Black locust (Robinia pseudoacacia L.) energy plantations in Hungary

---

Abstract

Establishment  of plantations primarily for fuel production has been of international  interest for    many years. Energy fuel production experiments in Hungary have been  conducted for a longer    time. In the country the black locust (Robinia  pseudoacacia L.) is one of the most  important    stand - forming tree species, covering approximately 20% of the forested  lands and providing    about 18% of the annual timber output of the country. In Helvecia (central  Hungary, sand-soil    region) an energy plantation was established using common black locust and  its cultivars. The    spacing variations of the common black locust were the followings: 1.5x0.3  m, 1.5x0.5 m and    1.5x1.0 m. At the age of 5 the closest spacing (1 .5xO.3 m) produced the  greatest annual increment in oven-dry mass (6.5 t/ha/yr). This exceeds the increments of the two wider spacings    by 33% and 51 %, respectively. Concerning to the results of the yield trial  with black locust cultivars planted in spacing of 1.5x1.0 m, at the age of 5 the highest yield was produced by the    cultivar 'ÜllDi' (8.0 t/ha/yr), followed by 'Jaszkiseri' (7.3 t/ha/yr) and  the common black locust (6.7    t/ha/yr).
