Abstract
A field experiment was conducted during the spring season 2011 at two locations,
the first location was kanipanka, in a research center, which belongs to the Ministry of
Agriculture and located about 36Km south-east of Sulaimani city, and the second was
conducted at the Qlyasan research center belong to the faculty of Agricultural sciences /
university of sulaimani. the aim of the study was to show the effect of different plant date on
growth characteristics. Yield, and yield components of Sunflower (Flamme variety). The
seeds were planted on 3rd March, 18th March, and 2nd April at Kanipanka, while the dates
were 14th March,19th March, and 3rd April at Qlyasan location, the completely
Randomized Design (CRBD) was done within three replications in both locations. The
results must be shown the existence of significant differences of the effect location of most
traits growth characteristics , yield and its components, where the superiority location
(kanipanka) in each of the characteristic of stem length, disk diameter, number of seeds /
plant, seed weight / plant, seed weight, dry matter yields, seed yields, oil yields and bio-
yields location (Qlyasan). However were not significantly affected by different planting date
on traits root depth, number of disks / plant and number of leaves / plant.
Keywords: Sunflower, Planting date, Growth characters, Yield component
