This study was carried out to compare in situ and in vitro enzyme techniques for determining estimates of forage escape proteins. Eight forages (vetch hay, wheat silage, corn silage, wheat hay, grass hay, lentil straw, triticale hay and alfalfa hay) were used as feed materials. During 70 h, incubation with enzyme method had similar escape protein values for vetch hay, wheat hay, grass hay, trit...

Legume–grass mixture can greatly improve soil fertility to support the sustainable productivity. Root litter is an important source of organic matter, but its link with nutritional status in forage mixtures not clear. This study was aimed uncover whether relationship carbon (C) and nutrients between root would change mixing ratio. Changes C, nitrogen (N), phosphorus (P) were studied a 2-year ex...

Cover crops (CC) have great potential to enhance the sustainability of agroecosystems. However, wide range possible rotations CC and cash (CaC) means that important knowledge gaps persist on how affects CaC. We investigated legacy effects five common (three monocultures: vetch, melilotus, barley, two mixtures: barley-vetch barley-melilotus) most CaC, maize wheat. A microcosm, semi-controlled ex...

Some growth parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the Institute of Forage Crops, Pleven, Bulgaria. Humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. Ratios of aboveground weight t...
