Abstract: Mouldboard plough is primary tillage implement used in conventional tillage. It is one of the equipment that needs high draft power and specific energy. Predicting the draft power and specific energy requirement of mouldboard ploughs depending on technical properties of the plough, the physico-mechanical properties of the soil and the working conditions before the soil tillage will be useful in terms of energy saving. This study aimed at predicting draft power and specific energy requirement of cylindroid mouldboard ploughs in medium heavy soil conditions. For this purpose prediction equations were developed to calculate draft power and spesific energy requirement of mouldboard plough. The prediction equations were developed based on dependent variables such as soil parameters including penetrometer resistance, bulk density and moisture content, working witdh, working depth, forward speed and field capacity. Equation 1 for predicting the draft power in medium heavy soil conditions and Equation 2 for predicting of the penetrometer resistance of medium heavy soil working with cylindroid mouldboard ploughs were used. The draft power obtained from Equation 3 was rated to the field capacity to predict specific energy requirement of mouldboard plough. As a result, a basic Equation 4 for predicting the specific energy requirement of the mouldboard plough was obtained. To test the reliability of the developed prediction equations, the regression coefficients between the results from prediction equations and some other research results were determined. The study showed that draft power and specific energy requirement could be successfully predicted by the prediction equations with good accuracy when working in medium heavy soil condition with cylindroid mouldboard ploughs. The regression coefficients of relationship between predicted and measured draft power of mouldboard ploughs were varied from 0.948 to 0.996. The regression coefficient of relationship between predicted and measured specific energy requirement of mouldboard ploughs was 0.924.
