Modification of TEMPO-oxidized cellulose nanofibers as a source of potassium and its impact on onion plant

The influence of potassium nanoparticles as a foliar fertilizer on onion growth, production, chemical content, and DNA fingerprint

“…Furthermore, potassium promotes the volume of Allium cepa L. and root development [ 1 ] . Abd El-Aziz et al [ 21 ] reported that potassium carboxylate application based on cellulose nano-fibers as a nano foliar fertilizer increased onion production and enhanced the content of nutrients, photosynthetic pigments, protein, phenols, indoles, total soluble solid, lignin and cellulose. Ali et al [ 22 ] also found that the foliar spraying of nano NPK at a rate of 6 L/fedaan on onion plant cv Giza 6 gave the best values of plant length and production, while the maximum values of total exportable bulbs were gained using 75 % mineral fertilization and splattering with NPK nanoparticles at a rate of 6 L/fedaan.…”
