Abstract: 

Spatial diffusion indicates the ways and the means of diffusion of one phenomenon from its origin to the societies who are ready to accept that phenomenon. However, the process of diffusion may start immediately after emergence of phenomenon or take place during several centuries. At global level spread of civilization, technology, nuirition quality, trend of urbanization and change in the quality of housing and settlements has been a process that took many centuries or even millenniums. But the phenomenon such as spread of diseases, poverty, and urbanization and so on are cases which show rapid spread.

In this research work an attempt is made to explain the spread of saffron farming from the southern Khorasan in Iran to the areas located in central and the northern Khorasan. In fact the theoretical base for this research work was first put forward in 1953 and later on became well developed theory with publication of a book entitled "Spatial diffusion and innovation process" in 1968 by Toresten Hagerstrand. This theory has not been tested in Iran especially in case of agriculture sector to date. This research work is first attempt to justify the spread of saffron farming from the southern Khorasan to the other parts of Khorasan. The study results show that the spread of saffron farming is totally in tone with the theoretical basis provided by Torsten Hagerstrand. However, the diffusion of saffron farming did not follow the exact patterns of theory. The major findings of the research project are: Nature of Diffusion: diffusion of saffron as a phenomenon followed pattern of regio nal diffusion as a result of which saffron farming were spread from southern areas of Khorasan to the rest of Greate Khorasan. Also the intensity of saffron farming in new region (Torbat Heidarieh in the northern Khorasan) is higher than its origin (Ghaenat in the southern Khorasan), however that part of theory which explains the transfer of location of spread from its origin to new areas resulting in draining the original base from the phenomenon is not true in case of saffron.

Process of wave in Diffusion's profile: Stages one to three in theory are applicable in case of saffron farming diffusion. However, the fourth stage of theory which explains the maturity and stop of diffusion phenomenon was not applicable to the case of saffron farming.
