Disappearance Of Residual Dry Matter On Annual Grassland In The Absence Of Grazing, W. E. Frost, J. W. Bartolome, K. R. Churches

IGC Proceedings (1997-2023)

Residual dry matter (RDM) is a standard used by grassland managers for assessing the level of grazing use on annual grasslands and associated savannas and woodlands. Residual dry matter is the old plant material left standing or on the ground at the beginning of a new growing season. It indicates the combined effects of the previous season's forage production and its consumption by grazing animals of all types. The standard assumes that the amount of RDM remaining in the fall, subject to site conditions and variations in weather, will influence subsequent species composition and forage production, in addition to providing …

Yield And Composition Of Forage Maize: Interaction Of Harvest Date, Cultivar And Plastic Mulch, E. M. Little, P. O'Kiely, J. C. Crowley, G. P. Keane

IGC Proceedings (1997-2023)

Forage maize is established as a crop with the potential to consistently supply high yields of quality forage on some Irish farms. Despite its success, considerable variability in crop yield, quality and maturity at harvest can exist from year to year. These reflect differing prevailing weather conditions, particularly temperature during May to September. The use of plastic mulch has increased the likelihood of achieving higher yields of high quality crops and has permitted maize production to extend into areas once considered unsuitable for the crop. In this experiment two cultivars of differing maturity were grown with or without plastic mulch …

Cob Development In Forage Maize: Influence Of Harvest Date, Cultivar And Plastic Mulch, E. M. Little, P. O'Kiely, J. C. Crowley, G. P. Keane

IGC Proceedings (1997-2023)

Forage maize grown for silage tends to be a compromise between reproductive and vegetative yield, and the cob component is the main driver of feeding value (Keane et al., 2003). Thus the aim is to produce a well-developed crop of high dry matter (DM) and starch content reflecting large cobs of well-filled grains rather than crops with low DM and starch contents reflecting poorly developed (immature) cob components at harvest. The use of plastic mulch can increase total DM yields with the increase in cob yield accounting for 75% of the total yield increase (Easson & Fearnehough, 1997). In …
