“…The content of humus is 0.6-0.95%, total nitrogen is 0.12-0.15%, mobile phosphorus is from 18.0 to 48.3 mg/kg, exchangeable potassium is 120-180 mg/kg [6,7]. Therefore, in order to provide a stable harvest of fruits, plants need additional nutrition [8]. The cultivation of watermelon on a layer of perennial grasses (Agropyron pectiniforme), as well as the use of systems of mineral fertilizers, are known to give a high effect in increasing the productivity of watermelon crops [9].…”

Modern agricultural technologies require new approaches allowing to increase yields and produce fruits with high properties. The aim of the research was to assess the effect of foliar processing of watermelon plants with growth regulator Vigor Forte in various doses and combinations with liquid fertilizers on growth, development, yield and biochemical traits of fruits. The research was carried out in 2018-2020 on Bykovskaya Melon Breeding Experimental Station - a branch of the FSBSI “Federal Scientific Centre for Vegetable Growing” (Volgograd region). The treatment of plants was carried out twice, the first one was at the beginning of branch forming, the second one was after 10-12 days. The following rates of fertilizers were used: Vigor Forte - 25 g/ha and 50 g/ha; Agrovin Universal, Agrovin Profi, and NPK complex - 500 g/ha. Consumption of working solution was 200 l/ha. The object of research was an early cultivar of watermelon Triumph. Untreated plants were accepted for control. Treatment of watermelon plants with Vigor Forte combined with Agrovin Universal or Agrovin Pro fertilizers increased yield by 36.7 - 77.9%. There were no significant changes in the biochemical traits of the fruits. The amount of nitrates did not exceed the MPC (60 mg/kg).

RelevanceThe relevance of the bioenergy assessment follows from the requirements of modern production: energy saving per unit of output.MethodsThe article presents the data of bioenergy evaluation of the use of table predecessors, types of fertilizers and growth regulators in the technology of watermelon cultivation.ResultsThe results of studies have shown that from the energy point of view, the proposed methods of cultivation of watermelon, are effective, because the coefficient of energy efficiency in all the studied variants is more than one. Studies have revealed the advantage of a layer of perennial grasses as a precursor to watermelon: CEE – 2.55 at its values according to the predecessor of winter rye – 1.70. The use of mineral fertilizers dose N60P90K60 in rain conditions leads to a significant increase in energy consumption of commercial products, 1.7 times more in the formation of perennial grasses and 1.3 times more than the predecessor of winter rye. A decrease in the CEE and an increase in the cost of total energy and energy intensity of 1 ton of products using manure 27 t / ha in relation to mineral fertilizers. Comparative energy analysis showed high efficiency of using water-soluble fertilizers and growth regulators for soaking seeds and processing of vegetating plants in watermelon cultivation. The use of these agricultural practices can reduce the energy costs of total energy by 70-79% compared with the introduction of mineral fertilizers dose N60P90K60, with an increase in the energy efficiency coefficient from 1.54 to 2.68-2.77. As shown by calculations from the energy point of view, the best was the reception of cultivation of watermelon table using for seed soaking and processing plants in vegetation water-soluble fertilizer master special with the addition of growth regulator megapol, the value of the EPS was amounted to 2.99, which is 7.9% and 11.5% more in comparison with potassium Humate and Ribav-extra, respectively.

The effectiveness of the use of new foliar fertilizers and growth regulators for vegetative plants of watermelon in dry-steppe conditions of the Volgograd region has been studied. It was found that the direct supply of nutrients to plants contributed to the progression of growth processes. The maximum plant growth was noted in the variant Vigor Forte + Agrovin Profi + NPK complex, where the excess of the number of lashes to the control was 115%, the length of lashes - 346%. Good development of plants increases their resistance to adverse weather conditions and increases the ability of plants to bear fruit. The maximum effect in increasing the yield was achieved when using Vigor Forte growth regulator in combination with foliar fertilizers - 20.4 t/ha, which is 1.7 times more than the basic technology. It has been determined that the use of water-soluble fertilizers and growth regulators in the cultivation of watermelon makes it possible to obtain high quality products with an amount of nitrates less than the maximum permissible concentration (MPC) - 60 mg/kg. The increase in economic indicators with the use of new foliar fertilizers and growth regulators relative to standard technology ranged from 16,8 to 72,3%.
