    INFLUENCE OF FERTILIZATION ON GROWTH AND QUALITY OF LETTUCE
    (Biotechnical Faculty of the University of Montenegro, 2020) GOVEDARICA-LUČIĆ, Aleksandra; PERKOVIĆ, Goran; RAHIMIĆ, Alma; BOŠKOVIĆ, Ivana; PAŠIĆ, Sanid
    The biological characteristics of lettuce and its specific growth and development are the basis for establishing the optimal method of cultivation. In order to achieve appropriate high yields, producers various organic, mineral and microbial fertilizers. The aim of the study was to determine the effect of fertilization on the growth and quality of different varieties of lettuce. A two-factor experiment (fertilization and variety) was set up on a random block system in a greenhouse without heating, on the territory of East Sarajevo. A non-fertilized control variant was included in the trial. During the research, the effect of fertilizers (Slavol and Fitofert humisuper) on two varieties of lettuce (Santoro RZ and Kiribati RZ) was examined. The highest mass of lettuce was recorded on the variant with application of Slavol (309,19 g).The highest percentage of dry matter was achieved by fertilization with Slavol in the Kiribati RZ variety – 6,46%, while the lowest percentage was achieved on the control variant in the Santoro RZ variety - 5.10%.

    MINERAL CONTENT IN A SALAD LEAF (Lactuca sativa l.) DEPENDING OF THE GENOTYPE AND APPLIED AGRICULTURAL MEASURES
    (2015) GOVEDARICA-LUČIĆ, Aleksandra; PERKOVIĆ, Goran
    Four different production methods applied on three genotype of lettuce (Archimedes RZ, Santoro RZ, Kibou RZ) – have been estimated in a two-year experiment carried out at the Agricultural University of East Sarajevo. The experiment has been conducted during two-year period; lettuce was cultivated by using four different mulch materials: black PE foil, agro textile, a combination of PE foil and agro textile; control variant (bare soil). After harvesting lettuce, evaluated the content of the following minerals (N, P, K). The values of nitrogen content tend to increase from bare ground (7.47%) to a covered soil (7.98%). The reaction genotype on variants coverage shows an interaction effect. Type of material for covering soil also has an influence on the content of potassium. The highest potassium content of 4.87% was recorded at the variant of covering with agro textile, or by 18% more in comparison to the control variant.
