Phyto-Ruminal-Bioremediation: Grasses To The Rescue, Morrie Craig, Jennifer Duringer, Linda Blythe

IGC Proceedings (1997-2023)

The US EPA has defined Super Fund sites for 594 toxins in the United States. The EPA definition of toxins is one that causes acute or chronic human health effects, or causing significant environmental harm. One of the categories of toxins is nitroaromatic molecules, which are used primarily as munitions. In the United States alone there are 16,000 Department of Defense (DoD) sites. The most common munitions there are TNT, RDX, HMX, and 2,4 DNT. In the world, these sites range historically from World War II residues to those from recent Middle East conflicts. Human health effects from these toxins …

Selection Of Suitable Varieties Of Grasses For Myanmar, Nang Khan Hline, Khin San Mu, Moe Thida Htun, Lwin Naing Oo, Soe Min Thien, Dezin Soe Lwin, Jue Jue, Aung Aung, Jenny Hanks, Werner Stür, Ganda Nakamanee

IGC Proceedings (1997-2023)

The basal feed resources for ruminants available in most developing countries in the tropics are crop residues, pasture from infertile land, for example communal land, or agro-industrial by-products. These are low in protein and of low digestibility. A major problem facing livestock producers in tropical areas is proper nutrition for their animals during the dry season when pastures, cereal residues and maize stover are limiting in nutritional quality. The researchers in Myanmar have tried to improve the nutritive value of fibrous agricultural residues. Aung Aung et al. (2006) supplemented the sesame and chickpea husk to bulls fed on urea-treated …

Productive Longevity Of Fodder Galega-Grass Swards, Aleksandrs Adamovics, Olga Adamovica, Iveta Gutmane

IGC Proceedings (1997-2023)

Red clover, alfalfa and white clover are traditional forage crops in Latvia. In Latvian agricultural practice, fodder galega (Galega orientalis Lam.) is grown for a relatively short period. Recently introduced into Latvia, it is rousing evergrowing interest due to its persistency and high yielding ability. Experiments on fodder galega show that this longlived legume survives in pure stands for 25 and more years and provides annual DM yields from 9.56 to 11.0 t ha^-1 (Adamovics and Auzins, 2006; Slepetys, 2000; Slepetys and Adomovics, 2011). Pure fodder galega stands, compared to other legumes, are not thinning out during harvest …

IGC Proceedings (1997-2023)

This paper reviews the experience of ecological restoration adopted by Bharat Coking Coal Limited (BCCL), a Miniratna Company, a subsidiary of Coal India Limited, Government of India, Public Sector Undertaking to restore the mined out degraded land in Jharia Coalfield (JCF). JCF is one of the oldest coalfield of India and was mined in an unscientific manner for more than 100 years by the erstwhile private entrepreneurs until it was nationalised in 1972-73, due to which the coalfield was subjected to severe land degradation, mine fires and subsidence. The total degraded land in the JCF in 1986 was 6,294 hectares. …

The Role Of Botanical Garden Of Pbai In Bydgoszcz In Promoting The Crop And Usage Of Perennial C4 Grasses In Poland, Włodzimierz Majtkowski, Gabriela Majtkowska, Bartosz Tomaszewski

IGC Proceedings (1997-2023)

Among the over 300 grass species known from Poland, there are about 160 species well established in the flora (~130 native with C3 photosynthesis pathway and ~30 aliens), and nearly 150 ephemerophytes, occasional escapers from cultivation or cultivated species (Mirek and Piękoś-Mirkowa 2002). Grasses from other climatic zones have been introduced to our country in recent years, especially as ornamental plants and as a source of biomass for energy purposes. The studies conducted since the 1990s in Botanical Garden of PBAI in Bydgoszcz, where the National Grass Collection is located, have contributed considerably to the popularization of C4 grasses in …

Growing of various crops utilizing sewage is a common scenario in many urban and sub-urban areas. The crops mostly include forage crops, leafy vegetables, vegetables and sometimes food grains. These sewage waters are known to contain undesirable constituents like heavy metals, pesticide residues besides, harmful pathogens. These undesirable components can make way very possibly from sewage to soils, plant parts; there by to even milk, thus entering into food chain. Musi, a tributary of Krishna on whose banks Hyderabad lays is the main fodder bank of the city. Thousand of hactares of land resembling vast grassland ecosystem is under cultivation …

Yield And N Recovery By Grass Species In Response To Long Term Applications Of Manure And Mineral Fertilizer In A Cool Maritime Climate, Shabtai Bittman, Derek Hunt

IGC Proceedings (1997-2023)

