The Effect of Sorghum Bicolor Extracts and Lower Rate of Trifluralin Herbicide on Weeds in Vigna Sinensis L.

Abstract

Abstract Allelopathic influence of Sorghum bicolor cultivar (Cv Enqatht) on the growth and development of a few weeds test (Beta vulgaris L., Chenopodium album L., Amaranthus retroflexus L., and Malva rotundifoloia L.) and weeds company with Vigna Sinensis L. crop were investigated. All treatments significantly (0.05) reduced total weed density by (32.4) and total dry biomes by 57.1)n gm above control at a rate of 4 gm kg-1 soil results pots experiment. However, when the 8gm.kg-1 of soil was put to pots altered with Sorghum bicolor residual residue, the decrease was much greater. The second experiment was done using a R.C.B.D design to investigate the effects of Sorghum bicolor decarase (rate 800 g. meter-2) on the development of Vigna Sinensis L. crop and companion weeds, compared to a control treatment and a full rate of Trifluraln herbicide (50 percent) (2.4 L.h-1). The field experiment result showed a trend of Sorghum bicolor residue at 800 gm/kgm effect on number of company weed of Vigna Sinensis L., crops by (38, 4.7, 24, 10.67, 38.7) and biomass (68, 63.7, 61.7, 22.33, 27.3) gm compared to control treatment, however, this reduction was further increased when the 50 percent full rate of herbicide was applied to plots amended with Sorghum bicolor residues. In comparison to the control treatment, the application of Sorghum bicolor residues in conjunction with a 50 percent rate of trifluralin boosted biological yield and harvest index of Vigna Sinensis L. crops. Conclusion: Sorghum bicolor residue might be employed as a realistic and ecologically sound weed management and soil enhancement strategy for Vigna Sinensis growing crops.
