Yield of artichoke leaves in regard to the agroecological conditions of cultivation

Abstract

Results of the two year research of the effect of agro ecological conditions of cultivation on the yield of artichoke leaves are analised. Research was carried out in 2004 and 2005 on two locations in South Banat region (Kačarevo – soil type chernozem and Pančevo – soil type marsh dark soil) and on one location in Western Serbia (Gorobilje – brown forest soil type). Higher amount of precipitation and higher sum of temperatures during vegetation period in 2004 compared to 2005 as well as thirty year average (1970-2000) probably caused higher yield of leaves in year 2004. Soil type also had considerable influence on the yield of artichoke leaves so in both research years the greatest total yield was determined on soil type chernozem and the lowest on brown forest soil. In regard to the time of collecting, the greatest yield in both research years and on all three locations was in the third cut and the lowest in the first cut.

Analizirani su rezultati dvogodišnjeg ispitivanja uticaja agroekoloških uslova gajenja na prinos lišća artičoke. Istraživanja su sprovedena u toku 2004. i 2005. godine, na dva lokaliteta u Južnom Banatu (Kačarevo – zemljište tipa černozem i Pančevo – zemljište tipa ritska crnica) i na jednom lokalitetu u Zapadnoj Srbiji (Gorobilje – zemljište tipa gajnjača). Veća količina padavina i veća suma temperatura u toku vegetacionog perioda u 2004. godini u odnosu na 2005. godinu, kao i u odnosu na tridesetogodišnji prosek (1970 -2000) verovatno su uslovili veći prinos lišća u 2004. godini. Tip zemljišta imao je značajan uticaj na visinu prinosa lišća artičoke, tako da je u obe godine istraživanja ukupan prinos bio najveći na zemljištu tipa černozem, a najmanji na zemljištu tipa gajnjača. Gledano po vremenu sakupljanja, najveći prinos bio je u obe godine istraživanja i na sva tri lokaliteta u trećem otkosu, a najmanji u prvom.
