This plan was performed to study the influence of Fe, K, N, and P elements on phytomass amount and Pelargonium graveolens essence percentage amount and fragrant geranium essence in dry and desert region research station of Kashan iron fertilizer and nitrate, phosphate, potassium fertilizers were used in main and secondary plots, respectively. Analysis of data resulted from the performance of aerial organ wet products showed that the difference between various fertilizer treatments (nitrate, phosphate and potassium) and between the mutual effect of the main (Fe) and secondary (N.P.K) treatments were significant in 1% and 5%, respectively. So that the highest performance of aerial organ wet products was 73.34 ton/hectare in a 200 kg N/hectare treatment. Also, the maximum wet aerial organ was obtained in 200 kg N and Fe (1 per 1000) with an average of 77.67 ton/hectare. Analysis of data from the essence performance also showed that maximum essence obtained in 200 kg N/hectare treatment with an average of 115.79 kg/hectare. In addition, analysis of data from dried anthophorous lop product showed that the difference between elements (N, K, P) was significant in a 1% level and the maximum performance obtained by using 200 kg N/hectare on 17.6 ton/hectare of dried anthophorous lop product which has no significant difference to the application of Pelargonium graveolens wet crop in industry, using at least 100 kg N/hectare and Fe 0.5 per 1000, in from of solution dispersion can lead to the maximum crop production on Kashan.
