Abstract
The aim of the experiment was to evaluate the effect of different fertilization levels on growth, flowering and flower quality of Oriental lilies.
Four lily varieties Acapulco, Le Reve, Sorbonne and Siberia were grown in boxes in summer months, from May to August.
Before planting, the peat and sand (9:1) growing medium was amended with the controlled release fertilizer (CRF), Multicote (16:18:21 + 3 MgO), at three levels: 0, control; 2, and 4 g L-1 of soil.
During the vegetation period half of the plants were additionally fed using weekly irrigation with complete fertilizer Peters (15:11:29) at concentration 2 g L-1. Higher levels of Multicote, especially in the treatment without additional fertilization during vegetation, resulted in better quality of all cultivars used in the experiment.
Intensively fertilized plants were taller, had longer flower buds, higher fresh weight and larger, dark green leaves.
The flower buds had better shape and were more upward, compared with non-fertilized control.
For cultivars with long vegetation periods, application of only liquid feeding, without CRF, applied before planting, was insufficient for good plant quality.
