Abstract
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.
Highlights
The increase in soybean production in all growing zones is due to both the expansion of sown areas and, very importantly, the increase in its yield
There are no secondary measures in soybean cultivation technology
Its influence on the final result – yield, can be manifested to a greater or lesser extent, depending on the growing conditions.In this regard, there is a need to study the competitive relationship in soybean agrobiocenoses as a factor that can be regulated by elements of varietal cultivation technology
Summary
The increase in soybean production in all growing zones is due to both the expansion of sown areas and, very importantly, the increase in its yield. High soybean yields are possible only within the so-called soybean belt, outside of which its production without irrigation is risky, especially in the arid southeastern and southern regions. From the perspective, this strategic crop can be sown on a fairly large area of the right-bank and left-bank Forest-Steppe, Northern, Central and South-Western Steppe, Forest Steppe areas of Polissya and irrigated lands of the Southern Steppe. Its influence on the final result – yield, can be manifested to a greater or lesser extent, depending on the growing conditions.In this regard, there is a need to study the competitive relationship in soybean agrobiocenoses as a factor that can be regulated by elements of varietal cultivation technology. Most clustering algorithms are based on the use of heuristic methods, so their choice is to obtain the most useful result
