dc.description.abstractThe paper presents results of one year experiment in winter wheat production with three different soil tillage systems carried out in Slavonia, at fields of agricultural enterprise Hana Našice d.o.o, location Lila. Test crop was winter wheat, variety Renan. Tillage systems were: conventional, conservation and no-till. Energy requirement comparison showed extraordinary expensiveness of conventional tillage with specific consumption of 46.6 L ha-1 and 8.19 L Mg-1 of diesel fuel. Conservation tillage I system required 29.8 L ha-1 and 4.92 L Mg-1, which is 36.1 % less energy per hectare and 40.0 % less energy per ton. Conservation tillage II required 18.9 L ha-1 and 2.85 L Mg-1, which is 59.4 % less energy per hectare and 65.2 % less energy per ton. The most energy saving soil tillage system is no-till with fuel consumption of only 6.2 L ha-1 0.92 L Mg-1 of diesel fuel or 86.7 % less energy per hectare and 88.8 % less energy per ton than conventional system. Soil tillage systems comparison regarding labour requirement unveiled that conventional tillage required 1.95 h ha-1 and 0.34 h Mg-1, while conservation tillage I required 1.29 h ha-1 and 0.21 h Mg-1 or 33.8 % and 37.9 % less labour requirement than conventional tillage system respectively. Conservation tillage II required 0.74 h ha-1 and 0.11 h Mg-1 or 62.3 % and 67.6 % less labour requirement. No-till required only 0.32 h ha-1 and 0.05 h Mg-1 which is 83.8 % and 86.3 % less than conventional tillage system. The lowest yield of 5.69 t ha-1 achieved conventional tillage, while the highest yield of 6.73 t ha-1 achieved no-till.en
dc.description.abstractU radu su prikazani rezultati jednogodišnjeg eksperimenta proizvodnje ozime pšenice različitim sustavima obrade tla, provedenim na površinama imanja Njive d.o.o. u mjestu Lila, pokraj Našica. Test usjev je bila ozima pšenica, varijetet Renan. Primjenjeni sustavi obrade tla bili su kako slijedi: konvencionalni, konzervacijski i direktna sjetva bez obrade. Usporedba sustava obrade prema utrošku energije pokazuje svu rastrošnost konvencionalne obrade tla sa specifičnom potrošnjom goriva od 46.6 L ha-1 i 8.19 L Mg-1. Konzervacijska obrada I je iziskivala 29.8 L ha-1 i 4.92 L Mg-1, odnosno 36.1% i 40.0 % manje energije respektivno. Konzervacijska obrada II je trebala 18.9 L ha-1 i 2.85 L Mg-1, što je 59.4 % i 65.2 % respektivno manje energije od konvencionalne obrade. Najveće uštede energije postignute su direktnom sjetvom bez obrade ili no-till sustavom koji je trošio svega 6.2 L ha-1 i 0.92 L Mg-1 diesel goriva, odnosno 86.7% i 88.8% respektivno manje od konvencionalne obrade. Usporedba različitih sustava obrade tla prema utrošku ljudskog rada pokazuje da konvencionalna obrada troši 1.95 h ha-1 i 0.34 h Mg-1, konzervacijska obrada I troši 1.29 h ha-1 i 0.21 h Mg-1 ili 33.8% i 37.9% respektivno manje od konvencionalne obrade. Konzeravacijska obrada II iziskivala je 0.74 h ha-1 i 0.11 h Mg-1, odnosno 62.3% i 67.6% respektivno manje. Direktna sjetva trebala je svega 0.32 h ha-1 i 0.05 h Mg-1, što je 83.8% i 86.3% respektivno manje od konvencionalne obrade. Najmanji urod od 5.69 t ha-1 postignut je konvencionalnom obradom, dok je najveći urod od 6.73 t ha-1 postignut direktnom sjetvom bez obrade.sr
