In this article, the influence of foliar treatments with complex fertilizers (Polimiks-agro, Sprühdünger 2) and a growth regulator (SeaweedMix) in the cultivation of rootstocks and seedlings given the concentration of drugs and phase of plant development. The positive effect of fertilizer "Polimix-agro" on physiological processes in plants of SC2U apple rootstock in the formation of adaptive resistance to abiotic stresses of the summer period, where the best water-holding capacity of the leaves than in the control. It was found that a single non-root feeding in the uterine growth regulator called SeaweedMix when reaching rootstocks height of 10-15 cm, allows to increase the yield by increasing the growth activity, increase the standard of layering with a decrease in the number of lateral branches, as well as 3-fold non-root fertilizing fertilizer Sprühdunger 2 provided an increase in the quality of rootstocks on the diameter of the trunk and height

In FSBRI «North-Caucasus zonal scientific-research institute of horticulture and viticulture» (Krasnodar) there was carried out the comparative economicbiological study of the average-height apple-tree stock М9ЕМLA in comparison with initial weakgrowing stock М9 in manifold, nursery and garden. Manifold bushes of the clone M9ЕMLA is quite worse in force than the stock М9 and were less branchy. Output of standard per hectare of manifold at the clone M9ЕMLA was on 35,5 thousand units more, and а standard condition of cuttings - on 13,2 % higher, than at the stock М9. Cuttings of the clone were less spiked and better rooted. In the first field of nursery, the plants of the clone had a vertical growth of the central conductor, slightly weaved and were more suitable to inoculation. The output of standard plants, in the variant with the use of clone M9ЕMLA by the variety Champion, in average for 2006-2010 was on 3112 units/hа, and on the variety Prikubanskoye – correspondently on 2470 units/hа higher than grafted on the stock М9. The cost price of 1000 seedlings on the clone M9ЕMLA was on 1962 rubles less than on the stock М9, and the standard of profitability of seedling growing, on the contrary was on 14-19 % higher. In the garden the trees on the clone M9ЕMLA were worse in growth of trees grafted on М9: on volume of the crone on 0,4-0,6 m3 , in diameter of the stem on 9-12 mm, in dependence on the variety, independently on the fact that some trees on clone were more weaker than grafted on the stock М9, their productivity for 2011-2015 was higher as from one tree as from the unit of area. The intensity of fruiting expressed in yield in kilos from a tree on the unit of volume of the top of a tree on the clone M9ЕMLA was on 33-39% higher than at the trees on the stock М9
