abstract
An experiment was conducted to find out “Weed flora influenced by weed control in Summer Greengram (Vigna radiata L.). The soil of experimental field was loamy sand in texture with low in organic carbon and available nitrogen, medium in available phosphorus and potassium and having pH value of 7.45. The predominant weed flora observed in experimental field were Cynodon dactylon L., Digitaria sanguinalis L. amongst monocot; dicot weeds like Amaranthus viridis L., Alternanthera pungens., Convolvulus arvensis L., Vernonia cinerea L., Eclipta alba (L.) Hassk, Trianthema portulacastrum., Euphorbia hirta L., Physalis minima L. and sedges like Cyperus rotundus L. Weed free treatment itself indicate the total eradication of the weeds during entire crop growth period hence it may kept as best and superior one. For any weed parameter comparison it may be superior and excluded in the comparison with other weed control treatments. The weed populations of monocot, dicot and sedge at 30, 60 DAS and at harvest were found minimum under the application of ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS. Besides weed free situation, significantly lower dry weight of weeds were recorded under ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS. Among the different weed management treatments, the highest WCE and minimum weed index was observed under the weed free treatment followed by treatment ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS.
