Weed seed bank studies in the field of Fodder Cowpea [Vigna unguiculata (L.)]
Publication Date : 26/05/2015
This study evaluated the effect of herbicidal treatments on diversity of weed seed bank in fodder cowpea (Vigna unguiculata (L.) cropping field. Four weed species were common to all the experiments during the winter season. Weed diversity was greater in pendimethalin (1.34) at 0-15 cm depth and Quizalofop ethyl + oxyflorfen (1.09) at 15-30 cm depth. Considerably smaller size of soil seed bank was found in the 15-30 cm soil depth. About three-fourth of soil seed bank during winter season was accounted by Anagallis arvensis and Spergula arvensis in all the treatments. Build-up of very large seed bank of Anagallis arvensis and Spergula arvensis in all the treatments indicated that in future these species may become predominant weeds.
