Chemical composition of forage crops (35% hungarian vetch, 35% forage peas, 10% oats, 10% triticale, 10% wheat) of different harvest times and fertilizer applications at different doses, relative feed value (RFV), relative feed quality (RFQ , energy contents (ME, NEL), in vitro digestibility parameters (TNDFD, TOMD, TDN, DMI), in vitro gas production, methane (CH4) production, fractionation factor (PF), microbial protein (MP) and microbial protein synthesis efficiency Ankom Daisy in vitro fermentation system and in vitro gas production technique were used in the research carried out to determine their effects on (MPSE) and true degree of digestion (TDD). Harvesting at different times significantly affected (P<0.05) the CP (crude protein), CC (crude cellulose), RFV, RFQ, ME and NEL, TNDFD (true NDF digestion), TOMD (true organic matter digestion), TDN (total digestible nutrients), DMI (dry matter intake), GP (gas production), Methane (ml), TDCM (true digestible dry matter) and TDD values of the mixture. The effects of different amounts of urea and DAP (Diammonium Phosphate) applications on the nutrient values of the forage plant mixture RFV, NEL, TNDFD, TOMD, TDN, DMI, RFQ and gas production, microbial protein and actual digestion degree parameters were found to be significant (P<0.05). It was determined that 10 kg of DAP + 10 kg of urea and only 20 kg of urea per decare gave better results than other applications. As a result, it was determined that harvesting at different times and fertilizer applications at different doses contributed to the chemical composition and digestibility of the mixture, improving the feed quality in terms of relative feed quality and value, and reducing gas production in the early harvest period.
