Apple trees

In 2007 Joint-Stock Company "Agriko AM" tested fertilizer EDAGUM®SМ on apple-trees (breed Pamyat’ Michurina, plantings of 1991) on the basis of Open Company "Medveditsa" of Volgograd area.

Single spraying of trees with fertilizer EDAGUM®SМ (450 ml/hectares) in a period of flower-bud formation was performed

As a result of using EDAGUM®SМ the yield of apples increased by 15 centner/hectare, or on 19% to control; quality of production improved: bigger well colored fruits (40-55 mm against 20-35 mm on control) were obtained; plants were less damaged by diseases (scab, bitter pit spots).

 

In 2008 Research Institute of Gardening n.a. I.V.Michurin studied the efficiency of application of liquid humic fertilizer EDAGUM®SМ in field and small plot trials in apple-trees.

Field trials were carried out in Open Society "Dubovoe" (Tambov area) and Open Society "Agronom" (Lipetsk area). Breed of apple-tree Zhigulevskoe, garden of 1986 year of planting, and planting scheme 8х4 m were used in Open Society "Agronom". Open Society “Dubovoe” used garden of 1991 year of planting, parent stock 54-118, and planting scheme 6х4 m. Rate of working solution for foliar spray was 1000 l/hectare. EDAGUM®SМ was used in mixtures with pesticides (1200 ml/hectare) to improve quality of fruits and increase apple-trees’ resistance to diseases. Trees were treated in phases of a pink bud, 5-7 days after flowering, early fruit drop, in periods of bud set, and intensive growth. Conditions of the vegetative period of 2008 promoted wide development of scab, the main disease of apple-trees.

Results: Spraying of apple-trees (breed Zhigulevskoe) by fertilizer EDAGUM®SМ decreased the development of scab on leaves at an average on 15%, and on fruits on 11% comparably to control treatments (without EDAGUM®SМ). Application of fertilizer EDAGUM®SМ promoted increase of yield on 11% and improvement of fruits quality on 8% to control.

Small plot trial was carried out in work-study unit "Komsomolets" (Tambov area) on apple-trees breeds Venjaminovsky and Stroevsky; garden of 2002 year of planting, parent stock 54-118, planting scheme 6х4 m; plants were sprayed by working solution of EDAGUM®SМ in rates 5 l/tree. Trees were treated in phases of a pink bud, 5-7 days after flowering, early fruit drop, in periods of bud set, and intensive growth. Experimental design:: 1) Control without treatment; 2) N90K90; 3) Treatment with EDAGUM®SМ (12 ml per 10 l of water); 4) N90K90 + EDAGUM®SМ (12 ml per 10 l of water); 5) N90K90 + EDAGUM®SМ (12 ml per 10 l of water) + Aquarin 1%; 6) Double treatment with Aquarin 1%.

Results: application of EDAGUM®SМ on apple-trees of breeds Venjaminovsky and Stroevsky promoted increase of yield on 5.1-7.2 centner/hectare due to lower fruit drop. Joint application of mineral fertilizers and EDAGUM®SМ promoted an increase of yield on 29-30%.
