Cover Crop Systems Impact on Biomass Production, Carbon-to-Nitrogen Ratio, Forage Quality, and Soil Health Indices in a Semiarid Environment.
… greater above- and below-ground biomass and forage nutritive value and lower tissue carbon-to-nitrogen (C/N) ratios. We also hypothesize that these characteristics will promote greater soil organic carbon, total nitrogen, and microbial biomass and diversity compared to cover crop …

Forage Utilization and Nitrogen Management of Tall Fescue Stockpiled for Winter Grazing
… and how grazing methods impact weight gains, forage utilization, and forage nutritive value. The first study evaluated the impact of N rate and source on the yield tall fescue stockpiled for winter grazing. In mid-September, seven N sources (ammonium sulfate (AS), ammonium nitrate (AN), urea + …

Hair Sheep Production in Temperate, Deciduous Appalachian Silvopastures
… different deciduous tree species are available. Forage and animal performance was compared from open systems (i.e., no trees) with that from silvopastures containing 13-yr-old honeylocust (Gleditsia triacanthos) or black walnut (Juglans nigra) trees. Cool-season grass-legume pastures were …

Diversity Relationships in Native, Warm-Season Plant Communities used for Agriculture
… that diverse mixtures of plants may improve forage productivity and also be suitable as bioenergy crops. The objectives of this research were: 1) to measure the effects of native, warm-season perennial (NWSP) forage mixtures and management methods on productivity, weed biomass, nutritive …

Linking Cattle, Forage, and Tree Production in Silvopastures
… is the intentional integration of trees with forages and livestock. In Blackstone, Virginia a silvopasture management plan was created in a thinned, timber stand seeded with a cool-season forage mixture. Treatment pastures for this study included an open pasture, a thinned pine silvopasture, a …

Mob stocking effects on herbage nutritive value, herbage accumulation, and plant species composition
… but was hypothesized to diminish the nutritional value of herbage relative to continuous and rotational stocking with lesser stocking density at similar stocking rates. This thesis summarizes two studies conducted in Blacksburg and Raphine, and in Steeles Tavern, VA, respectively, at a single beef …

Effect of replacing nitrogen fertiliser with gibberellic acid on response of perennial ryegrass and white clover pasture : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… ryegrass tiller size and density and forage nutritive value. To test these results, several treatment regimens were compared in a grazing trial with dairy cows which explored milk production and N excretion. Using a randomised block design with ten treatment regimens and four blocks, …
