Tall fescue (Festuca arundinacea Schreb.) is an important forage resource for beef (Bos taurus L.) production in the North–South transition zone. Recently, the cultivar ‘Jesup’ was released to provide improved stand survival when infected with a novel (nontoxic) endophyte marketed as MaxQ (Pennington Seed, Madison, GA), and warrants evaluation as a source of winter hay for beef cattle.

Plants require nitrogen (N) to make proteins, nucleic acids and other biological molecules. It is widely accepted that plants absorb inorganic forms of N to fill their needs. However, recently it has become clear that plants also have the capacity to absorb organic N from soils. In this paper we describe a new kind of symbiosis involving seed-vectored rhizobacteria and grasses that is targeted ...

Fresh, senesced, and decaying pine needles from Pinus halepensis were evaluated for their allelopathic potential on Festuca arundinacea, Cynodon dactylon and the biosensor plants Avena sativa and Lemna minor through in vivo and in vitro studies. The in vivo study was performed in growth chambers, using 6, 12, and 18 g of pine needle tissue mixed with screened perlite as a substrate. The effects...

Infrequently mowed grass areas on institutional grounds and golf courses can reduce mowing costs impart a natural appearance to the property. However, weed encroachment into these compromise aesthetic appeal of stand increase associated with control. The objective this 2-yr field study was determine influence species frequency cover quality. Six or mixtures were established from seed subjected ...
