The gherkin (Cucumis anguria L.) is a vegetable widely adapted to different edaphoclimatic conditions. It can be used for human consumption, being an alternative healthy nutrition source in the increasing world population. This study aimed to evaluate the yield, content of soluble solids, potassium and leaf sulfur accumulation, and the chlorophyll content of the gherkin cultivar 'Nordestino' under different sources and doses of potassium fertilizer. The experiment was carried out in a complete randomized block design, with treatments distributed in a 6 x 2 factorial scheme, with six doses (0, 50, 100, 150, 200, and 250 kg ha-¹) and two sources of K2O (potassium chloride and sulfate), in four replicates. The highest soluble solids content (3.68%) was obtained under the dose of 78.75 kg ha-¹ of K2O with potassium sulfate. The maximum dose of K2O resulted in a tissue K content of 20.7 g kg-¹, with a tissue S content of 4.49 and 3.24 g kg-¹ under the doses of 250 and 164.16 kg ha-¹ of K2O, respectively, using sulfate and potassium chloride as K source. The total yield was 7.78 t ha-1 and 6.92 t ha-1 under the doses of 102.25 and 81.75 kg ha-¹ of K2O, respectively, using sulfate and potassium chloride as sources. Based on this study, the dose of 105.45 kg ha-¹ of K2O using potassium sulfate as K source is recommended to reach the maximum productivity of the gherkin cultivar 'Nordestino'.
Comparative study of two annual Medicago species: Cytogenetical approaches and seed storage proteins analysis in M. polymorpha L. and M. laciniata (L.) Mill.
Authors: Fairouz Lacheheb , Moulay Belkhodja
Published: February 2025

Species of the Medicago genus are of great interest for their ability to fix atmospheric nitrogen. Only a few species, mainly those used in agriculture, have been well studied. There is a particular lack of study of the annual wild species, which are represented in very small numbers (4/103) in the genus. This is why we have chosen to study two annual species with two different basic chromosome numbers, Medicago laciniata (L.) Mill. x = 8 and Medicago polymorpha L. x = 7. The main questions were to understand how the decrease in basic chromosome number from x=8 to x=7 occurred and what is the relationship between these species. To answer these questions, the karyotype was analysed using conventional karyological methods and the genome size was assessed using flow cytometry. Ten accessions of M. polymorpha and six of M. Laciniata were studied for cytogenetical feature (by classical karyological methods). Apart from the basic chromosome number, some differences in karyotype features such as chromosome size and morphology were observed. The mean genome size values were 2C = 1.817 pg for M. Laciniata and2C=1.123 pg for M. polymorpha. The SDS-PAGE gel analysis of the seed storage proteins showed species-specific polypeptides pattern. In addition to differences in the basic chromosomes number, karyotype characteristics and total nuclear DNA content, protein profiles also differ between the two species. We suggest that decrease in basic chromosome number from x=8 to x=7 is probably due to occurrence of Robertsonian fusion or centric fusion.

Introduction. This study examines the goal- and situation-related determination of human behavior. The concept of the contextual nature of human goals was the basis of research. According to this principle, goals should be considered (1) in a broad life context of opportunities given to individuals by life circumstances, or in terms of limitations related to them; (2) in a time context of individuals’ life plans, future, ideas and their success or failure in achieving their goals. Methods. A questionnaire form was created in which hypothetically assumed goal setting factors (importance of goals in different spheres of life and satisfaction with their implementation, assessment of the opportunities provided by the situation, etc.) were recorded. Furthermore, the Potential for Self-change questionnaire (V. R. Manukyan, I. R. Murtazina, & N. V. Grishina), the Test of Existential Motivations (A. Längle), and the Zimbardo Time Perspective Inventory (F. Zimbardo) were used. The sample comprised 350 subjects; 84.8 % of respondents aged 17 to 25. Correlation and factor analyses were performed. Results. The importance of individual goals was related to the assessment of the possibilities of achieving them in the current life situation, satisfaction with their implementation in major spheres of life, compatibility between achievements and expectations of the past, and willingness to self-change and to change life situation. The major goal setting factor, referred to the ‘window of opportunities’, integrates an individual’s assessment of the extent to which his/her current life situation in various spheres enables him/her to realize himself/herself and his/her capabilities. The ‘window of opportunities’ is also characterized by significant associations with the need for self-change, the ability to consciously change the self, the belief in the possibility of changing the self, and fundamental existential motivation aimed at meanings in life. Discussion. The results of this study confirm the appropriateness and necessity of context-based studies of human life goals and the heuristic value of this approach.

