The Asian Development Bank (ADB) Present study made to assess the response of Cowpea (Vigna unguiculata (L.) Walp) under the influence of copper with special reference to seed germination and seedling growth. Copper was applied in the form of copper-chloride (CdCl2 5H2O). Various concentrations of copper (0, 5, 10, 25, 50, 100, 150 and 200 mgl-1) were prepared and treated with various Cowpea varieties viz., CO 2, CO 6, CO 7, Paiyur-1 and VBN-2 were used for germination studies. It is evident from the results obtained that the increase in copper concentration affected all the growth parameters such as seed germination percentage, seedling length and seedling fresh weight and dry weight.
