Opis:
Celem badań własnych było określenie wpływu sposobu i terminu siewu oraz rozstawy rzędów na zdolność i energię kiełkowania nasion życicy trwałej w trzyletnim okresie pełnego użytkowania na nasiona. W badaniach wykazano, że wartość siewna nasion życicy wysiewanej jesienią oraz wiosną jako wsiewka i w siewie czystym była podobna, tylko w drugim roku stwierdzono niewielki korzystny wpływ stosowania rośliny ochronnej na zdolność kiełkowania. Zróżnicowanie rozstawy rzędów w zakresie 12-46 cm nie wpływało na wartość siewną uzyskanych nasion, jedynie w trzecim roku energia kiełkowania była z reguły większa, jeśli życica uprawiana była w rozstawie bardzo szerokiej. Wydłużenie okresu użytkowania życicy trwałej uprawianej na nasiona miało silniejszy negatywny wpływ na energię niż na zdolność kiełkowania.
The aim of the present research was to determine the effect of the sowing method and date as well as row spacing on the germinability and germination energy of seeds over the three-year full use of perennial ryegrass for seed. The research demonstrated that the sowing values of ryegrass seeds sown in autumn and in spring as a companion crop and in pure stand were similar, a slight favorable effect of the cover crop on the germinability was recorded only in the second year. A variation in row spacing from 12 to 46 cm did not affect the sowing value of the seeds obtained, in the third year only the germination energy was, in general, higher if ryegrass was grown with a very wide row spacing applied. A longer use of perennial ryegrass grown for seed showed a more negative effect on the energy than on the germinability.

Opis:
This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters in two – and three-year seedlings of common beech and the occurrence of mites (Acari) in soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. The beech seedlings on the plots where compost had been used as fertiliser were significantly taller than those growing on the plots where mineral fertilisers had been applied. Mulching increased the height of the seedlings significantly only in the last, third year of the study. The tallest three-year-old seedlings were found on the plots in which both of the tested procedures had been carried out. Neither of the factors under study had a significant effect on the diameter of the root neck in the second year of the nursery cultivation, but they increased it significantly in the third year. Fertilisation with compost with an addition of pine-tree bark increased the number of leaves per plant and the leaf area in two – and three-year-old seedlings. A beneficial and significant effect of mulching on these parameters was found in the third year of cultivation. A significantly positive effect of mulching on the mite gathering density was recorded in the second year of the nursery cultivation. However, both of the experimental factors had a positive effect on the occurrence of those arthropods in the third year of the study. Oribatid mites were the most numerous mite order and they were found in the greatest density on plots where mulching had been applied. Fertilisation and mulching increased the Oribatida/Actinedida ratio, which may indicate an improvement of the biological balance in the soil environment.

Opis:
This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters for two - and three-year-old Scots pine trees and on the incidence of mites (Acari) in the soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. Organic fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark resulted in a significant increase in the plant height and the diameter of the root neck in two-year-old pine trees. The effect of mulching on these parameters was not significant. The synergistic effect of the factors on the plant height and the diameter of the root neck was not significant. Organic fertilisation significantly increased the height of 3-year-old pine trees, whereas it did not have a significant effect on the root neck diameter. Mulching increased the plant height significantly, but no statistical effect on the diameter of the root neck was demonstrated. Although no significant interaction of either experimental factors in their effect on the plant height and the diameter in the root neck was observed, the parameters tended to increase in the experimental option, which included organic fertilisation and mulching. Mulching had a significant effect on the presence of soil mites, especially oribatid mites (Oribatida). Their density increased greatly after the procedure. This growth, as well as an increase in the ratio of Oribatida to Actinedida could be a sign of improvement of the biological balance of the soils under study and their biological activity.
