The article considers the problems of energy supply and rational use of energy in the production of agricultural products in the conditions of market economy
The article considers data obtained in long-term stationary experiment in Kuban state agrarian University, which was started in 1991 for old irrigated leached black soil of the central zone of the Krasnodar region. Studies were conducted in two rotations of seven-field grassy-grain-row crop rotation. The duration of irrigation - more than 30 years. It is established that long-term irrigation by sprinkling led to the soil over-compaction in both arable and subsurface layers. In the arable layer of 0-30 cm density of 0.14-0.17 g/cm3 exceeds the maximum allowable. We have noticed a sharp decrease in humus in the arable layer to 2.46-2.67 per cent. The weak acidification of the active root layer was noted, salt PH 5.0-5.3. In the soil-absorbing complex, the content of calcium decreases. It was found that the productivity of crops cultivated in the rotation of two rotations was greatly influenced by the system of basic soil treatment. In the first rotation, the decrease in productivity of cultivated crops against the background of the surface treatment system amounted to an average of 4.2% compared with deep: subsurface tillage and moldboard. In the second rotation after 14 years against the background of shallow surface treatment crop rotation productivity decreased by 11.2 %. The dependence of the fertilizer system and crop yield on the background of different main soil tillage is established. When using the mineral fertilizer system, the decrease in crop productivity, while minimizing the main tillage in the second rotation was 15.2%, and against the background of the organic fertilizer system by 12.7%. The deep sub-soil treatment provided an increase in the productivity of old irrigated leached black soil in the second rotation against organic fertilizers by 3.6%.
Thus, the organic system of fertilizers on the background of deep main soil tillage allows to obtain crop yields in the framework of grassy-grain-row crop rotation on wetlands degraded old-irrigated lands is not lower than using high doses of mineral fertilizers
The article presents the results of bio-energetic and
economic evaluation of alternative technologies for
cultivation of winter wheat, developed in long-term
stationary experiments at Kuban State Agrarian
University. We study the effect of four factors on the
productivity of winter wheat, quality of soil, fertilizers
system, systems of soil tillage and systems of
protection. We have processed the data for 7
technologies in two rotations of 11 fields grain-grass
crop rotation in the Central part of the Krasnodar
region on leached black soil of plains of the
agricultural landscape. We have established, in the
first crop rotation, on the example of varieties of
Batyka and Krasnodarskaya 99, that there were
changes in costs of production, net profit and the cost
of 1 centner of grain, depending on the technology,
and the comparative evaluation of bioenergy impact of
alternative technologies of winter wheat cultivation to
consumption energy costs total energy. We have
calculated ratio net of efficiency depending on the
technology of cultivation of winter wheat. On the basis
of economic and bioenergetic calculations for farms
with different level of economy we have proposed an
alternative technology: for economically strong,
economically average, economically weak farms and
for farms located in protected areas where is
prohibited the use of chemicals. Thus, producers have a choice of alternative technologies of winter wheat,
which will contribute to maximizing profits and
obtaining competitive products
The article deals with the economic evaluation of seven studied alternative technologies for cultivation of winter wheat and corn in conditions of the pinned low-lands agro-landscapes of the Central zone of the Kras-nodar region. The high efficiency of the reclamation technology of cultivation has been revealed
The article is devoted to analysis of integrated industrial systems activity and creation of production line model of integrated grain-processing industrial system. The scheme of material-financial streams in the integrated industrial system of wheat grain production and processing is offered.
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches
of agriculture, economics of agricultural enterprises
in whole as well. Models and methods of decision taking process improvement in plant growing were considered in the paper.
The article presents the principles of the development
of mobile applications for the operating system called
iOS. Details were considered for popular patterns and
their features
Prognosis of industrial results of some or other agro technologies application and support of decision taking by choice of such varieties of grains and rational agro
technologies for their cultivation, which with
most probability would show the given desirable
industrial result in advance are cited in the article.
Demand to the method of statement of problem is substantiated and degree of known methods
correspondence to these demands is determined,
the most available method of problem decision is
chosen by the substantiated criteria, the essence of chosen problem and the method of its application to decide the problem in view, including synthesis of semantic informational model and evaluation of its adequacy are described in brief as well.
