An experiment was conducted out during 2009 to study the effect of spraying numbers (0, 2 and 4 ) of Alaska foliar fertilizer (N: 12, P2O5:12, K2O: 36, Fe: 0.05%, Cu: 0.005%, Mn: 0.03% , Zn:0.01% , B: 0.02% , Mo: 0.003% ) on growth and yield of 7 potato cvs. (Draga, Aladin, Elpaso, Kurado, Diseree, Provento and Red Brown). Factorial experiment included 21 treatments arranged in Random Complete Bloke Design (RCBD) with 4 replications. Results showed that foliar fertilizer had a significant effect on plant height, tuber weight and total yield. Potato cvs. differ in all studied parameters. High yields were obtained from Red Brown, Provento and Draga cvs. Interactions had a significant effect on the most studied parameters.
