Abstract
Studying of climatic elements are one of the most important factors influencing on agricultural crops production and developing of agriculture activities in every region that led to increasing production . by studying of agro climatology can be determined potential facilities in different areas and used optimum of facilities . this research was established by determining temperature potential of ecological capacity of canola cultivation areas in Golestan province . climatic grouping by Dumartin method, was established to general determine of region climate by using of suitable cultivation temperature( 15-20°c) and Vibul method ( 75% probability )is determined cultivation date . based on measuring of effective required day degree in every steps , is measured given date to phenology step .suitable and limited temperatures different steps of canola phenology is derived from different sources and measured its occurrence probability in studied region . medium relation ship of canola performance and suitable and limited temperatures was studied in different steps of phenology . after organizing and forming of temperature layers using of regression equations , the cultivation regions are divided in to four areas , very desirable , desirable , rather desirable and undesirable .
