Abstract
Istraživanje je provedeno s ciljem utvrđivanja kvalitete sjetve korištenjem različitog sjetvenog aparata. Kvaliteta sjetve ocijenjena je na temelju ostvarenog razmaka zrna unutar reda, vremena nicanja i gustoće sklopa te prinosa. U istraživanju su korišteni mehanički sjetveni aparat s vodoravnom pločom (OLT MSK 2) te pneumatski aparat s podtlakom (INO Becker Aeromat A). Brzina sjetve određena je prema eksploatacijskim karakteristikama pojedine sijačice i brzinama kojima se sjetva provodi na gospodarstvima uključenim u istraživanje. Pneumatska sijačica ostvarila je veći radni učinak zbog veće brzine sjetve i radnog zahvata, kao i bolju preciznost u radu (95% točno položenih zrna u redu) i ravnomjernije nicanje. Prinos suhog zrna identičan je kod oba sjetvena agregata. Istraživanjem je utvrđena bolja učinkovitost i kvaliteta sjetve korištenjem pneumatske sijačice iako uz dobru podešenost i mehanička sijačica može ostvariti zadovoljavajuće rezultate.
Abstract (english)
The research was conducted with the aim of determining the quality of sowing using a different seed metering unit. Sowing quality was evaluated based on the achieved in-row seed spacing accuracy, emerging time, final plant density per unit area and yield. A mechanical seed drill with a horizontal plate (OLT MSK 2) and a pneumatic overpressure seed drill (INO Becker Aeromat A) were used in the research. The sowing speed was determined to the operating characteristics of each seeder and the speeds which are usual for sowing maize on farms included in the research. The pneumatic seed drill achieved higher work performance due to higher sowing speed and working width, as well as 95% of in-row spacing accuracy and more uniformly emerging. The yield of dry grain is identical with both seed drills. The research has determined better efficiency and quality of sowing by using pneumatic seed drill, although with a properly setting, a mechanical seed drill can achieve satisfactory results.
