The student mentioned the aim of the study, which is to study the effect of spraying with silicon and to know the best concentration of it on the growth and crown of yellow corn and to study the interaction between the study factors and their effect on the growth and productivity of yellow corn in addition to studying the possibility of reducing the fertilizer recommendations (N), (P) and (K) by using humic acids and spraying silicon. He also mentioned the method of measuring some of the characteristics of the study and explained the extent of its effect on the production of the yellow corn crop.
