Modern agriculture Ukraine is at the stage from intensive costly to more efficient and less energy-intensive crops growing technologies based on the principles of all the processes minimization. An important measure to minimize primary tillage in addition to reducing its depth nowadays is the plowing replacement with less energy, labor and fuel-cost cultivation.

The highest rate of peas energy efficiency (1.50) was under the cultivation for sugar beet in the plowing and the lowest one (1.38) – without primary tillage. For winter wheat the highest rate (3.50) was under cultivation and the lowest (3, 16) – under plowing and without basic cultivation. For sugar beet the highest rate of  efficiency (5.22) under plowing and the lowest one (5.07) – under cultivation.

Soil tillage is one of the basic technology elements of peas, winter wheat and sugar beet growing. It is only efficient when well-chosen depending on soil and climatic conditions, meets the needs of cultivated crops and misaligned in scientifically grounded crop rotation. Tools and machines used for the relevant technological operations also play an important role in the process. Thus, the rational choice of the main cultivation is an important foundation for obtaining high and sustainable yields.

Under modern resource shortages Ukraine with its rich and fertile soil, continental and temperate humid climate, flat terrain and a high tillage percentage can take pride of place in the list of countries with stable agriculture. Positivity of this point is also reinforced with the geopolitical situation of Ukraine. It is located in Europe, adjacent to the economically developed countries, which are potential investors. Association with the EU makes it even more attractive in this regard. However, for those who want to invest money into the Ukrainian agricultural enterprises development, these positive characteristics are not enough.

Investors initially wish to receive an economic analysis of the case including the calculation of key indicators such as the size of variable and fixed costs, profit margins and business profits. Of course, all these calculations should be done  with current agricultural prices and their volatility is currently quite fast.

It is also advisable to analyze risks in the event of price extreme changes. In addition to significant savings in of seed crops growing cost, low or even zero agriculture practice, this situation contributes to the positive factors of influence on agricultural soils. Mechanized tillage reduction or complete removal from agricultural technologies helps provides soil protection it from erosion and fertility potential saving use.

However, these technologies reduce significantly the effectiveness of mechanical tillage in performing one of its important functions – pesticides free crops protection from pests. In this regard, these agricultural technologies in modern agriculture are characterized with excessive pesticides loading. To improve the land productivity, many farmers use fertilizers that only aggrevade the soil environment. Crops efficient protecting from pests and pesticides wide use causes problems in agricultural landscapes.

Using an alternative system of mechanical tillage to control the pests that would differ in fuel consumption and were economically and environmentally reasonable use of natural fertilizers subsidiary can contribute to solving this problem. That is why non-tillage and tillage basic cultivation is recommended in terms of careful land use system in crop rotation, featuring the best efficiency in controlling weeds control. The essence of the careful use is in the sequential change during rotation of soil tillage with plow under sugar beet every 4-5 years using measures od non-tillage cultivation – disking and flat loosening between the plowings. Thus, due to agropolitical situation in Ukraine, the importance of determining the cost-effectiveness of different measures of soil cultivation in growing peas, winter wheat and sugar beet is significant.

 Key words: peas, winter wheat, sugar beets, cultivation, basic tillage.
