To study climatic elements and adaptability of agricultural crops in Kabootarabad agricultural research station of Esfahan, thermal and humidity variables were used (1986-2008). Normal distribution was used for estimation of occurrence probability of maximum and minimum critical temperatures and returning period. Daily mean temperature, day length, relative humidity, precipitation and sun shine hours were 15.2 °C, 12.43 hours, 39.5%, 115.8 mm and 3245.5 hours, respectively. Probability (%) of 0 °C and less from Oct. 21 to Nov. 30 and March. 6 to April. 6 varied from 1 to 99%. Probability (%) of 37 °C and more than that from May 23 to July 12 varied from 1% to 99%. January and July had the maximum and minimum relative humidity of 60.9% and 23.4%, respectively. Spring, summer, fall and winter mean precipitation were 30.3, 3.1, 24.2 and 58.2 mm, respectively. Therefore in this station there is low risk of minimum and maximum temperatures on growth and development of agricultural crops provied reliable water sources for irrigation requirements are available, and there is no limitation of day length and sunny hours for growth and development stages of most crops.
