How does sesame spread its seeds? A detailed explanation of its dispersal methods

Sesame seeds rely on ballistic ejection for dispersal. If sesame is not harvested after it passes the maturity stage, the moisture in the fruit hull will drop rapidly, and the fruit hull will become extremely dry and brittle, splitting open at the slightest disturbance from wind or movement and ejecting the seeds inside.

How is sesame planted?

1. Choosing the land

When planting sesame, choosing the land is the most important thing. Generally, planting starts right after the wheat harvest, because sesame is not afraid of heat. It likes high temperatures, so choosing the land is also crucial. Choose land that gets plenty of water, but it must not hold too much water; just keep the soil moist. Once the land is chosen, we do not start plowing. Then we sow. If sesame is planted in a place with many rainy days, then we should leave furrows to help with drainage.

2. Sowing

For sowing, you can directly scatter the seeds on the ground, which makes the seedlings emerge quickly. But it is not easy to weed. It is also not easy to water, and even harder to manage. So it is still recommended to sow with a machine. Machine sowing does not produce seedlings as quickly as broadcasting. But managing it row by row is more convenient. As long as temperature and humidity are ensured, seedlings can emerge in just over ten days.

3. Fertilizer and water

What matters most for getting a high yield of sesame is still fertilizing. Fertilizing must be done with a reasonable combination; you cannot just spread one kind of fertilizer, and you must also master the techniques and timing of fertilizing. Generally, sesame needs to be fertilized three times. Apply the first fertilizer right after the seedlings emerge; at this time the sesame seedlings are still small, so we had best use urea or manure. The second fertilizing should wait until sesame has just formed flower buds; at this time sesame has a relatively large nutrient demand and needs a sufficient supply of nutrients. The third is after flowering, and this one is the most crucial, because sesame grows fastest during the flowering period.

4. Management

What is there to manage but weeding? From seedling emergence to harvest, sesame must be weeded at least three times. Too many weeds absorb the nutrients, which affects the growth of sesame. If you find the soil is dry, water it in time, because sesame is afraid of dryness. If you find the soil is too wet, drain it quickly, because sesame is also afraid of waterlogging. If you find insects on the sesame, quickly buy insecticide and spray it. If all these things are done, then there is no need to worry that the sesame will not be high-yielding.
