Abstract
The potato production in Croatia usually is organized on private farms on small fields.
One of regions, with the greatest potato production is Međimurje.
Most producers in this region plant potato more than two times on the same field or have very narrow crop rotation.
Most of soils in region show acidic reaction and usually farmers apply different materials like limestone or hydrated lime to reduce soil acidity, but without any lab control or recommendation.
Soils with this management practice show drastic common scab infections if soil moisture during tuber bulking is low.
The aim of research was to investigate the effect of immature chicken manure (20.0 t ha-1), hydrated lime (2.5 t ha-1) and foliar fertilizer application of Epsom salt (16% MgO, 13% S) (25 kg ha-1) on intensity of common scab infection on different cultivars (cv.
Courage and cv.
Desire). Trial results show that Desire had significant higher percent of infected tubers with higher intensity of infection than Courage. In the wet season 2004, there was no evident on scabies infection.
Differences between treatments are not significant but lime addition increases scab incidence.
By foliar application of Epsom salt, intensity of scab can be slightly reduced.
