چکیده مقاله:
To study the effects of row cropping of wheat and beans on weed control in Ahvaz climate, the experiment was conducted in the research farm of Khuzestan Faculty of Agriculture and Natural Resources as a randomized complete block experiment with four replications. The treatments studied included two types of plants, wheat (Chamran cultivar) and beans (local) as monoculture and in mixed composition in different densities of wheat (۴۰۰ plants and ۲۰۰ plants/m۲) and beans (۴۰ and ۲۰ plants/m۲) were planted. The results showed that the different plant densities of beans and wheat in multiple crops had a significant effect on the number and dry weight of weeds. Comparison of mean values showed that at suitable plant densities (۴۰۰ wheat plants and ۴۰ bean plants/m۲), weed growth in pure crops and intercrops showed little difference. Even at densities of ۲۰۰ wheat plants, ۲۰ and one bean plant/m۲, the effects of multiple crops on weed control were more effective than in monocultures. For example, the minimum number of weeds was ۱۶ in the mixture of ۱ row of beans and ۴ rows of wheat and ۲۴ in the wheat-only crop at a density of ۴۰۰ plants/m۲. It appears that plant density in this experiment was able to influence the number and dry weight of weeds through competition and more appropriate use of space.
