In the article agroecological factors of competitive bioorganic varietal technology of soybean cultivation which provides development of regulations of application of a complex of alternative types of fertilizers for their cultivation in the context of short-term and long-term action and basic superstructure of factor estimation of block. As part of joint research work of Vinnytsia National Agrarian University and the Institute of Bioenergy Crops and Sugar Beets of the National Academy of Agrarian Sciences of Ukraine, the authors were involved in research theme "Development of methods for improving the technology of growing legumes using biofertilizers, bacterial preparations, foliar fertilizers and physiologically active substances". To establish the reliability of yield data by analysis of variance, it was determined that LSD 0.05 for factor A in 2017 was 0.09 t/ha. The largest deviations of yield indicators to control among varieties were: variety Podilska 416 +0.41 t/ha, variety Chernivtsi 9 – 0.27 t/ha and variety Agate -0.66 t/ha, which exceeded the value of LSD 0.05 for the factor A (soybean variety) by +0.32, – 0.18 and – 0.57 t/ha, respectively.

This article provides an economic assessment of the elements of the technology for growing chickpea. The most effective aspects of the cultivation technology are highlighted, which provide the maximum increase in the productivity of chickpea plants and high economic efficiency. Assessing the economic efficiency of growing chickpeas and other agricultural crops in agricultural enterprises, first of all, it is necessary to determine the system of interrelated indicators that will objectively show its level. For this, they are often used both in value and in kind. According to the research results, the indicators of economic and energy efficiency of seed treatment before sowing and foliar dressing in the elements of chickpea cultivation technology, which were the object of study, were determined. The economic efficiency of growing chickpea grain in the Pravoberezhnaya forest-steppe was determined by the following indicators: the cost of production per 1 ha, the cost of 1 ton of grain, costs per 1 ha, net profit per hectare, and the level of profitability. During the calculation, the following research results were used: those that form the selling price – grain yield, yield increase, protein and fat content, and those that make up the cost of production – production costs. According to the exchange prices, the cost of chickpea grain is rather unstable and fluctuates in a wide range – from UAH 10,000 to UAH 30,000 per 1 ton. The cost of production from 1 hectare was set taking into account the price of chickpeas as of 31.12. 2019, which averaged UAH 20,000. When treating seeds before sowing with bioinoculant Rizoline + Rhizosave and two foliar feeding with micronutrient fertilizer, the legume yield of the Pegasus variety was high. net profit at the level of 17,815 rubles / ha with a profitability level of 155%, which is 68% more for control, for the Triumph variety – 15793 UAH / ha and 139%, which is 62% more for control. Considering the structure of costs, we can conclude that the maximum costs were respectively for the following categories of costs: for protective equipment – 21.5%, seeds – 34.9% and fuels and lubricants – 15.3%. Hence, a significant part of the costs falls on other costs, which include deductions for depreciation and repair non-current assets.

The problem of post-harvest winter rapeseed crops usage influencing siderate and green fodder, oil radish impacting siderate and forage, root and post-harvest remains of winter wheat, and also cattle manure (40 t/ha) influencing the weed littering of maize and grain under conditions of grain-cultivated crop rotation has been revealed by PS of NUBiP of Ukraine - Agronomic research station. It has been proved that the cleanest crops of maize on the typical low-humus and light-loamy black soils remained in the variants where its predecessors were oil radish and winter rape on green fertilizer. Compared to control (root and post-harvest remains of winter wheat), weed amount decreased by 54 and 37% accordingly. Oil radish had a sufficient toxic effect on weeds as it was evidenced by their weight which in this variant decreased under shelf cultivation by 72% and under chisel cultivation - by 61%. Higher yield of maize for both chisel and shelf cultivation was forming in variants with oil radish for siderate and green fodder. The yield increase was 0.3-1.0 under shelf cultivation and 0.7-1.2 t/ha under chisel cultivation.

In the Podillya area, the most promising for greening different objects is the Lupine perennis L. and Lupine Polyphyllus Lindl. For creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most appropriate are the varieties: Lulu-Russell, Minaret, Albus, Fireworks, which were well adapted to the growing conditions, were practically not affected by pests and diseases, were sufficiently resistant to environmental conditions. According to the flowering phase study, it was found that the highest flowering duration was observed in perennial lupine plants. In determining the suitability of the plants studied by us for their use in landscaping, their assessment of the complex of economic and biological indicators in accordance with the State Methodology of Variety Testing was carried out. Their high score on a set of criteria testifies to the prospect and suitability for cultivation in Podillia conditions, as well as the value for different uses: flower beds, ridges, mixboards, landscape type compositions and their smaller variants imitating natural groups.
