Energy and labour requirement of different tillage methods in oil seed rape production

On silty loam soil in western Slavonija, six different tillage methods were compared in oil seed rape production. Tillage methods were five nonconventional (reduced) systems and one conventional system as standard. Essential goal of investigation was to compare energy and labour requirement of each soil tillage method and also influence on achieved yield. Results of investigation showed that single pass of rotary cultivator integrated with drill achieved the lowest energy requirement as per hectare of 155.7 MJ/ha, as per tonne of yield of 59.0 MJ/t. Compared to conventional tillage it was 45.7 % and 51.7 % less energy. Comparison of tillage methods with respect to labour requirement showed that best results had been achieved by single pass of rotary cultivator integrated with drill. So, this combination required 1.25 h/ha which is 23.8 % less and 0.47 h/t which is 33.0 % less than conventional tillage. Four of five tested reduced tillage systems achieved better results in comparison to conventional tillage as with respect to energy requirement as with labour requirement.
