Opis:: This experiment was conducted to assess regrowth of shoots of willow in the four-year cultivation cycle. Length, thickness and number of shoots in the carp were affected in the most by years of willow shoots regrowth, less by variety and time of measurement, and the least by density of cuttings planting. Among the interactions of these characteristics big importance has interaction between varieties and years of regrowth of shoots and between varieties and the density of cuttings planting. The average of the ten varieties of willow the longest and the thickest stems were obtained by planting 22,134 cuttings per hectare. Tested varieties of willow, were characterized by different reactions to the density of cuttings planting in the analyzed features. The varieties 1047D, Start and Ekotur had the longest and thickest shoots at the density of 15,020 units.ha -1, varieties Turbo, Oloff and Tordis - at the density of 22,134 pieces.ha-1, and varieties 1054 and Sprint - at the density 35,200 units.ha -1. For variety 1047 the longest shoots were at density of planting of 22,134 pieces.ha-1, but the thickest stems - at density of 35,200 units.ha-1. The biggest number of shoots in carp was at the density of 15,020 pieces.ha-1, except for varieties Ekotur, Oloff and Jorr.

Opis:: The aim of this study was to evaluate the reaction of 10 willow varieties to damage inflicted by hunting deer (Cervus elaphus L.) and European roe deer (Capreolus capreolus L.) at different fertilization with nitrogen (0, 60, 120 and 180 kg ha-1 N) in the years 2008-2011 in the vicinity of Koszalin. Such damages as grazing of tops of shoots, debarking and fracture of shoots and total damage were evaluated at the end of the willow vegetation period. Yield of fresh mass of shoots was determined in November 2010 (third year of cultivation) and 2011 (fourth year of cultivation). Regression equations for the yield of shoots at different damage hunting were created. Level of hunting damage was most strongly influenced by age of cultivation (21.7%), variety of willow (21.3%) and the interaction between of those factors (16.9%) and less – nitrogen (1.7%) and interaction between varieties and doses of nitrogen (1.1%). In the first and second year of regrowth of willow, in case of thin stems, grazing their tops dominated, and in the third and fourth year of cultivation, in case of thicker stems, their debarking and breaking of their shoots intensified. It was shown that for 1% of total loss, yield of fresh weight decreased from 0.251 t ha-1 for 1054 variety to 0.973 t / ha t ha-1 for Ekotur variety, and in average of 10 varieties – decreased by 0.416 t ha-1 . The authors would like to thank Lillohus AB company, 291 61 Kristianstad, Sweden for donation of Oloff, Jorr and Tordis varieties for test and to Mr. Przemysław Dobrzaniecki from Agrobränsle AB in Poznań for participation in this donation.

Opis:: Najważniejszym źródłem energii odnawialnej w Polce jest biomasa, a jej udział w bilansie paliwowym wynosi około 90% [4]. W ostatnich latach znaczenia nabiera biomasa rolnicza, szczególnie z drzew szybko rosnących. Zapotrzebowanie energetyki na biomasę jest bardzo duże - ok. 17,5 mln ton [3]. Wyprodukowanie takiej ilości biomasy każdego roku wymaga opracowania efektywnej technologii jej pozyskiwania, z uwzględnieniem gatunków roślin i odmian, oraz warunków uprawy i zbioru. W Polsce duże nadzieje pokłada się z uprawą wierzby krzewiastej. Ograniczenie nakładów finansowych na jej uprawę, może zachęcić do rozwijania produkcji biomasy stałej z wierzby. Celem pracy była ocena dynamiki odrastania pędów dziesięciu odmian wierzby krzewiastej (Salix viminalis) w trzyletnim cyklu, uprawianych w rejonie Koszalina, na glebie lekkiej, o głębokim poziomie wody gruntowej, zróżnicowanym zagęszczeniu krzaków na hektarze.
This experiment was conducted to assess regrowth of shoots of Salix viminalis in the three-years-cycle of cultivation, of ten varieties of willow, on the light soil, at different density of planting bushes per hectare (15 020, 22 134 and 35 200 pieces). The importance of studied factors on the variability of height, thickness and number of live shoots in bush in order of decreasing main effects was as follows: years of shoots regrowth, time of measurement, varieties and density of planting of willow. Following interactions: years of willow shoots regrowth with varieties and varieties of willow with planting density were important for all features. Increase shoots length were arranged according to the rainfall during the growing season of willows and were highest in 2009, lower in 2010, and the lowest in 2008. The longest shoots were in the objects with density of planting 22 thousand of bushes and the shortest at planting of 15.0 thousand of bushes per hectare. Number of living shoots in the bush decreased with increasing density. On average, the longest and thickest shoots had Ekotur variety, shortest - Start variety, and thinnest - 1054 variety The least living shoots in the bush was found in Oloff variety the most Sprint variety. The longest shoots in all planting densities had Ekotur variety, and the shortest varieties: 1047 at planting 15 020 bushes per hectare, 1054 at planting 22 134 bushes per hectare, and 1047D at planting 35 200 bushes per hectare. The biggest differences of shoot length between the planting densities were observed for Oloff variety, and the smallest - for Start variety. The dynamics of decreasing of number of living shoots between planting densities was different for varieties of willow. The biggest differences in the number of living shoots between the planting densities was observed for 1047D variety, and the lowest - for 1047 variety.
