Adequate Sampling

The identification of the suitable sample size and adequate sampling place when alfalfa hay was chemically analyzed in order to determine its nutritional value was the aim of our test. Two loads of alfalfa hay were used for collecting samples, two sizes each (15 and 10 subsamples, variant I and II, respectively). The crude protein content was determined using AOAC protocol. By assessing the statistic parameters of the crude protein content of the forage, function of the sampling place and sample size, we observed the influence of the sampling technique on the accuracy of the determinations. The highest coefficient of variability was recorded when samples were collected from the base of the load in each case. Only the crude protein content differences between the samples collected from the other parts of the load and base of the load (variant I, in both loads) were statistically significant (p < 0.05). Within the same load, no significant differences (p > 0.05) were recorded. Even notable differences were not obtained in crude protein content determination function of sampling place or sampling size, the need and care in sampling should be considered.

The University

In a spring wheat breeding nursery at the University of Manitoba in 1967, the wheat protein content of systematic control plots of Triticum aestivum cv. Manitou varied from 10.3% to 16.5% (at 13.5% moisture basis). The correlation between grain yield and protein content of these plots was 0.88 and significant at the 99% confidence level. Correlations calculated for control plots at specified distances apart indicate that for all breadmaking quality test characteristics except bushel weight and flour yield, contiguous plots are significantly more similar in quality than those further apart. The correlation between control plots 2.7 m (9 ft) apart is 0.84 (P = 0.05) for wheat protein percent and of similar order for those quality characteristics which are dependent on total protein. Areas of high and low quality "potential" can be identified in a wheat nursery by using quality data from controls at frequent intervals, and this information should be used by the breeder when assessing the single quality test of a breeding line from a given area of the nursery.

Field studies were conducted during the years 1957 to 1962 inclusive to measure and delineate factors which cause the protein variations encountered in summerfallow wheat crops in Saskatchewan. Differences in protein content of wheat of over 7% were found between different sampling topographical positions within any one field. Fertilization with nitrogen and phosphate at recommended field rates did not alter the protein content of the grain even though increases in yield of up to 100% were measured. Data are presented which indicate that much of the variation in protein values of wheat within fields can be attributed to changes in the type of soil profile and the associated microclimate.

Ha Protein

Protein content and yield of wheat usually increased with increases in the amount of nitrate nitrogen present in the soil. Large yield increases were obtained when 34 or 67 kg N/ha was applied broadcast to nonfallow land at time of seeding, but protein content decreased or increased only slightly. Protein content increased substantially when 101–202 kg N/ha was applied to nonfallow land, whereas yields were not increased above that obtained with 67 kg N/ha. Protein content of wheat grown on fallow land increased with increasing amounts of added nitrogen up to about 134 kg N/ha; yields did not increase greatly with added nitrogen. Wheat protein content was found to be related to nitrogen supply. An R2 value of 0.78 was obtained when wheat protein content was related to soil nitrate nitrogen measured to a depth of 61 cm and nitrogen applied broadcast at time of seeding. Soil- and foliar-applied postemergent nitrogen applications increased the protein content more than equivalent rates of nitrogen-applied broadcast at time of seeding in field studies conducted during 1971, but not in 1970. A greenhouse experiment showed that usually less than 1% of the nitrogen from ammonium nitrate, urea, or ammonium sulfate was absorbed into the grain when applied to the foliar surfaces of wheat; usually greater than 30% of the nitrogen from these fertilizers was absorbed when soil applied.

Wheat Protein

Sprinkler irrigation on clay soils in southern Finland decreased the protein content of spring wheat flour in five field experiments in the years 1967—70, by 16 ± 4 per cent on an average. The amino acid composition, however, was improved, because the proportion of lysine was increased by 6 ± 4 %. Accordingly, the content of lysine in flour was decreased by irrigation only by 10 ± 5 %. An increase of fertilizer nitrogen from 68 to 144 kg/ha increased the protein content of wheat flour by 19 ± 5 %, but the proportion of lysine in the amino acid composition decreased by 9 ± 4 %. Therefore, the lysine content in flour was increased by nitrogen fertilization only by 8 ± 5 %. It seemed as if urea and ammonium nitrate limestone would have had about the same effect on the quantity and quality of wheat protein. As a consequence of the reversed influences of irrigation and nitrogen fertilization on the wheat protein it was possible, by means of irrigation and an additional nitrogen fertilization, to produce 65 per cent higher grain yields without any noteworthy changes in the contents of protein or amino acids.
