Abstract: The aim of this study is to analyze the dry matter yield of morphological components of sideoats grama (Bouteloua curtipendula (Michx.) Torr). The 7 genotypes of sideoats grama identified with numbers 5, 62, 125, 181, 303, 357, 417 and the commercial variety El Reno were used. The 6 destructive samplings were made at 50, 65, 80, 95, 110 and 125 days after sowing (das) to 5 plants (replicates) per genotype. Statistic differences were observed in all of the variables for leaf dry matter (mg/DM/plant) between genotypes differences (p<0.01) were observed. For 125 das, genotypes 303, 357 and 5 exceeded the variety El Reno in 3.9, 3.8 and 3.5 magnitudes, respectively. Genotypes 62 and 181-125 das showed greater amount of stem respect to other morphological components and genotypes (p<0.01). Genotype of 125-125 das produced higher proportion of leaf compared to previous dates (p<0.01). It is concluded that by the differences between genotypes, being young plants, the outstanding plants will have greater ability to photosynthesize more nutrients which will be reflected in a better adaptation to the establishment.
