How to Grow Linseed/Production Technology of Linseed
Local Name: Jawas, Alshi, Tisi, Moshina.
Botanical Name: Linum usitatissimum.
Economic Uses of Linseed
1. Linseed is important oil seed as well as fiber crop.
2. In India it is mainly grown as oil seed crop and oil is used for culinary purpose.
3. The oil is drying hence mainly used for manufacturing paints, varnishes, oil cloths etc.
4. Oil cake is used as manure and cattle feed. 5. Seed is used for making chutnees.
6. In western countries it is mainly grown for fiber purpose for making linen goods.
7. Oil content of the linseed is about 35 to 42%.
Varieties of Linseed
Some of Indian varieties are Malshiras–10, Sholapur– 36, N– 55, C– 429, RLC– 4 (Jagdamba). Nela is the approved variety in Bangladesh.
Climatic Requirement of Linseed Production
· Linseed is a cool and dry season crop.
· The temperature ranging between 100C to 250C is good for growth.
· It is a drought resistant crop and grown as rainfed crop is areas receiving 650 to 1000 mm rainfall.
· It cannot tolerate heavy rains during growth periods.
Soil Requirement of Linseed Production
Linseed can be grown on different types of soils except sandy and heavy clay. But it grows best in water retentive alluvial and deep black soils with good drainage. It is exhaustive crop and soil become linseed sick, if crop is grown on same field year after year.
Preparation of Land for Linseed Production
Land is prepared by frequent harrowing in kharif when taken as first crop. Land is cleaned off by collecting and destroying the stubbles. 4-5 Ploughing and cross Ploughing is done for linseed cultivation. 2-3 laddering is done in this time.
Mid October – Mid November.
1. For small seeded varieties: 10 to 15 kg/ha.
2. For big seeded varieties: 20 to 24 kg/ha. Spacing 22 cm X 10 cm.
Seed treatment for Linseed Production
Seed are treated with Bavistin @ 1.5 g/kg seed to control seed borne diseases.
Fertilizer Application of Linseed Production
Linseed is generally not manured. But application of 40 kg N/ha. is recommended for getting better yield. Out of this 20 kg N is given at the time of sowing and remaining 20 kg N is given 35-40 days after sowing.
Irrigation for Linseed Production
Generally linseed crop is taken as rainfed crop on the residual moisture. If sufficient moisture is not available in soil at the time of sowing, presoaking irrigation should be given. If irrigation facilities are available than two irrigations may be given. One at flowering stage and another at seed developing stage.
Pest and disease control of Linseed
Important Pests of Linseed are Linseed Gall Fly, Linseed caterpillar.
1. Spraying of 0.05% endosulfan or 0.03% Dimethoate for linseed gall fly.
2. Spraying of 0.05% Malathion or endosulfan for linseed caterpillar.
Important Diseases of Linseed are Linseed Rust, Wilt.
1. Spraying of dithane M45 @ 1250 gm in 500 litre water/ha for Rust disease.
2. Seed treatment with bavistin @ 1.5 g/kg seed for prevent wilt disease.
Harvesting of Linseed
Maturity: Linseed crop matures within 100 days after sowing. Harvesting is done when plant turn golden yellow and the capsules turn brownish and begins to dry up and open.
Method: The crop is harvested by pulling or cutting the plants at base. The plants are stacked on the threshing floor to dry. When most of the capsules are opened, threshing is done by beating with a stick or by trampling under the feet of bullocks.
Post-harvest operation of Linseed
Winnowing is done to clean the grain from chaff. For fiber it is harvested at capsule maturity when the crop is still green.
Yield of Linseed
1. Rainfed crop: 300 to 500 kg/ha.
2. Irrigated crop: 800 to 1000 kg/ha.
