Management of integrated pests and diseases in greenhouse crops
Статья научная
It emphasizes the importance of sustainable practices and environmentally friendly solutions to ensure long-term success in pest and disease management. By integrating various control methods, growers can create a balanced ecosystem that promotes healthy crop growth and reduces the risk of pest outbreaks. IPM systems offer a valid potential to reduce reliance on conventional pesticides in arable crops by integrating non-chemical tools and diversified crop rotations. The adoption of IPM practices can lead to overall sustainability in crop protection, benefiting the environment and contributing to the health and quality of the crops being produced. However, the final outcome of widespread adoption may not always lead to increased income. The shift in supply resulting from IPM adoption can increase producer surplus, equated with farm income, but there are cases where aggregate income may decrease even with inelastic demand. The microeconomic impact of IPM adoption varies based on crop and location specificity, with some studies showing an increase in farm profits while others find no effect on pesticide expenditures among farmers in different regions. Standardizing IPM costs can be challenging due to varying factors such as the type of treatment, product costs, and technician time involved in the process. Collaboration among farmers is essential for staying ahead of pest challenges and promoting sustainable farming practices that are both environmentally friendly and economically viable. By working together and sharing best practices, farmers can collectively address pest issues in a more coordinated and effective manner, ultimately leading to healthier crops and increased productivity.

Mastitis and its comparative treatment methods
Статья научная
Modern scientific data confirm that mastitis is a major problem in dairy farming in all countries of the world, and its subclinical form, unlike the clinical manifestation, is the most common. In addition, literature data allow us to conclude that mastitis is a polyetiological disease. On the one hand, its occurrence is caused by infectious agents (bacteria, mycoplasmas, fungi), and on the other hand, by the influence of environmental factors that reduce the resistance of the animal organism. The predisposing and accompanying factors for the development of this disease have a great influence. The first includes the body's resistance and the immune status of the animal, the second includes non-compliance with zootechnical, preventive and therapeutic measures, non-compliance with udder hygiene before and after milking, lack of control over the serviceability of milking. Inadequate disinfection of machines, as well as milking systems. Since mastitis remains one of the most common diseases of dairy herds in the world, it can be assumed that the required zootechnical, preventive and therapeutic measures are not fully observed in farms engaged in the breeding of dairy cattle. By strengthening control over the implementation of a number of measures, it is possible to reduce the number of cases of clinical and subclinical mastitis in cows. Specific prevention is the most effective method of combating mastitis, but the formation of stable and dense immunity can be achieved only by strict adherence to a certain list of zoohygienic and technological requirements.

Modern comparative characteristic of mountain meadow soils in Azerbaijan
Статья научная
The northeastern slope of the Lesser Caucasus occupies a large territory in the western part of Azerbaijan. One of the most widespread soils in Azerbaijan is mountain meadow soils. The purpose of the research is a comprehensive and comparative study of morphodiagnostic parameters, physicochemical properties and biochemical activity of natural and anthropogenically modified biogeocenosis of mountain meadow soils of the Gadabay District. Some results of many years study are described in the article. Villages like Gara Murad, Kichik, Garamurad, Saratovka and others were researched. The research was carried out on virgin soils and cultivated lands in villages. A total of 15 land plots have been allocated, some of the research results are presented in the article. Carrying out numerous agro-reclamation activities, we managed to attract uncultivated land to agriculture and obtain high-quality products. The groundwater level in these areas exceeds 2 meters, and the salinization processes are active. Comparative results from all these agro-chemical studies helped to get virgin soils into agriculture in the plains and achieve high productivity. This can be invaluable literary material for a new generation of soil scientists.

The aim of this study was to evaluate morphologic features, diagnostic qualifiers and enhance classification of alluvial-meadow soils in the floodplain of the Kur River within Azerbaijan. For this purpose, several soil pits were placed in the representative test areas and multiple soil samples collected within field campaigns (2014-2015). Based on the field and laboratory test data, the detailed soil maps of the test areas were compiled, and diversity of alluvial-meadow soils was classified as suborders (subtypes): alluvial-meadow primitive; alluvial-meadow layered (flaggy); alluvial-meadow dark and alluvial-meadow irrigated. It was found out that in the floodplains, local soil variability was predominantly attributed to not only alluvial sediments, but also water table, mineralization rate and salt content of underground water as well flood water play an important role. The mineralization of ground water is weak (1.40-3.70 g/l) and the concentration of hydro-carbonates (HCO3-) varies from 0.56 to 0.92 g/l. No salinization indication found in the profile of alluvial-meadow primitive and alluvial-meadow layered soils, while weak concentration (solid content = 0.40-0.54%) was found at a depth of 80-150 cm in the alluvial-meadow dark soil. Unlike other subtypes, alluvial-meadow dark soil is characterized with the higher biomass (green weight of top = 41.5 cwt/ha and green weight of underground = 142.3 cwt/ha), high mobility of humus substances with predominance of the 1st fraction of humin (20.0-28.1%) and fulvic acids (14.6-22.3%). The ratio of Cha : Cfa reaches 1.18-1.32. For the alluvial-meadow irrigated soil, the second fraction of humin acid (9.3-10.2%) and total content of humin acid ranges from 45.6 to 50.3%. The ratio of Cha : Cfa is larger (1.37-1.50). Depending on the lithology of alluvial sediments, the content of SiO2 and R2O3 varies in the ranges of 53.0-57.2% and 9,6-26,0%, respectively. For the alluvial-meadow dark soil, decomposition of alum silicates in alkaline hydrolysis is typical (8.7-9.0). The content of SiO2 and R2O3 varies between 47.8 and 50.6 %, and 19.7 and 21.6%, respectively. In the topsoil, of the irrigated soils in associated to washing out the content of Ca and CaO content (12.2-13.1%) increases in deeper horizons.

