Three irrigation frequencies and four tillage systems were studied for two consecutive summer seasons (2002/03 and 2003/04) to test their effect on growth and yield of groundnut (Arachis hypogaea L.).The study was carried out in the Demonstration Farm of the Faculty of Agriculture and Natural Resources, University of Kassala at New Halfa, Sudan. The irrigation frequencies were 10, 15 and 20 days, and the tillage systems used were discing, ridging, harrowing and no-tillage. There were significant differences in the studied parameters due to irrigation frequency. Except for days to 50% flowering and shelling percentage, the to days frequency recorded higher values than 15 and 20 days frequencies. On the other hand, tillage system had significant effects on an tested parameters except l00-seed weight and shelling percentage. Disc ploughing gave higher values than the other tillage systems. The interaction between irrigation frequencies and tillage systems had significant effects on the studied parameters except days to 50% flowering, seed weight and shelling percentage. Ten days irrigation frequency with disc ploughing gave the highest yield and field water use efficiency. Key words: Groundnut; irrigation frequency; tillage; water use efficiency
