Formation of bull-producing groups of cows in Ayrshire breed using genomically evaluated candidates

Purpose: Assessment of the quality of the well-producing groups, the productivity of candidates for the first lactation, the possibility of using genomically estimated cows to increase the parameters of mothers of future bulls, to analyze the quality of the offspring of bulls of various origins.Materials and methods. Research was performed on the basis of breeding plants Karelia Megrega (1455 cows) and Ilinskoe (1200 cows). Analyzed the productivity of bob-producing groups isolated on trivials. 66 Genomically estimated flaws were delivered from Finland after calving for milk productivity for the first lactation with local peers. In assessing the quality of the offspring of producers of different origin, the productivity of 1441 of the daughter of imported bulls and 620 daughters of domestic bulls took place. The degree of differences was assessed by the results of biometric processing of indicators.Results. At the Ilyinskoye dairy farm, the milk yield for lactation of cows of the bull-producing group is 11977 kg of milk with a fat content of 4.33%, protein content of 3.22%. There are 11119 kg of milk at the Megrega farm, 4.42% and 3.23%, respectively. A significant number of individuals (14.7-19.8%) with a milk yield above 9,000 kg of milk, which are a source of replenishment of bull-producing groups, were identified at breeding farms among the first heifers. The possibility of forming and improving the quality of bull-producing groups of cows at the expense of their own livestock is noted, provided that the factors of feeding and keeping animals, increasing the fat content and protein content of milk are optimized.Comparison of productivity indicators of imported "genomic" cows with local peers gave mixed results. At the Ilyinskoye farm, "genomic" cows significantly outperformed subjects of conventional breeding in all indicators: milk yield by 796-903 kg of milk, fat content by 0.27%, protein content by 0.09-0.06%, fat production by 59.4-63.8 kg, protein production by 33.9-34.8 kg, live weight by more thanAt the Megrega farm, in terms of fat content and production, "genomic" individuals also significantly outperformed local peers, and in milk yield and protein content, the differences were unreliable. Genomic evaluation of animals and the involvement of "genomic" cows can contribute to the formation of better groups of mothers of future bulls, especially to solve the most urgent problem of increasing fat and protein milk.Conclusion. In the conditions of large dairy breeding complexes with the technology of loose maintenance, it is advisable to use a system for placing groups of bull mothers in comfortable conditions in special rooms, including individual service.

Long-run asymmetric association between FDI and productivity in Turkey

Incoming foreign direct investments (FDI) may enhance the productivity level of the host country by bringing new advanced technologies. On the other hand, the nexus of FDI and productivity, rather than being linear, might be nonlinear because the effect of increases and decreases in FDI on productivity may not be symmetric. In this sense, this study investigates the asymmetric relationship between FDI and productivity in Turkey by using two different productivity indicators (i.e., PROD1 and PROD2) and employing a Nonlinear ARDL approach. Our hypothesis claims there is an asymmetric association between FDI and productivity in the long run in Turkey. Nonlinear cointegration test findings indicate that selected variables are cointegrated. Hence, they move together in the long run. Our study uses aggregated data at the macro level to analyze the long-term asymmetric relationship between foreign direct investment and labor productivity in Turkey using the NARDL estimation technique. Concerning the estimation results, a long-run nonlinear relationship between incoming FDI and labor productivity was detected, and this finding remained valid across two models constructed by using two distinct labor productivity indicators. As a whole, our results are consistent with the ones found in the literature. Besides, for the first time in the literature, this study addresses the long-run asymmetric nexus between FDI and labor productivity by using macro-level data specific to Turkey and makes various policy recommendations.

