INDIGOBUSH BIOMASS PRODUCTION IN MANAGEMENT UNIT „SLAVIR“     pdf     HR     EN 419
Summary
Research was conducted in the area of UŠP Vinkovci, Forest office Otok, management unit „Slavir“, on five sample plots (figure 3-6).
In winter, felling of all indigobush plants on selected plots was done and their mass was determined. Samples for gravimetric moisture content determination and stereometric volume determination were taken. Density of fresh samples was calculated. Same method was applied for oak and ash young plants on extra sample plot.
On the same plots samples for vegetation period moisture content determination were taken in summer.
Average moisture content (figure 9) of 30.25% in wintertime (W) and 48.38% in sumertime (S) was determined. Based on the mass of all plants, average moisture content and size of each sample plot production of dry matter was calculated. Mass of dry matter (figure 11) ranges from 3.08 t/ha to 6.96 t/ha with exception of sample plot with older, multiannual plants that had a 16.82 t/ha dry mass production. Average density (figure 10) of fresh indigobush samples was 0.80 g/cm3.
For comparison, average moisture content of oak and ash young plant was 40.64% in wintertime and 51.51% in summertime. Biomass production was 5.46 t/ha. Average density of fresh oak and ash samples was 1.09 g/cm3.

Key words: indigobush; biomass; production; moisture content; dry mass; density
