Abstract:   (37270 Views)
A pot experiment was conducted in Isfahan University of Technology research greenhouse to investigate the effects of sewage sludge, compost and cow manure on growth and uptake of Fe, Zn, Mn and Ni in tagetes flower. A completely randomized research with three treatments (sewage sludge, compost and cow manure at 25 Mg ha-1) and three replicates was performed. Application of organic wastes significantly increased organic matter and CEC of the soil. Application of compost significantly increased DTPA-extractable Fe, Zn, Mn and Ni of the soil. The use of organic wastes increased tagetes flower growth. The growth of plant was highest in the compost treatment. Results indicated that Fe, Zn, Mn and Ni uptake by plant shoot, and the percentage of metals translocated to the shoot was greater in the compost treatment compared to other treatments. In general, the application of compost for tagetes flower had a positive impact on plant growth parameters and micronutrients uptake.
