Potato productive properties under different ecological conditions in Serbia

Abstract

The two-year study with nine potato cultivars: Adora, Jaerla, Cleopatra Latona, Liseta (early to medium-early cultivars) and Frisia, Kondor, Desiree and Morene (medium-late to late cultivars) was carried out in three locations: Zemun, Guča and Srbobran. The field trials were set up under different ecological conditions and on different soil types: slightly calcareous chernozem at 100 m above the sea level in Zemun, then on pseudo-gley at 370 m above the sea level in Guča and on chernozem at 86 m above the sea level in Srbobran. Mean monthly temperatures and precipitation were observed during the vegetation season. At the end of the vegetation season, the total yield of tubers and yield of marketable potatoes including all healthy and non-damaged tubers heavier than 70 g were examined. In addition, the average number of tubers per plant and the average tuber weight were dvaluated. Average yields achieved in 2001 were significantly higher than yields obtained in 2000. The highest total yield was achieved with the late potato cultivar Morene in the location of Zemun in 2001. The highest yield of marketable potatoes was detected in the cultivar Cleopatra in Zemun in 2001. The highest average number of tubers per plant was found for the cultivars Desiree, Morene and Latona.

U tri lokacije u Srbiji: Zemun, Guča i Srbobran, tokom 2000. i 2001. godine izvedeni su ogledi sa devet različitih sorti krompira: Adora, Jaerla Cleopatra, Latona, Liseta iz grupe ranih do srednje ranih sorti, kao i Frisia, Kondor, Desiree, Morene iz grupe srednje kasnih do kasnih sorti. Postavljeni su poljski ogledi u tri različite lokacije sa tri različita tipa zemljišta: na slabokarbonatnom tipu černozema na 100 m nadmorske visine u Zemunu, zatim na pseudogleju na 370 m nadmorske visine u Guči i na zemljištu tipa černozem na 86 m nadmorske visine u Srbobranu. Srednje mesečne temperature, kao i suma padavina praćene su tokom vegetacionog perioda. Na kraju vegetacije utvrđene su sledeće produktivne karakteristike: ukupan prinos, prinos tržišnih krtola, koje uključuju zdrave, neoštećene krtole teže od 70 grama, prosečan broj krtola po biljci, prosečna masa krtola kao i veličina krtola. U 2001. godini ostvaren je značajno viši prinos krompira u svim lokacijama u odnosu na prinose ostvarene u 2000. godini. Apsolutno najviši prinos ostvarila je sorta Morene u Zemunu 2001. godine, dok je u istoj godini najviši prinos tržišnih krtola postigla sorta Cleopatra. Najveći broj krtola po biljci je utvrđen kod sorti Desiree, Morene i Latona.