Introduction. The solution to the problem of the relationship between self-assessments of appearance and assessments of subjective well-being (SWB) can answer the question of the direction in which these phenomena are determined by each other. The research results show the need to consider factors that change the structure of the relationship between self-assessments of appearance and assessments of subjective well-being. This study is the first effort to identify the types of structures of relationships between self-assessments of appearance and assessments of subjective well-being when including such socio-demographic characteristics as gender, age group, level of education, and economic status. Hypothesis: The types of relationships between self-assessments of appearance and assessments of subjective well-being may differ depending on the impact of a combination of socio-demographic factors. Methods. The study used the Socio-demographic Questionnaire, the Self-assessments of Appearance questionnaire by V. A. Labunskaya (2019), and the Subjective Well-Being Scale modified by V. M. Sokolova (1996). Russian-language sample comprised of 163 subjects: (a) 64.5 % – 18–25 years old (mean age = 20.9); (b) 35.5 % – 26–36 years old (mean age = 31.4); 64.5 % of respondents were women; 52.2 % had incomplete higher education; 54.6 % considered themselves to be in the group of ‘rather poor than rich’. Mathematical procedures: frequency, correlation, and factor analyses, t-test for two independent samples (IBM SPPS Statistic 23.0). Results. Four types of relationships were identified. The strongest factor was the aggregate of self-assessments of appearance, associated with belonging to the age group of 26–36-year-olds and with the ‘rather rich than poor’ economic status. Discussion. First, self-assessments of appearance show varying sensitivity to socio-demographic factors and their combination. Secondly, self-assessments of appearance in combination with socio-demographic characteristics are a stronger factor of the direction of associations compared to SWB assessments. Thirdly, there is independence and autonomy of self-assessments of appearance and SWB assessments in young people with certain socio-demographic characteristics.

Introduction. To study the regularities of formation of individual experience we summarize the results of research in consolidation, reconsolidation of memory, extinction and forgetting within a unified idea that considers them in the frames of systems psychophysiology as manifestations of two coordinated processes: formation of new experience and modification of previously formed experience. Theoretical Justification. Within the framework of the theory of functional systems, it had been proposed that systemogenesis also takes place in adults, since the formation of a new behavioral act is the formation of a new system. In studies with single-neuron activity recording it was shown that during performance of new behavior the simultaneous activation of multiple earlier formed systems occurs along with activation of new systems formed during learning. Therefore, we consider consolidation, reconsolidation, extinction, and forgetting as manifestations of reorganization of individual experience as a whole. The results of research in the neurophysiology of memory show that the processes of memory formation (including its consolidation) and forgetting are not mutually exclusive and can take place independently. Some forms of forgetting are caused by the inability to use memory, rather than by its removal, that makes forgetting similar to the formation of extinction. Discussion. We argue that (re)consolidation, extinction and forgetting may be based on similar long-term changes in previously formed experience, in particular those that do not let some elements of this experience to be utilized further.

