Abstract
The present work aims at depicting the weed communities associated with the common crops and orchards in the cultivated land habitat in El-Behira Governorate and to relate them to some important soil variables. Seventy stands were selected to represent the major crops and orchards during summer and winter seasons in both of old cultivated land and newly reclaimed land in the study area. The results indicated that, the total number of weeds recorded in the cultivated land habitat is 109 species. Four vegetation groups were obtained after application of TWINSPAN classification based on the importance values of 109 plant species recorded in 70 sampled stands. The ordination of the sampled stands in the cultivated land habitat was applied using Detrended Correspondence Analysis (DCA). The vegetation groups obtained by TWINSPAN classification are markedly distinguishable and having a clear pattern of segregation on the ordination planes. The correlation between the edaphic factors and ordination axes led to the definition of the most effective soil gradients which correlate with the distribution and abundance of the identified vegetation groups in the cultivated land habitat.
