The purpose of the work is to determine the effectiveness and impact of the combined use of fertilizers and growth regulators on the yield, quality and environmental safety of vegetable products. Field experiments on the research topic were conducted in 2004–2005 and 2012–2017 on the alluvial meadow soils of the Moskva River (Ramensky district, experimental production facilities «Bykovo») and the floodplain of the Oka River (Lukhovitsky district, state farm «Krasnaya poima»). The experimental plots were located in the central part of the floodplain, in vegetable irrigated crop rotations. Vegetable crops were cultivated in accordance with the recommendations of the ARRIVG – branch of FSBSI FSCVG. The highest yield of white cabbage (97.6–115.1 t/ha) is provided by the combined use of the calculated dose of mineral fertilizers (N160P100K180) with potassium humate and Circon. The use of the F1 Goodman hybrid of mineral fertilizers in a dose of N120P60K150 for cauliflower increases the yield of heads by 44%. In turn, the use of growth regulators Gumistar and Circon increases the productivity of this crop by 15 and 29%, respectively, while maintaining good quality cabbage. On the broccoli culture of the F1 Marathon hybrid, mineral fertilizers increase yields by 56% (up to 13.4 t/ha), and growth regulators Humistar and Cyrcon – by another 38 and 45%, respectively, with an increase in the content of ascorbic acid in the heads. When cultivating onions of the F1 Bennito hybrid, the use of the Circon growth regulator provided an increase in yield by 14% (up to 46.6 t/ha) with a significant increase in sugars in products and a decrease in nitrates in it. When growing dietary vegetables, in particular the F1 Belogor squash and the Cheburashka squash variety, the use of the Circon growth regulator allowed to increase the yield of squash fruits by 8% with a decrease in nitrates in products from 440 to 365 mg/kg, and the yield of squash fruits by 13% with a decrease in NO3 in products from 468 to 358 mg/kg.
