Abstract
White lupin (Lupinus albus L.) is not widely known
in Serbia. A small-plot trial was carried out during
2006 and 2007 at the Rimski Šancevi Experiment
Field of the Institute of Field and Vegetable Crops,
on a carbonated chernozem soil with a pH value in
H₂O of 7.92. It included twelve white lupin
accessions of diverse geographical origin from the
Annual Forage Legumes Collection of the Forage
Crops Department of the Institute. All accessions
were sown in early March, with a crop density of
75-85 viable seeds m⁻², and were cut when main stem
inflorescences were in full flower. The tallest
accession was Termis (120 cm). The greatest number
of main stems and first-order branches was in
BG-005542 (9.0 plant⁻¹) and BG-002171 (8.7 plant⁻¹),
with the former having most leaves as well
(59.7 plant⁻¹). Accessions BG-005542 and LUP 261/89
had the highest green forage yields of 53.3 t ha⁻¹ and
52.9 t ha⁻¹ respectively. The average dry forage
matter yield ranged from 4.0 t ha⁻¹ in BG-002173 to
8.7 t ha⁻¹ in Termis. The greatest dry matter
proportion in green forage was in Termis and
Siebacher Red (0.19).
