Summary:

Global warming and climate change which have resulted from the rapid industralization process from the beginning of the 20th century, have created negative impacts on natural resources and especially water resources in Turkey as well as the rest of the world. Climate changes which have appeared as a global warming creates a threat against the life functions of plants usedd in open urban green areas.

In the scope of the study, two different plant species (B1: Berberis thunbergii ‘Atropurpurea Nana’, B2: Ilex aquifolium), two different irrigation level (I1: % 100, I2: % 75), two different fertilizer level (G1:fertilized, G2: unfertilized ) and two different planting distance (DA1: 30 cm, DA2: 45 cm) used for a period of a year between 2011-2012 in order to investigate water consumption of plants and possibilities for water conservation.

Irrigation water amount at the trail plots are respectively 119.15-98.25 mm for B1 subject in 2011 and 166.49-124.87 mm in 2012; 98.25-81.05 mm for B2 subject in 2011 and 166.49-124.87 mm in 2012. Seasonal water consumption between 109.00-73.11 mm for B1 subjects in 2011 and 184.44-130.86 mm in 2012; 76.02-60.13 mm for B2 subjects in 2011 and 130.83-102.60 mm in 2012.

In both years, the highest water consumption for B1 subjects was observed in the B1I1G1DA1 parcel and for B2 subjects in the B2I1G1DA1 parcel. In the study, it was concluded that while irrigation level, amount fertilization and planting distance were effective on the growth of B1, for B2 only planting distance was ineffective.

At the end of the study the data obtained from the study it is suggested that drip irrigation method should be preferred in landscape architecture planting applications in order to do more efficient irrigation with existind water resources and provide water conservation. Additionally, irrigation efficient plants would provide ecological and economic advantages in the long run.
