Nanotechnology has become a solution to most of the problems facing humans nowadays. In agriculture, nanofertilizers play a pioneer role to enrich crop productivity and minimize environmental pollution problems. In this paper we investigate the possible effects of using two engineered nanomaterials nanochitosan (Cs) or carbon nanotubes (CNTs) either alone or loaded with NPK as fertilizers on French bean plants. The new approach used was to compare between two different methods of application: seed priming and foliar application. From the obtained results, it is apparent that foliar application is better than seed priming. This is evident from the improvement of growth, yield, and antioxidant system of plants and biochemical content of yielded seeds of foliar application than in seed priming as compared with control. In addition, foliar treatment shortened the days to harvest without reducing yield by 37.5% (80 days) as compared with control and seed priming treatment (110 days). Of interest, Cs nanoparticles appeared to improve growth and yield parameters more than CNTs in foliar application treatment. In conclusion, foliar application of nanofertilizers holds tremendous potential to improve crop productivity and we recommend the use of nanofertilizers as foliar application.
