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 .