It is established that in pig farms of various forms of ownership the number of animals with violation of reproductive function makes from 11.7 to 39.7%. As a result of the clinical examination of the basic herd of pigs revealed that obstetric pathology occurs on average 40.1 percent of broodstock, with 26.7% of the sows in the period of pregnancy registered gestosis with a classical triad: hyperhydration, hypertension and proteinuria. Depending on the symptoms, there were 4 forms of pregnancy complications with gestosis with symptoms of anemia (38.4±1.89%), hepatopathy (27.8±1.2%), nephropathy (34.5±1.7%) and paraplegia (9.3±0.7% of pregnant sows). Diseases of pregnant sows were clinically manifested by events of oppression - loss of appetite, pallor of visible mucous membranes, soreness of palpable area of the liver, proteinuria, hypertension, disorders of the Central nervous system, calving mobility problems, yellowness of the eyeball. Morphometric studies of the placenta in the gestosis of pregnant sows evidence that the length of the umbilical cord, the mass of the maternal part of the placenta, the thickness and volume of the child part of the placenta is reduced to a statistically reliable magnitude, compared with similar indicators in clinically healthy pregnant sows. Noted a significant fluctuation of fetus-placental ratio with an inverse of value. There was a significant fluctuation of the fetal-placental coefficient with the opposite value, in piglets born from clinically healthy mothers. The functional status of newborns depends on the forming processes of the maternal and child placenta, as well as the morphological and physiological properties of the development of fruits, which is confirmed by an authentic decrease in the body weight of newborns by 30.0-40.0% and weakly expressed motor-food reflexes.

Morphophysiological parameters of hard and soft wheat genotypes depending on different water supply
Статья научная
To determine drought tolerance of 10 wheat varieties (3 durum and 7 bread) differing in architectonics, the research was performed under normal and drought conditions. The reduction in the plant height due to cultivation conditions rather than genetic properties of the genotypes occurred because of the decreasing length of upper internodes by 0.47-9.51%. Structural components of the product were determined. The greatest reduction in above-ground dry biomass per unit of the field was detected in Barakatli 95 and Garagylchyg 2 genotypes. The amounts of pigments were determined to evaluate the level of the photosynthetic apparatus development, its physiological state, formation and accumulation potential of the product. The content of chlorophyll a, b and carotenoids was determined during the grain forming, milk ripening, and wax ripening phases. Green plastids were broken down and chlorophyll content decreased under drought. Chlorophyll a content decreased more sharply compared with chlorophyll b. Chlorophyll a content decreased more sharply in all phases in the durum variety Barakatli 95 (during the phases, respectively, 19.7; 16.6 and 35.6%) and bread variety Gyrmyzy gul 1 (21.9; 15.3; 39.5%). Chlorophyll b amount decreased less in the durum variety Tartar (11.0; 7.30; 14.2%) and bread variety 4th FEFWSN-50 (4.83; 10.8; 9.20%). Amounts of the photosynthetic pigments were determined in various regions (Gobustan and Jalilabad Regional Experimental Stations). Chlorophyll a content decreased more in the Gyrmyzy gul 1 and Garagylchyg 2 varieties (in Gobustan: 2.302 and 2.979 mg/g fresh weight) in Jalilabad: 2.096 and 2.737 mg/g fresh weight) under rainfed conditions. Drought had a relatively less impact on chlorophyll a content in the Azamatli 95 and Gobustan varieties. Chlorophyll b content ranged from 0.033 to 2.398 mg/g fresh weight in Gobustan and from 0.057 to 2.175 mg/g fresh weight in Jalilabad, whereas the content of did not decrease.

New method of using mobile robots for implementing warehouse operations
Статья научная
The new patented method of movements of packaged cargoes at the warehouse is proposed in this article. The proposed method of loading is superior in economic efficiency, reliability, cheapness, simplicity of construction and use, to all other methods of loading implemented by robots. The method allows the mobile robot to load a cargo which is three times as heavy as this mobile robot, wherein almost no electrical energy is consumed during loading. In implementing the method, two mobile robots are used, each of which contains a mobile platform, an omnidirectional mobile wheel-type mechanism and a transport suspension with independent suspension for each wheel. Actually, mobile robots help each other to load cargo on the first mobile robot, through robot cooperation. Loading of the container with the load on the first mobile robot is carried out by actuating a two-arm lever, which is carried out through the impact of the bottom of the mobile platform of the second mobile robot on the longer arm of the two-arm lever by lowering the mobile platform of the second mobile robot due to the operation of the transport suspension of the mobile platform of the second mobile robot. For example, if the length of the longer arm of the two-arm lever is three times longer than the shorter arm of the two-arm lever then the second mobile robot of weight 50 kg is capable of loading a container with a load of weight 150 kg on the first mobile robot.

