A study was conducted in a pure stand of lucerne (variety Viktoria) under natural weed
infestation with shepherd’s purse (Capsella bursa pastoris (L.) Medic.) on a slightly leached
chernozem soil under nonirrigated conditions in the experimental field of the Institute of
Forage Crops – Pleven during the 2006-2007 period.
The effect of shepherd’s purse Capsella bursa pastoris (L.) Medic. on the chemical composition
of lucerne Medicago sativa (L.) was analyzed.
Statistically significant (P<0.05) functional relations were found between the chemical
characteristics and percentage of Capsella bursa pastoris (L.) Medic. participation in the
lucerne sward, and forage quality. These relations indicated a multiple practical relevance
and a necessity to control Capsella bursa pastoris (L.) Medic. in lucerne stands in order to
decrease weed density and improve forage quality. Tokom perioda 2006-2007. godine obavljeno je istraživanje na eksperimentalnom polju
Instituta za krmno bilje u čistom zasadu lucerke (varijetet Viktoria) sa prirodnom zakorovljenošću
rusomačom (Capsella bursa pastoris (L.) Medic.) na blago izluženom černozemu u
uslovima bez navodnjavanja.
Analiziran je efekat rusomače Capsella bursa pastoris (L.) Medic. na hemijski sastav lucerke
Medicago sativa (L.).
Konstatovani su statistički značajni (P<0,05) funkcionalni odnosi između hemijskih osobina
i procenta učešća Capsella bursa pastoris (L.) Medic. u lucerki, i kvaliteta krmiva. Ovi odnosi
ukazuju na višestruku praktičnu važnost i potrebu suzbijanja vrste Capsella bursa pastoris
(L.) Medic. u lucerki kako bi se smanjila gustina korova i poboljšao kvalitet krmiva.
