Abstract

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 (400 plants and 200 plants/m²) and beans (40 and 20 plants/m²) 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 (400 wheat plants and 40 bean plants/m²), weed growth in pure crops and intercrops showed little difference. Even at densities of 200 wheat plants, 20 and one bean plant/m², the effects of multiple crops on weed control were more effective than in monocultures. For example, the minimum number of weeds was 16 in the mixture of 1 row of beans and 4 rows of wheat and 24 in the wheat-only crop at a density of 400 plants/m². 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.

Graphical Abstract

Highlights

Weeds are one of the factors limiting the growth and development of wheat planting in the country and the region.
Multi-cropping can be considered as one of the effective methods in controlling weeds and increasing field efficiency.
In this study, two plants, wheat and bean, were selected according to their characteristics to create a multi-cropping system in the region.
