Influence of fertilizers with growth-stimulating preparations and mineral fertilizer on the efficiency of table beet in the conditions of irrigation

Abstract

The use of plant growth stimulants and biological preparations is the most promising direction of the modern development of crop production. Currently, the assortment of substances that have a regulatory effect on plant growth and development is widely known. Favorable climatic conditions in the south of Russia make it possible to obtain high and stable crops of vegetables, including table beets, on irrigated soils.
 For the first time in the light chestnut soil of the Astrakhan region, a study was conducted of the influence of foliar treatments with modern growth-promoting preparations and mineral fertilizers aimed at increasing the yield and quality of fruits of vegetable crops under drip irrigation
 Studies on the cultivation of varieties and hybrids of beetroot were conducted during 2018-2019. on the lands of the FGBNU "PAFSC RAS". Based on the results of the field experiment, high biological yield indicators of 88.8 t / ha in the study were obtained from the Ethiopka cultivar using the variant using sheet treatment with Aminovit liquid complex fertilizer. The water consumption coefficient was 64.2 m³ / t. Moreover, the increase to the control option was +6.8 t / ha, marketable yield was 65.6 t / ha. According to the results of biochemical analysis, a low nitrate content was observed in the Ethiopka variety 1034.0 mg / kg in the variant using the Aminovit fertilizer. According to the sum of sugars of 8.5%, two varieties of Mulatka and Khutororyanka were distinguished using the variant with the use of the drug Aminofol Plus. It is necessary to highlight the following, that the use of growth-promoting drugs led to a significant reduction in nitrates relative to the control in the root crops of cultivars and hybrids of table beet being studied.
