Electrospun polymer nanocomposite membrane as a promising seed coat for controlled release of agrichemicals and improved germination: Towards a better agricultural prospect

This work was an attempt to boost crop productivity using biocompatible electrospun polycaprolactone nano -fiber seed coating on Zea Mays seeds with incorporation of synthesized nano hydroxyapatite (fertilizer high in phosphorus) and zinc oxide nanoparticles (micronutrients). The structure, morphology, and physical charac-teristics of the fabricated fibres were studied. A regulated release of nutrients from the fibre scaffolds was seen in the pH, conductivity measurements and metal release study. While in storage the seed is protected by the electrospun porous polymer nanofibrous membrane layer, which also enables water and gas exchange and en-hances the seed's ability to sprout. Early stages of seed germination are improved by the controlled rate of water absorption in polymer nanofibers covered seeds, as seen by studies of swelling and imbibition. According to statistical analysis, the presence of nutrients in the area around the seedling had a substantial impact on the stand establishment and germination percentage.