Introduction. The processes of information selection and memorisation undergo changes during ontogeny of the controlling functional systems of the brain, including the formation of inhibitory control associated with the organisation of proactive interference. The aim of the present study was to investigate the regularities of changes in the volume of memorisation of visually presented information at different stages of ontogeny (in the age range from 5 to 78 years) due to both the action of proactive interference and the activity of learning in the process of reproduction during testing. Methods. A total of 563 participants, including preschool and school-aged children, students, and retired people, took part in the study. To investigate inhibitory functions in memory processes, a computerised technique was used to study the memorisation of the same set of visual stimuli presented in different order in three series. A new series was started after the subject made an error in the previous series. Results. Nonlinear changes of proactive interference (RIF) during the reproduction of visual information in ontogeny were found: proactive interference is less pronounced at preschool age, reaches its maximum expression in students at the age of 20 years and remains at a high level in the elderly when the volume of reproduced material decreases. Comparison of proactive interference in people with different memory productivity revealed that the expression of proactive interference is higher at high productivity levels regardless of age and interference is insignificant in people with low memory productivity. Relationship of interference with gender was found only in preschool and junior high school age: proactive interference is higher in girls. possibly due to the speed of brain maturation in this age range in boys and girls. Discussion. It is shown that the critical period for the formation of proactive interference is the age range of 6-8 years, when the severity of interference depends on gender, which is probably due to the conditions of brain maturation in boys and girls. Proactive interference reaches its highest expression in students at the age of 20 and then gradually decreases in old age.

Introduction. In recent years, private investors have significantly increased their influence on the Russian securities market. Understanding the cognitive biases of private investors will help to fill the gap in research into cognitive decision biases in decision-making in investment behavior. Private investors participate in the placement of federal loan bonds and also support private enterprises through participation in corporate bonds. This study aims to test experimentally the impact of the framing effect (the effect of the ‘frame’ or information presentation format) on the decision-making of potential investors in securities trading. Methods. The sample comprised 20 adults aged 20–35 years (7 men and 13 women). Stimulus materials were presented on the Neurobureau platform for neurocognitive research and involved recording subjects’ videooculography using the GazePoint GP3 eye tracker (with the Neurobureau software). A total of 240 measurements were carried out. The experimental series consisted of 12 stimuli. Pairs of financial proposals were created, with differences provided only by different formulations and emotional and semantic features. Results. Using quantitative data analysis, significant differences were established between responses to stimuli of the same content but different wording. A step-by-step regression analysis confirmed the impact of the framing effect on economic decision-making. In qualitative data analysis, the proportion of attention to stimuli was determined using heat maps, which also confirmed the role of lexical forms and emotional connotations of the wording of company news (without changing objective information) in purchasing and selling shares or in not taking action. Discussion. The results of the experiment proved the impact of the framing effect on the decision-making of potential investors. Based on the obtained data, a conclusion is drawn on the importance of psychological factors in selecting and assessing information resources in the process of obtaining company news information.
Objetos de aprendizagem: uma ferramenta pedagógica no processo de ensino aprendizagem do conteúdo de estequiometria na disciplina química no ensino médio
Authors:   , Silva Lilianne de Sousa
Published: February 2025

