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.

Prevalence, treatment and prevention of ascariasis in turkeys
Статья научная
Ascaridiosis in turkeys is a parasitic disease caused by Ascaridia galli , one of the most prevalent helminth infections in poultry. This disease is particularly widespread among turkeys raised in semi-intensive or free-range systems and leads to decreased productivity, stunted growth, weakened immunity, and economic losses. Clinical signs include loss of appetite, weakness, poor feather condition, diarrhea, and growth retardation. In severe cases, it can result in mortality. Diagnosis is mainly based on microscopic examination of feces, where characteristic Ascaridia galli eggs can be identified. Necropsy of deceased birds may reveal large, white worms in the intestines, confirming the diagnosis. Treatment involves the use of broad-spectrum anthelmintic drugs such as albendazole, fenbendazole, levamisole, and piperazine, which are administered through feed or drinking water in specific doses. Correct dosing and treatment duration are essential for effective control. Preventive measures include regular disinfection of cages and equipment, maintaining hygienic and dry conditions, ensuring clean feed and water, and conducting periodic veterinary monitoring. Prophylactic deworming every 3-4 months is recommended to reduce infection risk. This study highlights the biology, epidemiology, clinical presentation, diagnosis, treatment, and prevention of ascaridiosis in turkeys, emphasizing the importance of early detection and control to maintain flock health and productivity.

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.

Research Into Effective Treatment Methods for Nosematosis (Pebrin) Disease
Статья научная
For the first time in the conditions of the Republic of Azerbaijan, research was conducted to develop medicinal preventive and therapeutic methods against pebrin (nosematosis) disease of mulberry silkworms, which causes serious damage to silkworm farms. The study used both naturally pebrin-infected and healthy cocoons of the Namazli-2 mulberry silkworm breed and the larvae emerging from them. During the experiments, 2.0% solutions of fumagillin DCH (1.0%), amprolium, coccidiovit and baycox preparations were applied. As a result of the effect of these preparations on cocoons naturally infected with pebrin, the mortality rate in the worm stage decreased by 17.36–16.31%, and the total mortality decreased by 22.22–19.99% compared to the diseased control groups. At the same time, the survival rates of silkworms increased by 19.99–22.22% against the background of the disease. The cocoon yield obtained from one standard box (20,000 cocoons) was also comparatively higher by 9.2–10.6 kg. These results indicate that the use of the mentioned preparations has an effective treatment and preventive effect against pebrin (nosematosis) disease of mulberry silkworms and significantly contributes to increasing productivity in sericulture farms.

Azerbaijan is known as one of the oldest sheep breeding countries. The natural and geographical conditions of Azerbaijan had a special impact on the creation and development of animal husbandry, especially sheep breeding. At that time, the tribes living in Azerbaijan were engaged in agriculture and cattle breeding, which led to great changes in their way of life. During this period, although people lived collectively, the main place in cattle breeding, especially in caring for it and feeding it, was occupied by men. In 1953, the animal breeders of the Nekhram village of the Nakhchivan (Babek) district purchased 2618 lambs from 2580 ewes. In general, based on the materials of the Babek and Shahbuz districts of the Nakhchivan region, it can be seen from the studies of the first half of the 20th century that, although for certain reasons there were certain difficulties in the development of sheep breeding in these districts until the 1920s, great success was achieved after 1920 with the creation of favorable conditions, success was achieved, and sheep breeding played a large role in meeting the financial needs of the population.

Specialization of phytophages of tree crops, their development and role, population management
Статья научная
The article discusses 80% of pests found in the orchards of Tashkent and Samarkand regions, their species composition, damage to trees and their parasites, as well as their populations, which cause particularly significant damage here. The number of predatory and parasitic entomophages is a major area of study. Environmental factors have a sufficient impact on the reproduction and development of forests. Due to the high relative humidity of the air, this environment becomes unfavorable for the development of certain insect species. In the forest, on ornamental trees, there is an abundance of natural insects that cause the destruction of plants. In this case, pests are leading. A decrease in the amount of water in a tree trunk is favorable for the development of phytophages.

This article has been investigated and evaluated by studying the specification of anatomical structure of the sort samples of tomatoes. Studies have shown that anatomical indicators mainly have a great importance in learning of drought resistance, determining the origins of the different varieties, choosing of hybrid plants in selection work of the size and number of stomata, and total thickness of the leaves. Studying of anatomical characters of tomato sort samples and hybrids plants has shown that learning of the total thickness of the leaf and the size of number of stomata has a certain importance in selection of hybrid plants. It is defined that in sort samples which their cuticle layer is thick, water evaporation decreases, and they become resistible to illness. So, the sample of Volgograd 5/95, 82 and 90 in upper epidermis and the sample of 93 in lower epidermis were differed for the thickness of cuticle layer. As results of studies, it has been identified that chlorenchyma present in the sort samples predominant for differing according to the total thickness of the leaf. Moreover, studying of the leaf cells has shown that the evaporation of water is higher in the leaves which the number of stomatas is more, and the epidermis cells are few, for that reason, the leaves of Solanum pimpinellifolium L. (wild form) are in thin needle shaped in order to reduce the transpiration. Exactly for this reason, it’s recommended to use the wild form as a donor in conducting the future selection work.

Rumen Protozoa are strictly anaerobic and highly specialized ciliates and can live only in the rumen and similar habitats. These Ciliata play an important role in feed utilization and indicate the environmental impact (methane emissions and nitrogen excretion) of ruminant production. Digestion of feed in ruminants depends on the life activity of microorganisms. Without their help, ruminants could not assimilate cellulose with simple non-protein compounds. These microorganisms located in rumen decompose the organic substances in the feed and form volatile fatty acids, ammonia, amino acids, which animals use for their development and reproduction. In the rumen of domesticated cattle and sheep, rumen cilia constitute 20-50% of the total microbial biomass. Rumen Ciliata develop symbiotic relationships with their animal hosts and both symbiotic and predator-prey relationships with other members of the rumen microbiota. The lack of axenic cultures of rumen Ciliata has forced researchers to use other methods to determine the metabolism and functions of rumen Protozoa, such as comparing rumen fermentation and microbial profiles of faunal and non-ciliated cattle or sheep or using in vitro cultures.
