Abstarct: Most of the essential processes as photosynthsis, biosynthesis of organic materials, enzymes formation, cell division and water and nutrients absorption are dependent on vitamins B complex. These vitamins are considered as an antioxsidants against oxsidative stresses. Nowadays some studies have performed about foliar application of micronutrients specially zinc and vitamin B complex in order to decrease undesivable enviromental effects on plants and improve their growth. Hope that these ways be effective in increasing the product growth. For this purpose, an experiment has been designed to study effect of pyridoxine, pantothenic acid and zinc foliar application on quantitative and qualitative traits of green beans in research field of Shahrood University of Technology in 1395. Research treatments included foliar application pyridoxine in 3 levels (zero, 50 ppm and 100 ppm), pantothenic acid in 3 levels (zero, 50 and 100 ppm) and zinc in 2 concentrations (zero and 6 g/lit) as a factorial baxsed on randomized complete block with 3 replications. Foliar application was performed before flowering. The results represent foliar application of 100 ppm pyridoxine inducted significant increase in number of seeds per pod, seed yield, rwc, leaf soluble suger and protein yield compare to other treatments. Pantothenic acid of 50 ppm led to increase dry weight of pod, number of seeds per pod, green yield, seed yield, leaf pigments, flavonoids and protein yield. As well as zinc caused to increase some of the physiological traits as chlorophyll a, total chlorophyll and flavonoids. Interaction between pyridoxine of 50 ppm and pantothenic acid of 50 ppm caused to improve stem length, chlorophyll b, green yield and seed yield. Interaction between pyridoxine of 100 ppm and zinc led to increase number of seeds per pod, seed yield, flavonoids and protein yield. As well as interaction between pantothenic acid of 50 ppm and zinc led to improve stem diameter, green yield, seed yield, leaf pigments, rwc and protein yield. Generally, in performed experiment, pyridoxine of 100 ppm and pantothenic acid of 50 ppm were more effective on studied traits and foliar application of pyridoxine, pantothenic acid and zinc led to improve the most of agricultural, physiological and qualitative traits of green bean.
