relationships between yield and potato affected by different levels of bio-fertilizer "al-ziest" chemical oral- even

in order to evaluate yield and yield components of potato, affected by different levels of bio-fertilizer "al-ziest" and chemical fertilizers oral-even factorial experiment in a randomized complete block design with two factors , the first factor of four level of bio-fertilizer "al-ziest" (a1 = control, a2 = 100 ml, a3 = 150 ml, a4 = 200 ml), and the second factor in four levels of chemical fertilizer oral-even (b1 = control, b2 = 60 g; b3 = 80 g, b4 = 100 g) with three replications for foliar in  ardy village located in the city of ardabil in 1393 was carried out. the results showed a correlation between: the number of main stems per plant and the number of tubers per plant, tuber weight per plant, total tuber yield and salable tuber yield and number of tubers per plant and the number of main stems per plant, tuber weight per plant and total and salable tuber yield was significant at probability level. weight of tubers per plant and the number of main stems per plant, number of tubers per plant, tuber weight and total tuber yield and marketable had a significant positive relationship. as average tumor weight by weight of tubers per plant, total tuber yield and salable tuber yield significant at 1%. total tuber yield and salable tuber yield with number of main stems per plant, number of tubers per plant, tuber weight per plant, tuber weight and a significant positive correlation indicates that the probability of a percent.
