A master's dissertation was discussed in the College of Agriculture, University of Al-Qadisiyah on the effect of spraying Nano NPK fertilizers, elements and Nano amino acids on the growth of yellow corn by the postgraduate student, Mrs. Safa Abd Al-Amir Mawat. The dissertation reviewed the effect of balanced, high-potassium NPK foliar spray on the quantitative and qualitative growth indicators of the maize plant. The dissertation highlighted the superior moral role of high-potassium Nano NPK foliar spray recording to the highest averages of chlorophyll content in leaves, stem diameter, grain yield, biological yield, harvest index, ready potassium content in the soil after harvest and the common role between balanced or high-potassium NPK with Nano-trace elements and Nano-amino acids. The dissertation demonstrated that the NPK high-potassium foliar spray and the balanced Nano NPK are the best in achieving the highest yield and qualitative characteristics of the yellow corn plant, as well as reviewing the effectiveness of Nano-elements with Nano amino acids as qualitatively complementary foliar fertilizers in raising plant indicators in terms of quantity and quality.
