Sustainable farming practices include a variety of approaches. The most important approach to sustainable agriculture is crop diversification. This allows farmers to use biological cycles to minimize costs, conserve the resource base, maximize crop yields, and reduce environmental risk. It serves as an important opportunity to augment income and employment generation for rural communities. In contrast to specialized agriculture, crop diversification can be defined as an attempt to promote crop diversity through crop rotation, perennials or mixed cropping with the aim of improving crop performance, sustainability and supply of ecological systems. This can be a step towards more sustainable production systems, value chains for small crops and socio-economic benefits. Expanded agricultural diversity, better crop rotations, mixed cropping, cultivation of grain legumes in systems that are generally dominated by cereals, perennials, and regionally adapted (specialized) varieties are all examples of crop diversification strategies. As a result of the research carried out in the article, it can be noted that by carrying out the crop diversification under the irrigation and the same cultivation conditions, it is possible to obtain high and quality grain products from the varieties of feed peas Azerbaijan 1508 (green mass), wheat Gobustan and barley Jalilabad-19. This method is considered to be efficient both economically and cultivatically.

The effect of exam stress on age dynamics of vegetative indicators of choleric students
Статья научная
The aim was to find out the effect of the higher nervous activity on the post-exam autonomic nervous system indicators during the emotional stress of the exam process in students with a choleric temperament type of the age limit of 17 (1st year). Physiological indicators of different states of excitement and temperament type were first studied in the experiment. In order to comprehensively assess the effect of emotional stress on students of different ages and courses, we measured arterial pressure and the number of heart beats per minute, which are the main hemodynamic indicators. The research was conducted 2 months before the exam, 30 minutes before the exam and 30 minutes after the exam. Before starting the research, the temperament types of the young people were studied after the nervous examination. The situational anxiety of young people with different temperament types was determined by post-test scores in three different situations: on regular days, before the exam and after the exam. The results of the conducted research show that there are differences in the activity of the autonomic nervous system in students of different ages. The analysis of the results of the hemodynamic changes that we obtained from the effect of exam stress on groups also shows that the autonomic index of the credo is in a state of dominance of the sympathetic tone on an ordinary day and before the exam. The characteristics of the autonomic nervous system after the exam have a direct effect on the adaptation of a person. An increase in the level of the agitation process caused by one or another influence of ASF temperament types indicates the exacerbation of the credo's vegetative index in all groups. An increase in the level of excitement correlates with an increase in the activity indicators of the sympathetic branch of the autonomic nervous system.

The erythroformula and leucoformula indicators changed in the rabbits that experienced hypokinesia during the embryonic stage of pregnancy. Compared to the rabbits that spent the pregnancy period under normal conditions, changes in concentrations of leukoformula indicators such as leukocytes, lymphocytes, monocytes, and granulocytes were detected in rabbits exposed to hypokinesia. While significant changes in erythroformula indicators: erythrocytes, average corpuscular volume of erythrocytes and hemoglobin capacity, erythrocyte sedimentation rate did not occur. The results of our studies have shown that prenatal hypokinesia causes noticeable changes in the blood coagulation system. On the other hand, changes in the coagulation system under the influence of prenatal hypokinesia were found to occur in the first periods of postnatal ontogenesis, had a continuous nature, and were maintained until the full maturity of postnatal development. Due to the effect of the hypokinesia factor, the changes in the mentioned indicators lead to the emergence of severe pathological diseases in most cases.

In 2022, research work was carried out on three rice varieties in the village of Shikhakaran, Lankaran district: Govhar (regional), Sarykiprik (local) and Avangard (improved). Soil samples were collected and analyzed taking into account the introduction of various organic fertilizers, including nitrogen, phosphorus and potassium in five variants and three replicates. Phenological observations were carried out and the qualitative and quantitative indicators of plants were studied. According to the results obtained, it can be noted that rice growth varies from 109.3 to 148.0 cm, plant bushing is 6.7-15.5 cm. The highest bushing was noted against the background of mineral fertilizer in the Govhar variety. The length of the lateral shoots is at least 21.5 cm, maximum 25.2 cm. Accordingly, the number of grains on the lateral shoots is 56.0-109.4 pcs. On the lateral shoots, the highest indicator was observed in the Govhar variety - 2.0-5.2 g. The productivity of the Govhar variety against the background of mineral fertilizers was 25.5 g, and for the Avangard variety - 23.3 g. The thousand seed weight is 23.2-33.1 g, and the Govhar, Sarykiprik, Avangard varieties were distinguished by relatively high indicators against the background of mineral fertilizer. In grains, in terms of protein content, against the background of organic fertilizer, the Govhar variety was 9.03%, against the background without fertilizer, the Sarykiprik variety - 9.3%, against the background of organic and mineral fertilizer, the Avangard variety - 8.87%. No differences in the amount of sugar in seeds were found between the varieties.

