Pošlji prispevek (e-pošta) Artičoka (Cynara scolymus L.) kot prodajno zanimiva vrtnina v ekološki pridelavi zelenjave
Povzetek
Zeleno gnojenje ima pomebno vlogo pri ekološki pridelavi zelenjave kot vir dušika, a je problem v tem, da rastline namenjene temu zasedajo prostor v kolobarju več mesecev brez neposrednega dohodka. Artičoka (Cynara scolymus L.) daje oboje, tržni pridelek v obliki koškov in veliko organskih ostankov, ki se lahko zaorjejo kot zeleno gnojilo, torej igra dvojno vlogo kot tržna in pokrovna kultura. Prispevek opisuje vzorčno raziskavo kmetije, na kateri pridelujejo iz semen vzgojeno artičok kot enoletno kulturo v ekološkem kolobarju pridelovanja zelenjave za bučkami in vrtno solato. Artičoka je dala okrog 7 t ha-1 tržnih koškov in po pobiranju pustila na polju 50.3 t ha-1 sveže biomase, ki je uporabna kot podor. Bučke in vrtna solata, ki so v kolobarju sledile artičoki, so dale značilno večji pridelek, kadar so se ostanki artičoke vdelali v tla. Pozitivni učinek zelenega gnojenja na rodovitnost tal je bil ugotovljen še po pobiranju pridelka vrtne solate.