A disciplina Química busca propiciar uma aprendizagem que garanta aos alunos condições de compreender e desenvolver a consciência plena de suas responsabilidades e direitos ao mesmo tempo que constroem os conhecimentos científicos inerentes à disciplina. Contudo, temos a impressão que o ensino desta disciplina é encarado pela maioria dos alunos como sendo distante da realidade em que estão inseridos e repleto de fórmulas e teorias a serem decoradas. É necessária a superação da prática docente centrada na memorização e reprodução de conceitos científicos. Nesse cenário, surgiu o interesse do presente estudo com o objetivo de avaliar o impacto do uso dos objetos de aprendizagem no desempenho dos alunos do Ensino Médio, no conteúdo de estequiometria, através de um estudo experimental. Este trabalho foi fundamentado teoricamente nos trabalhos e pesquisas de Carneiro e Silveira (2014), Tarouco e Dutra (2007), Santos e Silva (2014), Costa e Zorzi (2008), Silva (2015), Grisolía e Grisolía (2009), Staver e Lumpe (1995), Moran, Masetto e Behrens (2006), Oliveira (2013), Sabbatini (2012), Beck (2002), entre outros. Foi desenvolvida uma pesquisa de caráter experimental na qual coletamos dados quantitativos e qualitativos através da aplicação de uma escala de Likert e um teste (pré e pós) com alunos de duas turmas da 1ª série do Ensino Médio. A análise dos dados revelou que o uso dos objetos de aprendizagem facilita a compreensão de termos/conceitos teóricos e que por vezes não são possíveis de serem visualizados pelos alunos. Podemos afirmar que existe uma grande defasagem dos conteúdos matemáticos necessários para compreensão dos cálculos estequiométricos, fazendo assim necessária a realização de prática interdisciplinar que visem o desenvolvimento das habilidades lógico-matemáticas fundamentais para o conteúdo de Química. Com base nos resultados dos testes, para esse grupo em estudo, podemos concluir com certa segurança que a utilização dos objetos de aprendizagem para o ensino de estequiometria foi eficiente e eficaz auxiliando na construção da aprendizagem significativa. Observamos que os resultados vão de acordo com a nossa hipótese experimental, ou seja, o uso dos objetos de aprendizagem interfere positivamente no ensino-aprendizagem dos conteúdos de estequiometria. Assim, podemos considerar que é preciso capacitar o professor para fazer um uso mais efetivo dessa ferramenta em sala de aula, bem como contribuir para a construção da autonomia do educando no processo de ensino-aprendizagem

Published: February 2025

BACKGROUND

Eating is a fundamental daily activity essential for maintaining independence and quality of life. However, individuals with neuromuscular impairments often face significant challenges in achieving autonomous eating due to the limitations of existing assistive devices, which are largely passive and lack adaptive capabilities.

OBJECTIVE

This study introduces an advanced feeding robot designed to address these challenges by integrating time series decomposition, autoregressive integrated moving average (ARIMA), and feedforward neural networks (FFNN). The robot is aimed at enhancing feeding precision, efficiency, and personalization, ultimately promoting autonomy for users.

METHODS

The proposed feeding robot employs a combination of sensors and actuators to collect real-time data, including facial landmarks, mouth status (open/closed), fork-to-mouth and plate distances, and the force and angle required for food handling. ARIMA and FFNN algorithms analyze this data to adapt to users' unique eating patterns and preferences. Predictive modelling with ARIMA anticipates changes in user behavior, enabling dynamic adjustments to meal portions and feeding habits. A strain gauge sensor regulates pressure for stabbing or scooping, while ultrasonic sensors ensure precise positioning. Facial landmark detection and object recognition algorithms enhance safety by verifying open-mouth conditions and monitoring plate contents.

RESULTS

The integration of ARIMA and FFNN significantly improved feeding accuracy and personalization. The combined model achieved an〖 R〗^2 of 94%, outperforming standalone ARIMA (85%) and FFNN (88%). This fusion of algorithms enabled the robot to model temporal user interaction dynamics, leading to enhanced precision. The results demonstrated an adaptive response, with the robot achieving a high success rate and minimizing delays. The predictive system also optimized portion sizes and timing, improving user satisfaction. The response time decreased by 28% across 150 iterations, while the success rate increased from 75% to 90%, demonstrating the robot's learning and adaptability.

CONCLUSIONS

By leveraging time series decomposition, ARIMA, and FFNN, the feeding robot achieved substantial improvements in accuracy, responsiveness, and personalization. The integration of predictive algorithms and adaptive learning mechanisms allowed the system to model both long-term and short-term user interaction dynamics effectively. These advancements highlight the robot's potential to deliver a highly precise, safe, and personalized feeding experience for individuals with motor impairments.

