Abstract:In order to investigate the effect of salinity stress, seed priming and foliar spraying with acetic acid and sodium hydroxide on the agronomic characteristics of cumin, an experiment was carried out in the research farm of the Jihad Agricultural Management of Dana town in the form of a split plot in the form of a randomized complete block design and in three replications. experimental treatments include irrigation at three levels (7 days, 10 days and 14 days) as the main factor and priming treatment at five levels (control, 0.5 mM acetic acid mal seed, foliar spraying of sodium hydroxide 2 per thousand, seeds of acetic acid + 0.5 mM acetic acid foliar spray) were as secondary factors. At the end of the growing season, the traits of total dry weight, number of seeds per pod, weight of 1000 seeds, biological yield, seed yield and harvest index were calculated. The results showed that salinity stress had a significant effect on all investigated traits. The highest average in the traits was obtained from the 7-day irrigation cycle. The effect of seed priming on all measured traits was significant. The highest average yield was obtained from the treatment of acetic acid + foliar application of acetic acid. Acetic acid was able to reduce the effect of salinity stress on plant growth under stress conditions.Abstract: In order to investigate the effect of salinity stress, seed priming and foliar spraying with acetic acid and sodium hydroxide on the agronomic characteristics of cumin, an experiment was carried out in the research farm of the Jihad Agricultural Management of Dana town in the form of a split plot in the form of a randomized complete block design and in three replications. experimental treatments include irrigation at three levels (7 days, 10 days and 14 days) as the main factor and priming treatment at five levels (control, 0.5 mM acetic acid mal seed, foliar spraying of sodium hydroxide 2 per thousand, seeds of acetic acid + 0.5 mM acetic acid foliar spray) were as secondary factors.
