Abstract
This field experiment was designed to assess the vegetative and fruiting response of ‘Polka’ raspberry plants to partial rootzone drying (PRD), mulching and their combinations.
The experiment was conducted in Kosovo (Prishtina region) during 2014 in a raspberry orchard of 1 ha on first year planting.
Four levels of budget irritation were studied: 100% ET (control) lateral, two laterals (TL), side lateral (SL), and without irrigation (WI). Each treatment contained 10 plants, of which five plants per treatment were mulched to a 10-cm layer of wood chips (size 1-2 cm). Using a nested experimental design, data were analysed with ANOVA two-way with post hoc testing.
Irrigation had significant changes on shoot length, number of leaves, leaf surface and area, LAI, number of fruit, fruit diameter, fruit length, fruit weight and total yield.
It should also be stressed that mulching had significant changes in leaf surface and area, LAI, number of fruit and total yield.
PRD and mulching had a combined effect on leaf surface, fruit length and fruit weight.
Two laterals treatment gave higher values of these vegetative parameters compared to control and consequently to all other treatments while, the highest values of productive parameters were found in two laterals treatment, followed by normal irrigation (control), side lateral and lastly without irrigation.
