels (I1: 100%, I2: 75%), fertilizer levels (F1: with fertilizer, F2: without fertilizer) and planting distances (PD1:30 cm, PD2:45 cm) were used. The first irrigation was made up to the field capacity the soil water content in 40 cm depth. The next regular irrigation was made on I1 treatment in an amount that could bring the current humidity to field capacity and I2 treatment reached the 75% of available water holding capacity the current water of the soil. In the study, the highest and the lowest water consumptions were in PI1F1PD1 and PI2F2PD2 treatments, respectively. The results show that the relationship between irrigation fertilizer level and plant development of Ilex aquifolium L. are significant; however, there is no notable relationship between planting range and plant development. As 25% water limitation did not negatively affect the development of Ilex aquifolium L., it was found that irrigation levels of 75% soil water holding capacity can enable important water savings.
