Abstract
Namen raziskave je bilo ugotoviti razlike v pridelku in kakovosti čebulic (glavic česna) pri sajenju dveh sort česna v dveh različnih terminih sajenja. Poskus smo izvedli na Laboratorijskem polju Biotehniške fakultete v Ljubljani, od novembra 2017 do julija 2018. V poskus smo vključili špansko sorto 'Gardos' in slovensko avtohtono sorto 'Ptujski spomladanski'. Poskus smo zasnovali z jesenskim in spomladanskim terminom sajenja v 5-ih ponovitvah za vsako sorto. Pred sajenjem smo na naključnih 11-ih vzorcih sadilnega materiala izvedli meritve mase in premera glavic ter števila strokov v glavici. Po končani rastni dobi smo prešteli število preživelih rastlin in izračunali delež preživetja, ki je pri obeh sortah znašal 89 %. Pridelek smo pobrali julija, ga stehtali in po enem mesecu sušenja, izvedli enake meritve glavic kot na semenskem materialu. Ugotovili smo, da je bil največji pridelek dosežen pri jesenskem terminu sajenja pri sorti 'Gardos' (13,0 t/ha), sledi pridelek iste sorte spomladanskega termina sajenja (12,6 t/ha). Manjši pa je bil pridelek sorte 'Ptujski', 7,6 t/ha pri jesenskem in 6,0 t/ha pri spomladanskem terminu sajenja. Ugotovili smo razlike v masi glavic in številu strokov v glavici na termin sajenja. Vpliv na maso glavic česna je imel le jesenski termin sajenja, saj se je masa glavic glede na sadilni material, v tem terminu sajenja zmanjšala za 20 % pri sorti 'Gardos' in za 25 % pri sorti 'Ptujski spomladanski'. Termin sajenja je vplival tudi na število strokov v glavici česna. Glede na sadilni material so imele glavice sorte 'Gardos' 35 % manjše število strokov pri jesenskem terminu. Glavice sorte 'Ptujski spomladanski' pa 38 % manjše pri spomladanskem terminu sajenja.

Title:Yield and quality of garlic bulbs (Allium sativum L.) regarding to the planting date
Abstract:
The purpose of the research was to determined, the difference in yield and bulb quality of two different varieties of garlic regarding the two different planting dates. The experiment was carried out at the Laboratory Field of the Biotehnical Faculty in Ljubljana, between November 2017 and July 2018. In the experiment we tested variety 'Gardos' and domestic Slovenian variety 'Ptujski spomladanski'. The experiment was performed in two planting date (autumn and spring), in 5 repetitions. Before planting, we randomly selected 10 bulbs on which the following quality characteristics of garlic bulbs were measured: the mass of garlic bulbs, the diameter of the bulbs and the number of cloves in each bulb. On spring, the number of survived plants were counted and at both varieties the survived rate was 89%. The yield was harvested in July. The garlic was then left to dry for about one month. After that, 10 randomly bulbs were selected from each repetition and measured in the same manner as the planting material. We established that the highest yield was at variety 'Gardos' planted in autumn (13.0 t/ha), followed by the same variety, planted in spring (12.6 t/ha). Lower yield was recorded at variety 'Ptujski spomladanski' (7.6 t/ha in autumn and 6.0 t/ha in spring). Some differences in quality characteristics regarding the planting dates were also showed. Autumn planted date influenced the bulb mass, which was decline for 20% at variety 'Gardos' and for 25% at variety 'Ptujski spomladanski' relative to planting material. Regarding the planting material, also the number of cloves was lower in garlic bulbs of variety 'Gardos' (for 35%) from autumn planting date and at variety 'Ptujski spomladanski' (for 38%) from spring planting date.
