Development of evaluation model effectiveness of modern technologies in crop production

Abstract

Effectiveness assessment of modern technologies and machines introduction is one of the most important economic objectives in agricultural production. The purpose of this paper is to develop a formalized effectiveness evaluation system of introduction of modern technologies and machines in crop production. This system is based on the use of modern software for creation of crop production process flow diagrams, business planning, and optimization of machines and technologies parameters. It is proposed to formulate the process of economic effectiveness evaluation of new technologies in crop production as a permanent operating three-stage indiscrete cyclic model for a particular industry, facility, district or region. In the first stage of calculations income and expenses staggered over a period of time and obtained through the new technologies or more modern tools are defined, using detailed process flow diagrams, fodder balance and other estimation forms. During the second stage project success criteria are determined by calculation of stability analysis and evaluation of feasibility and effectiveness of new technologies. Finally, in the third stage it is necessary to solve a task of introduced technologies parameters adaptation and optimization. The effectiveness evaluation system of introduction of modern technologies and machines in crop production, proposed in this paper, allows for quicker decision making regarding reasonability of replacing machines and technologies with new ones.

Revisiting weed infestation of agricultural lands from zones near utility poles

“…In accordance with research conducted in the Saratov region, 10 t/ha of applied manure, results in 0.8-1.0 mln. weeds seeds, which is only 4-5 times less than the seeding rate for winter wheat, for example (4.0-5.0 mln./ha) [10].…”

Economic aspects of biodiesel use in agricultural production

“…The cost of 1 kg of biodiesel from rapeseed oil is 27.14 rubles. According to the Ministry of Agriculture of the Russian Federation information, the average price in Russia for summer diesel fuel as of August 1, 2018 amounted to 37.019 rubles/ton, which can be seen from Table 1 [22].…”

“…To determine the biodiesel efficiency, using the program for calculating technological maps in crop production was used. As represented in Table 2, monthly diesel demand was determined [22]. Table 2.…”

Economic aspects of fruit production: a case study in Poland

“…The problem of finding the optimal cycle duration becomes involved when the cycle may be interrupted by stochastic events. Investigating the profitability of perennial crops under uncertain cycle duration induced by stochastic water regime (uncertain drought events), they show how the distribution of drought events induces a distribution on the cycle duration and, in turn, on the expected net present value (EV) of repeated crop cycles [20]. The analysis is applied to perennial crops grown in northern Israel and presents sensitivity to the drought hazard parameter and other weather and crop parameters.…”
