Winter wheat production using conventional, conservation and no-till system

The paper presents one year experiment results in. winter wheat production with three different soil tillage systems carried out in Slavonia, at fields of agricultural enterprise Hana Nasice 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 39.38 kg ha(-1) and 6.07 kg t(-1) of diesel fuel. Conservation tillage I (B) system required 34.06 kg ha(-1) and 5.53 kg t(-1), which is 13.5 % less. Conservation tillage II (C) required 10.86 kg ha(-1) and 1.60 kg t(-1) which is 72.4 % less energy per hectare and 73.6 less energy per ton. The most energy saving soil tillage system is no-till with fuel consumption of only 5.50 kg ha(-1) and 0.81 kg t(-1) of diesel fuel or 86.7 % less than conventional system. Soil tillage systems comparison regarding labour requirement unveiled that conventional tillage (A) required 2.01 h ha(-1) and 0.32 h t(-1) while conservation tillage 1 (B) required 1.54 h ha(-1) and 0.25 h t(-1) or 23.83 % and 21.87 % less labour requirement than conventional tillage system respectively. Conservation tillage II (C) required 0.43 h ha(-1) and 0.06 t(-1) (r or 78.61 % and 81.25 % less labour requirement. No-till required only 0.43 h ha(-1) and 0.06 h t(-1) which is 78.61 % and 81.25 % less than conventional tillage system. No-till system enabled saving of 115,40 E ha(-1). The lowest yield of 6.16 t ha(-1) achieved conservation tillage I (B), while the highest yield of 6.82 t ha(-1) achieved conservation tillage II (C).
