A master’s thesis at the College of Agriculture, University of Kerbala, discussed the effect of mineral fertilization (NPK), humic acid, and foliar application of silicon on growth indicators and productivity of yellow maize. The thesis, presented by student Ahmed Qasim Abdul Azeebi, was attended by faculty members, postgraduate students, and researchers.
The thesis, titled “The Effect of Mineral Fertilization (NPK), Humic Acid, and Foliar Application of Silicon on Some Growth Indicators and Yield of Yellow Maize”, examined the impact of reducing the amount of mineral fertilizers in combination with humic acid and silicon to enhance crop growth.
The study aimed to evaluate the possibility of reducing the quantity of mineral fertilizers (NPK) by half when combined with humic acid and foliar spraying of silicon, and to investigate the effects of these treatments on improving the growth and productivity of yellow maize.
The results indicated that the highest yield of yellow maize could be achieved using only half the usual amount of mineral fertilizers when supplemented with humic acid and silicon, contributing to cost savings and improved agricultural efficiency.
