Cooperation as a basis for increasing the economic efficiency in protected cultivation of vegetables
Статья научная
The main task of the greenhouse economy is to provide the population with fresh vegetables in the winter season period. Therefore, the cultivation of vegetable crops in protected soil differs significantly from the cultivation of many other crops. The content of the protected soil is justified only under conditions of high-intensity production and the costs of creating and operating a capital greenhouse facility, material costs for their heat supply, electricity. Work in greenhouses is associated with increased the need for skilled and auxiliary labor. The greenhouse production of Uzbekistan is mainly concentrated near large settlements. The industry allows you to receive from the sale of fresh vegetables at least 60% of cash proceeds, over 95% of the total profit of the economy, and the level of profitability from the sale products from year to year increased. The article draws attention to possible reserves of cost savings in the protected cultivation of vegetables.

Cultivation technologies and inorganic fertilizer norms when growing potatoes in Azerbaijan
Статья научная
Technologies for applying granular fertilizers when growing potatoes in the farms of the Gazakh-Tuz economic region of Azerbaijan are presented. An analysis of existing technical means used to effectively prepare soil for growing potatoes was carried out. By means of a stepwise supply of inorganic fertilizers to the soil using the method of differentiated distribution, theoretical studies were carried out and analytical expressions were obtained to substantiate the parameters of the working bodies of the corresponding unit. An analysis of existing technologies and technical means for growing potatoes shows that the application of fertilizers, which provide the required amount of nutrition for the cultivated crop, prevents sufficient nutrition of the soil when carried out in a surface manner and subsequent incorporation into the soil. To avoid this, inorganic fertilizers are applied to the soil by working groups and converted into the soil by cutting off lower layers to protect the mound and optimal soil structure. By systematically filling the soil through differentiated distribution of inorganic fertilizers, analytical studies were carried out and analytical expressions were obtained to check the parameters of the unit’s labor force.

Cultural lacunae: lacunas of activity as intercultural communication in translation
Статья научная
The article deals with the translation issues of lacunas of activity as cultural lacunae which are an integral part of the Kyrgyz culture and adequate interpretation of which plays a great role in intercultural communication. Through translated works of art cultures undoubtedly communicate in many ways. Traditions, rituals and other behavioral peculiarities characteristic to one culture might be quite unknown or even seem strange to foreign readers. The author tried to give examples for lacunas of activity described in the novels by Ch. Aitmatov and to show the difficulties of lacunas of activity translation as none of the methods proposed by scholars can be used in transforming them into English. Comparing lacunas of activity in the ST and TT, it has been found out that gestures, movements, actions that follow talking reflected in the works of art can’t be eliminated, compensated or commented in literary translation therefore it will be challenging for foreign recipients. Indifferent readers will find them strange while concerned ones will get more information about another culture. This way cultures communicate with each-other through translation.

Current Status of Caryophyllaceae Juss. in the Lachin District
Статья научная
The article provides information on the biological, ecological, and coenosis-forming characteristics of representatives of the Caryophyllaceae Juss. family found in the Lachin district, their distribution patterns, and limiting factors for the protection of rare and endangered species. The research was mainly carried out in mountain-meadow tall-herb meadows, forest-meadow vegetation, and steppe vegetation types, as well as in various plant communities. The abundance of Caryophyllaceae Juss. representatives in plant communities was assessed at 1–2 points. Studies on populations of Minuartia intermedia (Boiss.) Hand.-Mazz. revealed irreversible unidirectional changes. A gradual decrease in the number of M. intermedia populations and high sensitivity to adverse environmental factors were observed. Without timely conservation measures, the populations may completely disappear. The species Paronychia azerbaijanica Chaudhri was found in the Lachin district within mountain steppe and mountain-xerophyte steppe vegetation types in the form of localities. A decreasing trend in the number of individuals was observed, making conservation measures necessary. This species is included in the third edition of the “Red Book” of Azerbaijan. Direct observations and studies on populations of Silene cephalantha Boiss. revealed that, due to anthropogenic factors, the quality of the habitat has declined (A2ac). The growth dynamics of individuals were found to be at a low level. The absence of young individuals indicates an ongoing continuous decline (C1). In the observed area, only 3–5 individuals were found per 10 m². All these factors indicate a potential threat of extinction in the future. Therefore, the development dynamics of the species should be monitored.
