Breeding for Disease Resistance in the Major Cool-Season Turfgrasses
Annual Review of Phytopathology, 2006Abstract Over the past several decades, breeding cool-season turfgrasses for improved disease resistance has been the focus of many turfgrass breeding programs. This review article discusses the dramatic improvements made in breeding Kentucky bluegrass (Poa pratensis) for resistance to leaf spot (caused by Drechslera poae), stem rust (caused by ...

This chapter discusses: (1) how cool season grass cover crops affect soil properties, nutrient cycling, pest and disease control, weed control, and subsequent cash crop yields, and (2) key issues or challenges in integrating grass cover crops into crop rotations. Because soil erosion control benefits of cover crops are relatively well known, especially

Cool-season leguminous cover crops
Legumes add nitrogen (N) to agricultural systems via the process of biological nitrogen fixation (BNF). They have long been integrated into crop rotations as forage and cash crops, with increasing adoption as cover crops in recent years. This review explores the role of cool-season legumes as cover crops while also examining the potential for ...Artie Siller +2 more

Cool-Season Turfgrass Reseeding Intervals for Methiozolin
Weed Technology, 2012Methiozolin selectively controls annual bluegrass in cool-season turfgrasses, and practitioners may wish to reseed desirable species in treated areas. Field experiments were conducted to evaluate reseeding intervals for creeping bentgrass, perennial ryegrass, and tall fescue following methiozolin applications. Turfgrass establishment varied for species,

Cool‐season turfgrass: estimating water use
Journal AWWA, 1996With these coefficents, engineers can estimate evapotranspiration and water needs for turfgrass.Consumptive‐use coefficients for cool‐season turfgrass have been developed using the Penman‐Monteith and United Nations Food and Agriculture Organization Blaney‐Criddle equations.

SILICON FERTILIZATION IN COOL-SEASON TURFGRASSES
Previous studies of the benefits of silicon (Si) supplementation in turfgrass have yielded inconsistent results. This dissertation aimed to assess the benefits if Si supplementation in cool-season turfgrass under more well controlled conditions than many previous studies.openaire +1 more source
Urea nitricphosphate for cool‐season grass production
Communications in Soil Science and Plant Analysis, 1993Abstract Significant losses of nitrogen (N) can occur via volatilization of ammonia (NH3) when non‐incorporated broadcast applications of urea or urea‐containing fertilizers are made. This study was conducted to determine the efficacy of urea nitricphosphate (UNP) as an N and phosphorus (P) source for cool‐season grasses and to evaluate NH3 ...

Genome Mapping in Cool-Season Forage Grasses
2008Molecular markers, specifically SSR markers, have found wide utility in genomic research. However, in forage grasses, the availability of such markers restricts and restrains the breeder/geneticist from taking full advantage of this frequently utilized technology.

THE COOL-SEASON TROPICAL DISTURBANCES OF SOUTHEAST ASIA
Journal of Meteorology, 1955Abstract During the cool season (November through April), two types of tropical disturbance occasionally bring rain to a normally dry part of southeast Asia. The area, enclosed approximately between 15°N and 25°N, and 95°E and 120°E, includes south China and the northern portions of Indo-China and Thailand.

Cool season cyclogenesis and associated mesoscale weather
Reviews of Geophysics, 1995The modernization of the National Weather Service (NWS) and a profusion of recent field experiments (Table 1) are bringing an explosion of mesoscale observations to the meteorological community during the 1990's. (The term “mesoscale” used in this paper refers to horizontal dimensions ranging from a few tens of kilometers to a few hundred kilometers ...
