Potential Of Indigenous Desert Grasses For Forage Production In A Water-Scarce Region, A. E. Osman
Potential Of Indigenous Desert Grasses For Forage Production In A Water-Scarce Region, A. E. Osman
IGC Proceedings (1997-2023)
Indigenous perennial grasses are widely distributed in the Arabian Peninsula. Their survival under limited rainfall and grazing suggests a potential role as grassland species and for rehabilitation of degraded rangelands. Forage productivity and water-use efficiency (WUE) was determined over 2 years for four indigenous grasses: buffel grass (Cenchrus ciliaris L.), dakhna (Coelachyrum piercei Benth.), da’ay (Lasiurus scindicus Henr.) and tuman (Panicum turgidum Forssk.) together with one exotic species, rhodes grass (Chloris gayana Kunth) in the central region of the United Arab Emirates. Three irrigation treatments were used: R1 (1858–6758 m3 ha-1 year-1 …
Balancing Water Use Efficiency And Milk Production In The Sub-Tropics, Mark N. Callow, S. K. Kenman
Balancing Water Use Efficiency And Milk Production In The Sub-Tropics, Mark N. Callow, S. K. Kenman
IGC Proceedings (1997-2023)
Queensland dairy farmers have had to confront in the last 5 years deregulation of the milk pricing system, resulting in a 25% reduction in farm gate price for milk in the year 2000, and drought. Many storage dams are significantly below capacity and regulatory authorities have imposed restrictions on irrigation water allocations. Major changes in farm business strategies were needed to overcome the shortfall in milk income. Production systems had to change to deliver more milk more efficiently and become more profitable. A farmlet study was developed in the sub-tropical dairy region of Queensland to evaluate 5 very different farm …
Improvement Of Native Perennial Forage Plants For Sustainability Of Mediterranean Farming Systems, F. Lelièvre, Florence Volaire
Improvement Of Native Perennial Forage Plants For Sustainability Of Mediterranean Farming Systems, F. Lelièvre, Florence Volaire
IGC Proceedings (1997-2023)
The amount of water available to agriculture in the Mediterranean is declining because of increasing population pressure and greater incidence of drought. Therefore, the efficiency of the use of water for agricultural production must be maximized and, in this context, perennial forage species have a number of advantages in comparison to the predominantly-used annuals. They can utilize water throughout the whole year besides being able to halt rangeland degradation, restore soil fertility and enhance forage production, thereby contributing to greater sustainability of rain-fed agricultural systems in the southern European Union and North Africa. Despite these advantages, the small size of …
