Effective cultivation of corn on the drylands with the use of CAM liquid fertilisers by the “Tuman” innovative complex

In the presented material of the Samara State Agrarian University and Don State Technical University, the results of research on improving technologies for cultivating grain corn on the drylands using nitrogen, mineral, liquid fertilisers based on a carbamide-ammonia mixture — CAM are considered: CAM-32, CAM+S produced by PJSC “Kuibyshev-Azot” (Togliatti, Samara region), introducing them with an innovative, agrochemical, modular, multifunctional complex “Tuman...” (LLC “Pegas-Agro” — Samara). With a significant demand of corn for moisture and nitrogen fertilisers, it is very difficult to get a high yield without irrigation on the drylands, and therefore various technologies for using more effective liquid fertilisers instead of solid ones are being investigated in a region with insufficient moisture supply: in the Samara region of the Volga region of the Russian Federation. CAM has specific properties to cause “burns” of corn leaves; corn is a promising, highly productive crop with a great need for a macronutrient-nitrogen in the composition of a carbamide-ammonia mixture, and therefore to minimise this disadvantage, special extension hoses should be applied to hose sprayers, but they also have a technological disadvantage: corn foliar feeding requires additional moisture in the form of intense summer precipitation for the delivery of fertilisers through the soil layer to the root system zone. Thanks to the appearance of the foreign “Duport” aggregate, this problem is solved by special injection working bodies when applying CAM in the soil internally. The successful import substitution of the Duport unit was carried out by LLC “Pegas-Agro” (Samara, Russia) as well as by many other enterprises, creating a special module: the multi-injector “Tuman” for injecting more effective CAM

Improvement of wheat cultivation technology with Increased yield and product quality

The article is devoted to into the study of the optimisation of the process of using liquid nitrogen mineral fertilisers based on a carbamide-ammonia mixture, both in the serial form of CAM-32 and in the innovative CAM+S (with the addition of the sulfur mesoelement (S)) as a top dressing for winter wheat in spring during tillering. The application process was carried out superficially on crops with large-drop nozzles with a serial rod sprayer “Tuman-2” and an injec-tion-innovative multi-injector unit “Tuman-2M”. The article presents the improvement of the technology of cultivation of winter wheat of the "Basis" variety with the use of liquid mineral nitrogen and nitrogen-sulfur-containing fertilisers. The results obtained will improve the technology of wheat cultivation and improve the quality of the crop. The results of the research are an in-crease in yield compared with the use of granular solid mineral fertilisers: ammonium nitrate with the same nitrogen equivalent from 16.7 to 2.64 t/ha or from 34.5 to 58.1% and an improvement in grain quality to the level of class I compared with class III wheat quality when it is cultivated us-ing innovative technologies described in this work

Approaches to probiotics properties testing using Caco-2 cells

Adequate biological models are a prerequisite to screening and development of probiotic drugs. In the present study, Caco-2 cell line is reviewed as a model for analyzing properties of probiotics. This cell culture possesses all the characteristics necessary for evaluating the effects of probiotic drugs on a wide range of both intracellular processes and intercellular interactions. Informativeness of Caco-2 cells is in the focus of the present review
