Bear garlic (Allium ursinum L.) has antiseptic, bacteriostatic, and anti-parasitic properties. Besides medicinal features, it is characterized by excellent taste quality. It can be used as a spice and component of numerous dishes. Due to an increase of needs for that material in cuisine, it is necessary to work out nutritional requirements of the species. Therefore, the aim of present study was to evaluate the influence of mulching using pine bark and various nitrogen nutrition rates (0; 75, and 150 kg N.ha-1) on bear garlic growth in the field cultivation. Mulching the soil with a bark had positive effects on bear garlic growth, which was expressed as the length and width of leaf blades, length of petioles, as well as weight of leaves and bulbs. The bear garlic leaves were of 263.1 mm length and 58.6 mm width in bark-mulched objects at the harvest time. The weight of foliage from a single plant ranged from 5.64 to 7.10 g, which was almost twice as high as in nonmulched cultivation. Nitrogen nutrition had no univocal influence on morphological traits of bark and fertilized with 75 kg N.ha-1. It was found that optimum growth and yielding conditions for bear garlic were created by field cultivation using pine bark as a mulching and moderate nitrogen nutrition.
