When is the right time to apply potassium fertilizer to rice
Abstract The suitable times for applying potassium fertilizer to rice are the tillering stage, the young panicle differentiation stage and the booting stage. Applying potassium fertilizer at these three stages can effectively increase the seed-setting rate of rice, reduce pest and disease damage and increase yield. Combined application with phosphate fertilizer and nitrogen fertilizer can give full play to the effectiveness of potassium topdressing, among which the ratio of nitrogen, phosphorus and potassium is preferably 1 : 0.5: 1.2.

Why Mid-Season Sweet Potato Management Requires Heavy Potassium Fertilizer Application
This year, the sweet potato cutting period encountered drought, resulting in a low survival rate, so the planting density decreased somewhat, which will affect this year's sweet potato yield. Throughout its life, sweet potato has the greatest demand for potassium among all nutrients, especially when it enters the tuber bulking stage, when it needs a large amount of potassium. If potassium fertilizer is applied at this time
