Abstract :
In order to evaluate the effect of different levels of potassium nanoparticle foliar application on some physiological traits of fennel (Foeniculum vulgare Miller) in Bam city, this research was carried out in the spring of 2019-1400 as a factorial experiment in the form of a randomized complete block design. Three repetitions were performed. In this experiment, different stages of foliar spraying as the first factor in the three stages of stem formation, flowering and fruiting; And different concentrations of foliar spraying of potassium nanoparticles as the second factor in five concentrations including no foliar spraying (control), 2, 3, 4 and 5 per thousand potassium nanoparticles. Based on the obtained results, it was observed that the highest seed carbohydrate (3.12 mg/g), seed nitrogen (2.48%) along with foliar spraying at a concentration of 3 per thousand potassium nanoparticles and the highest amount of seed phosphorus is equal to 1.65% and the highest amount of seed potassium is equal to 3.65% along with foliar spraying at a concentration of 4 per thousand potassium nanoparticles in the stem formation stage in the second year of the experiment. Also, the highest percentage of seed essential oil (4.37%) combined with foliar spraying at a concentration of 5 per thousand potassium nanoparticles, and the highest yield of seed essential oil (69.5 kg per hectare) combined with foliar spraying at a concentration of 4 per thousand potassium nanoparticles in The fruiting stage was obtained in the second year of the experiment.
