Abstract

The aim of the study was to determine the optimum sowing density and nitrogen
fertilization for hemp cultivar Kompolti grown for stem. The investigations were carried
out by means of field experiments on the College of Agriculture in Križevci
experimental station in years 2003., 2004. and 2005. The Hungarian cultivar Kompolti
was used in the experiment.
Three different sowing densities (100, 200 and 300 viable seeds/m2) and four
nitrogen rates (0, 60, 120 and 180 kg N/ha) were investigated in the experiment. The
experiment was set according to the split-block method in five replications.
Cultivar Kompolti achieved very high total biomass and air-dry stems yield
(average 34.6 t / ha and 14.3 t / ha) in all three climatically very different experimental
years.
The results of the study show that in order to achieve high yields of the stem 300
viable seeds/m2 should be sown and fertilized with 180 kg N/ha, if quantity and quality
of fiber is not important.
