| Abstract | ||
| A pot experiment was conducted in which kidney bean seeds were planted in sandy soil either alone or amended with different concentrations of urea, peat moss and multi-walled carbon nanotubes. In general, soil conditioners amended to sandy soil induced significant increases in all growth and reproductive parameters of kidney bean throughout the four successive growth and developmental stages under study. In addition, soil conditioners induced pronounced significant increases in photosynthetic pigments at vegetative growth stage. Furthermore, the addition of CNTs alone or in combination with urea and/or peat moss to sandy soil induced significant increases in all enzymatic and non-enzymatic antioxidants determined in kidney bean plants. In conclusion, the disparity of changes in photosynthetic pigments, enzymatic and non-enzymatic antioxidants determined in kidney bean plants at vegetative stage, and the associated changes in all growth and developmental parameters, appeared to be a function of metabolic changes as influenced by different concentrations of CNTs and/or soil conditioners used. Furthermore, the present results give a clear indication that CNTs (foliar spray) + urea + peat moss was superior than CNTs (soil incorporation) + urea + peat moss, and could be recommended as the most effective soil conditioner for best reclaiming sandy soil. These new and novel results may also be a new nanotechnology strategy that can be further applicable for reclaiming sandy soil to be ready for cultivation of different crops. | ||
