Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

In this article approaches to search for reserves of decrease in cost of agricultural production are considered. The methods of cost calculation of dairy cattle breeding products used at the studied enter-prise are analysed, short characteristic of the standard method offered by the Ministry of Agriculture is given, and calculations of alternative options are also carried out. Today creation of accounting of a production unit is very important so that not only weight units must be considered in it, but also the quali-tative structure of products must be reflected. Definition of qualitative characteristics and technological properties by production of milk which depend on use purposes can be an example. The raw materials consumption on a unit of production and its quality and also firmness of storage depends on technologi-cal properties of milk. At calculation of prime cost taking into account qualitative characteristics for cal-culation milk in terms of basic fat content undertakes. The method of calculation of prime cost consider-ing qualitative characteristics is the most expedient as prime cost of 1 c of milk unlike the operating tech-nique is lower. In the article analytical methods of reserves calculation for decrease in prime cost taking into account various factors are proved. The revealed reserves will allow an enterprise to expand its in-vestment opportunities in the future, they will give an additional incentive of modernization of the worn-out machinery and equipment in branches of agriculture.

A study was undertaken in collaboration with eight Krishi Vigyan Kendras (KVKs) and five Learning and Experience based Advisor (LEAD) farmers were selected by each KVK, employing socio-metric technique. Hence, data were solicited from 40 LEAD farmers from eight districts who were trained by KVKs. Role of KVKs were determined based on their Index Value (IV). Study reveals that KVKs played an important role in skill development of LEAD farmers through organisation of need based and skill-oriented trainings (IV=62) followed by front-line demonstrations on location specific agricultural technologies at farmers’ fields (IV=59.42), and developing linkages between LEAD and fellow farmers (IV=58.33). Key determinants accountable for enhancing effectiveness of this model were enhanced technology adoption (IV=60.13) followed by enhanced agricultural production (IV=57.48) and productivity (IV=57.10). Study reveals that one LEAD farmer adopted 5 agricultural technologies from KVKs. Further, fellow farmers adopted 2 agricultural technologies from LEAD farmers. Hence, it was concluded that this approach may play a significant role in complementing Indian public extension system through reducing cost and coverage of more farm families. This model needs community as well as government support for sustainability and its scalability.

Creating and maintaining a microclimate in animal housing is an energy-intensive technological process that consumes up to 70 percent of the thermal energy consumed on cattle farms. Improving heating and ventilation systems aimed at reducing energy consumption is an urgent task. (Research purpose) The research purpose is to analyze the theoretical models for calculating air curtains and evaluate the possibility of their use for agricultural production facilities and to identify promising directions in the design solutions for thermal air curtains aimed at rural consumers. (Materials and methods) The article considers the theoretical justification and calculation of air curtains. The authors studied the physical model of interaction of air jets in openings, which serves as the basis for mathematical calculation of air curtains in engineering practice. The article describes the features of using the models for calculating air curtains for agricultural objects and the energy parameters of the curtains depending on the design characteristics and external environmental factors. (Results and discussion) The effect of the air curtain on the energy characteristics of the room has been studied. It was found that it is necessary to determine the type of air curtain that is optimally suitable for protecting the gate opening, with or without heating the air curtain. Authors have found that the engineering methods of calculation are based on different experimental data, which leads to a discrepancy in the results of evaluating the effectiveness of the designed curtain, overestimating its energy intensity and power. The calculation of heat curtains, operating modes should be carried out taking into account the variable effects of external physical factors, the equipment should correspond to a specific room. (Conclusions) The use of air curtains reduces or eliminates the penetration of external cold air into the room through the openings of external gates, requires a smaller volume of air supplied by the curtain, compared to the mass of the incoming air flow.

The authors focus on the process of potash ore production by a mechanized method. They show that currently there are no approved procedures for assessing the performance of heading-and-winning machines operating in the conditions of potash mines. This causes difficulties in determining the field of application of heading-and-winning machines, complicates the search for implicit technical solutions for the modernisation of existing models of mining units, prohibits real-time monitoring of the stability of stope-based technological processes and makes it difficult to assess the performance of the services concerning mining enterprises. The work represents an aggregate assessment of the performance of heading-and-winning machines for potash mines by determining complex indicators describing the technological and technical levels of organising the work in stopes. Such indicators are the coefficients of productivity and energy efficiency, respectively. Experimental studies have been carried out in the conditions of the potash mine of the Verkhnekamskoye potassium-magnesium salt deposit to assess the performance of the latest and most productive Ural-20R heading-and-winning machines manufactured in Russia. Using the above methodological approaches, this paper shows that the unsatisfactory technological performance of the studied machine is due to the low productivity of the mine district transport. The average productivity coefficient was 0.29. At the same time, high values of the energy efficiency coefficient show that the productivity of the machine is on par with design conditions.

The article is devoted to substantiating the prospects for increasing the marginal volumes of agricultural production for export in the next four years. Two scenarios of such production are considered: 1) expansion and 2) intensification of the use of land resources. As part of the development of the first scenario, an analysis of the distribution of unused agricultural land, including arable land, by federal districts was carried out. Also, based on the forecast of the introduction of additional annual volumes of acreage in the subjects of the Federation, the calculation of additional volumes of agricultural production, which can be expected in the next four years, was carried out. The analysis of data on the increase in the yield of export-oriented crops over the past five years has been carried out, in the framework of the second scenario, the calculation of the projected additional yield due to the intensification of agriculture is presented. The results of the study indicate that the intensification of agriculture will have the greatest impact on the growth of production and export of agricultural products in the near future.
