THE STUDY OF SOME HYBRIDS OF TOMATOES IN SUN GREENHOUSES IN KOSOVO

Tomato is one of the most important and most spread vegetable plants in Kosovo, which has been planted in about 2000 hectares, annually.
There have been eight hybrids of tomatoes studied (Jaguar, Arleta, Gardel, Big Beef, Amati, Marfa, Red Chief, Optima) in sun greenhouses conditions all around the region of Anadrini, Kosovo.
During the vegetation period in the periodical way, the following have been measured: biometrical indicators of vegetative masses, biometric indicators of the fruit, dynamic and a total production according to the hybrids.
The scheme during the process of the experiment was “randomized block” with four replications.
The following parameters have been studied: the height of the first floor from the ground, the number of the leaves till the first floor, the length and the wideness of the leaf, the thickness of the stem measured in centimeters.
The number of leaves until the first blooming gives a result in the limits of 6.4 till 7.5 leaves; these are some of the values manifested to the hybrids Marfa and Amati.
The third period of blooming until the fourth blooming gives the result in the limits of 18.1 until 24.8 cm, these are some of the values appeared and manifested according to the Optima and Red Chief, and the other hybrids are located inside of this interval.
The size of the leaves moves toward the limits of 38.8 till 43.2 cm and all these appear to the hybrids of Arleta, except Gardel hybrid, other hybrids are inside of this interval.
The wideness of leaves gives the result in Amati and Gardel hybrids in the limits of 35.56 till 41.2 cm, whereas other hybrids are inside of this interval.
