Economic efficiency of non-conventional soil tillage systems in oil seed rape and winter barley production

The paper presents results of the two years experiment in oil seed rape ( Brassica napus L) and winter barley ( Hordeum vulgare L) production with five different soil tillage systems carried out in Western Slovenia, at agricultural company "PK Nova Gradiska" in village Staro Petrovo Selo, located 150 km south- east from Zagreb (45degrees10′N, 17degrees30′E). Energy requirement comparison showed that CT system in both crops production had the highest fuel consumption of 47.36 L ha -1 (oil seed rape) and 50.93 L ha -1 (winter barley). Also, the best energy saving system in both crops production was RT1 with 32.60 L ha -1 in oil seed rape and 33.03 L ha -1 in winter barley production, which is decrease of 31.2% and 35.1% respectively. Soil tillage systems comparison regarding labour requirement unveiled that conventional tillage required 2.04 h ha -1 and 0.45 h Mg -1 in oil seed rape, while in winter barley production required 2.14 h ha -1 and 0.52 h Mg -1. The highest average yields were obtained by CT system in oil seed rape (3.85 Mg ha - 1) and RT3 in winter barley production (4.42 Mg ha -1), while the lowest yields were with RT1 in both crops production, 3.21 Mg ha -1 in oil seed rape and 3.71 Mg ha -1 in winter barley.
