The study looked at different types of spring wheat to see how well they use nitrogen in sandy soil. They tested 16 wheat genotypes with different levels of nitrogen for 2 years. Some genotypes were better at using nitrogen efficiently and had higher grain yield. The genotypes with high nitrogen use efficiency had more plant biomass, higher grain and straw nitrogen concentration, and heavier grains. The study found that Line 6052, Shandawel 1, Gemmiza 10, Gemmiza 12, Line 6078, and Line 6083 were the best performers in terms of grain yield. The researchers suggest that breeding programs should focus on improving nitrogen use efficiency to increase grain yield in wheat.
