Nutritional elements for the growth and development of sesame

The roots of sesame and the green bodies on the ground absorb nutrients and water from the soil and air, decompose and synthesize in the body, and become various nutrients needed for growth and development. The overall trend of nutrients in the aboveground part of sesame from large to small is nitrogen, silicon, calcium, magnesium, potassium, phosphorus, aluminum, iron, sodium and manganese. In the upper part of the field, nitrogen, phosphorus and potassium are equal to 8.61: 1: 2.23. It shows that the growth and development of sesame requires a large amount of nitrogen, phosphorus and potassium fertilizer, but other elements are also indispensable, especially in silicon, calcium, magnesium, boron and so on.
