Milkweed allelopathy in the agroecosystem
Laboratory experiments were conducted to evaluate the allelopathic effects of different concentration (5, 10, 20, 30, 40, 50%) of Calotropis procera(Aiton) W.T. leaf aqueous extractusing different indices for germination, seedling and physical growth of wheat (Triticum aestivum) and black mustard (Brassica nigra). Except for germination speed, results indicated that the extracts have such allelopathic potential which can significantly reduce the ... Read more
