Evaluation of Management Strategies in Potato Weed Control with Emphasis on Integrated Weed Management

In order to investigate the effects of different management methods on weed density and biomass and potato yield loss, an experiment was conducted at Research Farm, Faculty of Agriculture, Ferdowsi University of Mashhad at 2004. The experimental design was a randomized complete block with a strip split-plot arrangement and three replications. Factors included, two tillage systems (conservation and conventional) and eight weed management practices (herbicide, hand hoeing, cultivator, herbicide plus hand hoeing, herbicide plus cultivator, hand hoeing plus cultivator, reduced herbicide use plus hand hoeing, reduced herbicide use plus cultivator). Results showed that LAI and above ground biomass of potato was greater in integrated treatments until canopy closure