Material incentives for innovative activity of enterprise personnel based on key productivity indicators of innovation

Development and implementation of innovation is one of the means of providing competitive advantages for a business in a market economy. Innovative activity of a company ought to be expedient from the economic viewpoint and result in reduction of costs and maximizing the profitability of the company’s activity in the long-term perspective. One of essential factors of economic effectiveness of innovation is innovation-active personnel able to generate ideas and quickly adapt to changes, willing and motivated to participate in implementing innovation strategy of the company’s development. Not all employees a priori possess such features, and therefore the company ought to develop and take measures to facilitate their innovative activity. The article introduces the method of material incentives for innovative activity of the personnel suggested by the authors. The method is based on adapting a well-known system of key productivity indicators to innovative activity of a company. Personnel of the company is divided into three categories of employees according to their roles in realization of the organization’s innovative policy, and the authors defined a set of four or five key productivity indicators of their activity for each category. The authors defined a range of quantitative interpretation of the achievable result for each indicator. They suggested a mechanism for calculating the total amount of the incentive bonus which takes into account key performance indicators coefficients of innovative productivity and their value, the size of the bonus wage fund for the employee, the employee’s affiliation to one of the personnel categories established, the number of rewarded employees and the frequency of premium payments. Implementation of the suggested mechanism will ensure objective assessment and reward for the contributions made by all the interested employees into innovative development of the company increasing effectiveness of the production.

The effect of a vegetation period on productivity, protein and oil percentage in grain of the collection soybean samples

The purpose of the current study was to identify the effect of the length of a vegetation period of the collection soybean samples on grain productivity and quality. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2018–2020. The climate is semi-arid with moderately hot summers. The soil is ordinary thick calcareous heavy loamy blackearth (chernozem). The forecrop was winter wheat. The objects of the study were collection soybean samples of the ARIGPR named after N.I. Vavilov. The study was carried out on 75 samples, including 52 middle early samples with 110-120 days of vegetation and 23 middle maturing samples (120-130 days of vegetation), differing in morphobiological and economically valuable traits. The analysis of a vegetation period, grain productivity and quality of the collection soybean samples has shown that in the southern part of the Rostov region the most variable trait was grain productivity (Cv = 22.5%). The less variable characteristics were protein percentage in grain (Cv = 3.8%), a vegetation period (Cv = 4.2%) and oil content in grain (Cv = 5.3%). There has been identified a positive effect of the length of a vegetation period of soybeans on grain productivity and oil content in grain for both groups of maturity, protein percentage in both groups of maturity having a negative dependence on a vegetation period. The study has shown that in the middle early group, the largest grain productivity was obtained with 117 and 118 days of vegetation, the highest protein percentage with 110 and 114 days of vegetation, and the largest oil content in grain with 118 and 120 days of vegetation. In the middle maturing group, the maximum productivity indicators were obtained for the samples with 126 and 130 days of vegetation, the maximum protein percentage with 122 days of vegetation and the maximum oil content in grain with 123 and 130 days of vegetation. The samples showing the maximum indicators will be included in further soybean breeding.

Clogging of crops and productivity of 5-field crop rotation against the background of different intensity of the main cultivation of chernozem soil

Formulation of the problem. Crop rotations of modern field agriculture should be developed according to the principle of classical fruit change, which is an important factor in the high productivity of individual crops on different agro-backgrounds, which can be different ways of the depth of the main tillage. Verification of the latter was the main task of our research. Conditions and methodology. Field studies were carried out in a stationary experiment on podzolized chernozem with a 5-field crop rotation with such an alternation of spring crops: soybeans – rapeseed – wheat – oil flax – barley. The experiment compared the effect of plowing and flat-cut loosening at 15–17, 20–22 and 25–27 cm on the weediness of crops, crop yield and the productivity of crop rotation in terms of the yield of feed units and assimilated protein. Research results. It has been established that a significant part of weed seeds after flat-cutting loosening is concentrated in a layer of 0–10 cm, from where, under favorable moisture conditions, it can germinate with the formation of seedlings, which can bloom before cold weather and replenish the stock of weed seeds in the soil. During moldboard plowing, weed seeds are evenly distributed over the entire arable layer, as a result of which it can be half as much in the 0-10 cm layer as after non-moldboard plowing. Therefore, the actual weediness of crops cultivated in crop rotation has always been higher after flat-cutting loosening: soybeans – by 22.1 %, rapeseed – by 72.6 %, and wheat, oil flax and barley – 15.0, respectively; 20.4 and 20.3%. On average for the crop rotation, this increase averaged 25.2 % over three years. A decrease in the depth of cultivation also caused contamination of crops, and its deepening as a whole in the crop rotation had a positive effect on the cleanliness of crops from weeds. The level of weediness of crops of cultivated crops at the beginning of the growing season should be considered a determining factor in the formation of the productivity of these crops due to the presence of a strong and very strong correlation between these indicators. Wheat was the most productive in terms of the yield of feed units, and soy was the most productive in terms of the yield of digestible protein. This applied to both methods or techniques of the main processing, and individual crops against the background of plowing had an advantage in both productivity indicators over flat-cut loosening. The productivity of crops and crop rotation was higher against the background of deep cultivation compared to medium and shallow cultivation. Conclusions. The use of flat-cut loosening instead of moldboard plowing, as well as a decrease in the depth of both methods of processing, is accompanied by a significant increase in the contamination of crops. As well as a decrease in the yield of the main products and a noticeable decrease in the productivity of a 5-field crop rotation in terms of the yield of feed units and assimilated protein.

