From an economic point of view, efficiency implies the use of resources, of any kind, at maximum efficiency, or else the relation between effect and effort is over unit. In any kind of activity economic efficiency is the basis for its start. In the present paper, the level of economic efficiency for rape crops will be determined, according to two technological systems: conventional and organic. The revenue structure, and especially the expenditure, will be found in the income and expenditure budget of the culture. We will compare the value of production, production costs, but also yield or rate of return. In the continuation of the study, a set of indicators of economic efficiency will be calculated for each crop system, which will be subjected to a mirror analysis, to determine the feasibility of rapeseed crops as accurately as possible. Finally, the results will be presented, the profitability of the crop according to the system, the level of the profit and the recommendations regarding the future way of growing the rapeseed.

The processes of optimization of the production plan according to certain criteria by modeling were investigated. Achieving effective results directly depends on the optimal production plan. The most important thing in determining the optimal production plan is the choice of modeling criteria. For the most part, the quality of decisions is characterized not by one but by many incomparable criteria. Therefore, it is necessary to make decisions based not on one but on many criteria. This so-called multi-objective optimization problem. For solving such problems is widely used mathematical methods. Mathematical approach can be used to solve problems in any particular activity as mathematics abstracted from specific features characteristic of a particular solution. Therefore, from the point of view of mathematics, the optimal result can be obtained with various established criteria, but from the economic point of view it is important to choose the ones that are of decisive importance. That is, their weight is important for the consumer when making a purchase decision, and for the manufacturer – in terms of production capabilities of certain types and results (production efficiency). The basis of the operation of any enterprise is a production program (production and sales plan). The main task of the production plan is to meet the needs of consumers in high-quality products, which are produced with the best use of resources, on the one hand, and the enterprise to get the maximum profit, on the other. With this in mind, a two-criteria optimization model that allows to make a production plan was proposed. The plan ensures that products are produced with the best use of available resources and at the same time ensures maximum quality of manufactured products and maximum profit from sales of these products. The solution of the problem with two objective functions and linear constraints is achieved by step-by-step solution of the proposed mathematical model of optimization of the production plan using the method of sequential restrictions. The simplex method was also used. An example shows an algorithm for solving the optimization problem.

Cargo Transportation

Background: Currently, the car, water, railway, air and pipe transports are used for cargo and goods transportation. Each kind of cargo transport has its own specific competitive advantages that provide its most effective application at various stages of logistics chain. The economic efficiency of cargo transportation influences the overall economic efficiency, in particular, the gross domestic product. The quality of economic growth as applied to transport branch and its input to the national economy is relevant, since with the current organisation of different transport modes interaction, there are still high transaction costs. Aim: Study of influence of various modes of transport, including maglev transport, on the economy and economic growth. Methods: Theoretical and empirical. The paper considers the influence of various modes of transport, that operate in the cargo transport sphere, on the countrys economy. The comparison of existing modes of transport with the maglev transport from the point of view of desired effects is made. Results: The maglev transport possesses new properties and advantages, which makes it possible to view is as viable and able to provide a qualitative economic growth and resource-based economy if realised. Conclusion: The most efficient use of resources, the consumption of which should at least not increase and at most decrease, is achieved with the introduction of maglev transport into the transport system, as its economic properties already now excel those of the majority of other types of transport. It is obvious, as to the experts, that in transition to resource-based economy the maglev transport will be major transport for both cargo and passenger transit.

Microalgae have been recognized as powerful phototrophic cell-factories whose applications range from biomass production for food and feed purposes to the production of high-value products and biofuels. Microalgae have been considered a source of functional ingredients, such as polyunsaturated fatty acids, polysaccharides, essential minerals, vitamins and bioactive peptides that can have positive effects on human and animal health. Besides having high nutritional value due to the high percentage of proteins in their composition, microalgae generate high-value products, such as pigments, polysaccharides, bio-hydrogen, and even bio-polyesters with plastic-like properties. Algal biomass that remains after product recovery can be used as forage, biofertilizer or feedstock for biogas production. This step in overall algal production is important from an economic point of view due to the reduction in production costs. This paper presents the detailed study of the biotechnologically most important microalgae strains, and the design principles of photobioreactors for their cultivation. In addition, the main existing and potential high-value products derivable from microalgae, as well as utilization of microalgae for phytoremediation and biogas production, were reviewed.

