Investigation of bio-fertilizer and selective herbicides application on control of Chenopodium album and Amaranthus retroflexus in soybean
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 6
Abstract
This experiment was conducted during 2009 growing season as split plot with randomized complete block design arrangement in a field of Faculty of Agriculture, Islamic Azad University, Karaj branch, Iran. Application and non-application of bio-feltilizer (Bradyrhizobium japonicum) was the main treatments. The sub-treatments were application of herbicides consisted of trifluralin, ethalfluralin, metribuzine, oxyflorfen, bentazon, aciflourfen+bentazon respectively at 1.2, 1.16, 0.35, 0.48, 1.2, 1.06 Kg ha-1 and weedy check to control of redroot pigweed (Amaranthus retroflexus) and lamb's quarters (Chenopodium album). In this research, application of bio-fertilizer on efficiency of some herbicides was effective in decreasing weeds dry weight. The biomass of redroot pigweed (Amaranthus retroflexus) in treatment oxyflorfen was significantly less than weedy check and other sub-treatment. However, the herbicides compared with weedy check, had significant effect on the number of redroot pigweed plants. The biomass of lamb's quarters (Chenopodium album) in treatments metribuzine, ethalfluralin was significantly less than weedy check and other sub-treatment. Application of metribuzine compared with weedy check and other sub-treatment, significantly reduced the density of lamb's quarters (Chenopodium album). Application of aciflourfen+bentazon, bentazon compared with weedy check, resulted in significant grain weight of soybean.
