When forming the quality of strawberry berries one of important elements is the use of the fertilizers capable to protect the plants from external influences and to purposefully regulate their growth and development. In this work it is presented the results of use not root feeding by liquid complex fertilizer with micro elements of "Alga Mix B Mg" for different phases of development of strawberry plants of Onda for control of harvest formation and a chemical composition of berries. As a result of the carried out research the positive influence of the complex fertilizer on strawberry productivity is established: the number of flowers exceeded control for 2,3%, the number of developed berries - for 23% with increase in average mass of berries by 15%. It allow you to receive a harvest on 5,8 t/hectare higher. The use of not root feeding of strawberry by complex fertilizer of "Alga Mix B Mg" has allowed to improve the quality of berries: the content of soluble solids and sugars increased on 2,3%, vitamin C - on 41,1%. It is shown the improvement of tastes of strawberry berries under the influence of non root feeding due increasing in content of sugars and decrease in acidity. The strengthening of intensity of berries color connected with increase in quantity of anthocyan pigments for 13,8% favorably affects the commodity and consumer qualities of strawberry, and also the acceleration of berries maturing (for 3-4 days) demonstrates. The results of the carried out research show that by means of not root top dressing by complex fertilizer of "Alga Mix B Mg" possibly to increase in productivity, commodity qualities, nutrition and biological value of strawberry berries.
The widespread and high harmfulness of mycoses of strawberry roots are established in the conditions of Krasnodar region. The tolerant varieties to complex of root pathogens are allocated. The effective ways of plants treating before planting are given for control of pathogens of strawberry root rot. The imbalance of ratio of nutrient elements in the leaves is established, that indicates about need of correction of fertilizer system of strawberry plantings, cultivated according to intensive technologies
The results of research of 8 modern remontant raspberry varieties adapted to technologies for crop of berries in autumn period at the annual shoots are presented. The complex biochemical and technological evaluation of raspberries on commodity quality, content of soluble solids, sugars, organic and amino acids, vitamins and polyphenols is given. Varieties for targeted use in the manufacture of jam and frozen products are allocated