Authors: Ridawati Ridawati , Alsuhendra Alsuhendra , Ramadani Muhammad Indera
Published: February 2025

Phaseolus vulgaris L, known as red bean, is a staple food in Indonesia. The temperature sensitivity of red bean limits the applications despite the high starch content. Therefore, this research aims to analyze the effects of heat-moisture treatment (HMT) on the properties of red bean starch, focusing on the functional and morphological characteristics. The effects of HMT (4, 5, and 6 hours at 110°C) were elevated on fresh and dried red bean starch using Completely Randomized Design. The results show that significant alterations were observed in starch properties due to HMT. Water absorption capacity (WAC) varied with HMT duration and fresh bean starch peaked at 4 hours (198.0 ± 0.1%) before declining at 6 hours (159.5 ± 0.7%). In contrast, dried bean starch showed a decrease from the native capacity of 223.5 ± 5.0% to 176.5 ± 5.0% after 6 hours of HMT. Oil absorption capacity (OAC) also changed markedly and fresh bean starch increased from 68.0 ± 2.8% to 85.5 ± 0.7%. Similarly, dried beans increased from 67.0 ± 1.4% to 83.5 ± 0.7% since the effectiveness of HMT enhanced starch interaction with water and oil molecules. In fresh and dry beans, swelling power decreased and increased with prolonged HMT, reaching a peak at 4 hours (8.57 ± 0.15 g/g). However, solubility index decreased in both types following an increase in HMT duration. The morphology of starch granules transitioned from round or elliptical shapes to more polyhedral and irregular forms, reflecting substantial structural changes. In conclusion, HMT effectively modified the functional properties of red bean starch to offer potential benefits for application in food industry.

Published: February 2025

Objectives: Helicobacter pylori is the major cause of duodenal ulcers and gastric cancer. Menaquinone is essential for the respiration and survival of H. pylori. Identification of compounds that have good binding affinity at the active site of MqnB will be the promising approach against H. pylori. This study aims to identify the natural lead compounds against MqnB enzymes in H. pylori through in silico methods.
Methods: As the three-dimensional structure of H. pylori MqnB is not available, we have modeled the three-dimensional structure followed by identification of the active site. The binding of the compounds from the COlleCtion of Open NatUral prodUcTs database was screened against MqnB, and dynamics simulation studies were carried out for the top three lead compounds.
Results: The predicted model of MqnB was subjected to a molecular dynamics (MD) simulation study to obtain the dynamic behavior of MqnB. The best representative model was validated and further used for structure-based virtual screening. Based on the docking results, three lead compounds were chosen among the top hits and subjected to 200 ns MD simulation. The results highlight the dynamic nature of MqnB in complex with the lead compounds and favorable binding interactions are comparable with the substrate. All the compounds showed promising interactions with MqnB during MD simulations.
Conclusion: Identified lead compounds show good binding potential and also maintain interactions with amino acid residues at the active site of MqnB enzyme. These compounds could be further explored in the drug discovery process against H. pylori.

Bridging the gap between scientists and the public: “Science v. Story”
Authors: Levy Douglas A.
Published: February 2025

Emma Frances Bloomfield's “Science v. Story: Narrative Strategies for Science Communicators”, presents ways to improve science communication in the face of declining public trust. Bloomfield's work highlights the power of narrative, demonstrating how anti-science movements have effectively leveraged storytelling to popularize their messages. If scientists adopt narrative strategies, they can bridge the gap between the scholarly community and the public and make complex information more accessible and relatable. Bloomfield's approach provides a roadmap for navigating the complexities of science communication in an era where many people are swayed more by personal connection than credibility or facts.

Authors: Fuadi Fuadi , Ramadhan Muhammad , Batubara Chuzaimah
Published: February 2025

Despite being the country with the largest Muslim population globally, Indonesia faces challenges in implementing halal food supply regulations, particularly in the meat industry. This study aims to explore the factors influencing the decision of actors in the halal meat supply chain in Aceh, Indonesia, to obtain halal certification for their products. Data was collected through structured interviews with 150 participants involved in the halal meat supply chain. The data analysis was conducted using Structural Equation Modeling with Partial Least Squares (SEM-PLS). The study applied the Theory of Planned Behavior (TPB) alongside government regulations on halal food and compliance to predict certification behavior through the intention to certify. The findings suggest that attitude, subjective norms, perceived behavioral control, halal regulation, and compliance influence the intention to certify, which in turn affects the behavior of the actors. This study demonstrates that intention to certify acts as a mediating factor in the relationship between these variables and the behavior of actors within the halal meat industry. These findings have substantial implications for both the halal food industry and regulatory bodies seeking to enhance halal certification rates in Indonesia.========================================================================================================ABSTRAK - Determinan Perilaku Sertifikasi Daging Halal di Indonesia: Analisis Theory of Planned Behavior.

