  Using growing degree days (GDD) for expression of duration of plants’ developmental stages is preferred over calendar time. Therefore, determination of GDD and zoning of regions is very important for on time and correct agronomic practices and also for better land use. To determine the required GDD for developmental stages of spring safflower cultivars, the data obtained from planting-date ex...
