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 non-mulched cultivation. Nitrogen nutrition had no univocal influence on morphological traits of bear garlic, while some positive effects of that factor on weight and yield of leaves was recorded. The highest-weight bulbs were achieved in objects that were mulched with pine 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.

Bear garlic (Allium ursinum L.) has been well-known to popular medicine for ages and its pharmacological action is similar to that of common garlic. It is a typical geophyte; occupies wet habitats in ravines and near springs, mainly among beeches and riparian forests. Generative reproduction is the main way for population spreading. The present study aimed at evaluating the influence of mulching using pine bark and varied nitrogen nutrition rates (0; 75 and 150 kg N.ha⁻¹) on flowering traits of bear garlic under conditions of the field cultivation. Mulching using pine bark had positive effects on the length of inflorescence shoot, peduncle, inflorescence diameter, as well as number of flowers in the inflorescence and the plant. During a month, i.e. since April till May, significant increase of inflorescence shoot length at bear garlic has been recorded. In April, they length ranged from 9.0 up to 59.8 mm, while in May from 190.5 to 320.8 mm. Bear garlic inflorescences consisted of 13.4 to 24.0 flowers, with their diameters reaching 19.0 to 53.8 mm. The longest inflorescence shoots and inflorescences with the largest diameter and flower number were produced by bear garlic in the third year of vegetation. No remarkable influence of nitrogen nutrition on inflorescence shoot length and number of flowers per in an inflorescence was recorded.
