Abstract

Weeds identification and distribution is one of the most important basics in their management, so the weeds of chickpea fields in rain-fed areas of Maragheh, North west Iran, were systematically sampled and the traits of species distribution, life cycle, canopy, species DIVERSITY and similarity indices were studied. Convolvulus arvensis, Cardaria draba, Sophora alopecuroides, Acroptilon repens, Tragopogon graminifolius, Euphorbia helioscopia, Geranium tuberosum and Falcaria vulgaris showed high frequencies among weeds. Also DIVERSITY, UNIFORMITY and dominance of weed population were evaluated via Shannon-Wiener index and similarities and differences between various regions based on species DIVERSITY were evaluated by using Sorensen and Jaccard indices. Among the studied areas, the highest and lowest RICHNESS index was belonged to Khodajo (44 species) and Khorma Zard (28 species), respectively, whereas, the regions had equal Shanon-Winener DIVERSITY index. Tragopogon graminifolius, Convolvulus arvensis and Galium tricornutum with relative dominance indices of 38.82, 32.92 and 28.39 respectively, were detected as dominant weeds in Maragheh chickpea fields.
