Polymer hydrogels (superabsorbent polymer) are a water-retaining, biodegradable amorphous polymer that can absorb and retain water at least 400 times its original weight, and gradually gives away at least 95% of the accumulated water available for absorption by plants. The purpose of the research is to study the possibility of using resource-saving technology for the production of carrots and beets on a profiled surface in the absence of irrigation using polymer agrogels. The research was carried out in 2017–2019 at the ARRIVG – branch of FSBSI FSVC. The soils of the experimental site belong to the type of alluvial meadow saturated soils. The object of research is carrots in non-irrigated conditions of the Moskvoretsky floodplain. The work was carried out with the Royal Forto carrot variety. On carrot crops, the domestic polymer acrylamide moisture-absorbing brand AK-639 was used, which should be used when cutting combs in an amount of 17.5 g/m2 to a depth of 5–10 cm. Experience options: 1) control (without application), 2) treatment with polyacrylamide (17.5 g/m2). The area of the experiment is 0.07 ha, plots – 84 m2, accounting plots – 42 m2, the repetition is threefold. The seeds of the sown crops corresponded to GOST 32592–2013 «Seeds of vegetable, melon crops, fodder root crops and fodder cabbage. Varietal and sowing qualities. General technical conditions». When conducting research, we were guided by generally accepted methods. The addition of moisture-absorbing polymers to the soil delays the evaporation of water and outflow due to gravity, thereby making water available to plants in the upper layers of the soil, creating favorable conditions for the growth and growth of plants for a longer period of time, reducing dependence on short-term droughts, increasing the yield of standard carrot root crops by 20.61% relative to the non-use option polymer gels. On average, in 2017–2019, the yield of standard carrot root crops of the Royal Forto variety in conditions without irrigation with the use of polymer water-retaining gels was 50.9 t/ha, without the use of agrogels – 42.2 t/ha.
