Dry matter accumulation and forage quality characteristics of different soybean genotypes

摘要: Three different soybean [Glycine max (L.) Merr.] cultivars (A-3127, Derry, and Yemsoy) were evaluated for dry matter (DM) yield, plant components, crop growth rate (CGR) at row spacings harvesting stages in 3 locations with Mediterranean-type climate a split-split plot design replications 2009 2010. In addition, crude protein (CP), yield (CPY), acid detergent fiber (ADF), neutral (NDF), total digestible nutrients (TDN), relative feed value (RFV) of harvested forage soybeans determined the Bursa (Turkey) location. Increased significantly reduced DM all locations. Combined over other main effects, 25-cm spacing produced 35% more than 75-cm spacing. Row greatly affected R5 particularly R7 stage, but this effect was minimal R1 stage. The forage-type cultivar Derry higher locations, stages. constituent components similar cultivars. general, CGR decreased from to varied according harvest period, spacing, had Antalya Quality characteristics not by showed little cultivar. Harvest stage CP, ADF, NDF, TDN, RFV concentrations forage. It concluded that Mediterranean environments (i.e. Derry) can be seeded narrow rows (25 cm) high population (100 kg ha-1) offer most when later R (e.g., R7) rather early reproductive
