To establish the efficiency of using different growth regulators in technological schemes of growing vegetable plants (tomato, sweet pepper, cucumber, large-fruited and nutmeg pumpkin, garlic, onion, carrot, white cabbage). Methods. Field, laboratory, computational and statistical. Results. The results of efficiency of natural and synthetic growth regulators in vegetable growing on their influence on sowing quality of seeds, biometric parameters of plants, productivity and productivity, biochemical composition of production, development of the basic diseases are resulted. Conclusions. When treating seeds with growth regulators, there should be an individual approach for each crop; for each culture should be selected the optimal method of treatment (soaking, pickling) and dosing. To improve the sowing qualities of vegetatively propagated crops (garlic air bulbs) it is more effective to use growth regulators in combination with a complex of microelements (Ikar Bigo Leaves Spring with a rate of 1.0 l/t).The effectiveness and even the direction of action of growth regulators often depends on the species, subspecies and variety of plants. The use of drugs with a complex of phytohormones of cytokinin and auxin nature provides an increase in the yield of large-fruited pumpkin by 2.4–8.2 t/ha, a decrease in the yield of nutmeg - by 2.0–7.7 t/ha. Growth regulators cause a decrease in the content of a number of biochemical components in pumpkin fruits (dry matter, total sugar, ascorbic acid and carotene).The use of growth regulators is more effective in the early stages of plant development. The use of Paslinia for flowering of the fifth and sixth bunches of tomatoes does not provide a significant increase in yield relative to control, while the introduction of the drug with different dosages for flowering of the first and second bunches increases plant productivity by 14.5-16.1%. Growth regulators forplants act as inducers of resistance to major diseases, but with a low level of biological efficiency (42-56% for root rot and 26-38% for false powdery mildew of cucumber). Growth regulators Gibberellin acid (1 mg/l), succinic acid (5 mg/l) and the drug D-2SL (0.5 ml/l) provide an increase in seed productivity of sweet pepper by 1.5-4.1 g/plant or 11.1–30.4%. ER -
