Purpose of the research - scientific substantiation and development of measures of quality improvement and maturation capability of onion and beetroot. Phrase objects of study - the process and regularities of formation of quality and keeping quality of onion and spicy varieties Tkachevsky Peninsula varieties rainbow, beet varieties of Bordeaux Kharkiv and Vital. It was researched and substantiateed on the processes of accumulation of nutrients and their under an hour of storage and the change in bulb onion beet. Using statistical analysis of the results of the study revealed the factors influencing the storability of the products. In particular the preservation of onions has a direct correlation close correlation with dry matter content (R=0,80 - 0,94) and Mizuki/ monosaccharides (R=0,72-0,98) and feedback content Monochoria (g= - 0,77 - - 0,95). The higher the value of the ratio of Mizuki/monosaccharides is, the better the keeping quality is characterized by the production of onion. Based on data we developed technological methods that enhance the keeping quality of production of the studied crops. Foliar onion fertilizer "Nutrivant plus" at the rate of 2 kg/he contributed to the increase of commercial products 6 months after storage at 2.2-3.5% in comparison with the standard (82,2-75,4% respectively of grade). Pre-harvest treatment with growth regulator phazor in a concentration of 0,25, 0,5, 0,75 and 1,0 % during storage to reduce sprouting by 48,7 90,7 per cent in the variety Tkachevsky and by 46,4 - 64,2% of the variety rainbow, which enhances the safety of products to 86.5 - 91,6% and 72,5 - 80,0%, respectively. Integrated application of biological products Planes, Trichoderma, Field and Gaupsin onion bulb during storage and cultivation before putting it in reduced product losses 19,3-42,0 % compared with the control (without treatment) where the losses amounted to 15,0 per cent and 31,9 per cent depending on the variety. Before - and after-harvesting processing of beet the biologics Baikal EM-1U, Gaupsin and Field-R contributed to increasing the safety of the roots (180 days storage) varieties of Bordo Kharkiv 13,0 - 15,8 %, the varieties are Vital 16,6 - 19,5 %; control - by 63,8% and 71,0 %, respectively. The application of organic fertilizers Aravt-KOR in a dose of 2 t/he and Agrovit-KOR 1 t/ha + N30P30K60. enhances the safety of the crops and to 77,5 per cent and 95,4 per cent depending on the variety. Scientific and technical level of studies corresponds to the current requirements for research.
