| Reproductive Phase | 45+ | Blooming, capsule formation |
| Ripening Phase | 95-110 | Physiological maturity, 75% of capsules have mature seeds |
The sesame plant lifecycle is full of interesting steps. Each step is important for a good harvest. By understanding these steps, farmers can grow sesame plants well. They can enjoy the benefits of this valuable crop.
Water Requirements for Sesame Plants
Sesame plants are known for being very drought-tolerant. They need less water than many other crops like cotton, corn, and soybeans. But, they do need enough moisture to grow well. The best way to water them is with a heavy soaking before and quick, light waterings during the growing season.
Too much water can harm sesame plants because they don’t like standing water. How much water and fertilizer they need depends on the local rainfall. For areas with less than 28 inches of rain a year, sesame needs 25-35 units of nitrogen per acre. If you irrigate them, they might need 60-80 units of nitrogen per acre to produce well.
| Sesame Water Requirement | Nitrogen Fertilizer Requirement |
|---|---|
| Dryland sesame (under 28 inches annual rainfall) | 25-35 units of nitrogen per acre |
| Fully irrigated sesame | 60-80 units of nitrogen per acre |
Sesame is one of the most drought-tolerant crops in the world. It’s great for growing in dry areas. With the right water and fertilizer, sesame farmers can get good yields from this tough and versatile plant.
“Sesame is a crop that can thrive with minimal water, making it a valuable option for sustainable agriculture in water-scarce regions.”
Fertilizing Sesame Seed Plants
Sesame is a deep-rooted crop that can find nutrients deep in the soil. But, it still needs balanced NPK fertilizers, especially when it flowers. To get the best sesame yields, using balanced NPK fertilizers is key.
Try applying half the nitrogen at the start of flowering. Sesame needs a lot of nitrogen during this time. The amount you need depends on the moisture, ranging from 25-35 units per acre for dryland sesame to 60-80 units per acre for irrigated sesame.
| Fertilizer | Nutrient Content | Recommended Application Rate |
|---|---|---|
| Single SuperPhosphate (SSP) | 19% P2O5 | 242.11 kg per hectare or 24.21 g per square meter |
| Muriate Of Potash (MOP) | 60% K2O | 20 kg per hectare or 2.0 g per square meter |
| Urea | 46% N | 40 kg N per hectare, applied in two splits |
Here’s how to apply these fertilizers:
- Urea goes with the first planting and again 4-6 weeks later.
- Single SuperPhosphate (SSP) is given once at planting because it doesn’t move much in the soil.
- Muriate Of Potash (MOP) gets split into two, once at planting and again during the first weeding.
Not all farmers have standard measuring tools. So, using body parts, 50kg fertilizer bags, everyday items, or basic farm tools can help estimate the right amount to apply.
“Sesame ranks sixth in the world production of edible oil seeds, producing approximately 3,312,986 million tons.”
Harvesting Sesame Seeds
Growing sesame sesame harvesting and sesame seed harvest are key steps. Sesame seeds take 78-85 days to grow before they’re ready. They turn from green to yellow to red when they’re fully ripe, usually 90 to 130 days after planting.
Getting the timing right is vital for a good sesame seed harvest. Harvest sesame seeds when they’re as dry as possible to avoid spoilage. They should have less than 10% moisture for storage to keep them fresh. Sesame seeds can last up to 5 years if stored properly.
Modern combines work well for sesame harvesting if set up right. The skill and experience of the operator are key. They must adjust the combine to reduce seed loss. Sesame seeds need to be dried to below 6% moisture before storage.
New sesame varieties that yield more and resist shattering have improved sesame seed harvest in the U.S. These varieties have helped overcome the issue of seed loss. With the right timing and equipment, growers can increase their sesame seed yields and have a successful harvest.
