Efficiency of Ethylene Application on Seed Potato Tubers

S.V. Maltsev

Abstract: Картофель (Solanum tuberosum L.)-одна из важнейших сельскохозяйственных культур в России. Клубни картофеля содержат белок, отличающийся высокой биологической ценностью, крахмал и необходимые для человека витамины. Известны различные способы повышения урожайности этой культуры, центральное место среди которых в настоящее время занимает внесение минеральных удобрений. Однако этот способ имеет свои ограничения, поскольку увеличение фона питания сопряжено с ухудшением потребительских и кулинарных показателей клубн… Show more

Currently, the search for B. thuringiensis strains to be used as biological control agents is based on their toxicity to insects in laboratory tests. At the same time, a number of strains of these bacteria are able to exist in symbiotic relationships with host plants, including being endophytes. The ability of B. thuringiensis strains to penetrate into the internal tissues of plants was evaluated by counting colony-forming units (CFU) of microorganisms 7 days after inoculation of sterile potato plants in test tubes; insecticidal activity was tested on larvae of the 3rd age obtained from overwintered adults of the Colorado beetle collected from fields in the Chishminsky and Iglinsky districts of Bashkortostan. It was shown that the strain of B. thuringiensis B-5351, which inhabits the surface (50.01 ± 8.10 CFU × 105/g) and internal tissues (38.92 ± 9.62 CFU × 105/g) of plant shoots, but has less insecticidal activity than the strain B. thuringiensis B-5689, which exhibits high insecticidal activity and colonizes mainly plant roots (25.37 ± 3.82 CFU × 105/g), reduced colonization of potato crops by the Colorado potato beetle, and also increased the yield of tubers in a 2-year experiment (2020–2021). Under the influence of B. thuringiensis B-5351, a decrease in the number of larvae of early age was observed, in contrast to B. thuringiensis B-5689, which caused longer metamorphosis processes. Apparently, the effect of B. thuringiensis B-5351 was the death of insects. It is important that processing B. thuringiensis B-5351 contributed to a significant decrease in the number of late-instar larvae on crops treated with this strain, as well as the degree of defoliation of plants by the pest, which was not observed with the action of B. thuringiensis B-5689. On plots treated with B. thuringiensis B-5351, the yield of commercial tubers and the total yield increased. A method is proposed for studying the endophytic potential of strains in relation to the terrestrial part of plants to search for biocontrol agents as a basis for creating algorithms for constructing microbiomes in agrocenoses.

Potato is grown almost everywhere, mainly in areas with a temperate climate and the most favorable weather conditions for the growth and development of this crop. Various varieties of potatoes are also grown throughout the Astrakhan region, but the very harsh arid climate of natural conditions, as well as soils with low humus content, significantly affect the productivity of this crop.The use of improved agricultural technologies for cultivating various varieties of early potato is today a very important area in vegetable growing in the Lower Volga region. In this connection the search for modern resource-saving agrotechnological methods for cultivating early potatoes, which would contribute to high yields at lower production costs, is very relevant.Therefore, the main goal of the research is to study the features of early potato yield formation when using pre-planting soaking of tubers using Azotovit, Phosphatovit and Baykam EM 1 preparations on the background of various irrigation rates of 4600 m3/ha and 5200 m3/ha. The studies were carried out on an irrigated land use plot of the FSBSI «PAFSC RAS» in the period from 2019 to 2021. In the experiment generally accepted agricultural technology was used in accordance with zonal recommendations for cultivating early potato in the Lower Volga region.Relevant studies and measurements were carried out in accordance with the requirements of the field experiment methodology and research methods for potato crops.Experimental studies established that over the period of a three-year study, the minimum water consumption coefficient of 110.05 m3/t was obtained in the option with an irrigation rate of 5200 m3/ ha, in the option with treatment of tubers before planting in Azotovit preparation, while this option turned out to be the most profitable in studying. The yield in this option was 56.0 t/ha with a total cost of 489.1 thousand rubles. The cost was equal to 8.7 thousand rubles per 1 ton, net income 630.9 thousand rubles per 1 hectare. With such indicators, production profitability amounted to 129.0%.
