Field experiments with three barley (Hordeum vulgare L.) cultivars, Olli, Bonanza and Klages, were conducted for 3 yr at Beaverlodge, Alberta to determine the effect of harvest time and drying method on yield and quality. Plots were harvested at 5% kernel moisture content (KMC) intervals in the range of 45–15% and dried in the windrow or artificially dried. Yield, test weight, 1000-kernel weight, germination percent, protein content, phosphorous content and commercial grade were determined. Protein and phosphorous content were unaffected by the treatments. Windrowing at 40% KMC or less had little effect on yield or quality characteristics while threshing and artificially drying barley above 20% KMC reduced test weight and germination. Windrowing reduced yields of Olli and Klages barley by up to 19% compared to direct combining. Most treatments received feed grades, but the crop was most likely to meet Canada Western grades when windrowed at 30% KMC or less under favourable harvest conditions.Key words: Hordeum vulgare L., kernel moisture content, yield, quality

Effect On Yield

Barley (Hordeum vulgare L. ’Bonanza’) was windrowed for five harvesting seasons at kernel moisture contents (KMC) (throughout this paper, wet-basis moisture content is used) ranging from about 55 to 19% at Melfort in the Parkbelt area of Saskatchewan. Windrowing the crop at 40% KMC did not cause a significant loss in grain yield or quality as measured by test weight, 1000-kernel weight, percent protein and phosphorus content as compared to harvesting at lower KMC. The results show that windrowing barley at 30–40% KMC will often reduce shattering and facilitate earlier combining. These results agree with earlier work reported.Key words: Hordeum vulgare L., harvesting, kernel moisture content, yield, quality

Field experiments with the oat (Avena sativa L.) cultivars Random Harmon and Kelsey were conducted for 3 yrs at Swift Current, Saskatchewan, for 2 yr at Saskatoon, Saskatchewan, and for 3 yr with cultivars Random, Cascade and Athabasca at Beaverlodge, Alberta. Plots were harvested at kernel moisture contents (KMC) in the range of 15–45%. At Swift Current and Beaverlodge, material was dried in the field (windrowed) or artificially dried in a forced-air oven at 50 °C after threshing; all Saskatoon material was field-dried. Test weight, 1000-kernel weight, grain protein-N and commercial grade were determined. Grain protein-N was not affected by cutting time or drying method. Test weight of both windrowed and artificially dried material tended to increase as harvest was delayed until lower KMC values were reached. One-thousand-kernel weight was less affected by harvest KMC, but did increase as harvest was delayed until 35% KMC in some situations. Material cut at high KMC at Swift Current and Saskatoon was downgraded due to high proportions of green kernels, and in some instances, due to low test weight. The proportion of green kernels tended to be greater in the artificially dried than in the windrowed material at high harvest KMC values. The no.1 CW grade was not reached unless harvest was delayed until KMC was less than 20%, provided that there was no secondary tillering. Mildew and staining were major grading factors at Beaverlodge during 2 yr. particularly in the windrowed treatments. Grades tended to be higher in artificially dried material when rain occurred during the harvest period. Intrapanicle differences in maturation, which produce the varying proportions of green and mature kernels, were demonstrated in excised panicles using eosin dye and 14C-sucrose.

The effect of sowing rate (10-110 kg/ha) on the grain yield of barley (Hordeum vulgare L.) was determined from a total of 20 field experiments conducted in northern New South Wales from 1983 to 1986. Effects of sowing rate on kernel weight and grain protein percentage were also determined from 12 experiments conducted in 1985 and 1986. Two barley varieties were tested each year. In all years fallow plus winter rainfall was equal to or greater than average. Grain yield increased with higher sowing rates in most experiments, with the response curve reaching a plateau above 60-70 kg/ha. For 13 of the 40 variety x year combinations, grain yield fell at the highest sowing rates. Only in an experiment where lodging increased substantially with higher sowing rates was there a reduction in yield at a sowing rate of 60 kg/ha. The average sowing rate for which 5 kg grain was produced per kg of seed sown was 63 kg/ha. Grain protein percentage usually fell, and kernel weight invariably fell, with increasing sowing rate. Increasing sowing rates from the normal commercial rate of 35 kg/ha to a rate of 60 kg/ha typically increased grain yields by 100-400 kg/ha, decreased kernel weight by 0.4-2.0 mg, and decreased grain protein by up to 0.5 percentage points. In no case was the grain weight reduced to below malting specifications. It was concluded that sowing rates for barley in northern New South Wales should be increased to about 60 kg/ha.

Two spring triticale (X-Triticosecale Wittmack) cultivars, Carman and Welsh, and one advanced-generation breeding line were grown under field conditions for 3 yr to study the effects of harvest time and drying method on quality and grade. Plots were harvested at six to seven intervals when kernel water concentration was in the 1000 to 100 g water per kilogram kernel dry weight range. Grain was dried in the field in simulated windrows or artificially dried in a forced-air oven at 40–45 °C. Test weight, 1000-kernel weight, falling number, germination, and commercial grade were determined. Test weight increased with decreasing kernel water concentration at harvest, particularly in the artificially dried treatment. Test weight was greater in the windrowed than in the artificially dried treatment, especially for harvests made at high water concentrations. Harvest at high kernel water concentrations tended to reduce 1000-kernel weight, more so in the windrowed than in the artificially dried treatment. Although falling numbers were influenced by harvest time and drying method, there were no clear trends. Germination was reduced in material cut at a kernel water concentration above 680 g∙kg−1 in 1 of 2 years. Grades were reduced by artificial drying of grain, particularly when harvested at high kernel water concentrations. Grades were unaffected by windrowing at kernel water concentrations of up to 1000 g∙kg−1.Key words: X-Triticosecale Wittmack, test weight, falling number, germination, windrow

