Karpenko K. Technological and biological peculiarities of tomato’s productivity formation during the organic production in the conditions of the Southern Steppe of Ukraine

The dissertation is devoted to the actual issues of studying the influence and comparison of the action of the anti-stress regulator of AKM and Azotofyte-p and Phytocide-p biopreparations on the biological and morphological features of different tomato genotypes, economic and energy evaluation of organic technology in the conditions of the Southern Steppe of Ukraine. The method of obtaining a better seedlings, enhancing the survivability of seedlings in open soil (Patent declaration for utility model №58258) has been improved. The most effective for soaking the seeds is the concentration of AKM of 3.10-5 g/l, in which the increase of germination energy was marked, similarity and increased the healing of seedlings to 100%. In the dissertation for the first time a scientific substantiation for obtaining ecologically safe tomato products with the use of AKM growth regulator and Azotofyte-p and Phytocide-p biopreparations on dark chestnut weakly soiled soil in the conditions of the Southern Steppe of Ukraine has been applied, which provides yield growth, respectively, at 26, 27 and 10% and the merchandise of the harvest – 5, 10 and 8 %. The most effective from the economic point of view, the variant with the use of preparations AKM and Azotofyte-p, where the level of profitability was 77% (control-43%). The study of bioenergy efficiency of preparations found that the bioenergy factor of tomato cultivation for the effects of AKM and Azotofyte-p rises from 66 to 8,7; Phytocide-p - up to 7,5.
