This study was carried out during the two successive summer seasons of 2008 and 2009 at the Experimental Farm of Environmental Studies and Research Institute, Minufiya University, Sadat City, to evaluate the influence of the yield and yield attributes of groundnut to four gypsum applications (0, 250, 500 and 750 kg/fed) in a split-plot design  using (Giza-kaem, Giza-4 and Giza-5) peanut cultivars of four replications. Other nutrients wereapplied uniformly. The results from this experiment show that adding gypsum with the rate of 500 kg / fed increased significantly pods weight / plant, 100- seed weight, shelling %, oil seed % total protein and pod yield / plant.  0n the other hand Giza 5 cultivar was superior than Giza 4 and Giza kaem in plant height, number of branches / plant, number of pods / plant, 100-pod weight, shelling %  oil seed %, total protein  and pod yield kg /fed.  The interaction between gypsum frequency and cultivars had significant effect on pod yield / fed. The highest pod yield / fed were produced by using Giza 5 and gypsum with the rate of 500 kg / fed. Finally, it could be concluded that the superior interaction treatments concerning yield and its components were the cultivated peanut plants Giza 5 variety when received 500 kg gypsum/fed with all other treatments.
