Nanoparticles as Potential Improvement for Conventional Fertilisation in the Cultivation of <i>Raphanus sativus</i> var. <i>sativus</i>

The use of nanoparticles in fertilisation has confirmed positive effects on plant growth and yield. Simultaneously, there is still little research into the effects of nanoparticles on the antioxidant system of plants. Due to the positive effect of nano zinc oxide on plants and the special property o...
