20.500.12556/DKUM-43697 Vpliv razlicnih nacinov obdelave tal in setve na porabo goriva in pridelek koruze Influence of different soil tillage and sowing on fuel consumption and maize yield V letu 2013 smo na poskusnem polju v Mali vasi opravili poskus z namenom, da bi ugotovili, kako razlicna obdelava tal in setev s sejalnicami z razlicnim nacinom delovanja vplivajo na pridelek in porabo goriva. Na štirih poskusnih poljih smo predsetveno pripravo tal opravili s predsetvenikom ali vrtavkasto brano, nato smo opravili setev z dvema razlicnima sejalnicama. Prva je pnevmatska nadtlacna, druga pnevmatska podtlacna. Pri vseh opravilih smo merili porabo goriva in casa, pri setvi pa še porabo semena. Po 14 dnevih smo opazovali vznik. Jeseni smo izmerili pridelek na vseh poskusnih parcelah in izmerili vlago zrnja koruze. Zbrali smo tudi vremenske podatke za celo leto. Ugotovili smo, da se predsetvena priprava tal opravi hitreje in bolje z vrtavkasto brano v primerjavi s predsetvenikom poleg tega pa prihranimo tudi gorivo. Setev s podtlacno sejalnico je bolj natancna, poraba semena pa je nižja v primerjavi z nadtlacno sejalnico. Pridelek je bil najvišji na poskusni parceli V1 (6596,8 kg SS/ha), kjer smo tla obdelali z vrtavkasto brano in sejali s podtlacno sejalnico. In our research which was done in 2013 we tried to determine with experimental field in the village of Mala was how different soil tillage and sowing the seed drills with a different mode of action affecting the yield and fuel consumption. We prepared four experimental fields with rotary harrow or seed bed combination and then we used two different sowing seed drills. The first was the pneumatic overpressure and the second pneumatic vacuum pressure. At all tasks we measured fuel and time consumption and duration seeding we also measured seed consumtion. After 14 days we observed the growth of plants. In autumn we measured yield at all experimental plots and moisture of corn grain. We also collected weather data for the whole year.We have found that the pre-sowing soil preparation was carried out more quickly and effectively with rotary harrow in comparison with seed bed combination. Also this method saves the fuel. Using the seed drill vacuum is more accurate, consumption of seeds is lower in comparison with the seed drill overpressure. The highest yield was in the experimental plot V1, where the soil was treated with a rotary harrow and sown with vacuum seed drill.
