Gooseberry is one of the common berry crops in Siberia. But despite its merits, the gooseberry is characterized by a weak development of plant phytomass when propagated by stem cuttings, and as a result, a decrease in the quality of planting material. The results of studies of various backgrounds of non-root fertilizing showed that the variant using exogenous treatments of Zn 1% + Cu 1% + 6 micronutrient elements showed an increase in the area of the leaf blade to 12.9 cm2. The accumulation level of copper, zinc, manganese and cobalt on plots using leaf fertilizing exceeded the control. Non-root feeding of Zn 1% + Cu 1% + 6 micronutrients of gooseberry when growing planting material by the green cuttings method increases the level of micronutrient accumulation (Zn, Co, Mn) in the leaves and activates growth processes – contribute to the development of assimilation surface.

The Cost

Ever increasing demand for food and fodder due to growing population and livestock necessitates the urgency to improve productivity of the fodder crops. In this context, the concept of vegetative propagation technologies serves as an important tool for higher productivity. Conventionally, crops such as sugarcane, cassava, bajra napier hybrid grass and napier grass were cultivated by stem cuttings. This depends heavily on the quality of planting material and their availability. It is a huge barrier for the cultivation of fodder grass as the quality of planting material influences the sprouting, establishment, growth, tillering and fodder yield of grasses and also the higher requirement of planting material increases the overall cost of cultivation. Therefore, a more robust approach needs to be developed to address these limitations. Normally propagation by vegetative means assumes importance when desirable biotypes need to be multiplied in a short span of time. Also a suitable method of planting and number of buds reduce the cost of cultivation as well as transportation. Similarly one and two budded setts are ideal for optimum germination compared to larger seed pieces. Horizontal planting of stem cuttings is the most practical approach which increased sprouting and yield. Based on this ideology this paper reviews the various aspects of influence of planting methods and number of buds by vegetative propagated setts on sprouting, growth and productivity of fodder grasses.

Sweet mock orange f. golden dwarf (Philadelphus coronarius L. f. aureus nanus) is a promising ornamental shrub in green building within Central Russia. In the Orel Region, this species has a limited occurrence due to the lack of quality planting material, which warrants research into rhizogenesis of P. coronarius f. aureus nanus stem cuttings during soſtwood graſting. Trials were conducted during 2017-2019 in triplicate, 20 cuttings each, adhering to the common woody plant soſtwood graſting propagation technique. Two yearling types were used, side shoots and innovations. Experimental setups: 1 — control (water); 2 — aqueous indolebutyric acid (IBA) 50 mg/L at 18-h exposure; 3 — bottom cutting powdering with 0.5 g/kg active coal-IBA mixture; 4 — bottom cutting treatment with 50 mg/L IBA at 18-h exposure followed by powdering with 0.5 g/kg active coal-IBA mixture. Setup 2 (IBA 50 mg/L) rendered the highest positive effect on the rooting and reproduction of side shoot and innovation-derived stem cuttings. Te best cutting root system biometry (number and length of 1st order roots) was obtained in setup 2 with the innovation cuttings (10.50 roots of 4.53 cm) compared to the side-shoot ones (9.81 roots of 3.68 cm).

The biological effects of sapropel in the technology of growing sea- buckthorn seedlings are studied. It is established that the rooting of green cuttings of the studied varieties on the sapropelic substrate is higher compared to the classic version – peat + sand by 2,0 – 31,3%. It is revealed that the composition of the substrate, the use of the root formation stimulator and varietal characteristics of culture influence the further development of plants grown by the non-transplant method at the place of green cuttings rooting. The most positive effect on the quality of the sea-buckthorn planting material is obtained on the substrate of peat + sand. It is recommended to use the sapropel-based substrate for rooting of the sea-buckthorn stem cuttings in the production conditions, and to apply the transplant method for seedlings further growing.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

Quality Indexes

The analysis of literature sources shows that the type and material from which the packaging is made has an important place in the system of factors which influence on the storage of feed products and also prevents reducing the quality of raw materials and finished products. Therefore, the purpose of our research is the technological justification of changing the quality indexes of premix samples with salts of trace elements of different chemical nature in the process of storage. For the solution of the tasks, common zootechnical and statistical methods of the research were used. The use of premixes in feeding pigs is based on the fact that they should be used taking into account the biogeochemical properties of the region for which they are calculated. Foods depending on regional properties have a special biochemical composition and excess or lack of individual substances should be offset by the composition of premix. Ignoring this provision necessarily leads to the inappropriate use of BAR, the misbalance of the diet in relation to the physiological needs and inefficiency of the industry. In turn, it requires the purchase and conservation of products for the period of use. Various chemical structures and structures of BAR during the storage process react differently and change qualitative indexes, which leads to a decrease in the productive activity of active substances. It was determined that the humidity of premixes varied within the limits of 12.0-13.0 %, which exceeded the normative, but was not critical, the highest acidity had premix with sulfuric acid salts (6.9 units), the least - premix with lysates (5.7 unit). According to the results of the study, positive qualitative responses were found for the presence of vitamins A, D and B2, macro- and micronutrients: potassium, magnesium, copper, zinc, cobalt, iodine. The above facts of changes in the properties of premixes in the process of storage must be taken into account when providing technological bases for feeding pigs in order to obtain high gains and the quality of manufactured products. Key words: premix, micro-and macro elements, combined fodders, fodder mixes, chelating compounds, feeding, using, pigs' livestock.
