A pot culture study has been undertaken to evaluate the effect of rolling and pickling industrial sludge amendments on growth response and bioaccumulation of heavy metal in wheat seedlings. Processed acidic waste was first treated with three doses of lime (0, 0.5 and 1%) and then mixed with two soils in different ratios (0, 10 and 20%). Samples were filled in earthen pots (2Kg/pot) one week bef...

introduction: increasing crop competitive ability is an important part of integrated weed management (iwm). in this regard, identifying weeds reaction to soil fertility status for developing fertilizing methods, as components of iwm programs, is a necessity. materials and methods: in order to evaluate the growth characteristics of purple nutsedge under the conditions of interference with onion,...
