Sažetak

Considering that primary tillage and soil preparation for the sowing of rapeseed is conducted during dry season, it is very important to choose the correct system of tillage for each area or soil type. This research aimed to determine the impact of soil tillage on yield and energy efficiency of rapeseed production under agro-ecological conditions of region Podravina. The study included two systems of tillage for rapeseed: 1) conventional tillage - mouldboard plough, rotary harrow integrated with seed drill; 2) reduced tillage - chisel plough, rotary harrow integrated with seed drill. The study was carried out on leached soil on sands in year 2017/2018 on a plot with a total surface area of 3.5 ha. Conventional tillage was carried out on one half of the plot (1.75 ha), and reduced tillage on the other half (1.75 ha). Fendt 716 Vario 118 kW, an allwheel- drive tractor, was used for all tillage operations. During all work operations, fuel consumption was measured by volumetric method and energy consumption was subsequently calculated. Yield was determined on each variant of tillage in three replications. The system of tillage did not have a significant effect on seed yield, oil content in seed and oil yield. Reduced tillage resulted in energy savings of 387 MJ ha-1, i.e. reduced fuel consumption by 10 l ha-1. Therefore, reduced tillage is more environmentally friendly due to lower CO2 emissions. From an economic point of view, a reduced cost of tillage is more profitable, as compared to conventional tillage, because a higher income of 282.00 kn ha-1, that is 3.42 %, has been achieved.
