- Abstract
In the technology of winter salads, mineral nutrition, fertilization, genotype and production method are very important for achieving high yield and quality salads. Based on this set a goal to work to determine how the different genotype and production methods affect nitrate accumulation in lettuce. The experiment was conducted in the winter cycle of growing lettuce 2009th and 2010th The varieties using Archimedes RZ, Santoro RZ and Kibou RZ grown on uncovered soil, under black PE foil, under the agrotextile and combination of black PE foil + agrotextile The experiment was conducted by a random bloc system repeating it four times in experimental the field of Faculty of Agriculture East Sarajevo. A two-year study showed a tendency of nitrate increase with various means of production. The minimal level of nitrate was in all three lettuce cultivars on control variante (Archimedes 3020,12 mg/kg; Santoro 2145,75 mg/kg and Kibou 2026,75 mg/kg), however the maximal level of nitrate was in the variant of agrotekstile (Archimedes 3266,10 mg/kg; Santoro 2888,50 mg/kg and Kibou 2423 mg/kg ).
