Effect of Osmocote fertilizers on the viability of winter apple grafts in the Krasnoyarsk forest-steppe

Abstract

Apple tree is a common fruit crop in Siberia. It is possible to grow annual standard seedlings using elements of intensification: irrigation, mechanization of all labor-intensive work, protection from diseases and pests, and the use of fertilizers. The percentage of graft survivals depends on the yield of seedlings for sale. Application of Osmocote Pro fertilizers when planting winter grafts of an apple-semi-crop variety Vospitannitca contributes to better grafting survival rate (77.5%) compared to the option without fertilization (38.0%) and relative to the option using Osmocote Exact Standard fertilizer (68.0%).
