Synthesis of nano-chitosan and its application as fertilizer and antifungal on potato

Abstract

This research aimed to use nanotechnology and its applications in agriculture, which gives broad prospects in the future to reduce the excessive use of fertilizers and pesticides and their negative effects on the environment. Therefore, chitosan nanoparticles loaded with nitrogen, phosphorous, and potassium were used as fertilizer and antifungal on potato plant to increase the yield and protect them from microbial infection, which increases the rates of their export from Egypt. The study was conducted in three parts, namely: 1- Preparation and characterization of chitosan nanoparticles loaded with nitrogen, phosphorous and potassium elements (Nano CS-NPK). 2- Using the foliar application of chitosan nanoparticles (Nano CS-NPK) as fertilizer for the purpose of studying the effect on growth, yield and physiological changes of the potato plants. 3- Study and evaluation the use of foliar spray with chitosan nanoparticles (Nano CS-NPK) as antifungal on the resistance of potato plants infected with Alternaria solani.
