What is the best fertilizer for sesame top-dressing
Sesame seedlings can use a small amount of nitrogen fertilizer as a base fertilizer. When the growth is poor, a small amount of seedling promotion fertilizer can be applied first, using diluted and decomposed human waste. During the flower bud differentiation stage, top-dressing should mainly be nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizers. In areas lacking boron, boron fertilizer should be applied. During the flowering period, the demand for nutrients increases, and chemical fertilizers should be used, or decomposed cake fertilizer, dung fertilizer, and livestock manure can also be applied.
Sesame top-dressing time
Sesame has a high demand for fertilizer during the flower bud differentiation period, as this is when both vegetative growth and reproductive growth are simultaneous, making this the best time for top-dressing.
What fertilizer to use for sesame top-dressing
Sesame prefers fertilizers high in nitrogen, so top-dressing should focus on nitrogen fertilizers, with phosphorus and potassium fertilizers as auxiliary. In areas where the soil lacks boron, boron fertilizer should be applied.
Generally, sesame should choose compound fertilizers high in phosphorus, root and tuber crops should choose high-potassium compound fertilizers, peanuts, sesame, oilseed rape, and chili peppers should choose compound fertilizers high in phosphorus, and leafy vegetables should choose fertilizers high in nitrogen.
Sesame top-dressing method
During the flowering period of sesame, which is from the initial to the full bloom stage, foliar top-dressing is required. Choose a sunny afternoon to spray diluted potassium dihydrogen phosphate on the leaves, applying it three times with an interval of 5-6 days. If it rains after spraying, it should be reapplied.
Sesame top-dressing principles
According to the laws of sesame top-dressing, the following principles should be followed: base fertilizer should be mainly organic, combined with an appropriate amount of potassium fertilizer. Since sesame has a shallow root system, sufficient base fertilizer should be applied. Top-dressing should also include phosphorus and potassium fertilizers, and foliar application after full bloom.
Precautions for sesame top-dressing
1. Seedling stage: When fertilizing sesame, the application of nitrogen fertilizer should be controlled to prevent excessive growth. Therefore, a small amount of nitrogen fertilizer can be used as a base fertilizer for sesame seedlings. When the growth is poor, a small amount of seedling promotion fertilizer can be applied first, using diluted and decomposed human waste.
2. Bud formation stage: Sesame in the flower bud differentiation period has a very high demand for fertilizer, and top-dressing at this time has a good effect. The top-dressing should focus on nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizers, and boron fertilizer should be applied in boron-deficient areas.
3. Flowering stage: During the flowering period of sesame, the frequency of fertilization can be increased, and heavy application of flower fertilizer is necessary to increase yield. At this time, lateral roots have begun to form in large numbers, absorption capacity has increased, and the demand for nutrients is also significantly higher, mainly using chemical fertilizers, or decomposed cake fertilizer, dung fertilizer, and livestock manure can also be applied.
