Optimal irrigation regime of raspberry production using drip irrigation system
Abstract
Testing of irrigation regimes on alluvial soil under raspberries production are conducted on an experimental field"Kosovo", of 0.11 hectares surface, set in a representative part of a larger productive plantations in the village near Arilje Mirosaljci. Willamette raspberry cultivar was grown on a flat surface, at an altitude of 354 meters in row breeding form, under standard conditions of agricultural technology except soil water regime.Surface irrigation was used where is applied drip irrigation metohod on 64 basic plots with different variants of studies conducted in 4 replicates. Natural water regime (Wo), and different variants of irrigation water regime (Wi), have resulted in different raspberry yields in the range from 0.70 to 2.38 kg / m2.Natural water regime (Wo) and its dépendance on different factors such as: -> irrigation regime (V) -> irrigation water quantity (Nz) -> distance between drippers (R) -> water flow (q) -> irrigation time (t), within irrigation water regime (Wi), has been influenced on fresh raspberries yield (Y).The best irrigation regime for raspberries production on alluvial soil of arilje vineyards is irrigation regime V2 - which is representing irrigation practice from flowering growth stage to the end of growing seasons offspring shoot, with the distance between drippes on the lateral of R = 0,50 m, with water flow of qi = 2,3 1/hour, irrigation time of one hour and with irrigation water quantity of 2 mm/day.
