Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 8

Abstract

In order to study about the diversity of species, functional and structure of weeds community on soybean farms in two different areas; fields and mountains of both zones in Neka and Galugah, located on east part of Mazandaran State, 410, number of samplings from 2820 hectares was chosen from Agriculture farms on early stage of growth nodes on fourth step about Soybean have been studied. Sampling was done randomly, by systematic method according to W pattern by 0.5×0.5 quadratic square meter and density, percentage of abundance, and weeds uniformity were determined by separating genus and species. In this research 47 species of weeds from 23 families of plants were identified. Asteraceae and Poaceae families, each one with eight genuses had the highest kind of dicotyledonous and monocotyledonous. Also annual weeds with 33 species and perennial with 13 different species had sequent the highest and lowest number of a species to themselves. At the soybean’s farm which is located on mountain areas, the lack of herbicide application, frequency of weeds by wide leaves was higher. Also in this area the relative of abundance on C3 to C4 species with comparing to field areas, had the higher among themselves, because the lack of average temperature. The highest Shannon and Simpson indices, on mountain areas were seen respectively equal to 1.13 and 0.14 and lowest of these indices on field areas were sequence equal to 1.04 and 0.09. The differences between managements approaches towards these two areas were studied an agronomy filters over the population and combined different weed species were effective.
