in the presence of a good group of faculty members in some scientific departments and in the presence of postgraduate students. The scientific seminar included a set of axes that included an introduction describing the yellow corn crop and its economic importance and the importance of spraying with the compound Disper Size as it works to improve growth and yield in terms of increasing the percentage of pollination and then fertilization in the ovaries, by reducing the damage of temperatures during the flowering period, thus increasing the crop yield in the fall season. The student stated the goal of the study, which is to determine the best planting date for yellow corn in the fall season. And to determine the best concentration of nutrition with the compound Disper Size in increasing the production, size and quality of the plant, as well as determining the best interaction between planting dates and concentrations of the compound Disper Size. He also mentioned the method of measuring some of the characteristics of the study and explained the extent of their impact on the production of the yellow corn crop.
