Growing concern over the sufficiency and variability of present water supplies in the arid Southwest has led to the examination of buffalograss [Buchloe dactyloides (Nutt.) Engelm.] for water conservation. Increasing acceptance of buffalograss will require investigation into conversion techniques for its establishment. The objectives of this study were to evaluate the effects of seedbed preparation and seeding rate on the establishment of buffalograss after bermudagrass desiccation with glyphosate. Research was conducted at the Texas Tech Quaker Research farm in 2009 and 2010 on a mature ‘Riviera’ common bermudagrass [Cynodon dactylon (L.) Pers.] rough. Bermudagrass was sprayed with glyphosate at 1.1 kg acid equivalent (ae)/ha 5 and 1 weeks before seedbed preparation. Plots were scalped after desiccation. Treatments were arranged in a two × four factorial, randomized complete block design with four replications. two buffalograss seeding rates and four seedbed preparation treatments. Seedbed preparation treatments consisted of no seedbed preparation, topdressing alone (0.6-cm layer), hollow-tine aerification + topdressing, or verticutting + topdressing. ‘TopGun’ buffalograss was planted on 1 June 2009 and 4 June 2010 at 146 or 195 kg·ha−1. Grid counts were conducted to determine buffalograss cover one, two, and three months after planting (MAP). Counts were then converted to percent cover (0% to 100%). Greater buffalograss cover was observed when seed was applied at the higher rate (196 kg·ha−1) except within treatments that did not receive seedbed preparation treatment. No seedbed preparation resulted in unacceptable buffalograss cover. Percent buffalograss cover three MAP was 75%, 83%, and 86% for topdressing alone, aerification + topdressing, and verticutting + topdressing treatments seeded at 195 kg·ha−1, respectively.

A 2001 survey of 102 nurseries that were members of the Georgia Green Industry Association was conducted to assess irrigation practices of container ornamental nurseries. Mean nursery size was 64 acres (26 ha) and mean annual revenue was about $3 million. About 50% of the irrigation water was from wells and the other 50% came from surface sources, such as collection basins. Irrigation in smaller containers, including #1, #3, and #5, was applied primarily by overhead methods, while larger containers (#7, #15, #25) made extensive use of direct application methods, such as drip or spray stakes. Frequency of irrigation in the summer growing months was about three times that of the winter season. Georgia nurseries use irrigation practices suggested in Southern Nursery Association best management practices, including collection of runoff water (48%), cyclic irrigation (44%), watering in the morning (92%), and grass strips between the production beds and drainage areas (60%).

A survey was conducted of nursery operators participating in workshops in west-central Florida. The purpose of the survey was to identify the irrigation best management practices (BMPs) adopted by container nurseries in west-central Florida and obtain information regarding emphasis of future extension educational programs. Workshops were conducted in Hillsborough County, Fla., and Manatee County, Fla., and participation was voluntary. Respondents were asked about BMPs used in the nurseries according to the irrigation system used and it was found that the majority of the nurseries relied on well water as the primary source for irrigation. While 69% of the nurseries monitored uniformity of microirrigation systems, only 35% monitored uniformity of overhead irrigation systems. Thirty-four percent of the nurseries collected irrigation or rain runoff and 9% knew the water holding capacity of their substrate. Most of the nurseries grouped plants by irrigation requirements (74%) and grouped container sizes by irrigation requirements (69%). The survey indicates that many BMPs are not widely adopted by nurseries in west-central Florida. The information from this survey can be used as a guide to focus the efforts of university extension educational programs to achieve greater adoption of BMPs.
