Abstract
A field experiment was carried out in the spring agricultural season of the year (2021-2022) in the fields of a farmer in Al-Sharqat district of Salah El-Din governorate using three genotypes of yellow sugar corn (Snowy River, Biotek/Talar, Aristo) to evaluate the response of the genotypes to the effect of spraying with three

Potassium levels are 0, 3000, 5000 and using the split plate system, the results are as follows:
1- The results were high for all traits studied in the levels of potassium fertilization, while the compositions differed between them at the level of probability of 1% for all traits, and the interaction between the levels of fertilization and genotypes was significant in the length of the ear.
2- The superiority of the third potassium fertilization in the characteristics of the ear diameter and the number of ear rows, while the first leaf of potassium exceeded 3000 ppm in the characteristic of ear length only.
3- There were significant differences in the average performance of the genotypes in the studied traits, as the hybrid (4×6) was distinguished in most of the traits that were studied, namely the length of the ear and the number of rows in the ear.
4- The interaction of fertilization levels and structures was significant, as the hybrid (1×6) was distinguished in most of the traits when the comparison treatment, and the number of ear rows at the second fertilization level was 5000 ppm.
