The aim of the investigations was the assessment of the size of harvest of five energetic basket willow clones at a plantation of the Forest Inspectorate Brodła in the Malopolska voivodeship. The article shows that both in 2003 and in 2006 the highest crops of clone No. 1056 were obtained. However, due to the drought, the harvest in 2003 was lower (27 t/hectare) than that of 2006 (35 t/hectare). The willow Salix viminalis is a plant, which easily adapts to vegetation on any soil. The plant growing does not require any special agrotechnical treatment. The energetic willow cultivation can contribute to economic development of the country and the improvement of the farmer's profits, as well as can help to reduce unemployment. The most important is the fact that the largest demand for manpower in the willow plantation is in winter, i.e. in the time when much less manpower is required in traditional agriculture.
