Revegetation of Retired Farmland: Response of Range Grasses to Establishment Irrigations and Microcatchment Water HarvestingThacker, G.; Cox, J.; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1988-09)In July 1987, an experiment was initiated to evaluate the effects of water harvesting and establishment irrigations on the establishment and persistence of buffelgrass, kleingrass, and sideoats grama grass on retired farmland A density evaluation in November 1987 revealed a significant increase in percent cover of the grasses due to establishment irrigations. No significant differences were detected among water harvesting treatments or flat- disked controls. Evaluations will continue to measure any long-term effects from these treatments.
Revegetation of Retired Farmland: Response of Fourwing Saltbush to Establishment Irrigations and WeedingThacker, G.; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1988-09)Fourwing saltbush (Atriplex canescens) was seeded in 80 -inch wide water harvesting microcatchments on retired farmland west of Tucson. Eight months after planting the plots that had received one establishment irrigation and weeding had significantly more cover than the unirrigated and unweeded treatments. The percent cover of the uninigated /weeded and irrigated /unweeded treatments was not significantly different. Uninigated and unweeded plots had virtually no cover of saltbush. It appears that establishing saltbush in microcatchments of this size is not feasible without either an establishment irrigation or weed control.
