“…Likewise, varying seed rates significantly influenced plant population, pods/plant and grain yield/plant (Achakzai and Taran, 2011). According to several authors (Gubbels and Kenaschuk, 1989;Mostafa and El-Deeb, 2003;Lal et al, 2012;Abd El-Mohsen et al, 2013) increasing seed rate significantly decreased growth and yield attributes of linseed crop. On the other hand, seed rate did not show significant influence on all yield components considered under broadcasting (Table 4).…”

The effect of seed rates on yield and yield components of linseed were studied in South-Eastern Highlands of Ethiopia at four locations during 2012/13 and 2013/14 which are main-cropping seasons. Randomized complete block design with three replications was used for row planting and 10m by 10m plots were used for broadcasting. The linseed variety 'Kulumsa-1' was used and sown at seed rates (kg/ha) of nine levels for row planting and six seed rate (kg/ha) levels were used for broadcasting. Results showed significant (P≤0.05) effects of seed rates were observed on all yield components reflecting the importance of seeding rate for linseed growth, yield and yield components. However, significant (P≤0.05) effects of seed rates were not observed on all yield components except on number of pods/plant in the case of broadcasting. The highest seed yield was recorded from 40kg/ha (2019kg/ha) and 70kg/ha (1908kg/ha) for row planting and broadcasting, respectively. This data depicted that 6% (111kg/ha) seed yield advantage was obtained by using row planting method as compared to broadcasting. Similarly by using 30kg/ha and 40kg/ha seed rates increased seed yield/ha by 6% (110kg/ha) and 9% (162kg/ha), respectively as compared to 15kg/ha in the case of row planting. Similarly, using 70kg/ha seed rate for broadcasting resulted in 6% (102kg/ha) and 7% (126kg/ha) seed yield advantage as compared to 30kg/ha and 40kg/ha seed rates, respectively. The results of economic analysis indicated that the highest net benefits were obtained by using a seed rate of 30 to 40kg/ha for row planting and 70kg/ha for broadcasting.

“…Turner (1991), Gubbels et Kenaschuk (1989), Diepenbrock et al (1995) ont également obtenu des rendements en grains plus faibles et une verse importante lorsque le taux de semis était très élevé. Hanson et Lukach (1990) ont indiqué qu'une augmentation des taux de semis a permis l'obtention de rendements en grains plus élevés seulement lorsqu'il y a absence de verse.…”

“…D'après les travaux de Hanson et Lukach (1990), la densité optimale a été d'environ 860 plants m -2 mais ils ont également suggéré que la population minimale devrait être de 506 plants m -2 . Cependant, Freer et Sansome (1991) ont obtenu les rendements les plus élevés avec une population de 342 plants m -2 tandis que Gubbels et Kenaschuk (1989) ont obtenu un rendement optimal avec une population de 600 grains m -2 . D'autres travaux ont plutôt obtenu des réductions du rendement en grains suite à une augmentation de la densité de population.…”

[2000][2001][2002]. During 2 yr, grain yields increased with higher seeding rates. However, in 2001, there was a yield reduction with the increment of the seeding rates. In 2000 and 2002, nitrogen fertilization had no effect on grain yields. In 2001, grain yields decreased as nitrogen fertilization increased. During this test, yield reduction caused by high seeding rates or nitrogen application seemed to be associated with lodging. Seeding rate and nitrogen fertilization had little effect on mineral composition of the grain. These results indicate that a seeding rate of 40 kg ha -1 and low nitrogen fertilization rates could be adequate for oilseed flax production in a cool climate.

. 2010. Impact of production practices on fiber yield of oilseed flax under Canadian prairie conditions. Can. J. Plant Sci. 90: 61Á70. Flax (Linum usitatissimum L.) cultivars commonly grown in western Canada have been developed primarily for seed production. These cultivars tend to be shorter, have lower fibre content, and have lower above-ground biomass than cultivars developed specifically for fibre production. Linseed production is the dominant flax product in western Canada and fibre is a co-product of oilseed production. The objectives of these studies were to evaluate the effects of northern European fibre flax production practices under western Canadian soil and climatic conditions. A number of cultivars in narrow band and solid-seeded planting geometries to determine if they had similar responses. When flax was planted at recommended seeding rates for linseed production, seed and fibre yields were not affected by planting geometry. Increasing the seeding rate from 40 to 120 kg ha Á1 did not affect seed yield regardless of location or seeding date. Even though fibre content was not affected by seeding rate, higher seeding rates increased stem numbers, decreased stem size, reduced the variability in stem size and increased fibre yield. Delaying planting until the end of May increased fibre yields by an average of 35% with no corresponding decrease in seed yield. Since the relative seed and fibre yield responses of a wide range of cultivars were similar with solid seed and narrow band planting geometries, plant breeders can effectively select for higher fibre producing lines using narrow band seed openers using row spacings up to 30 cm apart.Key words: Linseed, row spacing, seeding rate, cultivar, fibre, fibre Irvine, R.

Incidence des pratiques culturales sur le rendement en fibres du lin dans les Prairies canadiennes. Can. J. Plant Sci. 90: 61Á70. Les varie´te´s du lin (Linum usitatissimum L.) couramment cultive´es dans l'ouest du Canada ont essentiellement e´te´de´veloppe´es pour la production de graines. Ces cultivars sont plus trapus et moins fibreux, et ont une plus faible biomasse ae´rienne que les cultivars cre´e´s pour la production de fibres. Les graines demeurent le principal produit tire´du lin dans l'Ouest canadien, les fibres constituant un sous-produit de l'extraction de l'huile. L'e´tude devait pre´ciser l'incidence des pratiques du nord de l'Europe servant a`produire de la fibre de lin en sol canadien, dans les conditions climatiques propres a`l'Ouest du pays. Plusieurs varie´te´s ont e´te´seme´es en bandes e´troites et en culture dense pour ve´rifier comment elles re´agiraient. Quand on se`me le lin aux densite´s recommande´es pour la production grainie`re, la ge´ome´trie de la plantation n'a aucune incidence sur le rendement en graines ou en fibres. Augmenter la densite´de semis de 40 a`120 kg par hectare ne modifie pas le rendement grainier, peu importe l'emplace...
