Apple tree productivity depending on planting density and rootstock variety combinations

Abstract

In this article has been studied the dependence of tree planting density, variety-rootstock combinations and water- and resource-saving technologies in providing the population of our country with fresh fruits and obtaining a constant plentiful and high-quality harvest. Fruit growing is one of the most important and unique areas of agriculture. The growth, development and productivity of young orchards from seed fruits depend on the planting density of seedlings, the combination of rootstock varieties, the use of water-resource-saving innovative technologies, and agrotechnological factors. In this area, a sharp increase in fruit production, a radical improvement in quality and a reduction in cost are mainly determined by the laying of new intensive orchards and the consistently plentiful and high-quality fruits of existing orchards, including apple tree care and the use of resource-saving technologies. At present, the total area of orchards in the Republic of Uzbekistan is 216,400 ha, of which 89,100 ha or 44.0% of the total area is occupied by seed fruits. On a scientific basis, such activities as the correct formation and pruning of fruit trees, biological characteristics, intensive varieties and planting density of seedlings, modern water-resource-saving agro-care technologies used in the laying of accelerated young fruit orchards in Uzbekistan are studied in detail.
