A doctoral dissertation conducted at Al-Musaib Technical College, one of the institutions of Al-Furat Al-Awsat Technical University, examined the topic entitled: “The Effect of Nano-Silicon on Growth, Yield, and Anatomical Characteristics of Three Soybean Cultivars under Different Irrigation Intervals” by the researcher Abbas Ghanem Hamza.
The study aimed to mitigate water stress through the use of nano-silicon and to determine the optimal response of soybean cultivars to stress conditions under the environmental conditions of Babil Governorate.
The results of the study indicated that the cultivar Shaimaa significantly outperformed others in yield, its components, and qualitative and anatomical traits, which was positively reflected in improved growth characteristics and increased productivity.
The findings also revealed that increasing the nitrogen content in leaves and seeds contributed to enhancing vegetative growth. Furthermore, the study demonstrated that the application of nano-silicon had a positive effect on most of the studied traits, with the concentration of 4 achieving the best results in terms of growth, yield, and quality traits. Additionally, reducing the irrigation interval to six days led to a significant improvement in the majority of the examined characteristics.
The study recommended the cultivation of the Shaimaa cultivar due to its superiority in yield, yield components, and qualitative and anatomical traits under the conditions of the study. It also recommended the use of nano-silicon at a concentration of 4 ml/L and an irrigation interval of six days, given their positive impact on improving growth, yield, and quality characteristics.
