Abstract
The 1996-2003 field trial on Kwidzyń Lowland heavy alluvial soil (complex of agricultural suitability 8 and class 3b, according to the Polish Soil Sciences Society) aimed at defining the productivity of six willow clones planted from 20,000 to 60,000 plants·ha-1 and harvested in annual cutting cycles. The yield of one-year old stems ranged from 12.51 to 21.52 t of dry matter ·ha-1·year-1. The highest yield of dry matter of wood was recorded for Salix viminalis 082, 19.77 t·ha-1·year-1 on average. Increasing planting density from 20,000 to 40,000 plants·ha-1 resulted in a significant increase in dry matter of wood. A further increase in planting density up to 60,000 plants·ha-1 resulted in a slight yield increase trend only. The water content in one-year willow stems over harvest ranged from 50.4 to 53.1%.
