Timely Autumn Seeding Of Annual Ryegrass Is Essential For High Yield, Jennifer M. Johnson, Edzard Van Santen

IGC Proceedings (1977-2023)

The use of annual ryegrass (Lolium multiflorum Lam.) as a winter cover crop and grazing option in the Southeast Unit-ed States has become a common practice. Recent research evaluating the effects of seeding time on seed yield in Canada determined autumn seeding produces the most desired results relative spring seeding, but indicated that varied autumn seeding rates would further their findings (Coulman et al. 2013). A University of Arkansas study utilized cool season annuals, wheat (Triticum aestivum L.) and annual ryegrass, to evaluate animal performance and seeding date effects. This research indicated that seeding cool-season annuals in …

New Herbaceous Perennial Legumes In Dryland Mediterranean Agroecosystems: Pasture Persistence And Productivity, Viviana Barahona, Carlos Ovalle, Alejandro Del Pozo, Soledad Espinoza, Fernando Squella, Fernando Fernandez, Macarena Gerding

IGC Proceedings (1977-2023)

One of the strategies to improve pasture and crop productivity in the Mediterranean zone of Chile has been the introduction and use of annual legumes (del Pozo and Ovalle 2009; Ovalle et al. 2010). The growth rate of annual legumes is low during autumn and winter, and the distribution of the biomass production is mainly concentrated in spring when temperatures are moderate and soil water is available. It is hypothesized that perennial deep-rooted legumes can play a key role in improving soil physicochemical characteristics as well as water-use efficiency (Cocks 2001; Dear et al. 2003; Ward 2006).

Physiological Characterization Of Cut-To-Cut Yield Variations Of Alfalfa Genotypes Under Controlled Greenhouse Conditions, Defeng Li, Baoluo Ma, Chengzhang Wang, Pufang Li Dec 2019

Physiological Characterization Of Cut-To-Cut Yield Variations Of Alfalfa Genotypes Under Controlled Greenhouse Conditions, Defeng Li, Baoluo Ma, Chengzhang Wang, Pufang Li

IGC Proceedings (1977-2023)

In a temperate region, alfalfa (Medicago sativa) crops are usually harvested 3-6 times per annum. The biomass yields of first and second cuts in the spring are generally the high-est. However, in subsequent cuts the biomass yields decline, with the final 1 or 2 cuts producing the lowest yields (Wang et al. 2009). This seasonal reduction in alfalfa biomass yields could be associated with prevailing changes in environmental factors such as rainfall and heat stress or due to biological characteristics of alfalfa crop itself. In this study, alfalfa was grown under controlled greenhouse conditions with suitable temperature, …

Trifolium Occidentale: A Valuable Genetic Resource For White Clover Improvement, Syed Wajid Hussain, Warren M. Williams Dec 2019

Trifolium Occidentale: A Valuable Genetic Resource For White Clover Improvement, Syed Wajid Hussain, Warren M. Williams

IGC Proceedings (1977-2023)

Trifolium occidentale Coombe is a stoloniferous, diploid (2n=2x=16) perennial clover indigenous to Portugal, Spain, France, and the British Isles. It grows in relatively dry coastal habitats, in sand dunes and on shallow pocket of soil (Coombe 1961; Coombe and Morisset 1967). As the species grows naturally in saline, dry habitats, it is potentially a source of drought tolerance genes that could be used for the improvement of white clover (Trifolium repens L.) cultivars. Although T. occidentale is reported to be one of the progenitors of white clover (Williams et al. 2012), the 2x forms of T. occidentale cross …

Dry Matter Yield Of Perennial Ryegrass Cultivars Under Mechanical Cutting And Animal Grazing, Patrick A. Cashman, Trevor J. Gilliland, Michael O’Donovan, Marion Beecher, Mary Mcevoy

IGC Proceedings (1977-2023)

Perennial ryegrass evaluation trials are essential to identifying and promoting the most productive cultivars for use at farm level to maximise sward productivity (Grogan and Gilliland 2011). Cultivar testing is predominantly conducted under simulated grazing trials to predict dry matter yield (DMY) performance under animal grazing. Previous studies have shown a high correlation in DMY between these two defoliation methods (Camlin and Stewart 1975; Creighton et al. 2010). In contrast, Binnie and Chestnutt (1991) demonstrated that swards grazed by animals had higher DMY performance than those exposed to simulated grazing managements. Animal pressures such as pulling, treading and nutrient …
