“…Although Fedak and Mack (1977), Weston et al (1993), and Conry (1995) found that late seeding resulted in higher protein content of the grain, no effect of seeding date on protein content was found in our study (Table 5). This lack of response was unexpected based on the effects of seeding date on percent thins and test weight.…”

“…Weston et al (1993) also found that late seeding of barley resulted in lower kernel weight. Kernel numbers per spike and spikelet number per spike were not affected by seeding date, and cultivar differences were due to the differences between six-and two-rowed types for these traits (Table 6).…”

“…These findings support earlier studies done in other environments that indicated late seeding of spring barley results in reduced grain yields For personal use only. (Fedak and Mack 1977;Koz ⁄ lowska-Ptaszyńska 1993;Weston et al 1993). Lower grain yields may have been due to shorter vegetative and grain-filling periods (Table 3) resulting in lower kernel weights and tiller numbers per plant (Table 6).…”

“…The general response to seeding date for both spring and winter barley is reduced grain yields with late seeding (Fedak and Mack 1977;Baker and Gebeyehou 1982;Duczek and Piening 1982;Ciha 1983;Frank et al 1992;Koz ⁄ lowska-Ptaszyńska 1993;Weston et al 1993;Conry 1995;de Ruiter and Brooking 1996).

Juskiw, P. E. and Helm, J. H. 2003. Barley response to seeding date in central Alberta. Can. J. Plant Sci. 83: 275-281. Seeding date is an important factor influencing productivity of barley (Hordeum vulgare L.). When conditions are conducive to early seeding or result in delayed seeding, producers need to know how cultivars will respond to these seeding situations. In this study, five cultivars (Abee, Harrington, Jackson, Noble and Virden) registered for western Canada were studied for 4 yr (1990 to 1993) when seeded early (late April or early May), in mid-May, in late-May, or late (mid-June) at Lacombe, AB. For all cultivars, early seeding resulted in grain yield advantages of 113 to 134% of the mean site yield, while with late seeding, grain yields were reduced to 54 to 76% of the mean site yield. The reduction in yield was least for Jackson, the earliest maturing cultivar tested. Late seeding reduced the period from sowing to emergence, vegetative period, grain-filling period, time from emergence to physiological maturity, test weight, grain yield, kernel weight, and tillers per plant; and increased plant height and percent thins. Late seeding had no significant effect on phyllochron, stand establishment, scald, lodging, protein content of the grain, kernel number per spike, and spikelet number per spike. Barley responded positively to early seeding in central Alberta, but when seeding was delayed (in this study to mid-June) the early and mid-maturing six-rowed cultivars with short phyllochrons performed better than the two-rowed and late six-rowed cultivars.Key words: Hordeum vulgare L., seeding rate, phenological development, grain quality, grain yield, components Juskiw, P. E. et Helm. 2003. Réaction de l'orge à la date des semis dans le centre de l'Alberta. Can. J. Plant Sci. 83: 275-281. La date des semis influe considérablement sur le rendement de l'orge (Hordeum vulgare L.). Quand les conditions autorisent des semis hâtifs ou retardent ces derniers, il est essentiel de savoir comment les cultivars réagiront. Dans le cadre de cette étude, les auteurs ont examiné cinq cultivars (Abee, Harrington, Jackson, Noble et Virden) homologués pour l'ouest du Canada pendant quatre ans (de 1990 à 1993) et semés hâtivement (fin avril ou début mai), à la mi-mai, à la fin de mai ou tardivement (mi-juin) à Lacombe (Alberta). Les semis hâtifs augmentent le rendement grainier de tous les cultivars de 113 à 134 % comparativement au rendement moyen à cet endroit tandis que les semis tardifs le diminuent de 54 à 76 %. La baisse de rendement était la moins forte pour Jackson, le cultivar le plus précoce. Les semis tardifs réduisent le laps de temps entre la mise en terre et la levée, la période de croissance, la période de remplissage du grain, le laps de temps de la levée à la maturité physiologique, le poids spécifique, le rendement grainier, le poids de l'amande et le nombre de talles par plant; ils augmentent la hauteur du plant et le pourcentage d'éclaircissage. Les semis tardifs n'ont aucune incidence sensible sur le...

Barley yield and malt characteristics as affected by nitrogen and final irrigation timing

et al. 2022

Idaho is a major malt barley (Hordeum vulgare L.) producer in the United States. Production is concentrated in the semi‐arid Snake River Plain region of southern Idaho. Irrigation and fertilizer N applications are two of the most important managed factors. Research was conducted at the University of Idaho Kimberly Research & Extension Center near Kimberly, ID, to determine yield, grain quality, and malt characteristics as affected by N application rate (0, 56, 112, and 168 kg N ha−1) and final irrigation timing at Feekes 10.0 (boot; F10.0), Feekes 11.2 (soft dough; F11.2), and +7 d after Feekes 11.2 (+7F11.2). Irrigation termination at F10.0 resulted in decreased yields and unacceptable malt characteristics across N rates. Irrigation termination at F11.2 and +7F11.2 yielded 6,439 kg ha−1 at a fertilizer N application of 56 kg N ha−1, similar to higher N applications. Greater predicted yields up to 6,886 kg ha−1 were calculated by regression analysis with applications up to 147 kg N ha−1. Grain yield, protein, plumps, and test weights did not differ at any N rate for F11.2 or +7F11.2. Malt extract, free amino N, and diastatic power were similar for the F11.2 and +7F11.2 irrigations. Malt β‐glucan content did not differ up to 56 kg N ha−1 for any treatment, but reductions of up to 30 mg kg−1 were measured at higher N rates for the +7F11.2 irrigation. Results warrant further investigations into increased N applications and provide evidence of the effects of irrigation cutoff timing and N for malt barley.

The nitrogen use efficiency (NUE) is the ratio of the N uptake by the plant to the total amount of applied N fertilizer. The optimization of NUE is essential for sustainable agriculture, especially in the breeding programs to improve the yield of barley (Hordeum vulgare L.). We investigated the NUE variation in 32 barley genotypes and to examine the response relationship between phenotypic traits and N level to determine the traits essential for the selection of breeding programs to optimize the NUE. The NUE was investigated in 32 barley genotypes for 2 yr under field conditions using three N levels (60, 120, and 180 kg N ha −1 ). Growth, physiological and agronomic traits, and N efficiency-related parameters were determined. The parameters investigated were significantly affected by N application and its interactions with traits. Plant height, biological yield, spike length, and grain number (GN) were increased at higher N levels, but the 1,000-grain weight decreased. The lowest grain yield was 2,000.7 kg ha −1 at 60 kg N ha −1 , and the highest was 8,607.9 kg ha −1 at 120 kg N ha −1 . An increase in the N rate from 60 to 120 kg N ha −1 was associated with a higher total chlorophyll content (CHL SPAD ) (from 19.04 to 23.13), but no significant change in CHL was seen at 180 kg N ha −1 . The agronomic nitrogen use efficiency (ANUE), fertilizer N recovery efficiency and the nitrogen utilization efficiency were both reduced with an increase of the N application rate. A path analysis revealed that GN was the most essential trait for NUE breeding program selection due to its high direct effect (0.72) on ANUE. A linear discriminant analysis showed that CHL at 60 d after sowing was the best trait for distinguishing low from high N levels.