Productivity indicators and correlations between them in spring barley cultivars of Uman National University of Horticulture

The study of crop formation processes by constituent elements revealed the dependence of the parameters of the number of grains in the ear and the weight of barley grain at the same level of grain yield on the number of productive stems per unit area. It is established that the increase in the number of productive shoots per 1 m2 is accompanied by a significant decrease in the productivity potential of the ear in terms of the number of grains and the parameters of the mass of one grain. The correlation dependence of these yield elements on the stem density of barley is strong. In the studies of 2018–2021, the number of productive stems, plant height, productivity of one ear and weight of 1000 grains of spring barley varieties Daniele, Gezine, Beatrix, Soldo, 5/18, Fabiola, Sangria, Utah, 9/19, Mompi 19, Lyuba and Champush. Correlation holidays between these indicators were also established. The number of productive stems of spring barley varieties on average for 2018–2021 amounted to 0.87–1.39 pieces/1 plant. The average biotype ranged from 0.89 in 2018 to 1.47 in 2021. There was a medium and strong variation in the number of productive stems depending on genotypes. In most collection specimens, the rate varied greatly depending on growing conditions. Collectible samples 5/18 is a semi-dwarf, other biotypes are dwarfs. The highest plants were in 2020. The plant height of most cultivars varied slightly over the years of research. The average productivity of one ear of the analyzed collection samples was 0.63–1.17 g. The lowest indicators were noted in 2018, the highest – in 2020. The average weight of 1000 grains was 45.2–53.5 g with the highest indicator in 2021 g. The correlation between plant height and ear weight per ear was positive medium and close; between the number of productive stems and plant height – positive average, weak and negative average; between the number of productive stems and the mass of grain from the ear – a weak positive and negative correlation; between the number of productive stems and the mass of 1000 grains – the average positive and weak negative; between the height of the plants and the mass of 1000 grains and between the mass of grains from the ear and the mass of 1000 grains – from the average positive to the average negative.

Assessment of precursors and terms of tillage for soybeans by plant productivity in the Amur region

Soybean cultivation is the basis of agriculture in the Amur region. The area of soybean sowing is more than 74%, which leads to repeated sowing of soybeans and does not allow to fully realize the potential of cultivated varieties. The choice of predecessors and terms of tillage will increase the efficiency of soybean production in the region. The article presents the results of field ex-periments in the production conditions of agricultural enterprises of the Amur region. Plowing of perennial grasses in the first decade of July provides the highest yield of soybeans sown after perennial grasses. 24% more than plow-ing in the first decade of August. The tillage after perennial grasses to a depth of 12-14 cm with the BDM-8 discator and to a depth of 14-16 cm with the Morris cultivator can increase soybean yields by 39 and 22%, respectively. The choice of wheat as a precursor will improve productivity indicators and achieve yields greater than when cultivated in repeated crops by 25% and by 15% for the steam predecessor. Non-moldboard loosening of the soil after wheat to a depth of 14-16 cm at the end of April contributes to an increase in the productivity of soybean plants by 17.3% more than non-moldboard loos-ening at the end of May.

