The Study on Agroclimatic Conditions of Sunflower in Kurdistan Province by Means of GIS System
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 4
Abstract
The present article is aimed at study on agroclimatic conditions of cultivation of sunflower throughout selected substations at Kurdistan Province by means of GIS system. In this investigation, meteorological data have been received from synoptic stations based on daily, monthly, and annually trend from Iran Meteorological Organization (IMO) at Kurdistan Province and then homogeneity of data has been explored by (Wald- Wolfowitz) Run Test. Methodology of the research is of statistical descriptive type. Data analysis was carried out by means of Growing Degree Day (GDD) technique and method of Deviation from Optimum Percentage (DOP) plus phenology index as well as thermal potential within environment of statistical software (EXCEL and SPSS). Under agroclimatic conditions, the results of this survey may indicate that the time period among July and September is considered as active months in terms of agriculture based on thermal potential in this region. The In mid-May are the best calendar for cultivation of sunflower month in all the aforesaid substations. Time of harvesting sunflower crop is end August for Bijar, Saghez, and Sanandaj stations while this time is Mid-August for Marivan station. With respect to the phenological method, dates of cultivation until budding, flowering, and the end of flowering stage and maturation start respectively sooner in Marivan station than other stations in this region.
