The Content Of Chlorophyll And Nutrients In Apple Leaves Depending On Long-Term Fertiliser

An indicator of the condition plants, depending on growing conditions, is state their leaf apparatus, which described by content chlorophyll and nutrients in leaf. The an apple-tree provides synthesis organic substances, productivity fruit trees depends features its vital activity. As a method diagnosing mineral nutrition crops, chemical analysis leaves important, indicators reflect levels plant nutrients. results studies apple Calville Blanc d'hiver seed Idared vegetative M4 rootstocks re-grown plantations nutrition, created long-term (over 86 years) application various systems comfort podzolized soil. Longterm use organo-mineral fertiliser contributed to increase (a+b) clone rootstock at different age periods growth fructification, conditioned further productivity. macronutrients studied cultivar combinations depended options. In most productive period fructification rootstocks, nitrogen areas options was within optimal limits. Among variant without fertilisers, highest rootstock. variety, variants range, among for fertilisers. phosphorus potassium limits
