Solubility of iron is limited in calcareous soil although it is one of the most common elements in earth’s crust. Therefore, plants growing in this kind of soil are constantly exposed to the stress of iron deficiency. When untreated, iron deficiency restricts agricultural production because one third of the agricultural land in the world is made up of this type of soil. Different iron fertilizers are used in the treatment of iron deficiency observed in plants. However, the use of these fertilizers increases production costs. In order to reduce the cost, plants must be able to use the most effective way to extract iron from the soil. For this reason, it is necessary to first examine how the plants take iron into roots from the soil. It has been discovered that during the last three decades, different plant groups used three different iron uptake mechanisms. The purpose of this review is to talk about the transporters responsible for the uptake of iron into the root, and the current developments about these transporters.

Abstract The article presents a study which concerns the development of production of niche crops in conjunction with the development of animal husbandry. In particular, the expedience of introducing such a niche crop as horse beans (fodder) into the diet of pigs is substantiated on the example of a specific enterprise, typical for the agricultural sector of Ukraine. It is estimated that this will increase the efficiency of swine breeding product output and, indirectly, the efficiency of growing beans. Beside this, at the request of today regarding of the need to reduce the cost of agricultural production, a possible increase in economic efficiency of horse bean production at the expense of resources in accordance with the existing Technological maps of crops was simulated. It is estimated that by laying down production costs according to the technological map, it is possible to obtain increased yields, increased profits and profitability. It is substantiated that together the obtained results can be considered as a possible tool of balanced and complex development of agricultural production in the context of food security in the world.

Background The World Health Report (2006) by the World Health Organization conveys that a significant increase is needed in global health care resourcing to meet the current and future demand for health professionals. Electronic learning (e-Learning) presents a possible opportunity to change and optimize training by providing a scalable means for instruction, thus reducing the costs for training health professionals and providing patient education. Research literature often suggests that a benefit of e-Learning is its cost-effectiveness compared with face-to-face instruction, yet there is limited evidence with respect to the comparison of design and production costs with other forms of instruction or the establishment of standards pertaining to budgeting for these costs. Objective To determine the potential cost favorability of e-Learning in contrast to other forms of learning, there must first be an understanding of the components and elements for building an e-Learning course. Without first taking this step, studies lack the essential financial accounting rigor for course planning and have an inconsistent basis for comparison. This study aimed to (1) establish standard ingredients for the cost of e-Learning course production and (2) determine the variance instructional design has on the production costs of e-Learning courses. Methods This study made use of a cross-case method among 3 case studies using mixed methods, including horizontal budget variance calculation and qualitative interpretation of responses from course designers for budget variance using total quality management themes. The different implementation-specific aspects of these cases were used to establish common principles in the composition of budgets in the production and delivery of an applied health professional e-Learning course. Results A total of 2 case studies reported significant negative budget variances caused by issues surrounding underreporting of personnel costs, inaccurate resource task estimation, lack of contingency planning, challenges in third-party resource management, and the need to update health-related materials that became outdated during course production. The third study reported a positive budget variance because of the cost efficiency derived from previous implementation, the strong working relationship of the course project team, and the use of iterative project management methods. Conclusions This research suggests that the delivery costs of an e-Learning course could be underestimated or underreported and identifies factors that could be used to better control budgets. Through consistent management of factors affecting the cost of course production, further research could be undertaken using standard economic evaluation methods to evaluate the advantages of using e-Learning.

