Water consumption of sunflower, depending on the use of biological products when grown in the Southern Steppe of Ukraine
Journal Title: Наукові горизонти. Scientific Horizons - Year 2018, Vol 70, Issue 7
Abstract
The article analyzes the peculiarities of growing and water consumption of sunflower in Ukraine in the zone of the arid Southern Steppe. Data on areas, yields and water consumption characteristics of sunflower culture are presented. The results of studies conducted in 2016-2017 are presented. In the conditions of the UNNA on the chernozem southern chernozem on the influence of elements of the technology of cultivation, namely, the improvement of nutrition by applying biological products to yield and water consumption of sunflower in the Southern Steppe of Ukraine. It is determined that, on average, over two years of research, the increment in the yield of sunflower seeds, depending on the variants, ranged from 8.8 to 50.2%. In addition to increasing the yield of sunflower seeds under the influence of foliar dressing by biological preparations, on the contrary, the water consumption coefficient decreased, that is, the moisture that plants spend on the formation of a unit of yield is used more efficiently. On average, for two years of cultivation, the water consumption factor in the control was 1320.4 m3 / t and this was the largest indicator in the experiment, and the minimum was for conducting two fertilizing in 3-4 pairs of leaves and budding the fresh energy - 873.4 m3 / t or decreased by 51.2%. The same coefficient of water consumption was for the use of fresh biomedical products in the same phases for the same phases of fresh energy and fresh Florida - 874.1 m3 / t (a decrease of 51.1%). Based on the analysis, ways to increase sunflower productivity have been developed, approaches to solving urgent problems, in particular effective use of moisture, have been proposed, and strategic options for increasing its yield based on resource saving have been identified.
