The influence of length of cuttings on establishment of a short rotation plantation was investigated over a period of two years using direct field planting of unrooted Populus "Rasumowskiana" cuttings. Teh longer the cuttings, the higher were the survival and dry mass production. Survival at the end of the second growing season varied from 75% to 97%. In two years, the two longest cutting lengths (40cm and 50cm) produced about 100g dry mass per living cutting; but owing to the higher survival rate of the longest cuttings, there was a difference per area unit: 360g/Quadratmeter for 50cm long cuttings. The shortest (10cm) cuttings produced only 115g/Quadratmeter.
