Seeding is the most common establishment method used for turf areas ( Christians, 1998 ). Seeding keeps establishment costs to a minimum ( Burton, 1992 ) and is convenient because of the ease of transportation, storage, and spreading of seeds
et al., 1993 ). Most buffalograss is commercially treated with KNO 3 followed by chilling to overcome dormancy ( Fry, 1995 ), which increases germination from 10% to 80% ( Riordan et al., 1997 ). Optimum spring seeding dates for buffalograss

Plants produce seeds to ensure the greatest establishment and survival success for future generations ( Stoehr and El-Kassaby, 2011 ). One innate mechanism to increase seedling success is seed dormancy. The critical function of dormancy is to

Stanhay, Carraro, and Gaspardo precision vegetable seeders were evaluated for seeding uniformity with seeds of five vegetable crops—cabbage (Brassica oleracea L. Capitata group), carrot (Daucus carota L.), cucumber (Cucumis sativus L.), onion (Allium cepa L. Cepa group), and spinach (Spinacia oleracea L.). Five measurements [mean, percentage of misses, percentage of multiples, quality of feed, and precision (defined as the coefficient of variation after misses and multiples were discarded)] were used to evaluate seeder uniformity. Using all five measurements provided a more complete determination of the metering uniformity of the seeders than was possible in prior work when only mean and coefficient of variation were used. The belt seeder (Stanhay) was effective at singulating spherical seeds (cabbage) and nearly spherical seeds (onion)as the most precise vacuum seeder (Carraro). Seeding uniformity of all seeders with elongated (carrot and cucumber) or angular (spinach) seeds was inadequate for precision seeding.
( Zuk and Fry, 2005 ). Bermudagrass is used extensively in the transition zone, but until recently there were no seeded turf-type cultivars that had acceptable freezing tolerance. ‘Yukon’ bermudagrass was released in 2002 by Oklahoma State University