The effect of salt solutions on the DMDH enzyme activity in the Hordeum vulgare primary incubation
Статья научная
Plants are subjected to a wide range of environmental stresses which reduces and limits the productivity of agricultural crops. Two types of environmental stresses are encountered to plants which can be categorized as abiotic stress and biotic stress. The abiotic stress causes the loss of major crop plants worldwide and includes radiation, soil salinization, floods, drought, extremes in temperature, heavy metals, etc. Abiotic stresses such as drought (water stress), excessive watering (water logging), extreme temperatures (cold, frost and heat), soil salinization and mineral toxicity negatively impact growth, development, yield and seed quality of crop and other plants. In future it is predicted that freshwater scarcity will increase and ultimately intensity of abiotic stresses will increase.

The effect of some elements of cultivation in stubble on the glycine max performance
Статья научная
In the irrigation conditions of Azerbaijan, the cultivation of Glycine max in stubble fields after harvesting the barley crop along with spring sowing is also economically very important. Sowing in stubble fields makes it possible to obtain additional grain yield and fodder from a single area, and to use reclamation facilities efficiently. At this time, the soil is provided with organic matter for autumn planting, and at the same time salinization is prevented, soil erosion and weed control issues are fully resolved. Cultivation of stubble field crops in large farms increases the possibilities of more efficient use of labor force, irrigation networks, agricultural machinery and equipment. During the conducted research, different results were obtained regarding the effect of different irrigation regimes and fertilizer rates on soybean grain yield. The resulting productivity depended on the plant coverage factor, leaf surface area, changes in wet and dry biomass. The smallest indicator of the yield was 10.0 centners in the variant with soil moisture of 60% before irrigation, and the highest indicator was 25.8 cwt/ha in the variant of the fertilizer rate calculated when the soil moisture was 80%, which is the same as the yield obtained from the autumn sowing of barley of the previous year (39 cwt/ha) together, it is equal to the yield of 67.9 cwt/ha from 1 hectare of land in one year.

Pneumothorax is a pathological condition characterized by the accumulation of air in the pleural cavity, which leads to loss of negative pressure and collapse of the lung. Traditionally, pneumothorax is divided into traumatic and spontaneous, if in the first case the cause is clear, then in the second case, the diagnosis is sometimes difficult. Particular interest to thoracic physicians is spontaneous pneumothorax (SP), which often develops as a result of rupture of a bulla or bleb. Drainage of the pleural cavity is an effective method of treatment, it allows to stop respiratory failure and straighten the lung in the shortest possible time. The problem remains the high recurrence rate, which, according to the literature, ranges from 20 to 40% after the first episode of pneumothorax. Describe the main causes of pneumothorax. Describe the possibility of using chemical pleurodesis (CP) to prevent relapse. Evaluation the efficacy and safety of CP with iodpovidone. The study was made on the basis of the clinic named after I.K. Akhunbaev National Hospital of the Ministry of Health of the Kyrgyz Republic in the Department of Thoracic Surgery. The study included 115 patients with pneumothorax of various etiologies who were treated in the department from September 2015 to February 2023. The control group included 62 patients, here traditional treatment was carried out by drainage of the pleural cavity. The number of people in the test group was 53, here, after complete expansion of the lung, a CP procedure was performed in order to prevent recurrence. If the patient underwent only drainage of the pleural cavity, then the recurrence rate was compared. If the patient underwent thoracotomy with bullectomy, then the frequency of postoperative air leaking was assessed. The safety of the technique was assessed by the main indicators of hemodynamics, temperature and pain response. CP with iodpovidone after drainage of the pleural cavity, as well as as the final stage of open thoracotomy, turned out to be 100% effective in preventing recurrences, as well as postoperative air leaking. Statistical processing showed the safety of CP with iodpovidone. CP with iodpovidone can be successfully used as a prevention of relapse, as well as the prevention of postoperative air leakage. The positive effect was in 100% of cases with minimal side effects.

The essence and content of family education in creative activity by Mevlana Jalaladdin Rumi
Статья научная
For the first time in the article, the goals and objectives of the family, as well as the concept of the family in the works of the messenger of morality Mevlana Jalaladdin Rumi, became the subject of research and analysis. The researcher notes that in his works, Mevlana Jalaladdin Rumi paid special attention to the issues of family education of children, deeply studied the historically established system of family relations and clarified many problems associated with family education that previously could not be solved by teachers, psychologists and philosophers. The researcher who developed the idea that “while the child is still in the womb, the mother’s feelings are transmitted to the child”, Rumi believes that the mother should be pure, moral, cheerful, smiling, full of happy moments, minutes, hours. It takes days and months for the unborn child to receive nourishment, fertilization and formation in this spirit. The article also examines the works of Hazrati Ali, Balasagunlu Yusif, Nasreddin Tusi, coinciding with the views and opinions of Mevlana Jalaladdin Rumi, and provides examples. It is shown that Mevlana considered the child a soul, a treasure, a wonderful good of the family, and considered the main factor to educate a child in the spirit of honesty, truthfulness and nobility from an early age, he must be accustomed to hard work, loyalty, loyalty, honesty and modesty. The article argues that the decency of parents in the formation of such superior qualities is an important factor. The pedagogical meetings of the great thinker, poet and scientist Mevlana Jalaladdin Rumi on family education were summarized by the researcher and completed with the provisions.
