In order to evaluate the application of auxin hormone and weed management on the performance of physiological and chemical characteristics of potato cultivars, a split factorial experiment in the form of a randomized complete block design with three replications in two crop years 2016-2016 and 2016-2016 in Bardsir city of Kerman province. Done. The treatments include two potato varieties, Milva and Sante, foliar spraying of auxin hormone at three levels, no hormone consumption, 200 and 400 ppm and weed control, pre-emergence application of metribuzin herbicide with an amount of 750 grams per hectare, two-stage application Metribiozin, one stage of 500 g/ha pre-emergence and the second stage of 250 g/ha 10 to 15 days after potato sprouting, weed control through manual weeding, control without weed control. The results showed that increasing the consumption of auxin hormone significantly increased the diameter, dry weight and tuber performance. Weed control was achieved during the two-step application of Bozin herbicide with an increase ratio of 15 to 39% compared to the control without control. The highest yield of tubers was obtained under the two-stage application of Bozin herbicide and the application of 400 ppm of auxin hormone at the rate of 38055.33 kg per hectare, and the number of tubers in potato was obtained under the two-stage application of Bozin herbicide. The use of different amounts of IAA in this experiment led to an increase in the content of nitrogen, potassium and phosphorus compared to not using it.
