SUMMARY: Black walnut (Juglans nigraL.) belongs to the genus Juglans, the hickory
family (Juglandaceae A. Rich. EX Kunth 1824), which is a representative of the
Juglandales order. It is a species that is native to eastern North America that was
brought to Europe in 1629. In 1899 the foresters of the great land owner Count Eltz
introduced the seed of black walnut to the area of Eastern Slavonia and Syrmia, because
of the deterioration of pedunculate oak (Quercus roburL.) and because of the
price that the wood of black walnut reaches on the market. Till 1925 the forest management
technique applied was the forest-field technique. Already in 1925 black walnut
cultures covered around 860 ha. The Counts Eltz from Vukovar planted the seed
of black walnut until the Second World War, when they left their land possessions. The
cultivation of black walnut cultures continued after the war and intensified in the seventies,
when the seed was planted in agricultural areas that were gained by reparcelling
and consolidation of holdings. 500 kg of seed per ha is planted in rows with
the spacing of 4 and 6 meters. Between the rows agricultural cultures are sown, and
after three to four years black locust (Robinia pseudoacaciaL.) is planted. At the end
of the twentieth century the growing of black walnut cultures continued and it goes on
today. 500 kg of black walnut seed is planted per ha in the same year after the felling
of the old-growth forest. The spacing between furrows drawn by disc-plough is four
meters, and the seed is planted with a spacing of 25 cm within the row.A kilogram of
seed contains around twenty grains on the average, which makes 10.000 grains per
hectare. In the next year up to 65% of the grains sprout, and in the second year there
are up to 55% or around 5.000 saplings of black walnut on the planted surface. This
can guarantee that in the 80th year by efficient management we shall gain 100 to 120
quality trees of black walnut. Since the planting is done immediately after the felling,
after a year or two between the rows there is a sufficient number of some of the indigenous
or allochthonous tree species, so there is no need for subsequent planting so
as to gain a mixed stand. The forestry office of Vukovar currently manages around

1.300 ha of black walnut cultures and the gross growing stock amounts to ca. 200.000
m3. The cultures of black walnut with a rotation period of 80 years reach an average
breast height diameter of ca. 42 cm and an average height of ca. 33 m.
