How does sesame disperse its seeds?

How does sesame disperse its seeds? Sesame seeds are dispersed by ballistic ejection. If sesame is not harvested after it passes the mature stage, the water content of the fruit shell drops rapidly, and the fruit shell becomes extremely dry and brittle, so at the slightest disturbance it bursts open and ejects the seeds inside.

How is sesame grown?

1. Choosing the site

When growing sesame, choosing the site is the most important thing. Sesame is generally planted right after the wheat harvest, because sesame is not afraid of heat. It likes high temperatures, so choosing the site is also very important. Choose land that gets plenty of water, but it must not have too much water either; just keep the soil moist. Once the site is chosen, we do not start plowing. Then we sow. If sesame is grown in a place with a lot of rainy days, then we need to leave furrows to help with drainage.

2. Sowing

For sowing, you can simply scatter the seeds on the ground, which makes the seedlings emerge quickly. But it is not easy to weed this way. It is also not easy to water, and even harder to manage. So it is still recommended to sow by 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 will emerge in just over ten days.

3. Fertilizer and water

If you want high sesame yields, the most critical thing is still fertilizing. You need to learn to combine fertilizers properly; you cannot just spread one kind of fertilizer. You also need to master the techniques and timing of fertilization. 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 fertilization 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; this one is the most critical, because sesame grows fastest during the flowering period.