Aim: to reduce the number of paracolostomy complications and improve the quality stoma patients’ life by justifying the use of a comprehensive approach to the end colostomy, including preoperative marking, taking into account the variants of the structure of the muscular-aponeurotic frame of the anterior abdominal wall, as well as the individual features of vascularity and topography of the intestine section undergoing ostomy surgery.Materials and methods. To confirm the effectiveness of the proposed algorithm, an analysis of 52 clinical observations in patients who underwent surgeries with the formation of an end colostomy was carried out, which made up two clinical groups. In group 1 (n = 25) the developed therapeutic and diagnostic algorithm was applied, which included a rational choice of the colostomy localization site, taking into account individual features of the anterior abdominal wall structure, the quality of vascularity of the ostomy intestine, the terminal portion of its mesentery, the length and topography of the end section. Group 2 of patients (n = 27) underwent ostomy creation surgery using traditional techniques, without considering individual features.Results. The obtained results indicate the possibility of reducing the number of early (group 1 — 16 %, group 2 — 40.7 %; p < 0.05) and late (group 1 — 8 %, group 2 — 29.6 %; p < 0.05) paracolostomy complications, decreasing the number of repeated surgical interventions (three cases of re-creation of the stoma in the early postoperative period in group 2 and no indication for repeated interventions in group 1) and improving the quality of life in stoma patient through the application of the developed personalized algorithm. The assessment of the psychological (group 1 — 33.24, group 2 — 53.41) and physical (group 1 — 32.46, group 2 — 54.78) components of health based on the results of the SF-36 survey confirmed the advantages of the proposed tactics and therapeutic and diagnostic algorithm in group 1. The average number of hospital-stay days was also less in patients of clinical group 1 — 12.1 ± 3.4 days vs. 16 ± 4.7 in group 2.Conclusions. The use of patient-centered complex approach to determining the place and method of formation of an end colostomy, which includes taking into account the individual structure of the muscular-aponeurotic frame of the anterior abdominal wall, and the peculiarities of vascularity and topography of the intestine section undergoing ostomy surgery, is accompanied by a low number of early and late paracolostomy complications.

Verdenssamfundet er i krise. Ikke mindst som sammenhængende verden, og som det Max Weber kaldte meningssammenhæng. Faktisk er der flere omfattende kriser oven i den Ukrainekrise, der er temaet for nærværende artikel. Hertil kommer den omfattende krise med orienteringen i rådvildheden, der omfatter alle disse krisers egne ’omfangslogikker’ – for nu at udtrykke det med den hedengangne århusianske mestertænker Hans-Jørgens Schanz’ lige så hedengangne marxistiske kapitallogik.

Transportation operations occupy a large share of all types of work in the transport
and technological support of agricultural enterprises of the Amur region, where the distance from
the extreme western point of the region to the extreme eastern one is over 1 000 kilometers, and the
distance between the southern and northern points is more than 600 kilometers. The main hypsometric
features are elevation changes from 500 to 1 500 meters above sea level. In addition to the
fact that the region has a large length of dirt roads, transportation operations in the region under
consideration are also complicated by significant distances between settlements. It should also be
noted that in a number of northern regions, cargo can only be delivered in the winter period on
temporary roads that have a different surface of movement according to adhesion conditions and
terrain features. All of the above features of the territory certain difficulties in the transportation
of goods, since car operations are limited by the conditions of transverse stability. When driving
on surfaces with a large angle of inclination, a sharp alternating redistribution of the weight load
between the movers occurs. It leads to breakdown of the units and components of the undercarriage.
One of the solutions to this problem is the introduction of technical devices that help to
reduce the variable load on the movers. A promising technique, as studies show, can be a way to
redistribute the weight in the chassis of the transport unit itself, which will increase the service life
of the propulsion units and the efficiency of the vehicle. This article presents the research findings
on improving the utilization efficiency of AWD vehicles of KamAZ brand for transporting cargo
with the installed redistributing device «Frame load regulator», for which the Russian Federation
patent No. 166665 has been obtained.

