Foliar application of nano chitosan nitrogen, phosphorus and potassium (NPK) fertilizer decreased the life cycle of wheat plants with the ratio of 23.5% (130 days for yield production from date of sowing). Treatment of wheat plants with nano chitosan NPK fertilizer induced significant increases in all yield parameters, as compared with control yield parameters of normal non-fertilized and normal fertilized NPK wheat plants. Transmission electron microscopy investigations showed that nanoparticles were present in phloem tissues which mean that nanoparticles were taken up and transported through phloem route from leaves to stem down to roots. Clay-sandy soil showed better results than those obtained for clay soil. Foliar application of nano fertilizer to wheat plants proved to be important to improve yield parameters of wheat plants and shorten the life cycle of the crop.
