Title
Effect of different sowing dates with constant density on the performance of the developed three varieties of sunflower
Authors
Abstract
To study the performance of three Iranian genotypes of sunflower: (1) Farokh, (2) Qasem, and (3) SHF81-90 by conducting a field experiment with a randomized complete block experimental design combined analysis with the constant density of 66600 plants per hectare. We repeated the experiment three times in order to get accurate results. The experiment was conducted in Research Station of Islamic Azad University of gorgan from Feb 15th and March 15th and April 15th. Our results shows that the genotypes of Qasem attains the highest yield of sunflower in the first planting date; Qasem produces a higher grain number per head and heavier grain weight. Based on our results we recommend planting on the first date in order to obtain the best yield. We additionally observed that the performance of seeds has positive correlation with the number of seeds in the plate and the average weight of a seed while there exists a negative correlation
between the performance of seeds and the rate of empty seeds.
between the performance of seeds and the rate of empty seeds.
