Abstract

Ugotavljali smo vpliv hitrosti setve (7, 9 in 11 km/h) s podtlačno pnevmatsko sejalnico na razdaljo med rastlinami v vrsti pri koruzi (Zea mays L.) in posledično na pridelek zelene mase ter pridelek zrnja. Poskus smo izvedli na srednje težkih tleh, na valovitem terenu, z nagibom v smeri vožnje v Globodolu na kmetiji Berus. Poskus je bil zasnovan v obliki naključnih ponovitev s štirimi ponovitvami znotraj bloka. Zaželena gostota setve je znašala 80.800 semen na hektar, pričakovana razdalja v vrsti pa je bila 16,5 cm. Pri hitrosti setve 7 km/h je bila povprečna razdalja med rastlinami v vrsti najbližje pričakovani razdalji. Pri tej hitrosti setve je bil najnižji odstotek dvojnih in praznih mest med rastlinami v vrsti ter najvišji odstotek rastlin znotraj območja od 0,5 × do 1,5 × pričakovana razdalja. Pri hitrosti setve 9 km/h je bil najvišji odstotek dvojnih in praznih mest ter najnižji odstotek rastlin znotraj želenega območja. Kljub manj natančni setvi pri višjih hitrostih 9 km/h in 11 km/h ni bilo razlik, v primerjavi z 7 km/h, ne v pridelku zelene mase, pridelku suhe snovi in pridelku zrnja pri 14 % vlagi.

Secondary title: ǂThe ǂeffect of different speed of sowing maize (Zea Mays L.) with vacuum sowing machine on yield of grain and silage
Secondary abstract: The aim of the present thesis is to establish the effect of the planting speed (7, 9 and 11 km/h) of a pneumatic vacuum planter on the distance between maize plants (Zea mays L.) in a planting row and, consequently, on the green fodder yield and the grain yield. The experiment was conducted on medium-textured soil at the Berus family farm in Globodol. The ground was undulating and inclined in the driving direction. The trial base consisted of random blocks with 4 various repetitions within each of them. The desired planting density was 80,800 seeds/ha, the expected distance between plants in a row was 16.5 cm. At the planting speed of 7 km/h, the average distance between plants came closest to the expected distance. At this planting speed, the percentage of doubled and empty spaces between plants in a row was the lowest, while the percentage of plants within the area of 0.5× - 1.5× expected distance was the highest. At the planting speed of 9 km/h, the percentage of doubled and empty spaces was the highest, while the percentage of plants within the desired area was the lowest. Despite lower planting accuracy at the higher speeds, i.e. at 9 and 11 km/h, there were no statistical differences compared to 7 km/h in the green fodder yield, the dry matter yield and the grain yield with a 14 % humidity.
