“…It is widely accepted that smaller stems are more likely to ret uniformly and this is another potential benefit to increasing seeding rate. Increasing seeding rate did not significantly increase seed yields; this lack of response is similar to previous results (Albrechtsen and Dybing 1973;Gubbels and Kenaschuk 1989;Stevenson and Wright 1996;Lafond et al 2008). The smaller stems and higher fibre yield resulting from higher seeding rates indicate that seeding rate should be increased if the value of the extra fibre exceeds the cost of the seed.…”

“…This seed yield response was similar to the results of Lafond (1993), who found limited differences in seed yield at row spacings between 10 and 30 cm. Conversely, Stevenson and Wright (1996) and Alessi and Power (1970) found that yields were greatest with the narrowest row spacing. Fibre yields and number of stems did not differ between the two planting geometries ( Table 2).…”

“…Narrow row spacing has been shown to increase seed yields of flax in some studies (Alessi and Power 1970;Stevenson and Wright 1996), while other studies report narrow row spacing had little impact on seed yield (Lafond 1993). The desire to use wider row spacings in Western Canada is driven by the amount of direct seeding that is conducted, with most of these seeding systems sowing a band of seed less than 3 cm wide with row spacings of 20Á30 cm.…”

“…Seeding rates greater than the recommended rates of 400Á600 seeds m (2 did not affect seed yield (Gubbels and Kenaschuk 1989;Lafond et al 2008;Stevenson and Wright 1996). or produced a small increase (Hanson and Lukach 1990;Lafond 1993).…”

. 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...

“…Ainsi, Albrechtsen et Dybing (1973), Potts et Gardiner (1980), Casa et al (1999) et Easson et Molloy (2000) ont démontré que le taux de semis avait peu d'effet sur le rendement en grains du lin oléagineux. Lorsqu'il y a un contrôle des mauvaises herbes, Stevenson et Wright (1996) n'ont pas obtenu d'effet sur le rendement en grains avec des taux de semis de 300, 600 ou 900 grains m -2 . Cependant, dans un système de culture sans travail du sol, une augmentation linéaire du rendement en grains a été observée avec des taux de semis variant de 22 à 78 kg ha -1 (Lafond 1993).…”

[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.

Integrating agronomic practices can be useful in increasing flax (Linum usitatissimum L.) yield under biotic or abiotic constraints. A study was conducted to determine the combined effect of seeding density, row spacing, fertilizer, and fungicide application on no-till flax yields at three locations (7 site-years) in Saskatchewan and Manitoba, Canada. The four treatments were plant density; low (190 plants m -2 ) vs. moderate (320 plants m -2 ), row spacing; narrow (20 cm) vs. wide-row (40 cm), N rate; 65 vs. 130% of soil test recommendation, and foliar fungicide; pyraclostrobin + fluxapyroxad vs. no fungicide. No individual treatment parameter significantly affected yield; however, several combinations of treatments did. The combination of moderate density, narrow row spacing, 130% N, and fungicide application showed a 23% mean yield increase across all environments compared with the lowest-yielding combination. Still, yield ranking differed across different growing environments. The overall high-yielding combination was not productive under low-yielding environments. The same high-yielding combination, but with wide row spacing and the same combination with low density provided the most stable and moderate yield across all environments tested. Considering seed cost, yield advantage, and yield stability, the best combination was low density, narrow row spacing with 130% N and fungicide application. Among all practices, the combined application of 130% N and fungicide application significantly increased crop yield by 11% under all growing conditions. In the absence of negative interactions, producers can combine these four practices to increase flax yields depending on the cost.
