Abstract

In order to study the Competitiveness of potato cultivars with weeds, an experiment was conducted in 2016 at field research of Ardabil Agriculture and Natural Resources Research Station. For this purpose a randomized complete block has been used with three replications. The treatments include ten potato cultivars, grown with and without natural weed competition, with yield loss ranging from 3% in Satina to 84% in Agria in weedy condition. Also, the Competitive Ability (CA) of the cultivars differs. It is observed that satina cultivar has had the highest competitive index (CI) and could reduce the weed dry mass by two folds in comparison to Spirit as a poor cultivar. Also, stem diameter is seen to be negatively correlated with weed dry mass and positively correlated with tolerance and competition indices. Stem diameter in Satina has significantly stodd higher than Spirit cultivar. In general, the results of this study declare that Satina cultivar is considered as a tolerant and recommendable option for cultivation in Ardebil region than other cultivars, less susceptibility index (SSI) and more stable than weed, and can be introduced as a competitive cultivar in non-chemical weed management programs.
