“…The problem of the weed invasion in the agroecosystems is considered as one of the most persistent problems threatening the agricultural productivity (Ramirez et al, 2018). The weeds are known as pests as they interfere with plant growth and potentially compete with the crops for light, water and nutrients (Chaudhary and Akram, 1987;Qasem and Hill, 1995;Storkey, 2006;Gomaa, 2012;Wang et al, 2013;Onen et al, 2018;Salehian et al, 2018). The invasion mechanisms of these weeds are still not fully understood.…”

“…This is due to the complex interaction of weeds with the ecological and environmental settings in the agricultural ecosystem. However, many weed species exhibits remarkable adaptability to various environmental conditions (Onen et al, 2018;Salehian et al, 2018). Interestingly, there are evident reports that allochemicals secreted by the weeds eventually influence crop germination, growth and survival (Shah and Khan, 2006; Jabeen and Ahmed, 2009; Onen et al, 2018).…”

The weed diversity and distribution in agroecosystems can be controlled by environmental variables. In this study, soil physical and chemical variables were investigated in three citrus farms located in the northern part of Saudi Arabia. A total of 12 soil physical and chemical variables were measured. Among the studied variables, only organic matter (OM), pH, phosphorus (P), calcium (Ca), bicarbonate (HCO3) and sulphate (SO4) were significantly different (one-way ANOVA at P < 0.05) among the three studied citrus farms. The regression model (Adj-R 2 = 0.416, P=0.024) showed that the organic matter (OM), calcium (Ca) and carbonate (CO3) significantly affect the species richness of weeds. The multivariate model of CCA explained 68.64% of the variation of the taxonomic composition of weeds in citrus farms. It also revealed strong effect of soil texture (sand %), carbonate (CO3), pH and sulphate (SO4) on weed diversity and distribution. It was concluded that the soil physical and chemical properties are strong explanatory variables of the distribution of weeds in agroecosystems.
