The estimation of Raushan variety of barley and the new Kamazhevsky variety, which was regionalized in Tatarstan in 2017, is given. The experiment revealed the influence of weather conditions and varieties during the years of research (2015-2017), on the formation of grain productivity, the content of total nitrogen in the aboveground mass of plants, the accumulation of protein in grain and gross harvest of protein per hectare. It is noted that the productivity for different years are different, the highest yields of grain of Raushan and Kamashevsky varieties were obtained in 2017 - 4.62 and 5.21 tons per hectare, respectively, when the hydrothermal coefficient was 1.3 units. In comparison with 2015 the productivity of Raushan variety was higher to 1.89 tons per hectare and to 1.69 tons per hectare in 2016. The same pattern was also found in Kamashevsky variety, 1.64 and 1.52 tons per hectare, respectively. The average productivity of Raushan variety for 3 years was 3.43 tons per hectare, less to 0.73 tons per hectare than Kamashevsky. The highest nitrogen content (close to the optimum 4.7-5.1%) in the aboveground mass was found in 2016 in plants of Raushan variety of 4.3%, Kamashevsky variety 4.0%, whereas in 2017 - 2.89% and 3.32%, respectively. The nitrogen content in dry years is higher in the aboveground mass of the Raushan variety, beginning with the tillering phase - 4.3%, Kamashevsky variety - 4.0%. It was revealed that the maximum content of protein in grain grade Kamashevsky accumulate in arid 2015-2016 years - 13.84%, more by 0.95% than the Raushan variety. In 2017 the protein content in the grain was formed at the same level Raushan 11.77%, Kamashevsky 11.07%. Evaluation of varieties on the gross harvest of protein per hectare, shows that the Kamashevsky variety forms on average 5.37 tons per hectare of protein over 3 years, more than Raushan grade by 1.08 tons per hectare.

Abstract Currently, the reference procedure for determination of the "protein" content of milk is based on measurement of the total nitrogen content of milk by the Kjeldahl method (AOAC method, 920.105). About 6% of the total nitrogen content of milk Is nonprotein nitrogen. Therefore, total nitrogen multiplied by the conversion factor 6.38 overestimates the true protein content of milk on average by about 6%. In the present study, new direct and Indirect methods were developed for measurement of the true protein content of whole milk by Kjeldahl nitrogen determination. Both new methods are sample preparation procedures used to fractionate the nitrogen-containing compounds In milk prior to measurement of the nitrogen content of these fractions by Kjeldahl analysis. The collaborative study consisted of 9 pairs of blind duplicate milk samples that were analyzed for total nitrogen, nonprotein nitrogen, and protein nitrogen by each of 10 laboratories. Both methods for true protein measurement (direct and Indirect) gave acceptable statistical performance characteristics and good agreement between methods. The new direct method requires about half the laboratory analysis work of the indirect method (i.e., total minus nonprotein nitrogen). The methods have been adopted official first action by AOAC as (1) a new method for nonprotein nitrogen determination in milk, (2) a new method (direct) for determination of protein nitrogen content of milk, and {3) an alternative method (indirect) for determination of protein nitrogen content of milk.

Nonprotein nitrogen (NPN) content in largemouth bass accounted for 9% of the total nitrogen content. This level was influenced by feeding level and probably body weight. A consideration for NPN is essential for quantitative protein estimates.

Breeding and selection of winter pea for seed quality is a serious challenge to every breeder. The result of breeding mainly depends on good knowledge of the genetic material. Chemical and technological analysis is necessary for an accurate determination of the following traits of technologically mature seed of the winter pea collection: protein content, total nitrogen content, total sugars content, starch content, fatty oil content, cellulose content, and ash content (g (100 g)-1). The protein content in the tested lines of pea was in the range 22.86?28.04 g (100 g)-1, the total nitrogen content 3.66?4.49 g (100 g)-1, total sugars content 10.30?14.67 g (100 g)-1, starch content 39.44?46.23 g (100 g)-1, fatty oil content 1.48?1.89 g (100 g)-1, cellulose content 8.79?10.28 g (100 g)-1 and ash content 3.08?3.67 g (100 g)-1. PCA analysis was used to identify the three components that collectively explained 81.59 % of the total variation. The first component was mainly defined by the ash and the total nitrogen, protein and cellulose contents. The second one, independent from the first one, was mainly correlated to the fatty oil and starch contents, while the third was defined by the content of total sugars.

This paper presents researches regarding the influence of organic (sheep manure) and NPK mineral fertilizers on the soil parameters and total crude protein content (%) of forages, harvested in the middle of May, 2008, from a permanent meadow situated near Grădinari, in Caraş-Severin district. The studied permanent meadow was organized in ten trials fertilized with different doses of NPK mineral fertilizers, organic (sheep manure) and organic-mineral fertilizers. For each trial was made five replications. The total nitrogen content (%) was determinated by Kjeldahl method, and total crude protein was calculated by multiplying total nitrogen content with 6.25. The soil pH was determinated in aqueous solution (ratio soil / water = 1/10) using potentiometric method. Mobile forms of potassium and phosphorus were determinated by Egner-Riehm-Domingo method, extracted from soil with an acetate-lactate solution buffered at pH= 4.6, at 1/5 soil-solution ratio. The statistical interpretation was performed with Multivariate Exploratory Techniques, Cluster Analysis, implemented in Statistica 6 software. Using Cluster Analysis is possible to show the influence of organic and mineral fertilizers on the soil parameters (pH, total nitrogen content, mobile form of P, and mobile form of K) and total crude protein content of forages from the permanent meadow from Gradinari (Caraş-Severin District) by grouping all ten experimental trials in three main groups.

In the field experiments with brewing barley, carried out on sod-podzolic medium-loamy soil, it has been found out, that the raising doses of nitrogen application increased grain productivity of barley plants (by 18-33%), grains protein content, α-amylases, сatalases and peroxidases activity, but decreased grain unit and β-amylases activity. In water deficit weather conditions (Hydrothermal coefficient of moisture on the G.T Selyaninov = 1-1.3) the raising doses of phosphorus and potassium (Р120, К120) increased the grain productivity of barley plants (by10-28%), the mass of 1000 grains, their germination ability and α-amylases activity, but decreased β-amylases, сatalases, peroxidases activity and grains protein content making it not more then normative level (12%). In 7-days germinated grains of barley harvested in the variants with raising doses of nitrogen it has been revealed increasing of α-amylases, proteases, catalases, peroxidases activity, but decreasing of β-amylases activity. In the variants with higher doses of phosphorus and potassium barley grains were formed, which observed on the 7th day of sprouting increased α-amylases and peroxidases activity and reduced activity of β-amylases. It has been revealed, that phytoregulators novosil and epin application enhanced grain productivity of barley plants (by 6-14%) and α-amylases activity in grains, but decreased β-amylases activity. In water deficit weather conditions novosil phytoregulator reduced grains protein content to normative level. In the variants with epin phytoregulators application barley grains were formed in which germination increased amylase and peroxidase activity, improving their ability to malting.
