Abstract

In order to investigate the soybean competitive ability (DPX cultivar) under interference condition different densities of Asian spider flower (0, 3, 5, 10, 15, 20, 30, 45 plant/m-2 ); an experiment was conducted based on randomized complete blocks design with three replications in 2015– 2016 growing season in Kalaleh, Golestan province. Different densities of Asian spider flower had a significant effect on biological yield, economic yield, 100 grain weight and pods per plant of soybean. The highest grain and biological yields of soybean were 374. 9 and 734. 30 g/m 2, respectively which observed in weed-free treatment. However, these traits declined nonlinearly as weed density increased, so that in 45 plant/m-2 interference treatment, economic and biological yields reached 172 and 344. 38 g/m 2, respectively.
