Sesame, also known as til, is an important oilseed crop grown widely in India. It is valued for its high-quality oil, good market demand, and ability to grow even in poor soils and dry conditions. For farmers, getting a good yield from sesame depends a lot on proper sowing practices—especially using the right seed rate and maintaining correct spacing. These two factors directly influence plant population, growth, and final yield.
Sesame seeds are very small, so using the correct seed rate is very important. If too many seeds are used, the plants grow crowded, become weak, and compete with each other for sunlight and nutrients. If too few seeds are used, the crop stand becomes thin and yield reduces. For most sesame varieties, the recommended seed rate is 2–3 kg per acre. This ensures a good plant population and healthy growth. Farmers should always use clean, disease-free, and certified seeds for better germination and uniform crop growth.
To achieve uniform spacing, seeds should be mixed with sand or ash before sowing. This helps distribute the seeds evenly in the field. Sesame is mostly sown by broadcasting or by line sowing. While broadcasting is quicker, line sowing is always better because it ensures proper spacing and makes weeding, fertilizer application, and irrigation easier.
For line sowing, the recommended spacing is:
Rows: 30–45 cm apart
Plants within the row: 10–15 cm apart
This spacing gives the plants enough room to grow, branch properly, and produce more capsules. Wider row spacing of 45 cm is useful in regions with good rainfall or for tall varieties. In dry areas or when moisture is limited, farmers may choose closer spacing to ensure plants use available moisture effectively.
After the seeds germinate, farmers should thin the seedlings 10–12 days after sowing to maintain the correct spacing. Thinning helps remove extra plants that may have grown too close together. This prevents overcrowding and improves air circulation, reducing the chances of pests and diseases.
Sesame grows best when the soil has good drainage. Before sowing, the field should be prepared to a fine tilth with 2–3 ploughings. A smooth and firm seedbed ensures uniform seed placement and better germination. Seeds should be sown at a shallow depth of 1–2 cm because deeper placement reduces germination.
Seed rate and spacing also depend on the season. For kharif sesame grown during the monsoon, slightly wider spacing is recommended because the plants grow faster and taller. For summer sesame, closer spacing is preferred as the crop growth is more compact due to higher temperatures.
Proper nutrient and weed management become easier when the spacing is correct. With line sowing, farmers can apply basal fertilizers along the rows and use simple hand tools for weeding. This reduces crop competition and improves yield.
In simple words, sesame needs 2–3 kg seed per acre, with a spacing of 30–45 cm between rows and 10–15 cm between plants. Maintaining proper plant population helps the crop grow healthy, produce more capsules, and give higher yield. Using good seed, correct spacing, and timely thinning ensures a strong and productive sesame crop.
