Linseed (Linum usitatissimum L.) belongs to family Linaceae, is the second most important rabi oilseed crop and stands next to rapeseed – mustard in area of cultivation and seed production in India. Flaxseed is grown as either oil crop or a fibre crop with fibre linen derived from the stem of fibre varieties and oil from the seed of linseed varieties. Several studies have been conducted on effect of fertilizers on growth and yield of linseed (Linum usitatissimum L.) varieties which revealed their enhancing role on the quality and quantity of flax cultivars. In this regards, a present study was planned and conducted during the Rabi season of 2020-2021 in the Agricultural field of School of Agricultural Sciences, Shri Guru Ram Rai University, Dehradun, Uttarakhand, India to investigate the effect of organic and biofertilizer and integrated treatment on the growth and yield of Linseed. The findings were reported on important growth and yield attributed parameters such as plant height, total fresh weight, total yield, 1000- seed weight (g), and number of seed / capsules. The maximum growth and yield was reported in T6 treatment where biofertilizer have been applied in consortium form followed by vermicompost. Thus, the findings revealed that all the microbial strains in consortia used as bio fertilizers showed enhanced tern of vegetative growth of plants, total herbage yield and total seed yield at various stages. This may be due to sustained release of nutrients to supply the required elements in microbial strains. The biofertilizers exhibited beneficial effects on plant growth and development either through producing growth hormones like IAA, kinetin and gibberellins, synthesizing atmospheric nitrogen and its increased availability to greater protein synthesis as well as increasing Phosphorus availability to plant communities. Thus, it was concluded that the enhanced expression of yield and its related attributes will have beneficial impact in production of nutraceutical products of commercial importance.

Flax Seeds

Flax (Linum usitatissimum L.), grown throughout the world for millennia. It is a multipurpose agricultural crop that can provide food, fuel and fibre. An agro-morphological characterization based on 13 traits of 26 flax accessions was carried out during the Rabi season 2017-2018 at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Rangpur. The field experiment was laid out in a randomized completed block design having four replications. Flax seeds were sown in 3.0 m × 0.6 m plot with continuous line sowing (two lines). The seed germination (%) and vigour indices of all flax accessions varied from 44.1 – 77.7 and 44.1 – 119.4, respectively. A significant variation in all growth and yield attributing descriptors was observed except 1000-seed weight of flax. Among the accessions, BD-10708 possessed the highest seed yield (182.9 g plant–1) and yield attributing descriptors viz., number of capsules plant–1 (142) and seeds plant–1 (513) of flax. The performance of the local accesson Ulipur was observed poor compared to some of the test accessions of flax. Some of these flax accessions could be used as breeding materials in varietal developmental and improvement programmes with higher yield potentials of flax in Bangladesh.

Being an important oilseed crop, flaxseed (Linum usitatissimum L.) grows mostly in temperate climates. The present study involved the seeds and seedlings of the flaxseed plant for analysis. The current experiment was carried out to determine the effect on seed germination, seedling growth and the antioxidant profiling of the plant when treated with heavy metal exposures. The heavy metals selected for the study were Zinc (Zn), Lead (Pb), and Copper (Cu). The inhibition caused by these metals varied from day to day as the experimental setup was upto 60 days and the observations started from the 15th day. The plant indicated inhibition on seed germination highest with Cu stress. The highest effect of heavy metal on reduced growth of shoot and root was exhibited by Pb and Cu stress. Also, when the antioxidant profiling was done, Zn had the most toxic effect on phytochemicals. The conclusions divulged that the metal toxicity was as follows: Pb > Cu >Zn.

Linum Usitatissimum L

Field experiments were conducted to determine the effect of mature crop residues and volunteer seedling residues of canola (Brassica napus L.), barley (Hordeum vulgare L.) and flax (Linum usitatissimum L.) on the growth and yield of subsequent flax crops seeded after conventional tillage. A second set of field experiments was also conducted which included both flax and barley as test crops on canola and barley stubble and included an additional comparison between conventional tillage and no tillage. Flax yields were generally lower on canola and flax stubble than on barley stubble with conventional tillage before seeding. Averaged over 6 yr the reduction was 9% on canola stubble. With no tillage prior to seeding, flax yielded as well on canola as on barley stubble. Spring volunteer seedlings of canola and flax often reduced flax yields but fall volunteer growth had no marked effect. Barley yielded better on canola than on its own stubble, and tended to yield better with tillage prior to seeding than without.Key words: Flax, Linum usitatissimum L., crop residues, phytotoxins, tillage practices

Intermediate Density

Field experiments were conducted in 1982 and 1983 to determine the effects of increasing densities (0–70 plants m−2) of volunteer wheat (Triticum aestivum L. Neepawa) and barley (Hordeum vulgare L. Bonanza) on the growth and seed yield of flax (Linum usitatissimum L. Dufferin). Rectangular hyperbolic models were fitted to data using nonlinear regression analysis. Results indicated that both volunteer cereals severely reduced flax biomass and yield, with volunteer barley interference causing greater losses than volunteer wheat at equivalent densities. From the regression equations it was calculated that an intermediate density of 30 volunteer wheat plants m−2 reduced the yield of flax by 49% in 1982 and 53% in 1983, whereas an equivalent density of volunteer barley plants reduced flax yields by 56% in 1982 and 67% in 1983.Key words: Competition, flax, volunteer wheat, volunteer barley, rectangular hyperbola, yield loss