Organic agriculture in Turkey and the world
Статья научная
Organic agriculture is an alternative production system that supports soil structure, fertility and conservation by protecting the ecological balance, using biological control methods against diseases and pests; based on the sustainability of living life, aiming for the highest yield with the maximum use of natural energy resources. In this context, it covers a different production process from conventional agriculture. While intensive input applications in conventional agriculture aim for the highest yield, organic agriculture prioritizes sustainability. Sustainable agriculture is defined as an agricultural practice that protects soil, water and biodiversity while meeting food, energy and natural resource needs. To ensure that organic agriculture contributes to sustainability goals, organic regulations need to focus more on environmental and best practices. Increasing demands day by day have positively affected the sustainability of organic agriculture. The common feature of most of the definitions of organic agriculture is that the products should be produced in accordance with the basic standards and that every stage from the land to the table is regularly controlled. The fact that every stage of organic agriculture is audited and documented, and that the practices operate in accordance with legal procedures are other noteworthy elements. These legal procedures provide protection at many points. Organic agriculture is not only limited to safe food production to protect human health; it is also an agricultural and ecosystem management that is environmentally friendly, effective in reducing ecological pollution, protection of water resources, prevention of erosion, protection of biodiversity, agricultural sustainability and agricultural development.

Pisum sustainability system to Na2SO4
Статья научная
Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or sustainability to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity stress at different levels and an integrated approach of combining molecular tools with physiological and biochemical techniques are imperative for the development of salt-stable varieties of plants in salt-affected areas. Recent research has identified various adaptive responses to salinity stress at molecular, cellular, metabolic, and physiological levels, although mechanisms underlying salinity tolerance are far from being completely understood. This paper provides a comprehensive review of major research advances on biochemical, physiological, and molecular mechanisms regulating plant adaptation and sustainability to salinity stress.

Product quality in mixed cropping of groundnuts (Arachis hypogaea L.)
Статья научная
The article notes that the groundnuts crop yield in mixed cropping is the result of a combination of plant growth and development, photosynthetic activity, biomass harvesting and other aspects of increasing crop performance in specific soil and climatic conditions and depends on agricultural practices. In indoor practice, it has been found that the use of mixed cropping not only increases crop performance, but also improves crop quality. The amount of oil contained in groundnuts seeds, along with fast growing tomatoes, increased by 2.7% compared to groundnuts sole cropping. When sowing groundnuts with potatoes, a slight decrease in oil content was observed (49.5%). The content of proteins in this variant decreased by 2.4-1.5% compared with groundnuts sole cropping. The quality of potato tubers, including the amount of starch, changed in mixed cropping. When mixed cropping groundnuts and potatoes, the starch content in potato tubers increased to 25%. The quality of the tomatoes has also changed. The amount of vitamin C contained in medium and early ripening tomato varieties increased to 17.3-17.9 mg/%. This is 0.6-0.9 mg/% higher than on tomato sole cropping.

Productivity of certain varieties of apples and importance of their gene formation
Статья научная
Due to the diversity of its natural and historical conditions, Azerbaijan is one of the centers of the initial formation of many plants, having a great genetic richness of the plant world. A large number of valuable varieties and forms of food and agricultural plants have been created through folk selection and scientific selection, with the history of agriculture covering several millennia. However, massive and anthropogenic disturbances of all these natural and cultural heritage ecosystems, which are the irreplaceable wealth of the people, created a large number of valuable varieties and forms of ecological and agricultural plants. However, all this natural and cultural heritage, which is the irreplaceable wealth of the people, is threatened with destruction as a result of mass and anthropogenic disturbances of ecosystems, ecological and agricultural changes, and the wide application of modern breeding achievements. In addition to all this, the study, protection, and effective use of the gene pool of the apple plant in the country is one of the main factors. In this regard, based on our long-term research, with the efficient use of the gene pool of the apple plant in Azerbaijan, new “spur”-type selection varieties (Nigar, Ziya, Zirva, Marfa, Sulh, Gobustan, Zumrud, Kyzyld Taj, Khazar, Eldar, Ulvi, Nübar, Vatan, Makhmari, Nuran, Sarvan, Chiraggala, Davamli, Emil, Elvin, Paizliq Guba, Zizliq Guba, Shabran, Sadaf and Sevinj) were created by us. In the article, the parental pairs of those cultivars are reflected in the ripening period, ripening, fruiting periods, tree parameters (height, diameter of the umbel, circumference of the stem), productivity indicators, leaf surface, infection rates of scab disease, average mass of fruits and tasting prices. At the same time, the article contains the introduction, research conditions, methodology, material, results, discussion, recommendations, and used literature sources.
