In this paper, two field experiments are implemented in two successive seasons of 2017 and 2018 in order to explore the effect of foliar application of IAA (indole-3-acetic acid) and weed control on potato traits. To do so, the related factors include two potato cultivars (Sante and Milva), foliar application of IAA in the rates of 0, 200, and 400 ppm, PRE application of metribuzin at 750 g ha-1, split application of metribuzin at 500 g ha-1 PRE, 250 g ha-1 POST application, hand weeding, and untreated control. This paper indicates that increasing IAA from 0 up to 400 ppm significantly increased potato tuber dry and fresh weight, tuber diameter, yield, shoot biomass, and HI as well as nitrogen, potassium, and phosphorus uptake. The application of IAA at 400 ppm significantly increased biomass of weeds at harvesting time. Weed control increased potato studied traits and the highest of them was recorded in split application of metribuzin with an increased ratio of 15% to 39% compared to the untreated control. A weed control reduced weed density and biomass by more than 50%. It could be concluded that using IAA at 400 ppm resulted in the enhancement of growth and productivity of potato when integrated with the split application of metribuzin. [ABSTRACT FROM AUTHOR] |
