Biometric indicators of varieties in a young apple orchard to provide the population with environmentally friendly products

The main purpose of our research is to study the biometric and productivity indicators of trees in the apple orchard in Sheki region, depending on the technology of care. Apple is the most widespread fruit plant in Azerbaijan. According to the area under cultivation and production, apples are the first fruit crops. Apple is the most valuable fruit plant due to its valuable biological properties and economic indicators. Golden Deliches, Granny Smith and Starkrimson varieties of apples and M9 rootstock were taken as the material of the research. The research was fulfiled in Sheki region. The apple orchard was planted in 2017 in the Incha village territory of Sheki region. The issues covered in the research program were studied on the basis of generally accepted methods of horticulture. The number of shoots in the tree of Golden Deliches is 8.8 in 2020 and 14.9 in 2021, with an average of 11.85 per year. The average length of a shoots is 0.40 m in 2020 and 0.35 m in 2021, with an average of 0.38 m per year. The annual height increase per tree was 3.52 m in 2020 and 5.22 m in 2021, with an average of 4.37 m over the years. The number of shoots in the tree of Granny Smith variety was 9.0 in 2020 and 17.9 in 2021, with an average of 13.45 per year. The average length of a shoots is 0.45 m in 2020 and 0.32 m in 2021, with an average of 0.39 m. Thus, the annual height increase per tree of this variety is 4.05 m in 2020 and 5.72 m in 2021, with an average of 4.89 m per year. In Starkrimson variety, the number of shoots in the tree was 8.6 in 2020 and 16.7 in 2021, with an average of 12.65 per year. The average length of a shoots is 0.38 m in 2020 and 0.30 m in 2021, with an average of 0.34 m. Thus, the annual height increase per tree of this variety was 3.27 m in 2020 and 5.01 m in 2021, with an average of 4.14 m per year.
