A Comparative Study on the Characteristics of Seeds and Phytomass of New High-Potential Fodder and Energy Crops

The purpose of this research is to capitalise on the potential non-traditional plant species in Republic Moldova from families Asteraceae (cup Silphium perfoliatum; cardoon Cynara cardunculus), Fabaceae (fodder galega Galega orientalis, sand sainfoin Onobrychis arenaria), Hydrophylaceae (phacelia Phacelia tanacetifolia), Malvaceae (curly mallow Malva crispa; Virginia Sida hermaphrodita) and Poaceae (perennial sorghum Sorghum almum, pearl millet Pennisetum glaucum). study presents results seed properties (dimensional parameters, structure, friability, apparent specific mass, mass 1000 seeds) phytomass quality above-mentioned plants. obtained demonstrate that criterion dimensional proportionality Kdp, proposed paper, effectively reflects structure seeds; seeds new crops (except phacelia) have high friability (angle repose α ≤ 33° angle static friction steel α1 27.8°, wood = 34.7°, enamelled surface 30°). natural fodder researched characterised by a crude protein content 9.0–23.4%, dry matter digestibility 56.0–66.5%, digestible energy load 11.16–12.95 MJ kg−1, metabolizable 9.16–10.63 net for lactation 5.18–6.76 relative feed value RFV 74–129. biochemical biomethane studied vegetal substrates 297–353 l kg−1 VS.
