Abstract
Ovaj istraživački rad fokusira se na važnost pravilnog izbora skidača viška sjemena u procesu sjetve suncokreta pomoću OLT pneumatske sijačice. Kroz analizu različitih pozicija skidača, istraživanje pruža detaljan uvid u njihov utjecaj na raspored sjemena tijekom sjetve. Utvrđeno je da raznoliki položaji skidača značajno utječu na prosječan razmak između zrna sjemena. Položaj označen brojem 15, 17 i 18 rezultira većim razmakom između sjemenki, dok su pozicije 20, 23 i 25 dovele do smanjenja prosječnog razmaka. Posebno značajan je položaj skidača 17, koji pokazuje minimalno odstupanje od teoretski optimalnog razmaka, svega +0,17%. Osim toga, brzina sijačice od 6 km/h ima ključnu ulogu u postizanju željenog razmaka između sjemenki. Sijačica je opremljena mehanizmom za uklanjanje viška sjemena, ključnim faktorom za postizanje željenog razmaka između sjemenki. Rezultati istraživanja ističu važnost pažljivog odabira položaja skidača kako bi se optimizirala sjetva suncokreta, s ciljem unapređenja produktivnosti i kvalitete poljoprivredne proizvodnje.
Abstract (english)
This research focuses on the importance of proper selection of seed eliminator in the sunflower seeding process using the OLT pneumatic planter. Through an analysis of different positions of the seed eliminator, the research provides a detailed insight into their impact on seed distribution during sowing. It has been found that various positions of the seed eliminator significantly influence the average spacing between seed grains. Positions marked as 15, 17, and 18 result in wider spacing between seeds, whereas positions 20, 23, and 25 have led to a reduction in the average spacing. Particularly noteworthy is the position of the seed eliminator at 17, which shows minimal deviation from the theoretically optimal spacing, merely +0.17%. Furthermore, the sowing machine's speed of 6 km/h plays a pivotal role in achieving the desired seed spacing. The sowing machine is equipped with a mechanism to remove excess seeds, a crucial factor in attaining the desired seed spacing. The research results underscore the importance of carefully choosing the seed eliminato's position to optimize sunflower seeding, aiming to enhance agricultural productivity and quality.
