Production Technology of Linseed


Local Name: Jawas, Alshi, Tisi, Moshina.

Family: Linaceae.

Botanical Name: Linum usitatissimum.

Origin: Afghanistan.

Economic Uses

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

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 

·         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

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

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.

Sowing Time

Mid October – Mid November.

Seed rate

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 

Seed are treated with Bavistin @ 1.5 g/kg seed to control seed borne diseases.

Fertilizer Application

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 35­40 days after sowing.

Irrigation

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 

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 lit water/ha for Rust disease.

2.      Seed treatment with bavistin @ 1.5 g/kg seed for prevent wilt disease.

Harvesting

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

Winnowing is done to clean the grain from chaff. For fiber it is harvested at capsule maturity when the crop is still green.

Yield

1.      Rainfed crop: 300 to 500 kg/ha.


2.      Irrigated crop: 800 to 1000 kg/ha.

Methods of Fertilizer Application. https://cststudy.blogspot.com/ B.Sc.Ag. (Hons) Part-I  Methods of Fertilizer Application Fertilizer recovery is greatly influenced by method of its application. Method of application varies according to the spacing of crop, type of fertilizer material, time of application, etc. A brief account of these points could be explained as under : A.Method of application of solid fertilizer materials Solid materials may be applied in following ways: 1. Broadcasting Even and uniform spreading of dry solid fertilizers by hand or spreader over the entire field before or after sowing of the crop is termed as broadcasting. Well decomposed FYM, compost, oil cake, bone meal, urea, superphosphate and lime are applied by this method. Advantages This method is easy, less time taking, cheap and more convenient to the farmers. This method proves effective- i.                      When the crops have a dense stand ii.

Seed dormancy and its importance. https://cststudy.blogspot.com/                                                Seed Dormancy Definition:   The term dormancy refers to lack of growth in any plant part due to either internally or externally induced factors. Seed technologist use the term of refers to non-germination resulting from conditions within the seeds.  Dormancy is the state of inhibits growth of seeds or other plant organs as a result of internal causes not due to environmental condition. In other word, the unavailability of well developed mature, perfectly viable and healthy seed to germinate when placed under favorable conditions for germination is called dormancy or rest period of seed. Important of seed dormancy: 1. It is a mechanism which helps to survive this species. 2. It prevents the germination of seed in the field during production. 3. Dormancy helps to store the seed in the store house. 4. It contributes the congivity of the species.

Mango  Hopper.https://cststudy.blogspot.com/ Mango  Hopper 1. Idocerus alkinsoni. 2. I. niveosparus. 3. I. clypealis. Family : Cicadellidae. Order : Hemiptera. Nature of Damage 3 species of hopper causes serious damage to the inflorescence. Heavy laying on inflorescence causes  dropping and withering of the fruits. Both nymphs and adult suck juice from the flowers, resulting shedding  and withering of the flowers. In case of severe attack, honey dew secreted by the hoppers over the  inflorescence and leaves, giving rise to development. Shoote mold which hinders the setting of fruits. Lose  due to hoppers varies from 25­-60%. Life Cycle 1. The insect appear in large number during November to February as soon the flowers buds beginning to  form. 2. Female are lays egg on leaves flower stick and buds etc. Eggs are laid singly or batch. A female lays on average 200 eggs. 3. The egg hatch in 4­-7 days in winter and 2­-13 days in summer. 4.
