The study looked at how different nutrient levels affect the growth and quality of turmeric plants. They tested 10 treatments with varying amounts of nutrients and found that adding a specific combination of nitrogen, phosphorus, and potassium led to the highest yield of turmeric rhizomes. The treatment with 25% more NPK than the control showed a 55% increase in curcumin content, which is a key component of turmeric's health benefits. Overall, the results showed that the right balance of nutrients can significantly impact the growth and quality of turmeric plants.
