The study looked at how nitrogen and potassium fertilizers affect enzymes that control starch production in wheat grains. Two wheat varieties were grown with different levels of nitrogen and potassium. Both varieties showed higher enzyme activity and starch content with fertilization, but one had more than the other. Nitrogen increased sucrose content and enzyme activity, while potassium increased amylose content. The right balance of nitrogen and potassium at a specific growth stage is crucial for starch formation. Overall, the enzymes SS, SSS, and GBSS play a key role in determining starch content in wheat grains.
