The study looked at how applying potassium at different stages of rice growth affects yield and grain production. Results showed that using a balanced ratio of potassium in both basal and panicle fertilizers led to the highest yield, while applying only basal fertilizer resulted in the lowest yield. The balanced potassium application helped increase the number of grains per panicle and overall yield by over 19%. This suggests that timing and distribution of potassium fertilizer play a crucial role in maximizing rice production.
