The experiment was raised at Gash Delta, for two seasons (2004/2005 and 2005/2006) and laid in a randomized complete block design with three replications. The objective was to evaluate the operation performance of two introduced tillage implements (scarifier and single-acting disc harrow) and their effects on weed control, soil moisture content and groundnut yield in comparison to the used traditional implement (2-blade disc plough). In terms of cost and operational performance, scarifying and harrowing resulted in lower tractor speed reduction percent, higher actual speed and rate of work, lower tillage operation time and cost compared to the traditional method. During both seasons and after tillage operation, scarifying and harrowing resulted in a significant reduction of weeds/square m compared to the traditional method. After manual weeding, significant reduction in weeds/square m was obtained with scarifying in the first season only. No significant differences were observed in soil moisture content within the crop rows as a result of the different tillage methods. Scarifying resulted in significantly higher yields of 2058 and 2688 kg/ha for the first and second season, respectively; followed by harrowing with respective values of 1460 and 1875 kg/ha compared to the traditional method that resulted in 878 and 1250 kg/ha for the respective seasons
