The quality and yield pOtato was depened to varietie, climate and soil fertility. Absence. or excess use of fertilizers reduces quality and yield potato. Afiled experiment was conducted to study the effects of foliar spary of .iron, zinc and manganes on yield potato ( Solanum Tuberosum ). This study was conducted in Eghlid research station at 2000 and 2001 years., Filed study was performed based on Completely Randomized Desigen ( CRD ) in factorial experiment with 18 treatments in 3 replication. The,treatments used were three levels of Feso4 and Zns04 ( 0,-0.25 and 2.5%) Clnd two levels' of Mnso4 ( 0 and 2.5%.) The foliar spray of fertilizers carried out at befor and after flowering. ---The resu'iis -indicated that application of micro nutrients increased yie'ld potato and ther is si'gnificant different (at 1,% ) in factors of experiment. The yiled of potato was increased by in carse oflevels use ofmicronutrient.The hight yield was produce by spary of Znso" at 2.5 % level that incrased 19 % yield than control tereatment.
