Abstract:
In the climatic conditions of the Covurlui Plain, it was observed that the
‘Przehyba’ variety starts vegetation the earliest, being followed at an interval of
2-4 days by ‘Laszka’, ‘Sokolica’ and ‘Polka’. ‘Glen Ample’ variety is the latest.
Raspberry fruits ripen usually 30-34 days after the appearance of the first flowers,
‘Przehyba’ being the first variety to start harvesting, followed shortly by ‘Laszka’
and ‘Sokolica’, then by ‘Polka’. ‘Glen Ample’ is the last to be harvested, the
difference between it and the earliest variety existing in the plantation being 15
days. Significant differences between the varieties are observed in terms of the
length of the harvest period, which varies for each one separately. The shortest
harvesting period was recorded for the ‘Laszka’ variety, of only 20-21 days, and
the longest for ‘Glen Ample’, being approximately 28-30 days. In terms of
productivity, the ‘Laszka’ raspberry variety stands out (14.5 t/ha), being followed
by ‘Sokolica’ (12.7 t/h) and ‘Polka’ (11.2 t/ha), and the lowest productions being
recorded at ‘Glen Ample’, with an average of 10.7 t/ha. Among the four variants
of densities taken into account, V4 with 20 suckers shoots per linear meter is the
most productive, registering the highest productions in the case of all varieties.
