The evaluation of integrated weed management efficiency in Bardsir potato fields

In order to investigate the effects of different integrated weed management methods on potato, an experiment was conducted on research filed in Najaf Abad, Bardsir, in 2009. This examination was designed in a randomized complete block (RCB) design with 4 replications and 9 treatments including 1- Metribuzin Herbicide (H), 2- Hand Weeding (HW), 3- Cultivation (C), 4- Metribuzin Herbicide + Hand Weeding (H+HW), 5- Metribuzin Herbicide + Cultivation (H+C), 6- Hand Weeding + Cultivation (HW+C), 7- Reduced Herbicide+ Hand Weeding (RH+HW), 8- Reduced Herbicide+ Cultivation (RH+C), and 9- weed free. The results indicated that (H+HW) and (H+C) treatments showed the lowest weed biomass. The experiment treatments had a significant effect (p≤0/01) on potato tuber yield. Mean yield comparison showed that the highest potato tuber yield occurred in (H+C) and (RH+C) treatments; then in (H), (H+HW) and (RH+HW), respectively. ANOVA results showed that small, medium and large tuber numbers were significantly affected (p≤0/01) by the treatments.
