Objective: the process and patterns of the cauliflower`s quality formation and preservation.Purpose: the experimental substantiation of adaptive elements of the production technology of cauliflower, which provides the selection of the different ripening terms hybrids, the usage of the plant growth regulators and the choice of methods of packaging products that would provide high economic and bioenergy indicators.Methods: general scientific, field, laboratory, statistical. Novelty: the best cauliflower hybrids have been identified by multi-criteria optimization in terms of yield and quality; the models of forecasting yield of cauliflower have been developed; the effects of the plant growth regulators such as Humisol-Super, Vympel, and Megafol on the growth, development, yield and product quality of cauliflower hybrids have been studied; the physical and thermal properties of the heads of various cauliflower hybrids have been established; the comparative evaluation of the cauliflower products safety was carried out depending on the type of packaging, the hybrid characteristics and the conditions of the growing season. Results: it was determined the potential of cauliflower hybrids and the parameters of their adaptability to the conditions of the Left-Bank Forest-Steppe of Ukraine. It has been established that the yield and mass of the hybrids' heads have a strong direct dependence on the HTC, the amount of precipitation during the growing season and the average daily air temperature (r = 0,93 ± 0,01 ... 0,99 ± 0,01). The best hybrids of early-ripe cauliflower (Livingstone F1, Kul F1) and late-ripe hybrids (Skywalker F1) for cultivation in the conditions of the Left-Bank Forest-Steppe of Ukraine were identified. The effectiveness of the growth regulators usage on cauliflower plants was evaluated according to Harrington`s desirability function method. It has been established that the duration of the growing season of cauliflower hybrids by 44,0 % depends on the hybrids` characteristics; the effect of growth regulators is 19,0 %. It was determined that a greater yield of hybrids' marketable products provides their packaging in the perforated stretch tape – 83,9–84,0 % for 60–70 days of storage; late-ripe hybrids – in the stretch tape – 83,0–83,7 % for 100–130 days, depending on the hybrid type.The level of implementation: the 1 collective monograph, the 1 patent for a utility model. The effectiveness of the developed elements of the cauliflower production technology is confirmed by the results of implementation in the two farms of the Kharkiv region.
