Abstract

   Soybean, Glycine max (L.) Merr., is one of the most important oil crops of the world which also has tremendous importance as a food legume. In the past decade, interest in the soybean crop in Sudan has increased due to increased demand for the crop as an important crop in the food industry. Weeds are considered one of the major limiting factors in soybean production. The aim of the present study was to evaluate the efficacy and selectivity of the herbicide oxyfluorfen on weed control in soybean at Gezira State, Sudan. A field experiment was carried out at Gezira Research Station Farm, Wad Medani, and Sudan during summer season 2018/19. The oxyfluorfen (Harris 240 EC®) was applied at three doses as pre-emergence treatment. The rates were 0.2678, 0.3371 and 0.446 Kg a.i./ha. Weeded and un-weeded treatments were included for comparison. The treatments were arranged in a randomized complete block design with four replicates. Data were subjected to descriptive analysis and analysis of variance procedure (P ≤ 0.05). Significant means were separated using Duncan’s Multiple Range test. The results showed that all herbicide treatments were effective in weeds control. They significantly reduced weeds infestation compared to un-weeded control and significantly promoted the yield and various growth characters of soybean over un-weeded control treatment. Application of oxyfluorfen at the rate 0.3371 and 0.446 Kg a.i./ha significantly controlled grasses and broad leaf weeds in soybean. It also found superior in respect of various growth and yield attributes. Oxyfluorfen at the rates 0.3371 and 0.446 Kg a.i./ha gave comparable seed yield (979.1 and 1079.2 kg /ha, respectively). Chemical analysis of soybean seeds showed that no residues of the tested herbicide were detected. It concluded that the tested pre-emergence herbicide Oxyfluorfen 240 Ec at the rate 0.3371 kg a.i./ha could be used effectively and safely in controlling weeds in soybean crop.
