Tomato is one of the most important and most distributed vegetable crops in Kosovo that is being cultivated each year in an area over 2000ha, with little oscillation throughout years. The tomato cultivar Jaguar was used in our study while the investigation was performed in tomatoes cultivated in four variants (six, eight, ten and twelve levels of plant growth-floors). During our investigation there were monitored and analyzed phonological data, biometric indicators of plant and fruits, bloomed (opened) flowers and fruits formed, earliness indicators of the variants, yield according to the harvesting period, dynamic of the production and economic evaluation in conditions of sun greenhouses in Anadrini region, Kosovo. The experiment has been set up according to randomized block design in four replication. The investigated parameters were: plant height in cm, the height of the first level (first floor) from soil surface, stem width in cm, average fruit weight, the number of bloomed flowers and fruits formed, early maturity, indicators of the variants in production. The plant height in cm of the variants was from 155cm at first growth level (first floor) to 253 cm at fourth growth level. The number of bloomed flowers at first floor was 94.44%, to the forth variant (floor) was 92.84%, while as for other variants it was between these two values. The height of the first floor was in range from 25.50 to 27.50cm for first and fourth floor respectively, whereas for other floors it was between these values. The average weight of fruits resulted to be within ranges from 187.54 to 169.58gr for first respectively fourth floor, whereas for other floors it was between these values. Stem width resulted to be within ranges 1.53-1.35cm, values shown at first and fourth floor while other floors were within these values.