Evaluation of the Effectiveness of the Fungicide Comissar Against Rice Pyricularia

The results of research on the effectiveness of the fungicide Comissar are presented, EC (active agents propiconazole, 300 g/l and tebuconazole, 200 g/l) against rice Pyricularia, in the conditions of laboratory and vegetation experiments. The experiment was conducted in 2016-2017 in the Primorsky Territory. The fungicide was used at the consumption rate of 0.3 l/ha and 0.4 l/ha one time. In the primary laboratory tests on pure culture Pyricularia oryzae a high inhibitory activity of the drug against the coastal population of rice Pyricularia was revealed. It is noticed that Comissar significantly inhibits the growth of fungal colonies in all tested concentrations. Treatment of the nutriculture medium with solutions of the drug provides a significant preventive effect on the development of P. oryzae compared to an untreated control. The effectiveness of the drug was 100% on the 7th day and 89.3-90.4% on the 14th day. It was found that the use of the drug as a fungicide for the treatment of vegetative rice plants significantly reduces the development of Pyricularia. Comissar has a high biological efficacy against the pathogen at 47.4% (0.3 l/ha) and 62.7% (0.4 l/ha). The use of the fungicide contributed to the active growth of plants and it increased the main productivity indicators: the length of the panicle by 2.08-32.17 cm, the number of filled grains by 3.0-4.5 pcs. and their mass by 0.21-0.24 g per plant, as well as the mass of 1000 grains by 4.91-5.51 g. The maximum reliable increase in grain yield by 3.77 g/vessel was obtained in the variant using a fungicide at the minimum consumption rate.

On Labor Productivity in OECD Countries: Panel Data Modeling

Labor productivity is a key measure of economic performance and an essential factor of improving the living standards. High labor productivity growth rate can reflect increased use of capital, and/or a decrease in the employment of low-productivity workers. Thus, it can be said that labor productivity indicators reflect the effectiveness of labor utilization, labor cost, and revenue accumulation. This paper studies the impact of labor market conditions, economic integration, market size, and institutional quality on labor productivity in Organization for Economic Co-operation and Development (OECD) countries during the period from 2005 to 2017 by using panel data technique. The study finds that the random effects panel data model is the appropriate model to fit this data. The results suggest that average annual hours worked, labor force participation rate, and inflation rate have a negative significant impact on labor productivity in OECD countries. However, annual growth rate of GDP per capita, value added of industry, and control of corruption have a positive significant impact on labor productivity.

Evaluation of the original forms of tomato for heterosis breeding

The aim of this work is to study tomato sorters with contrasting complementary in hybridization of morpho-biological properties favorable for the expression of the effect of heterosis. Novelty. Tomatoes as a culture are quite plastic and easily adapted to the most diverse soil-climatic conditions of cultivation. Detectable natural mutations were easily fixed by screenings and gave rise to new and new forms. These changes concerned many signs and properties and allowed practically to design tomato plants for specific human needs. Methods. The studies included stamp varieties: Shtambovyy 5 and Fonarik, medium-ripe Kuban 557 and medium late-ripe Volgogradskiy 5/95 and Krasnodarets 87. The test was carried out in comparison with the best districted varieties (standards) in irrigated conditions. Results. By the nature of growth, the greatest habitus was observed in the parent line LS 2/11 164.6, which is a consequence of the subsequent orders of branching and the inflorescences formed on them, providing the highest yield of this line. According to the analysis of interactions, the year and genotype for the conditions of the year strongly determine the mass of fruits from one plant (66.1 %), while the number of fruits and the average weight of the fruit are determined mainly by the genotype: 92.8 and 73.2 %, respectively. The number and size of fruits are signs with strong genetic determinancy, which are components of the mass of fruits, which shows a strong dependence of the latter indicator on the conditions of the year. When combining optimal productivity indicators, they also showed the least variability, which is of considerable practical interest.
