Abstract The development of a seed coating with micronutrient release system is of extreme research importance for sustainable agriculture. In this work, a zinc release system was developed, using zinc-loaded PVA/Zein nanofbers. Solution blow spinning was used to produce nanofbers (average diameter of approximately 160 nm), as demonstrated by feld-emission scanning electron microscopy (FE-SEM), with some bead presence, which served as main zinc reservoir, as evidenced by energydispersive X-ray spectroscopy (EDX). Biodegradation assay showed the biodegradability of the PVA/Zein nanofbers with over 30% mass loss after 31 days, an important and desired ability for the proposed application. Encapsulation efciency of the nanofbers was measured at more than 90%. The release profle of zinc-loaded nanofbers was observed to be a two-step release, with an initial burst release (approximately 52% in 3 h) followed by a slow release (approximately 6% in 189 h), which is related to the zinc reservoir in the nanofbers that was observed by EDX and is a profle that is advantageous for the proposed application. Germination assay shows that the seed coating applied to the soybean seeds was efective, with the zinc released from the nanofbers being absorbed by the seeds and, acting as fertilizer, improved some of the analyzed parameters (approximately 24, 59 and 127% increase in shoot length, α-chlorophyll and zinc content, respectively). Results demonstrated that zinc-loaded PVA/Zein nanofbers are a promising material for to be used as seed coating, being able to improve crop performance.
