How Are Sesame Seeds Harvested: A StepbyStep Guide
How Are Sesame Seeds Harvested?
Sesame seeds are harvested when the plants have reached maturity, which typically occurs 90-150 days from planting.
The harvesting process involves waiting for the leaves and stems of the sesame plants to change color and start dropping leaves, a stage known as ‘drying down.’ Once the stem and upper seed capsules have lost their greenness, the ripe seed capsules split open and release the seeds, a process called shattering.
For larger-scale cultivation, combines are often used to harvest sesame seeds, with any holes in combines and trucks being sealed with duct tape to prevent seed loss.
In home gardens, sesame seeds can be collected before splitting by drying the pods in a brown paper bag.
The dried pods can then be broken up to collect the seeds, which are then separated from the chaff before being stored in an airtight container.

Sesame Seed Harvesting Process
Sesame seeds have a rich history that spans over 4,000 years, making them one of the oldest cultivated crops. These warm-season annual plants are known for their ability to tolerate drought, making them ideal for regions with hot and dry conditions. Sesame seeds were introduced into the United States in the 1930s, and since then, their cultivation has gained popularity.
The process of harvesting sesame seeds typically occurs 90 to 150 days after planting. As the plants mature, their leaves and stems undergo a noticeable change in color and leaves start to drop. This transition is a significant indicator that the sesame plants are approaching readiness for harvest. One essential step in the harvesting process is allowing the greenness of the stem and upper seed capsules to disappear. This state is commonly referred to as “drying down,” and it ensures that the seeds are as dry as possible for optimal storage and later use.
Ripe sesame seed capsules eventually split open, releasing the seeds. This natural process is known as shattering. To harvest sesame seeds on a larger scale, farmers often employ the use of a combine, a farming machine that efficiently cuts and separates the seeds from the plants. However, it’s important to note that when using combines and trucks in sesame seed harvesting, any holes are carefully sealed with duct tape to prevent loss during transportation.
In home gardens, the collection of sesame seeds can be done before shattering occurs. This can be achieved by placing the pods in a brown paper bag to allow them to dry out. Once the pods are completely dry, any unsplit seed pods can be gently broken to release the seeds. These seeds can then be separated from any remaining plant material, known as chaff, and stored in an airtight container for later use.

Cultivation And Growth Of Sesame Plants
Sesame plants, known for their resilience and adaptability, are often referred to as “survivor” crops. They possess the remarkable ability to tolerate drought and thrive in hot and dry conditions, making them suitable for cultivation in diverse regions around the world. Sesame seeds are grown in pods on the sesame plant, which typically grows to around two feet tall and has vibrant light-colored flowers.
The growth of sesame plants follows a specific timeline. Once the seeds are planted, they go through a germination period that typically takes around one to two weeks. As the plants continue to develop, they produce leafy foliage and begin to flower. Within 125 to 135 days of planting, inch-long seed pods start to form on the plant. These pods gradually open when they reach maturity, allowing the sesame seeds to be released naturally.
During the cultivation process, sesame plants require sufficient water and nutrients. While their drought tolerance is notable, consistent watering throughout the growing season is crucial to ensure optimal plant health and seed development. Additionally, farmers need to monitor and manage any pests or diseases that may pose a threat to the plants.

Harvesting Techniques For Sesame Seeds
The harvesting of sesame seeds involves techniques aimed at maximizing seed yield and quality. Once the signs of readiness for harvest appear, it is essential to time the process carefully to ensure the seeds are at their peak dryness and flavor. Harvesting can be done on both small and large scales, with different methods employed depending on the resources available.
On a larger scale, farmers often rely on combines, which are efficient machines designed to cut and separate the sesame seeds from the plants. These combines offer the advantage of streamlining the harvesting process, minimizing the need for manual labor. However, careful attention is given to sealing any holes in the combines and trucks used for sesame seed harvesting to prevent any loss during transportation.
In home gardens or smaller-scale operations, the focus is on individual pod collection. Sesame seeds can be collected before shattering occurs by placing the pods in a brown paper bag and allowing them to dry out thoroughly. Once the pods are completely dry, any unsplit seed pods can be gently broken to release the seeds. These seeds can then be separated from the chaff, the remaining plant material, and stored in an airtight container for future use.

Frequently Asked Questions
How do you get sesame seeds?
To obtain sesame seeds, one must harvest the oblong pods of the sesame plant. After the fruit is collected, it undergoes a drying process that prompts the pod to crack open slightly. This cracking allows for the simple extraction of the small oval seeds that lie within. By shaking the dried fruit, the delicious sesame seeds are effortlessly released, ready to be enjoyed or used in culinary endeavors.
What is the process of sesame seeds?
The process of extracting sesame seeds begins with a preliminary cleaning and grinding phase, which helps remove any impurities and debris. This step prepares the seeds for the subsequent dehulling process. Once the seeds are ready, a hot lye treatment is applied to facilitate the removal of the seed husk. This treatment effectively breaks down the husk, making it easier to separate from the seed. Following this, the skin and pigments are removed, enhancing the appearance and quality of the sesame seed. Thorough washing and drying complete the process, ensuring that the seeds are clean and ready for various culinary and industrial applications.
How is sesame farmed?
Sesame farming involves a precise process to ensure optimal growth. The seeds are typically planted at a depth of 0.75 to 1.5 inches, followed by a necessary period of moist soil for about 3 to 5 days. It is essential to maintain minimal planting depth and soil compaction. To achieve an ideal sesame crop, a recommended planting rate of 3 pounds per acre, or approximately 25-35 seeds per foot, is advised, especially when utilizing a 40-inch row spacing. By carefully following these guidelines, farmers can maximize the yield potential and quality of their sesame harvest.
How are sesame seeds dispersed?
Sesame seeds are dispersed through a fascinating process that involves their capsules drying and splitting open. As the capsules mature, they undergo a hygroscopic movement, meaning they respond to changes in moisture levels. This hygroscopic action causes the capsules to open, releasing the rows of seeds within each locule. Once the capsules open, the seeds are then free to disperse and spread to new locations, aiding in their successful reproduction and expansion.
