Abstract:

Having emerged as a result of rapid industrialization since the early 20^th century, global warming can negatively affect natural resources, particularly water resources. Climate changes resulting from global warming threaten the viability of ornamental plant species used in urban landscaping. This study investigates the effects of drip irrigation on Berberis thunbergii ‘Atropurpurea Nana’. Between 2011 and 2012, for Berberis thunbergii ‘Atropurpurea Nana’ plant (P), two different irrigation levels (I₁ 100%, I₂ 75%), fertilizer regimes (F₁ with fertilizer, F₂ without fertilizer) and planting ranges (PR₁ 30 cm, PR₂ 45 cm) were tested. The first irrigation was made in 40 cm depth up to the farm capacity. The next regular irrigation (I₁ group) was sufficient to bring the existing humidity to farm capacity and I₂ until the existing water of the soil reaches the 75% of available water holding capacity. The greatest water consumption was in parcel PI₁ F₁ PR₁ and the lowest consumption was in parcel PI₂ F₂ PR₂. As irrigation level, fertilizer and planting range are effective on trials and 25% water limitation does not negatively affect the development of Berberis thunbergii ‘Atropurpurea Nana’, it is concluded that irrigation levels of 75% soil water holding capacity can enable important water savings. According to the results, landscape architecture projects should specify the drip irrigation method to achieve more efficient irrigation with available water resources and provide water savings.
