In the era of increasingly intensive climatic changes irrigation is becoming very important way of increasing crop yields and improving its quality. Like elsewhere in the developed world, drip irrigation is predominant in Slovenia. Such an irrigation is the most efficient and considering environmental protection the most suitable one. Plants get the precise dosage of water needed to the root area through the pipes using emitters.
In this thesis the design of a small irrigation system in apple orchard in Slovenska Bistrica area is described. Legal basis and permits required for construction are presented. Based on the data on ground, plants, climate and precipitation maximum water demands of plants are calculated. In relation to the demanded irrigation quantity a small reservoir that is filled by precipitation and abstraction of water from the Devina stream is designed. Based on water demands emitters, pipes, armature, filters and pump are selected.
Irrigation parameters are calculated and, with the CROPWAT 8.0 program, irrigation schedules are prepared.
