Abstract

Because of prevalence and importance of redroot pigweed (Amaranthus retroflexus) in most fields, a factorial experiment in three replicates was conducted in greenhouse conditions. The examined factors were extracting of different parts of sunflower (leaf, stem, root and whole plant), different extract concentration in 5 levels (extract as 1:20, 1:15, 1:10, 1:5 and control) from different growth stages as vegetative, inflorescence and seed filling. Results showed that leaf extract in inflorescence stage had the most reduction effect on radicle and plumule length, germination percent and germination time spread. Greenhouse results indicate that the effect of extract of different parts of sunflower decreased significantly plant height, root length and dry weight, leaf area, shoot dry weight, 1000 kernel weight and seed production of redroot pigweed. Leaf extract in vegetative stage of sunflower had the most reduction effect. Decreasing germination percent was 87% and seed production was to 74% by sunflower extract. Therefore, the sunflower allelopathic potential can reduce pigweed in the field.
