The area of study: agriculture, fruit growîng.
The aim of research: Is to increase the quantity and quality of apples by applying foliar fertilization and norming the fruit load to the Golden Delicious, Idared and Florina varieties grafted on the M26 rootstock.
The objectives: identify basic indices of growth, photosynthetic productivity and fructification; determining the concentration and optimal timing for applying foliar fertilizers; setting load of fruit by fruit thinning method and time limits for such treatments; Determine the effect of foliar fertilization and fruit thinning on the productivity and fruit quality; economic estimation of apple production by variety, foliar fertilization system and fruit thinning.
Novelty and scientific originality: It is the dynamic analysis of the growth and fruiting apple varieties Golden Delicious, Idared and Florina grafted on rootstock M26 depending to the application of foliar fertilization and fruit thinning; The rationale of integrated use of mineral fertilizers and fruit thinning on the phenological phenophases, in order to increase the fruit production and improve the quality of apples; application of foliar fertilization [Urea 46% N, (NH2) 2CO; Poly- Feed (NPK 19:19:19 + Mn, Cu, Zn, Fe, Mo, Mg); Calcium chloride (CaCl2)] integrated fruit thinning [Bioprzerzedzacz 060 SL (ANA 10g / l BA + 50 g / l)] through scientific argumentation to increase the economic efficiency of apple production.
The solved scientific problem:resolved is, establishing the application mechanism integrated with the foliar fertilization and fruit thinning in intensive apple orchard in order to obtain competitive fruit production.
The theoretical value of the study:of the paper is in the process based on scientific methodology of analysis, assessment of the growth and fruiting apple tree in the context of finding the most effective methods of standardization and application of fruit thinning and administered the foliar fertilizers.
The practical value: The innovative scientific contribution helps to identify the dose administered of foliar fertilizers, fruit thinning method during of the application with fruit and chemicals în order to obtain consistent and quality apple yield.
The implementation of scientific results:The results of scientific research have been used for preparation Technology book "Producing apples", Chişinău 2013 implement in farms, S.A. "Zubreşti" LLC "Prodcar", "Vindex Agro", "Balcom Agro Group", "Biovit confirmed by implementings act