ABSTRACT The use of pre-sprouted seedlings in the implantation of sugarcane crops not only reduces the establishment period and production costs, but also has other advantages, such as a lesser requirement of propagules (stems) and greater phytosanitary control of the seedlings, when compared to conventional planting. Commercial substrates are also expensive and their use increases the cost of seedlings. This study aimed to evaluate the quality of sugarcane pre-sprouted seedlings grown on substrates with different proportions of decomposed babassu palm stem (DBPS), as well as to recommend the substrate formulation that provides the most favorable environment for the growth and development of sugarcane pre-sprouted seedlings. For preparation of the substrate (S), DBPS and soil were used in the following proportions: S1: 0 % of DBPS + 100 % of soil; S2: 20 % of DBPS + 80 % of soil; S3: 40 % of DBPS + 60 % of soil; S4: 60 % of DBPS + 40 % of soil; S5: 80 % of DBPS + 20 % of soil; S6: 100 % of DBPS + 0 % of soil. The use of S2 and S3 considerably improved the seedling quality parameters, such as sprout diameter and length, number of leaves and total, shoot and root dry mass. However, from an economic point of view, S2 is recommended for use.

The aim of this study was to estimate the production cost and economic indicators associated with the production and sales of fruits from 20 custard apple progenies during the initial five harvests, in order to identify the harvest season from which custard apple exploitation becomes profitable, as well as the most promising progenies from an economic point of view. The fruit yield data upon which the present work was based were obtained during the period from 2001 to 2005, in an experiment that evaluated 20 custard apple half-sibling progenies, under sprinkler irrigation. The progenies were evaluated in a random block design with five replicates and plots consisting of four plants each. The exploitation of custard apple progenies only showed to be a profitable agribusiness after the fourth year. Before that, only A3 and A4 progenies in the second year, and P3 and P11 in the third year provided profitable incomes. Considering the methodological assumptions imposed concerning the time period analysis and the prices as of July 2007, the most important profitability indicators (operating profit, return index and equilibrium price) evidenced that the A4 progeny is the most recommended, although other progenies are also highlighted, such as FJ1 and FJ2. As already discussed, the progenies showing the highest average yields of five harvests are not always the most economically recommendable ones.

SummaryNitrogen (N) fertilization of Kentucky dark fire-cured tobacco can be used to increase weight of high quality cured leaves for cigar manufacture. We conducted field experiments at 11 different locations in the province of Benevento (Southern Italy) where the following four N treatments were compared: 1) unfertilized control (N0); 2) a site-specific N rate, calculated by a N fertilization plan (NFP) based on physical and chemical soil characteristics, which ranged between 113 and 145 kg N ha−1; 3) 200 kg N ha−1 (rate commonly used by farmers, N200); 4) 100 kg N ha−1 (half of the rate commonly used by farmers, N100). Yields of the following five commercial quality categories of cured leaves were measured: i) wrappers, ii) heavy filler (Fh), iii) light filler (Fl), iv) heavy shredded (Sh) and v) light shredded (Sl). Fh cured products of B1, B4, B6 and B10 locations were analyzed for: total alkaloids, reducing sugars, chlorides, total N (Kjeldahl), ammonium-N (NH4-N), nitrate-N (NO3-N), and tobacco specific nitrosamines (TSNA). Color parameters: Lightness (L), Chroma (C) and Hue (H) were determined on five cured leaves / plot of both Fh and Fl types at B1, B2, B3, B6, B8 and B10. A blind evaluation of cured leaves collected across locations was conducted by a panel test who considered the main basic characteristics of cured leaves (stalk position, leaf structure, texture, etc.). The total yield of cured products increased with fertilization across locations, up to NFP treatment, without any statistically significant increase at N200 treatment. Fertilization increased yield of wrappers at B1 up to NFP treatment (113.5 kg N ha−1), without any significant increase at N200 treatment. Yield of light filler product was positively influenced by fertilization up to the maximum dose only in 5 out of 11 locations. Total alkaloids significantly increased with increasing fertilization up to 100 kg N ha−1 without any significant changes at higher N rate. Fertilization hardly increased L and C of Fl leaves, which appeared light-brown but brilliant-colored. There was a reduction in the H value of Fh products which indicated a darker tone of those leaves with respect to Fl. Increasing N rate affected production costs more than revenues. According to agronomic results, in most locations the best results in terms of net revenues were obtained by NFP treatment. Considering that N rates above the NFP would disqualify growers from the economic aids provided by EU agrienvironmental measures, by economic point of view the NFP treatment would be recommended over the current grower standard (N200).
