Actual yields of cumin plant harvested by farmers are at level much below attainable yield potential. Among many growth factors zinc and ferrous was recognized as one of main limiting factors of crop growth and yielding. In order to study the effects of zinc and iron foliar application on yield, yield of cumin (Cuminum cyminum), with factorial experimental in completely randomize block design with three replication in applied and science college of Hashemi Nejad in Khorasan Razevi in growing season 2013-2014 was carried out. The first and second factor were four concentrations of ferrous and zinc sulphate (zero, 70, 140 and 200mg.l-1). Experimental treatments were applied in three growth stages (50 percent of vegetation, flowering and seed filling stages). Results were showed that the highest plant and number of lateral branches was obtained in non supply ferrous sulfate and 70mg.l-1 zinc sulfate. The maximum dry weight of root and weight of the seed per plant were produced in consuming 70mg.l-1 zinc sulfate with 70mg.l-1 ferrous sulfate. The seed weight had significant and positive correlation with fresh (r=0.72**) and dry weight of biomass (r=0.70**) and also with the number of seed per plant (r=0.90**). Generally, there was more obvious response in cumin plant growth to applied zinc sulphat than applied ferrous sulphate micronutrients.
