Cultivation Of Linseed
knowledge EscalationMay 21, 2023Botanical name: Linum usitatissimum Chromosomes number: 2n = 30
Origin:
Linseed, also known as flaxseed, is believed to have originated in the Mediterranean region and Western Asia.
Geographical distribution:
Linseed is cultivated in several countries around the world, including Canada, Russia, China, India, the United States, and various European countries.
Economic importance:
Linseed is primarily cultivated for its oil-rich seeds, which are used in various industries. The oil extracted from linseed is used in food products, paints, varnishes, and as a drying agent in oil-based paints. Linseed fibers are also used in the production of linen fabrics and papers.
Soil and climatic requirements:
Linseed grows best in well-drained loamy soils with a pH ranging from 5.5 to 7.5. It prefers cool and temperate climatic conditions. The ideal temperature range for growth is between 15°C and 25°C. Linseed requires a moderate amount of rainfall, preferably evenly distributed throughout its growth period.
Seed rate:
The recommended seed rate for linseed is about 40 to 45 kilograms per hectare.
Spacing:
A row-to-row spacing of 22 to 30 centimeters is suitable for linseed cultivation.
Seed treatment:
Before sowing, linseed seeds can be treated with fungicides to protect against seed-borne diseases. It is advisable to consult local agricultural authorities or experts for specific seed treatment recommendations based on the prevailing conditions in your region.
Varieties:
There are several varieties of linseed available, and the choice of variety depends on factors such as local climate, disease resistance, and market demand. Some popular linseed varieties include Neelum, T-397, JL-24, and Pusa 26.
Cultural practices:
Here are some general cultural practices for linseed cultivation:
1. Land preparation: Prepare the land by plowing and harrowing to achieve a fine tilth.
2. Sowing: Sow the seeds in rows at the recommended spacing. The best time for sowing depends on the local climate and can vary, but generally, it is done during the rabi season (October to December).
3. Irrigation: Provide sufficient moisture to the crop during the critical growth stages. Linseed requires about 4 to 5 irrigations during its growth period.
4. Weed control: Control weeds through regular manual or mechanical weeding and the use of herbicides, if necessary.
5. Disease and pest management: Monitor the crop regularly for any signs of diseases or pests. Use appropriate fungicides or insecticides as recommended by experts or agricultural authorities.
6. Harvesting: Harvest the linseed crop when the capsules turn brown and start to split. Cut the plants close to the ground, and allow them to dry in the field.
7. Threshing and storage: After drying, thresh the plants to separate the seeds. Store the seeds in a cool and dry place to maintain their quality.
Yield:
The yield of linseed can vary depending on various factors such as variety, soil fertility, climatic conditions, and management practices. On average, a well-managed linseed crop can yield around 10 to 15 quintals per hectare.
Control measures
- Avoid continuous cultivation of linseed in the same field
- Sowing may be resorted 10-15 days earlier to minimize the bud fly infestation
- Selection of suitable variety with tolerance to the major pests and diseases
- Use of light trap for bud fly; Use of attractant (1 kg Gur-Rabi in 75 lit. of water) for bud fly; Use of bamboo/wooden pegs as dead perches for predatory birds;
- Seed should be treated with Bavistin @ 1.5 g/kg seed or Thiram @ 3 g/kg seed orTopsin-M @ 2.5 g/kg seed to protect the crop from seed-borne diseases and to some extent from soil borne diseases also.
- Two application of neem based commercial formulation containing Azadirachtin 300 ppm reduces upto 63% bud infestation and thereby enhancement upto 40% in seed yield.
