Two years experiment with different soil tillage systems in production of winter barley and maize in Posavina

The paper presents results of the two years experiment in winter barley and maize production with four different soil tillage systems carried out in Western Slavonia, at agricultural company ” PK Nova Gradiska ” 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 56.07 L ha-1 (winter barley) and 62.93 L ha-1 (maize). The best energy saving system in winter barley was RT1 with 37.58 L ha-1 and RT2 with 36.30 L ha-1 in maize production. Soil tillage systems comparison regarding labour requirement unveiled that conventional tillage required 2.39 h ha-1 and 0.52 h Mg-1 in winter barley, while in maize production required 2.62 h ha-1 and 0.35 h Mg-1. The lowest labour requirement of 1.35 h ha-1 and 0.32 h Mg-1 obtained RT2 in winter barley, while in maize production RT2 achieved 1.48 h ha-1 and RT1 0.15 h Mg-1. The highest average yields were obtained by CT system in winter barley and RT1 in maize production, while the lowest yields were with RT1 in winter barley and RT3 in maize production.
