Title: Allelopathic Potential of Canola (Brassica napus L.) Residues on Weed Suppression and Yield Response of Maize (Zea mays L.)
Abstract: Decomposition of some crops residues release secondary metabolites that exhibit phytotoxic effects on other plants. In order to determine allelopathic potential of canola on maize grain yield and suppression of some common weeds, a field experiment was performed in 2010. Treatments were weeding in two levels (whole season weeding and whole season interference) and incorporation of canola residues into the soil, in three levels (0%, 15% and 30%). Allelopathic effects of canola reduced density, fresh weight and dry weight of weeds. In particular, Solanum nigrum L. and Amarantus retroflexus L. were inhibited while maize yield was not influenced by canola residues. Keywords—Allelopathy, Canola, Maize, Weed control.
