Description
The article presents the results of studies on the influence of the conditions of the Piedmont horticulture zone of the Krasnodar region and the shape of the crown on the productivity of apple trees. Objects of study were trees of winter apple varieties Idared and Renet Simirenko grafted on MM 106 rootstock. The trees were planted according to the 5 × 3 m pattern. In the eighth year, the rounded crowns were transformed into flattened across the row (from the eastern and western sides of the tree) to crown width 2.0 ... 2.5 m. Orientation of rows was from east to west. The garden is located on the northern slope with a slope of 3 degrees. Scheme of experiment: option 1 - sparse-tier crown (control); option 2 - flattened crown. In the experiment, 2 variants; in each variant, 10 typical trees were taken. Repetition tree plot. The place of the experiment is Abinsky district of the Krasnodar region. Agrocounts of indicators of fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was carried out by the method of analysis of variance described by B.A. Dospekhov. The results of our studies showed that flattening the crown of apple trees contributes to an increase in the number of fruits formed on them per unit volume of the crown in the variety Idared to 10.1 kg or 1.87 times, and per m2 of the projection of the crown to 15.5 kg or 1.72 times more than crowns without flattening. In the variety Renet Simirenko, the number of fruits according to the same indicators increases by 1.86 and 1.74 times. Also, when flattening crowns, the yield of apples from one tree in the Idared variety increases by 9.6%, and in the Renet Simirenko variety decreases by 7.7% compared with the control

Description
The article presents the results of studies on the influence of the conditions of the foothill horticultural zone of the Krasnodar region and the crown shape on the agrobiological characteristics of the growth and fruiting of apple trees of the Idared and Renet Simirenko varieties. The objects of the study are Idared and Rennet Simirenko, trees of winter apple varieties, grafted on MM 106 rootstock. Trees were planted according to the 5 × 3 m scheme; crown width 2.0 ... 2.5 m. Orientation of rows from east to west. The garden is located on the northern slope with a slope of 3 degrees. The scheme of experience: option 1 - sparse-tiered crown (control); option 2 - flattened crown. In the experiment there were 2 options, in each option 10 typical trees were taken. Repetition: tree - plot. The location of the experiment is the Abinsky district of the Krasnodar region. Agricultural records of growth and fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was performed by the method of variance analysis described by B. Dospekhov. The results of our studies showed that when flattening crowns, the variety Idared increases the average weight of apples by 22.9%, the yield of fruits of the highest and first grade by 43.6%, the intensity of integumentary coloring of fruits in the peripheral zones increases by 1.44, and in the center crowns 2.7 times, compared with sparse-tier crowns. In the variety Renet Simirenko, the fruit weight increases by 8.9%, the yield of the highest and first grade fruits by 14.6%, the number of fruits with color by 18.7%. Thus, in apple orchards with a 7 x 4 m planting pattern (on MM106 stock) under the conditions of the foothill horticultural zone of the Krasnodar region, flattened tree crowns should be formed for the Aydared variety (aged 14-15 years), which significantly improves the quality of the products

Description
The article presents the results of studies on the biological characteristics of growth and fruiting, as well as the yield of adaptive varieties of strawberries in the conditions of the Prikubanskaya horticulture zone of the Krasnodar region. The objects of study are new and promising varieties of strawberries: Zenga-zengana (k), Onda, San-Diaz. The experiments were performed using the method of randomized reps. In the experiment there are 3 options, in each there are three replications of 20 plants. Variants and repetitions are placed sequentially. Agricultural records of the growth and fruiting of strawberry plants were carried out according to generally accepted methods; statistical processing of research results was carried out using the analysis of a variance method described by B.A.Dospehov. The results of our research showed that Zenga-zengana bushes (control) turned out to be the tallest. In the Onda variety, the height of the bush is 2 cm less than in the control variety; and San Diez varieties are 4 cm, respectively. It should be noted that the most undersized plants require a smaller area of nutrition. It has been established that flowers pollinated a few days after their disclosure develop more rapidly into berries than those that were pollinated immediately after opening. Pollen in flowers of the first order is less than in flowers of the third or fourth order. The stamens of the first flowers are often underdeveloped, their pollen is released and germinates worse. In our experience, the average weight of fruits and the yield as a whole depends on the biological productivity of the varieties. Onda was the most fruitful variety, and the rest varieties were at the control level
