Summary: The dry land areas of Ethiopia account for more than 66.6% of the total land mass. In the dry land areas, the major constraint to agricultural production is moisture stress. The main causes of moisture stress are low and erratic rainfall, run- off losses due to poor water retention and infiltration and steep slopes. Tie- ridging has been found to be very effective in reducing runoff and soil erosion and in making more water available to the crop. However, the adoption rate by farmers has been low because it is tedious and time consuming to make them by hand. Recently, an animal drawn tie ridger has been developed to alleviate the problem of labour and time requirement. An on-farm experiment was thus carried out in order to verify the effectiveness of the tie ridger in combination with improved varieties. Two types of improved maize varieties: Katumani and Awassa-511 were tested in combination with tie ridging and fertilizer application. According to the results of the trials there were average yield increments of 22% and 28% due to the use of the tie ridger and improved varieties, respectively.
