Â Abstract Â The plain of Lower Jarghouyeh which is located in the southern part of the province of Isfahan is a suitable environment for the cultivation of the plant of pistachio. In this research has been used of attributive, compound and comparative and a pilot area was established in Lower Jarghouyeh and monitoring of phonological and aero logical conditions of the growth of pistachio were carried out for a year in 1383-1384. The recorded data combined with the secondary data were analyzed through the application of SPSS and EXCEL software. Â The analysis has concluded that the biological activity of pistachio lasts 273 days in which the planet needs 4234. 6 degree-days for different stage of growth. While rainfall and radiation are the limiting factors, relative humidity and soil conditions of Lower Jarghouyeh havenât demonstrated any limitation for pistachio growth, but a cold spring and early low temperature in autumn are the hindering environmental factors that even stop the germination process. Â Although temperature is start and motor of wakefulness of growth in period of biological active in each plant, but it can stop or it can dispatch the plant. Knowledge suitable and necessary temperature and so degree of extent in each phonological period by total earned temperature and so minimum and maximum temperature of tolerance of plant and so relative moisture and necessary water and soil are problems that those should pay attention for cultivation each plant. Â More over climatic knowledge in each region is a subject that it should pay attention for cultivation of each plant in all region and so, probability of faced of different stage of growth of plant with suitable and unsuitable happenings should be certain. In this research it was done for cultivation of pistachio.
