STUDIES ON THE PHENOPHASES AND PRODUCTIVITY OF SOME VARIETIES OF PLUMS IN POLIMLJE FOR THE PERIOD 1958–1967
Ecological conditions of Polimlje are particularly favourable for the growing of this species of fruit. In view of the very different types of relief in Polimlje with 560–2500 m above sea-level, plum tree grows best on hill slopes facing South, South-East and South-West; especially where the fields are opened to stronger winds with a height of 1,100 m above sea-level.
In the evidence of the communes, plum tree takes part in the income of the agricultural households as follows: 24% in Bijelo Polje, 23% in Ivangrad, etc. With relatively small investments and simple technology of production high yields are obtained.
With this in view that the structure of varieties is unfavourable and that in Polimlje variety Pozegaca accounts for 80% in relation to other varieties (Pozegaca is very susceptible to Prunus virus 7, Marmor cerasi), while 20% are bad for the production of brandy, the aim of this work, hence, is:
- to introduce in the territory of Polimlje varieties of higher quality in order to carry out phenological studies and to choose varieties which prove to be more favourable for the Polimlje district;
- to introduce earlier stable varieties and varieties of plum with bigger fruits, in order to prolong the season of consumption of fresh plums, further to equalize the size of dried plums;
