Abstract：A plot experiment was conducted to study the effects of dye by-products ( BP) as fertilizer on rape growth.Under the condition of equal nitrogen amount, the application of BP had similar effects on bio-mass, leaf area, plant height, root length and chlorophyll content of rape compared with ammonium sulfate, and all were higher compared with no fertilization.The application of ammonium sulfate and BP increased the rape yield by 3.25 and 2.73 times as basic fertilizer, while 97.1%and 76.5%as foliar fertilizer, respective-ly.The application of BP also could improve the contents of organic matter and other nutrients in soil.
