Abstract :To investigate the effect of seed origin on the nutritive value of narrowleaf birdsfoot trefoil insert ignore into journalissuearticles values(NBT, Lotus tenuis Waldst.&Kit.);, seeds of 86 NBT populations were collected from plants spontaneously occurring in natural pastures and rangelands located at different geographical gradients of the Black Sea Region, Turkey. Some nutrient contents of these populations regrown under the same conditions were determined. Minimum and maximum values with regard to the crude protein insert ignore into journalissuearticles values(CP);, acid detergent fiber insert ignore into journalissuearticles values(ADF);, neutral detergent fiber insert ignore into journalissuearticles values(NDF);, Ca, P, Mg, K and condensed tannin contents, relative feed value, Ca P-1 and K insert ignore into journalissuearticles values(Ca+Mg);-1 ratios were found as 176.83 and 238.87, 201.00 and 351.61, 307.19 and 435.48, 15.01 and 21.60, 2.18 and 3.77, 3.03 and 4.02, 8.43 and 16.69, 20.00 and 31.50 g kg-1 dry matter, 189.70 and 263.41, 4.73 and 9.57, 0.35 and 0.88, respectively. The effects of seed genotype from different altitudes insert ignore into journalissuearticles values(Ca P-1);, latitudes insert ignore into journalissuearticles values(digestible dry matter and ADF); and longitudes insert ignore into journalissuearticles values(CP and Mg); on some nutrient contents and feed values were found significant insert ignore into journalissuearticles values(P<0.05);. The correlations between altitude and NDF, P and Mg or between latitude and P and Mg contents of populations were significant. There were no specific trends in chemical composition and the nutritive value of tested NBT populations due to geographical variation. Thus, the results suggested that all studied geographical populations can be selected to obtain the nutritionally superior forage.
