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 Slavonia, at agricultural company ”PK Nova Gradiška” in village Staro Petrovo Selo, located 150 km south-east from Zagreb (45° 10’ N, 17° 30’ 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.
