The researchers studied how using YaraRega fertilizer on sweet sorghum plants affects their growth and yield. They tested two methods of applying the fertilizer and found that using the fertigation method with a 0.4% solution resulted in the best outcomes. Fertilizing with 40 kg of nitrogen per hectare led to a significant increase in fresh matter yield, with a 25% increase for the lower rate and 32% for the higher rate. The study showed that YaraRega can boost sorghum productivity without harming the plants.