The paper presents the results of ecological testing of pea varieties of various
origins. The studies were carried out in 2015–2018 on the vegetable field of the Far Eastern Agriculture
Research Institute. The objects of the research were pea varieties of various ecological and
geographical origin. Promising lines and varieties were created and provided by the Federal Scientific
Center of Legumes and Groat Crops (lines L-102-07, L-104-13, L-75-06, L-20-03 with sarmentose
leaf type, variety Spartak and lines YaG-09-523, YaG-07-652, YaG-07-643, YaG-07-599, YaG-06-83,
YaG-08-1269, R-743-09 with longline heterophilia) and the Ulyanovsk Research Institute of Agriculture
(leaf variety Ulyanovets, sarmentose varieties Ukaz and Yubilyar). The standard was the
variety Aksaiskii usatyi 55. All studied varieties are characterized as mid-ripening, the growing
season was 74–77 days with a variability range from 12 to 20 days. The weather conditions had
the greatest influence on the duration of the germination-flowering period, while the temperature
regime was more significant. A positive relationship was found between the duration of the entire
growing season and the duration of the period from mass flowering to ripening (the correlation
coefficient reached 0.63±0.05). The maximum yield over the years of research was formed in the
standard variety Aksajskij usatyj 55 (26.7 c/ha) with an average yield of 23.3 c/ha. A high dependence
of pea yield on hydrothermal conditions during the growing season was revealed. It has
been established that it is the temperature factor in the conditions of the Middle Priamurye that has
a negative impact on the formation of the crop. As a result of the research, the samples Aksajskij
usatyj 55, YaG-06-83, YaG-08-1269 were selected, which had the shortest growing season in the
study group. The varieties P-743-09 and Yubilyar had the minimum duration of the period from
germination to mass flowering and the number of nodes up to first pod. Selected variety samples
can be used in breeding early-ripening pea varieties for the Middle Priamurye.

In modern conditions of intensive dairy cattle breeding, it is necessary to pay
special attention to the restoration of the organism of dairy cows in order to maintain a high rate
of recovery of the breeding stock. The introduction of the feed concentrate "Cowfresh" into the
main diet of cows during the initial lactation period for a short period of time had a positive effect
on the productive and reproductive indicators of dairy cows. The research was conducted in 2020
in the conditions of the livestock complex "MilANKa" (Gribskoye, Amur region). The experiments
were carried out on newly-calved red-and-white cows from the first to the third lactation,
selected according to the analogues pair’s principle, in three experimental groups and one control
group of 10 heads each. The purpose of the scientific and economic experience was to evaluate
the effectiveness of the use of the feed concentrate "Cowfresh" during the cow calving period for productive, reproductive and economic indicators at the first lactation phase. The duration of the
experiment was 110 days from the moment of cow calving. The experiment consisted of two stages.
The first stage was giving an aqueous solution of the feed concentrate "Cowfresh" in different
dosages to different experimental groups for 10 days once a day. The second stage was monitoring
the productive and reproductive qualities of experimental cows for 100 days. As a result of the experiment,
the positive effect of the feed concentrate "Cowfresh" on the recovery rate after calving,
productive and reproductive indicators of cows was established. The optimal dosage was 200 g
of the feed concentrate "Cowfresh" per 100 kg of live body weight. At the same time, the average
milk yield per one cow for 100 days of lactation in the second experimental group was 2 768.5 kg
of milk of basic fat content, which was 25.7 % more than the indicator of the control group.
