Sesame is a very valuable economic crop. If you want to obtain high yield during the harvest period, you have to pay attention to the fertilization of sesame, because the demand for sesame is large.

1. Seedling stage of sesame: The amount of nitrogen, phosphorus and potassium absorbed in the seedling stage accounts for 12.3%, 6.5% and 11.2% of the total growth and absorption, respectively, and is mainly used for the growth of leaves, stems and roots.

2. The current bud to the first flowering stage: The growth of sesame is accelerated during this period, but the increase in nutrient absorption is not large. The absorption of nitrogen, phosphorus and potassium is 17.5%, 13.6% and 17% of the total absorption, respectively.

3. Flowering period: sesame has the fastest growth of stems and leaves in the flowering period, and a large number of buds and capsules are formed. Nitrogen, phosphorus, and potassium absorption account for 43.9%, 34.0%, and 49.4% respectively. This period is the largest nitrogen and potassium nutrient. Efficiency period.

4. The mature period of sesame: the growth of vegetative organs such as stems and leaves slows down, the seeds in capsules form and tend to mature, oil or protein accumulates in the seeds, and the absorption of nitrogen, phosphorus and potassium still account for 26.3%, 45.9% and 22.4 respectively during the mature period %, Maintain proper nutrients, maintain metabolism in the body and prevent premature aging of plants.

Special fertilizer for sesame

Balance potassium sulfate such as: spraying slurry 14-16-15, 15-15-15; ammoniated potassium sulfate: 17-17-17
