Abstarct: In order to study the effect of foliar spraying of nettle and valerian leaf extract and calcium chloride on growth, function and physiological traits of black-eyed bean, a factorial experiment was conducted baxsed on randomized complete block design with three repetitions in 2020 at the research farm of Semnan County's Agricultural and Natural Resources Research Center. Treatments were foliar spraying of nettle leaf extract at three levels (0%, 10% and 20% volume), valerian root extract at three levels (0%, 10% and 20% volume) and calcium chloride at two levels (0 and 10 mmol); they were applied before flowering with two days interval. The results of this study showed that foliar application of valerian and nettle extracts, especially at a concentration of 20%, increased traits such as weight of dry leaves, stems, pods and grain yield. However, the combination of the highest concentration of valerian with 10% nettle also improved the properties of malondialdehyde, flavonoids and grain protein. Foliar spraying of valerian and calcium chloride increased lateral branching, dry matter, number of pods per plant, grain yield, leaf pigments, flavonoids, protein, protein yield and grain calcium. Foliar spraying of nettle extract and calcium chloride improved plant height, leaf area index, dry leaf and stem weight, number of pods per plant, number of seeds per pod, grain yield, leaf pigments, relative leaf water content, malondialdehyde, protein and grain calcium. Foliar application of all three experimental treatments including valerian and nettle extracts with calcium chloride, also improved almost all of the studied traits. Meanwhile, the combination of 20% valerian and nettle extracts with calcium chloride was more effective because it improved important traits such as grain yield, malondialdehyde content, protein content and grain calcium. In general, foliar application of medicinal extracts with calcium chloride had a positive effect on the traits studied in this research.
