Linseed ,(experiment details) 2020

Effect of sowing date and planting geometry on growth, yield and quality of linseed under the North hill Zone of Chhattisgarh 

Introduction- Linseed (Linum usitatissimum L.), also known as flax is a member of genus Linum in the family Linaceae. It is commonly known as Alashi or Alsi. Every part of the linseed plant is utilized commercially, either directly or after processing. On a very small scale seed is directly used for edible purposes. It contains 33 to 47% of oil. About 20% of the total oil produced is used at farmer’s level and the rest 80% oil goes to industries in various forms such as boiled oil, borated oil, eposidized oil, aluminates oil, urethane oil, isomerizes oil etc. The oil is rich in linolenic acid (>66%) and it is a perfect drying oil. Linseed seeds contain high levels of dietary fiber as well as lignin, an abundance of micronutrient and omega-3 fatty acids. It is good in taste and contains 36% protein. It is also used as organic manure andcontains about 5% N, 1.4% P₂O₅ and 1.8% K₂O. In the world, it is cultivated over 24.37 lakh ha area with a production of 22.0 lakh tones and productivity 903 Kg/ha. In india linseed is cultivated in about 3.30 lakh hectares with contribution of 1.72 lakh tones to the annual oilseed production of the country. The average productivity of linseed is 523 kg/ha and it contributes 7 per cent to the world linseed production(Anonymous 2017) .Major linseed growing states in India are Madhya Pradesh, Uttar Pradesh, Chhattisgarh, Bihar, Rajasthan, Orissa and Karnataka.. At present Chhattisgarh cultivated over 28 thousand ha area with a production of 12.58 thousand tones and productivity of 446 kg/ha (3^rd Advance Estimates of DES, 2017-18)). It is a major crop grown as “Utera” during Rabi season. In Surguja district, linseed is cultivated over 3.016 thousand ha area with a production of 1.508 thousand tones and productivity of 500 kg/ha (State Chhattisgarh, Agriculture Contingency Plan for District Surguja,2017-18).

 OBJECTIVES- (1)To study the effect of different sowing  time on growth, yield and oil content of linseed.( 2)To study the effect on growth, yield and oil content of linseed under various planting geometry.(3) To find the interaction effect of different sowing time and planting geometry on growth, yield and oil content of linseed.

Technical programme of work :- :- The present experiment will be conducted at Instructional-cum-Research Farm, Rajmohini Devi College of Agriculture and Research Station, Ambikapur (C.G.) during Rabi 2019-20, which is situated at 23º10' North latitude and at an altitude of 623 meters above mean sea level (MSL).
