Impact Of Nitrogen Rate In Conventional And Organic Production Systems On Yield And Bread Baking Quality Of Soft Red Winter Wheat, Ammar Al-Zubade, Timothy D. Phillips, Mark A. Williams, Krista L. Jacobsen, David Van Sanford Aug 2021

Impact Of Nitrogen Rate In Conventional And Organic Production Systems On Yield And Bread Baking Quality Of Soft Red Winter Wheat, Ammar Al-Zubade, Timothy D. Phillips, Mark A. Williams, Krista L. Jacobsen, David Van Sanford

Plant and Soil Sciences Faculty Publications

Soft red winter wheat (SRW) is characterized by high yield and relatively low protein content. In Kentucky, there is growing demand from local artisan bread bakers for regionally produced flour, requiring production of grain with increased protein content and/or strength. The objective of this two-year field experiment was to evaluate the effect of nitrogen (N) management on five cultivars of winter wheat on yield and bread baking quality traits of modern and landrace SRW cultivars (Triticum aestivum L.). All five cultivars were evaluated using two N application rates in conventional and organic production systems. All traits measured were significantly …


Tropical Legumes To Augment Forage Yield In The Eastern Caribbean, E. Valencia, M. B. Adjei Aug 2021

Tropical Legumes To Augment Forage Yield In The Eastern Caribbean, E. Valencia, M. B. Adjei

IGC Proceedings (1977-2023)

Little information is available on the contribution of tropical legumes to forage yield in the eastern Caribbean. This study assessed the effects of three grazing cycles (GC; 5, 10 and 15-wk) on seasonal dry matter (DM) yield of binary mixtures of the tropical legumes glycine (Neonotonia wightii) and desmanthus (Desmanthus virgatus) with “Bambatsi” (Panicum coloratum) and “Mottgrass” (Pennisetum purpureum Shum.). Plant responses were assessed by mob-grazing with sheep (12-24 hrs; to average stubble height of 15-cm) for each GC. Grazing cycles affected yield of both the legume and grass component (P< 0.05). At GC of 5-weeks, forage DM ranged from 1.5-2.0 Mg ha-1 in …
