Abstract

Weed spread and diversity were studied both chemical and non-chemical treated fields of cotton (Gossipium hirsutum L.) in Esfarayen. In this study FREQUENCY, UNIFORMITY, density and EVENNESS parameters in three sampling dates (30 days after sowing, flowering and harvesting stages of cotton) were determined and analyzed by "CLUSTER ANALYSIS". The results showed that from 29 weed species belonged to 5 plant families in cotton fields, poaceae family with 6 species was the most frequent family. Application of herbicide had significant effects on FREQUENCY, UNIFORMITY, density and EVENNESS parameters in the first sampling date. DOMINANCE distribution, species richness and UNIFORMITY in herbicide treated fields were lower than non-herbicide plots. Species richness in non-herbicide was higher than herbicide treated plots and it was similar for three sampling dates. At first sampling date, species diversity in sprayed and non-sprayed fields was significantly different, and herbicide application decreased species diversity. DOMINANCE index in fields with herbicide was higher than fields without herbicide.
