“…Spring grain yields were significantly reduced with later planting dates which agrees with previously reported results in other regions of North America (1,4,5,7,8,10,11,13). However, the significant cultivar X seeding date and cultivar X seeding date X year interactions for grain yield indicate the need to examine new cultivars under various seeding dates.…”

Over the past 15 to 25 years the plant characteristics of small grains have changed; however, little is known in the Pacific Northwest about the production practices necessary to maximize grain yields with these short statured, early maturing, lodging resistant small grain cultivars. A 4‐year (1977 to 1980) field study at Pullman, Wash. on a Palouse silt loam (fine‐silty, mixed, mesic pachic Ultic Haploxerolls) examined grain yield and test weight responses to three seeding dates (early, normal, and late) and three seeding rates (40, 75, and 110 kg/ha). Five spring barley (Hordeum vulgare L.), three spring oats (Avena sativa L.), and five spring wheat (Triticum aestivum L.) cultivars were tested. Significant cultivar × seeding date and cultivar × seeding date × year interactions existed for grain yield. Seeding date delays past the normal date significantly reduced grain yield and test weight for the majority of the cultivars when averaged over the 4‐year period. However, several cultivars showed yield reductions with seeding date delays past the earliest date. Several cultivars showed yield reductions with the lowest or highest seeding rate. Reduced yields with the 110 kg/ha seeding rate were caused by lodging. The non‐significant seeding rate × seeding date and cultivar × seeding rate × seeding date interactions for yield indicate that increasing the seeding rate with later seeding dates was not beneficial in increasing grain yield. Test weight values for the small grains averaged over years were generally reduced with late seeding dates.

“…Delayed seeding reduced grain yield at all but one site in this study, consistent with previous reports (Beard 1961;McFadden 1970;Ciha 1983;Lauer and Partridge 1990;Juskiw and Helm 2003). The average yield loss of 20% at the latest seeding in this study was less than observed in Minnesota (35%, Beard 1961) and central Alberta (47%, Juskiw and Helms 2003), likely due to the shorter time period between the first and last seeding dates in this study (≈ 3 wk) than in the latter studies (5 to 6 wk).…”

“…Typically, the highest grain yields are achieved with the earliest feasible seeding date, with initially a gradual decline, then a much more rapid decline when seeding is delayed (Beard 1961;McFadden 1970;Ciha 1983;Lauer and Partridge 1990;Juskiw and Helm 2003). The impact of delayed seeding on grain yield varies among years and cultivars (Ciha 1983;Juskiw and Helm 2003).…”

2005. Fertilization, seeding date, and seeding rate for malting barley yield and quality in southern Alberta. Can. J. Plant Sci. 85: 603-614. Weather conditions are often unfavourable for malting barley quality in southern Alberta, but agronomic practice may improve the probability of attaining acceptable quality. The objective of this study was to determine optimum agronomic practice (cultivar, fertilization, seeding date and seeding rate) for yield and quality of malting barley in southern Alberta. Field trials were conducted at 12 dryland sites and 2 irrigated sites over a 3-yr period (2001)(2002)(2003). At each site, five experiments were conducted with the following treatments: (1) N rate (0, 40, 80, 120, and 160 kg N ha -1 ), (2) P rate (0, 6.5, 13 and 19.5 kg P ha -1 ), (3) K rate (0, 25 and 50 kg K ha -1 ), (4) S rate (0, 10, and 20 kg S ha -1 ), and (5) seeding date (three dates at 10-d intervals) and seeding rate (150, 200, 250, 300, and 350 viable seeds m -2 ). Seven cultivars were included in the first experiment and two cultivars were included in the remainder of the experiments. Maximum grain yields were achieved when fertilizer + available soil N (estimated from unfertilized grain N yield) exceeded 31 kg N Mg -1 maximum grain yield, whereas protein concentrations were usually acceptable if fertilizer + available soil N was between 25 and 40 kg N Mg -1 maximum grain yield. Higher N rates generally reduced kernel size. Cultivar differences in N response were negligible. Application of P, K, or S did not affect malt yield or quality. Seeding delays of ≈20 d reduced grain yields by an average of 20%, with relatively greater yield declines under drought stressed conditions. Delayed seeding did not affect or slightly increased grain protein concentration. Kernel size was both increased and decreased by delayed seeding. Increased seeding rates from 150 to 350 viable seeds m -2 generally provided small yield gains, slight reductions in grain protein concentration and reduced kernel size. The most beneficial agronomic practices for malt barley production in southern Alberta were early seeding and application of N fertilizer at rates appropriate to the expected availability of moisture and soil N. . La première expérience portait sur sept cultivars auxquels deux autres se sont rajoutés par la suite. Le rendement atteint un maximum quand le N de l'amendement plus le N disponible dans le sol (estimé d'après le rendement grainier sans fertilisation) dépassent 31 kg de N par mg de rendement grainier maximal, alors qu'on obtient une concentration en protéines généralement acceptable quand la somme des deux sources de N se situe entre 25 et 40 kg de N par mg de rendement grainier maximal. Une concentration d'azote plus élevée réduit habituellement la taille du grain. Les cultivars réagis-sent tous à peu près de la même façon à l'azote. L'application d'amendements P, K ou S ne modifie ni le rendement ni la qualité du grain pour la brasserie. Un retard de ≈ 20 jours dans les semis réduit le rendement grainier d'en...

“…Planting date and N fertilizer significantly affect spring barley grain yield, grain protein and kernel plumpness (9,17). Delayed planting decreases barley grain yield and kernel plumpness (12) while increasing grain protein (3,9,17). Insufficient N can reduce grain yield and quality below acceptable levels, while excessive N usually produces undesirable high protein levels (1,14).…”

Planting date (D) and N fertilizer have been shown to significantly increase spring malting barley (Hordeum vulgare L.) grain yield and protein when grown under dryland production systems where water is limiting. This study was conducted to determine D and N rate effects on grain yield, grain protein, kernel plumpness and yield components of spring malting barley grown under a production system that minimized crop water stress. Between 1984 and 1988, 'Klages' barley was planted at 2-wk intervals between 15 April and 19 May (expressed as days from 1 January) at Powell, WY on a Garland clay loam (fine, mixed, mesic, Typic Haplargid). Ammonium nitrate was applied at rates of 0, 67, 134, and 202 kg N ha-•. Early planting increased kernel weight 14% and kernel density 16% compared to late planting; spike density was not affected. Increasing N from 0 to 202 kg N ha-• increased spike density 39% and kernel density 63%; kernel weight was not affected. Grain yield decreased from 4.7 to 4.0 Mg ha-• with later planting date and increased from 3.4 to 4.9 Mg ha-• as N rate increased from 0 to 202 kg N ha-• [Grain yield (Mg ha-') = 6.92 -0.027(D) + 0.007(N); R 2 = 0.89**, significant at P = 0.01). Grain protein was unaffected by D and increased from 102 to 121 g kg-• as N rate increased from 0 to 202 kg N ha-• [Grain protein (g kg-') = 127 -0.194(D) +
