Weeds pose the greatest threat to tomato production due to their apparent reduction in production capacity and quality and increased production inputs. Plant species are considered essential interactions with the agricultural ecosystem. This study aims to study the plant diversity associated with the tomato crop and the extent of the impact on this crop in different plant communities or regions, which are El-Gouba, El-Thahar Alhmar, Teeret and Omar Al-Mukhtar. Some indices were used as tools for weed management in tomato production. From each location, four fields of weeds randomly were selected and one meter length for every 10 meters from each line was collected to study the weeds diversity. Some indices were used: mean, standard deviation, covering density, relative covering density, frequency, relative frequency, Shannon index, Margalef index and Jacardo index. The results showed that no difference between regions in the average presence of species, the standard deviation between regions, relative density, species coverage of the soil surface, relative frequency of species, and Shannon’s index according to the study regions. Meanwhile significant effects with different locations in case of density of covering, species frequency, Margalef and Jacardo indices. In conclusion these tools are very beneficial in weed management and studying the species diversity.
