Abstract

Poskus smo izvedli z namenom, da bi ugotovili, kako različni načini zasnove posevka (direktna setev/sadike z različnim številom rastlin v koreninski grudi) zimskega luka vplivajo na kakovost in količino pridelka. Poskus je potekal od 17. februarja 2017, ko smo posejali semena v gojitvene plošče, do 25. julija v steklenjaku in plastenjaku na Laboratorijskem polju Biotehniške fakultete v Ljubljani. V poskus smo vključili dva načina zasnove posevka: direktna setev v tla (setev povprek in setev v vrste) in dva načina zasnove posevka preko vzgoje sadik s koreninsko grudo (sadika z eno rastlino in sadika s tremi rastlinami). Rezultati poskusa so pokazali, da se je največ listov razvilo (6,3) pri zimskem luku, kjer smo posevek zasnovali s sadikami z eno rastlino, najmanj (4,1) pri direktni setvi povprek. Pri zasnovi posevka s sajenjem sadik z eno rastlino smo dosegli povprečno višino 88 cm, medtem ko je zimski luk zasnovan z direktno setvijo povprek dosegel povprečno višino 66,4 cm. Poleg števila listov je pri določitvi časa pobiranja pomembna tudi dolžina lažnega stebla, ki naj po priporočilih ne bi bila manjša od 7-10 cm. V našem poskusu so v poprečju najnižje lažno steblo dosegle rastline, kjer smo posevek zasnovali s setvijo povprek (17,6 cm) in najvišjo pri zasnovi posevka s sadikami z eno rastlino (25,5 cm). Količina pridelka je bila najmanjša pri zasnovi posevka s setvijo v vrste (16,7 t/ha) in največja pri sajenju sadik s tremi rastlinami na sadilno mesto (44,9 t/ha). S pridobljenih rezultatov lahko zaključimo, da najkakovostnejši pridelek pridelamo s sodobnim načinom zasnove posevka preko sajenja sadik z eno rastlino.

Secondary title: Comparison of different crop designing methods of welsh onion (Allium fistulosum L.) on the yield quantity and quality
Secondary abstract: The aim of our experiment was to determine how the different methods of designing (direct sowing/seedlings with different number of plants per cell) of Welsh onion (Allium fistulosum L.) effect on yield quantity and quality. The experiment started on February 17th, 2017, when seeds were sown into the plug trays, until July 25th, 2017 in a glasshouse and continued in a plastic greenhouse on Laboratory field at the Biotechnical Faculty in Ljubljana. We included two methods of crop design into experiment: direct sowing in the soil (sowing across and sowing in rows) and two ways of designing the crop through cultivation of seedlings with plugs (seedlings with 1 plant and seedlings with 3 plants per plug). The results of the experiment showed that the most leaves were developed (6,3) when the crop was planted with seedlings with 1 plant, and the least (4,1) at direct sowing across. With the design of the crop by planting seedlings with 1 plant, we reached an average height of 88 cm, while designed with direct sowing across reached an average height of 66,4 cm. The length of the false stem is also important for determining the harvesting time, which should not be less than 7-10 cm according to the genreal recommendations. In our experiment, on average, the lowest false stems reached plants where the crop was design with direct sowing across (17,6 cm) and the highest in the design of a crop with seedlings with 1 plant (25,5 cm). The lowest yield was in the design of the crop with direct sowing across (16,7 t/ha) and the highest in planting seedlings with 3 plants per plug (44,9 t/ha). From obtained results we can conclude that the best quality crop is produced by modern method od designing the crop through planting seedlings with one plant.
