The Effect of Zinc Oxide Nanoparticles on Growth of Sweet Chilli

Abstract

In this research, the effects of zinc oxide nanoparticles (ZnO NPs) on the growth of the sweet chilli which sprayed with water containing different concentrations of zinc oxide nanoparticles, were studied by measuring the stem length, the root length and the moisture content. The results showed that the sweet chilli, which sprayed with water containing 20 mg of ZnO NPs, had the highest growth. The average of the stem length and the root length was 22.36 ± 070 and 18.20 ± 1.30 cm, respectively as well as moisture content found to be about 84.02 %. Whereas, the height and a number of the leaves of sweet pepper sprayed with water containing 10 mg of ZnO NPs and with pure water, were similar. They have an average length of the stem approximately 19.76 ± 2.03 and 19.8 ± 2.62 cm, respectively. However, the average length of the roots was rather different.
