where these varieties are grown.
The first production of fruit varieties studied was recorded in 2003 (table
2). The largest fruit crop has been the variety Golden Reinders - 33.8 t/ha and
lower values for varieties Jonagold - 16.4 t/ha and Ionica - 18.8 t/ha. The
productivity of the other varieties ranged from 20.4 t/ha to 29.0 t/ha.
Higher productivity in 2003 was a negative impact on yield reduction in
2004 accounted for the variety Golden Reinders - 8.4 t/ha, the variety Sir prize -
3.0 t/ha, the variety Idared - 2.0 t/ha and the variety Jonagored - 1.8 t/ha. In other
varieties of fruit production increased by 1.2 to 4.2 t/ha compared with the
previous year.
In the years 2005 - 2006 the varieties with a fruit production in the study
showed an increase from 1.5 to 2.3 times compare with the previous year.
Jonagored varieties, Ionica and Sir Prize were recorded higher values of 50.0
t/ha.

High temperatures during the growing season of 2007 and insufficient
rainfall have a negative impact on production fruit varieties in the study. Crop
varieties in the study decreased by 24.2 to 34.0% compared to the production of
fruit harvested in 2006.
In 2008 fruit production in 2004 was reduced due to the formation of fruit
with floral buds. Since 2009, production of fruit is set, the values obtained are
characteristic super apple plantations, and in 2010 recorded an increase in the
index study.
Productions during the research have been enhanced varieties Ionica -
32.07 t/ha, Gala Must - 32.38 t/ha, Golden Reinders - 32.92 t/ha and Jonagored -
35.06 t/ha. Values bellow 30.0 t/ha of fruit varieties have been Jonagold, Mutsu
and Florida.
The results obtained during eight years of study we demonstrated that the
