Nowadays, plant growth promotion and crop yield enhancement are assured by chemical fertilization and intensive agricultural management. Even if these practices provide adequate production yields, they lead to major environmental problems. Given the growing world population and increasing environmental awareness, sustainable and effective agricultural practices are required. Among the innovations developed in recent years, NPs are of great interest. Their use, already developed in various sectors (e.g., pharmaceuticals), is also advancing in agriculture. These nanotechnologies have numerous advantages. Moreover, they have numerous production and application advantages if their biosynthesis takes place using microorganisms. This chapter summarizes the most relevant literature on NPs produced by microorganisms, providing insight into their use in agriculture as plant growth promoters and crop yield enhancers.

Abstract
Nowadays, plant growth promotion and crop yield enhancement are assured by chemical fertilization and intensive agricultural management. Even if these practices provide adequate production yields, they lead to major environmental problems. Given the growing world population and increasing environmental awareness, sustainable and effective agricultural practices are required. Among the innovations developed in recent years, NPs are of great interest. Their use, already developed in various sectors (e.g., pharmaceuticals), is also advancing in agriculture. These nanotechnologies have numerous advantages. Moreover, they have numerous production and application advantages if their biosynthesis takes place using microorganisms. This chapter summarizes the most relevant literature on NPs produced by microorganisms, providing insight into their use in agriculture as plant growth promoters and crop yield enhancers. The literature study underlined that several microorganisms produce different types of NPs. Bacillus and Streptomyces are the most used bacteria for NPs biosynthesis. The use of fungi is also widespread, including mainly Fusarium, Trichoderma, and Aspergillus.Pubblicazioni consigliate
