This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran,
Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on
Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on
2013. Treatments were four sowing dates such as May 5, Jun 5, Jul 11 and Agu 6. After seed maturity and
harvesting, a seedling growth tests were done for each sowing date treatment in four replications. It used 25
number seeds in each replication. Seedling growth test was performed by BP (between paper) method for 7 days
at 25C in incubator. The results showed that effect of sowing date treatment was significant on normal seedling
percentage, abnormal seedling percentage, non-geminated seeds percentage and radicle and hypocotyl length.
Mean comparison results showed that maximum normal seedling was recorded in Jun 5, Jul 11 and Agu 6 sowing
dates. Minimum non-germinated seeds were recorded in Jul 11 sowing date. Also, seeds of Jul 11 sowing date
treatment had the highest hypocotyl and radicle length. With regard to these founding and positive correlation
between radicle length and normal seedling percentage and hypocotyl and radicle length with abnormal seedling
percentage Jul 11 sowing date is the best sowing date for Azivash (Wild okra) cultivation in Gorganregional at
Golestan province because of production of highest normal seedling production, lowest non-germinated seeds and
longer hypocotyl and radicle length that result to highest seed quality and vigor.
