Influence of various factors on commercial quality and preservation of apple fruit of cv. ‘Nadzeyny’
Abstract
The studies to assess the influence of various factors (rootstock, non-root application of complex fertilizer Komple-Met-Ca, weather conditions of the growth season) on the quality and preservation of apple fruits of the Nadzeyny variety (late maturation period), were conducted in 2017–2018 in experimental garden of Department of Fruit Growing Technology in the RUE ‘Institute for Fruit Growing’ (Belarus) in the soil-climatic conditions of the western sub-zone of the central fruit zone. The garden was made in 2010, on clonal dwarf rootstocks – PB-4, 62-396 and M-9 with a planting scheme – 3.5 × 1.0 m.
The commercial quality of fruits during the harvest (the average weight and yield of fruits according to commercial classes) depended on the conditions of growing periods in the years of research. With higher average fruit weight, higher yield of fruits of the highest and first commercial classes was also observed, but the safety of such fruits after long storage was worse.
The use of complex fertiliser KompleMet-Ca provide better preservation of fruits during long-term storage: on average, over two years, the yield of healthy fruits on the PB-4 rootstock was 85.8 % (against 82.9 % in the control), on the 62-396 rootstock – 88.6 % (against 88. 0 % in the control), on the M-9 rootstock – 92.1 % (against 89.8 % in the control).
The yield of healthy fruits after storage was the highest for trees on rootstock M-9. The worst stored fruit was taken from trees on PB-4 rootstock.