Yield Test

A study was initiated in 1990 to determine the genetic variation and adaptation of all registered Canadian barley (Hordeum vulgare L.) cultivars. Seventy-six cultivars were tested at four locations across Canada (Charlottetown, Ottawa, Brandon, and Bentley) in 1991 and 1992. These cultivars were grouped into 10 classes and classes were compared in five categories: eastern vs. western, doubled-haploid (DH) vs. conventional, feed vs. malting, two-row vs. six-row, and hulless vs. covered. These 76 cultivars showed remarkable variation in yield, test weight, kernel weight, plant height, and maturity and responded differently to the environments. Among them, Albany and Chapais had the highest yield and they also yielded well in both Eastern and Western Canada. Thus, some barley cultivars were widely adapted across the whole country. Two-row cultivars had higher test weight and higher kernel weight than six-row and appeared to be more stable in yield over the environments. Eastern two-row cultivars were superior in yield, test weight, and kernel weight than western two-row. Eastern two-row, in general, performed well across Canada. Several western six-row cultivars performed well in both Western and Eastern Canada. Therefore, greater exchanges of breeding materials between the two regions are recommended in order to fully exploit the genetic potentials of new cultivars. DH cultivars yielded as well as conventional cultivars and responded similarly to the environments. This substantiates that complete homozygosity and homogeneity have very little effect on the performance of DH cultivars. Among the western two-row, feed cultivars yielded either higher than or the same as malting cultivars in the eight environments. Hulless cultivars had lower yield, higher test weight and lower kernel weight than covered cultivars. Key words: Barley, Hordeum vulgare, cultivar, yield, adaptation

Hard Red Spring Wheat

Two hard red spring wheat (Triticum aestivum L.) cultivars, Neepawa and Columbus, were harvested at 5% kernel moisture content (KMC) intervals from 45% to 15% for three growing seasons. Two drying treatments, field drying in windrows and oven drying were evaluated. Yield, test weight, 1000-kernel weight, protein-N, falling number and commercial grade were determined. Protein-N and 1000-kernel weight were reduced when the crop was harvested above 40% and 35% KMC, respectively, but were not affected by drying method. Yield losses up to 12% were recorded with windrowing. Windrowing at 35% KMC or less in warm, dry conditions had little effect on test weight, falling numbers, and grade. Under wet conditions, windrowing above 20% KMC resulted in lower falling numbers and a loss of grade. Direct combining and artificial drying above 20% KMC lowered test weights, falling numbers and grade. The current recommendation of windrowing at 35% KMC is supported under good harvest conditions but either windrowing or straight combining at 20% KMC would be superior under damp harvest conditions.Key words: Triticum aestivum L., kernel moisture content, drying method, falling number, quality, grade

A.Trof.: one coeleste (L.) A.Trof.) from 26 countries, 11 years and four places of reproduction was analyzed. Seeds with 5–8% moisture content were stored in chamber with unregulated and 4oC temperature. The possibility of seed storage under these conditions for at least 10 years without significant changes in germination has been established. The importance of meteorological conditions in the formation and ripening of seeds for their longevity is confirmed. The relationship between the decrease of barley seeds longevity and storage conditions, amount of rainfall, temperature regime during the growing season of plants is discussed.

Grain quality, timeliness of harvest, and profitability can be increased by improving field drying characteristics of maize (Zea mays L.) hybrids. To better understand hows genes control ear drying, I compared maize strains developed by divergently selecting three cycles for (1) high HM or low LM moisture content at 45 d post pollination in the field or (2) fast FD vs. slow ear drying SD In laboratory. A field study across five locations compared HM, LM, FD, and SD strains from each of five synthetics for grain yield, ear moisture at harvest, test weight, lodging, and other agronomic traits. I studied ear moisture during grain filling for two subsets of divergently selected strains from one and three synthetics for 2 yr. In a third 2-yr field study, I measured mature kernel weight, lag period duration (LPD), effective grain-filling period (EFPD), and rate of dry matter accumulation (RDMA) for LM and HM strains developed from each of four synthetics. When averaged across the five synthetics, both SD and LM selections produced equivalent yields but lower ear moisture at harvest than the corresponding divergent strains. The LM strains had higher test weights than HM strains. When averaged across three synthetics and 2 yr, the HM strains produced higher moisture than LM strains at 15, 30, 45, and 60 d after silking. However, environments also influenced moisture content of the kernels during grain filling. In three of the four synthetics studied, HM strains had heavier kernels than corresponding LM strains. The heavier kernels seem to be due to increased RDMA. When averaged across four synthetics, LM strains had shorter LPD than HM strains. These correlated selection responses suggest that a genetic association exists among moisture content during grain filling, moisture content at physiological maturity, moisture content at harvest, LPD, and test weight. Breeding for LM or SD should improve field-drying characteristics of maize without increasing stalk breakage or decreasing yields.