Liquid manure is an important source of nutrients on many modern dairy farms. Nitrogen (N) use efficiency of slurry is usually less than chemical fertilizer, but the difference is less when tested in trials lasting at least 7 years than in short term trials (Schröder et al., 2007). The efficiency of slurry manure N can be improved by minimizing loss of ammonia after application using low emission applicators. In grass stands where injection is impractical, mitigation methods often involve spreading the slurry in narrow bands directly on the soil surface. Losses of N as ammonia, nitrous oxide and leaching have …

Effect Of Arbuscular Mycorrhize On Growth And Productivity Of Stylosanthes Seabrana, Neha Chakravarty, Ashok Shukla, Anil Kumar, S. K. Dhyani, Taru Nagori

IGC Proceedings (1997-2023)

Stylosanthes seabrana, an important range legume was introduced in India in the year 1998 through ACIAR-ICAR joint project. It has given good results under agroforestry/silvopastoral systems and can be grown as sole pasture crop or along with compatible grasses/legumes on a variety of soils. For its year round production, intensive cutting approach is generally employed. Under such conditions, plant demands large amount of soil nutrients for better productivity, which are generally applied as inorganic fertilizers (Chandra et al., 2006).

In soils with low nutrient contents especially phosphorus (P), large amount of phosphatic fertilizers are required for establishment and growth …

Macro Mineral Concentrations Of Five Contrasting Temperate Grassland Species Grown In Pure Stands Or Mixtures, Bodil E. Frankow-Lindberg

IGC Proceedings (1997-2023)

Mixtures of grassland species often results in over-yielding (Finn et al., 2013). This may be due to complementarity in traits above- and below-ground. Here I report the concentrations of macro minerals in five grassland species grown as pure stands or in mixtures in a field fertilized with moderate amounts of nitrogen (N).

In-Vitro Fermentation Study Of Some Grasses Utilized By Camels In Arid Ecosystem, Ashok Kumar Nagpal

IGC Proceedings (1997-2023)

Camel, the ship of desert feeds on a variety of feeds and fodders of grasses, crop residues and shrubs/bushes. The various types of feeds and fodders are the source of nutrient supply upon which depends the production performance of the animal. It is, thus, essential to create the data base of feeds and fodders and their nutrient contents for the formulation of balanced ration for the animals. The analysis of proximate components and detergent fibre components are generally done to get idea about the nutrient availability to the animal. In vivo evaluation provides the real picture of feeds and fodders …

Restoration Of Arid Grasslands: Issues And Strategies, R. K. Bhatt, M. P. Rajora, Ramavtar Sharma

IGC Proceedings (1997-2023)

Economy of the Thar Desert of India, lying between 24-29°N latitude and 70-76°E longitude, is closely linked with the raising of livestock which mainly depends upon the native rangelands for their sustenance. Pearl millet, moth bean, cluster bean, range grasses and legumes, trees and shrubs are the major components of arid ecosystem. Perennial grasses, viz., buffel grass, bird wood grass, sewan and gramna are the dominating pasture species of the region. Due to frequent droughts and overgrazing, the productivity of the natural grasslands of the region has been steadily decreasing leading to reduced carrying capacity between 0.2-0.5 ACU per ha, …

A Strategic Approach To Developing The Role Of Perennial Forages For Crop-Livestock Farmers, Rick Llewellyn, Michael Robertson, Richard C. Hayes, David Ferris, Clinton K. Revell, Katrien Descheemaeker

IGC Proceedings (1997-2023)

A substantial proportion of Australian animal production from grazing comes from regions and farms where cropping is the major enterprise. Developing new and improved grazing systems for mixed farms where crop production is the major driver of farm management decisions presents a unique research and development challenge. In this paper we describe a multi-disciplinary farming-systems research approach (‘EverCrop’) aimed at improving farm profitability, risk management and environmental impacts through the development and integration of new grazing options. It has been used to analyse and target new opportunities for farmers to benefit from perennial species across dry Mediterranean-type and temperate regions …

Improving Forage Nonstructural Carbohydrates Through Management And Breeding, Gilles Bélanger, Gaëtan F. Tremblay, Annick Bertrand, Yves Castonguay, Robert Berthiaume, Réal Michaud, Sophie Pelletier, Chantale Morin, Carole Lafrenière, Guy Allard

IGC Proceedings (1997-2023)

Nonstructural carbohydrates (NSC) are an important source of readily fermentable energy available to rumen microbes. Limited concentrations of readily available energy in forages combined with fast and intensive protein degradation contribute to poor N use efficiency by dairy cows and other ruminants. Increasing NSC in forages has been shown to improve intake, milk yield, and N use efficiency (Brito et al. 2009). We assessed several strategies to increase forage NSC accumulation, including PM-cutting, species selection and genetic improvement.
