Institute of Agrobiotechnology in Jelgava, in the heated glasshouse during the period from February 11, 2016 until May 27, 2016. Commercial vermicompost produced by Green-PIK LAT was used with neutralized peat substrates in two different ratios 1 : 4 and 1 : 10. Neutralized peat substrates without vermicompost were used as control samples. Two lily cultivars – Asiatic lily ‘Staburags’ and LA lily (Lilium longiflorum × Asiatic lily) ‘Sonora’ were used for this trial. Three bulbs (5 cm diameter) per cultivar and treatment were planted each in 1.5 L pot. Plant height, leaf length, number and diameter of flowers, as well as flowering time were measured during the experiment. The obtained results showed that vermicompost had a significant positive effect on the plant height and leaf length compared to neutralized peat substrates without vermicompost. The most appropriate ratio of vermicompost and neutralized peat, which had a stimulating effect on the plant height and leaf length was 1 : 4. This study also indicated that vermicompost did not have a significant effect on the number of flowers and diameter, as well as on the time to flowering. Both lily cultivars had flowers in average 70 days after planting.