Worldwide, there are many Insect-Resistant Genetically Modified Crops (IR-GMCs) planted with the purpose of controlling their many insect pests. All genetically modified (GM) plants have to pass through a regulatory system before being commercialized. In the case of Argentina, specific information is requested for these particular GM crops. This review will cover all the data required of IR-GMCs in Argentina in relation to insect resistance to the insecticidal products expressed (the most common in Argentina: Bt proteins) as well as the current situation of Bt crops in Argentina. From earliest times, man has used living organisms and their products in order to produce goods and services to meet their basic needs. For instance, man has modified, first unconsciously and then intentionally, the genome of many commodities so as to obtain improved cultivars. Taking the example of maize, its ancestor, the teocintle, is different in appearance (compared to the maize we consume nowadays). The selection process, which has taken place over many years, introduced improvement in many phenotypic characteristics such as the size of the grain. This example illustrates what is considered "Traditional Agrobiotechnology" or 'Traditional Plant Breeding'. The advent of Genetic Engineering and Molecular Biology in the second half of the 20th century has opened the door to "Modern Agrobiotechnology". The increase of agricultural production worldwide is demanded by a constantly increasing global population. As result of this, man has taken advantage of this valued tool so as to produce more in the same amount of land in a sustainable and cost-effective way. Thus different kinds of crops have been genetically engineered around the world with beneficial traits like insect resistance, herbicide tolerance and nutritional improvement. Worldwide, insects are a major cause of crop damage and yield loss, often requiring farmers to make multiple applications of chemical insecticides to control pests. For that reason, the commercial release of IR-GMCs also called Insect-resistant biotech crops has been an important contribution from Modern Agrobiotechnology to increase the global agricultural production. By the end of 2016, the cultivated area under GM crops reached 185.1 million hectares. 53% of that area was planted with IR-GMCs (single and stacked events with tolerance to herbicides). The commercialized genetically engineering crops that have protection against insect damage around the world are cotton, maize, soybean, potato, rice, tomato, eggplant and poplar. Insect-resistant biotech crops provide a number of benefits, such as a reduction in the use of chemical insecticides, improvement in yield, quality and lower production costs compared to the conventional crops.

In modern conditions agricultural enterprises activity is affected by the organization of management, which provides economic independence of business entities, their competitiveness and return on production costs. In turn, the effectiveness of management is affected by the efficiency and adequacy of accounting information, which is received by the administrative and management personnel. The term of calculation, due to its versatility, is of a great interest on the part of scholars and practitioners. On the one hand, calculation is represented as a set of techniques of analytical accounting of expenses for production and calculation of the cost of production, on the other hand, it is presented as a component of cost accounting. All this shows, that this term includes various aspects, related to the development and acquisition of information about the production process, its costs and results. This information is undoubtedly important with the development of production activities of agricultural organization. Despite the rather close attention to the issues of cost accounting and calculation of the cost of agricultural production, there is a need to study in detail and further improvement of cost accounting and calculation of the cost of agricultural production in the management system of agricultural organization. The paper deals with the selection of objects for accounting of production, calculation facilities and calculation units in horse breeding. A method of calculating the cost of horse-breeding products was also provided. Simultaneous use of modern information technology will significantly reduce labor costs, compared to manual processing of accounting information

Climate change is responsible for the negative effects in human life causing a decrease in agricultural products, biodiversity, soil fertility, and forest areas. In contrast, climate change increases plant diseases and pests, the cost of agricultural production and risk in food security. This study aims to determine whether climate change is a phenomenon via the analysis of the perceptions of the farmers in the Mersin province conducted over 251 questionnaires. Farmers primarily perceive climate change over production costs and the reduction in yield. Moreover, they are highly aware of its relation to natural events such as floods, drought, and storms. Nevertheless, inappropriate agricultural practices also lead to the negative consequences caused by climate change. In this respect, this study revealed that farmers with high cooperative partnerships and experience perceived climate change significantly.

The biodiversity loss is one of the biggest environmental problems in the world. The objective of this paper is to present some nature conservation practices on agricultural land. Farmlands play a significant role to preserve biodiversity because some highly protected species can only find their needs on agricultural land. The Biodiversity Strategy of the European Union (2010-2020) creates new directives to reduce biodiversity loss, preserve and improve diversity, especially on agricultural land. Furthermore the importance of this subject is that the share of farmland in Hungary is much higher (57%) than in the EU-27 on average (42%). The loss of agricultural land and the increase of land abandonment cause intensification of agricultural production leading to the loss of biodiversity.

The cost of production is one of the most important indicators of the economic efficiency of agricultural production. It shows how much the production of agricultural products to a particular enterprise costs. The cost price reflects the qualitative aspect of the economic activities of enterprises: the efficiency of using production resources, the state of technology and organization of production, the introduction of science and advanced experience, the level of economic management. The cost of production is necessary to justify the rational allocation and specialization of agricultural production, to determine its economic efficiency, to establish the level of prices for agricultural products. The purpose of this article is to show ways to reduce the cost of agricultural products, which is one of the most important issues in Uzbekistan. This article discusses ways to reduce the cost of production in agriculture and suggests ways to reduce costs in order to improve efficiency in the production of agricultural products.
