The study looked at different ways to fertilize tobacco plants to improve their growth and quality. By using a combination of base fertilizer and topdressing with real-time management, the plants had higher levels of nitrogen and potassium. This led to better efficiency in using these nutrients, higher yields, and improved quality of the tobacco leaves. The best method involved using 30% of the base fertilizer and applying real-time management for topdressing. This approach resulted in the highest yield and quality of tobacco plants, making it a suitable choice for tobacco production.
