The invasion of Eragrostis lehmanniana Nees in rangelands of Chihuahua, Mexico, has resulted in a need for revegetation to recover lost forage productivity. Thus, new knowledge on generating alternatives to improve these invaded grasslands is of great importance. This study evaluated seedbeds prepared with unconventional tillage implements and seeded with a grass mixture to reduce the plant density of E. lehmanniana while increasing the productivity of an invaded semiarid grassland of Chihuahua. The unconventional tillage implements were: Rangeland Harrow, which were used to prepare the Striped Harrowing and Full Harrowing seedbeds; Rangeland Rehabilitator, which prepared a Deep-Stingray Subsoiler seedbed; and a Tandem-type Aerator Roller, which prepared a Double-Digging Aeration seedbed. An area without tillage was left as control. The seed mixture was composed of Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths, var. Hachita (25%); Bouteloua curtipendula (Michx.) Torr., cultivar-6107 Kansas (25%); Leptochloa dubia (Kunth) Nees, var. Van Horn (5%); Eragrostis curvula (Schrad.) Nees var. Ermelo (40%), and Sorghum almum Parodi (5%). The experiment was conducted during four years and the evaluation started at the second year. Plant density and dry matter (DM) production was evaluated per species. In the control plot, the plant density of E. lehmanniana increased approximately 180% from the 2nd to the 4th year (18 to 50 plants m-2). The use of unconventional tillage implements for seedbed preparation and the inclusion of E. curvula in the seed mixture, decreased E. lehmanniana density in more than 50% and increased DM production in more than 100%. Considering the whole experimental period an all the prepared seedbed treatments, E. curvula had the highest establishment and DM production of all the seeded species. The native species B. gracilis, B. curtipendula and L. dubia had a poor establishment in all the prepared seedbeds.
