THE YIELD OF THE STRAWBERRIES DEPENDING ON THE VARIETAL CHARACTERISTICS

 This article presents the results of studies on 16 varieties of the strawberry on biometric records for varieties of strawberry

first and second year of cultivation in the conditions of North forest-steppe of the Tyumen region. We studied the number of

stems, fruits, the potential productivity and the results obtained the yields of the cultivated plants in extreme weather conditions.

It is revealed that the performance of varieties grown under the same conditions vary in quite large ranges. It has been noted

that potentially fruitful are the varieties in the second year constitute 10 or more stems per bush. It is proved that in the second

year of fruiting varieties of strawberries formed berries 16 % more than in the first year. It is shown that, fruit weight is one of

the main factors determining the yield. According to the modern requirements, it is desirable that the varieties have an average

mass below 10 g. In years of research, all the studied varieties and hybrids meet those needs. It is noted that in the South of the

Tyumen region in the cultivation of varieties of strawberry obtains high yields. Of the studied cultivars the most productive

varieties were varieties of the Regiment and Vima Xima with the yield of 20.2 and 18.4 t/ha, exceeding the control variety by

Festival 9.0 and 7.2 t/ha, respectively. These varieties had the largest average mass of berries of 19.7 and 21.2 g. In 2016 there

was a significant variation in potential productivity from 51.9 to 80 g per bush.


Keywords:

strawberries, variety, flower stalks, fruit, berries weight, the potential productivity, yield, cultivation techniques.
