Salinity Responses In Some Forage Legume Species, M E. Rogers
Salinity Responses In Some Forage Legume Species, M E. Rogers
IGC Proceedings (1997-2023)
The salt tolerances of more than 70 lines and species of forage legumes were evaluated in a series of greenhouse experiments, with the aim of identifying plant material that is more salt tolerant than some of the more traditionally-grown, temperate, forage legume species. Several species or lines showed potential as salt tolerant germplasm including sweet clover (Melilotus albus), berseem clover (T. alexandrinum) cvv. Mescani and Wardan, woolly clover (T. tomentosum), birdsfoot treefoil (L. Corniculatus), slender birdsfoot treefoil (Lotus tenuis) and Trifolium squamosum. However, further selection and field evaluation is required in order to …
Early Ontogenetic Responses Of Six Commercial Chloris Gayana Cultivars To Salinity, E Taleisnik, H Perez, G Peyrano, C Arias
Early Ontogenetic Responses Of Six Commercial Chloris Gayana Cultivars To Salinity, E Taleisnik, H Perez, G Peyrano, C Arias
IGC Proceedings (1997-2023)
Some physiological aspects relevant to pasture establishment under saline conditions were evaluated in six cultivars of Chloris gayana . Two tetraploid cultivars: Boma and Callide, and four diploid ones: Bell, Katambora, Pioneer and a local accession of Pioneer, were analyzed. The effect of salinity on seedling emergence, the number of stolons per plant and frost tolerance were evaluated in the field, while effects on germination, early vegetative growth, regrowth after clipping, ion accumulation and stolon rooting were assessed in the greenhouse. Salinity had a negative effect on seedling emergence. Saline solutions delayed or altogether inhibited germination, but seeds retained viability …
Are New Farming Systems Based On Perennial Pastures In South West Australia More Profitable?, Paul Sanford, J. Young
Are New Farming Systems Based On Perennial Pastures In South West Australia More Profitable?, Paul Sanford, J. Young
IGC Proceedings (1997-2023)
Traditional farming systems in south west Australia based on annual plants have been shown to use insufficient water leading to excess leakage below the root zone, groundwater rise and eventually salinisation of the landscape. Introduction of deep-rooted summer active perennial plants can significantly increase water-use thus reducing the risk of salinisation. However the adoption of perennials by farmers is also dependent on their effect on economic factors. This paper reports an analysis of the impact of perennials on whole farm profit.

Regeneration Of Old Ungrazed Old Man Saltbush (Atriplex Nummularia) Stands In South-West Australia, S. J. Bennett, S. G. Low, D. Collins, V. Crouch
IGC Proceedings (1997-2023)
Many old man saltbush (Atriplex nummularia) stands were sown in the grainbelt of Western Australia for soil regeneration and salinity management up to 25 years ago, but have not been effectively grazed subsequently, such that the main feed available for sheep is above grazing height. The aim of the study was therefore to see if it was possible to return the old man saltbush stands to a productive grazing stand.
Two sites were chosen that had been sown up to 25 years previously in Goomalling and Corrigin, in the south-west of Western Australia. The sites were split into …

High Salinity Effects On The Components Of Relative Growth Rate In Rhodes Grass, E. Taleisnik, L. García Seffino, A. Córdoba, K. Grunberg, C. Arias, M. De Luca
IGC Proceedings (1997-2023)
Rhodes grass (Chloris gayana Kunth), is widely cultivated in the semiarid tropics and favored for its salt tolerance. Nevertheless, productivity decreases significantly under saline conditions, especially in tetraploid cultivars. The purpose of this work was to explore, in tetraploid cultivar Boma, the physiological causes for the observed salt-associated growth reduction. The effects of high salinity (200 mM NaCl) on the components of relative growth rate were analyzed in greenhouse experiments. An early reduction in leaf area expansion was observed, which later resulted in decreased dry matter accumulation. Plant leafiness was reduced by effects both on dry matter allocation to …

IGC Proceedings (1997-2023)
Salinity is a major problem in the irrigated zones of central and southern Iraq. We investigated biomass production from five salt-tolerant forage species, represented by 15 introduced accessions and 3 local accessions, during two successive summer growing seasons. Species included pearl millet (Pennisetum glaucum), sorghum (Sorghum bicolour), guar (Cluster bean; Cyamopsis tetragonoloba), cowpea (Vigna unguiculata) and sesbania (Sesbania aculeata and S. sesban). The research site was located in the Al-Dujaila irrigation project area in Wasit. The soil had a silty clay texture with moderate salinity (ECe 10-20 dS/m). The site was …

IGC Proceedings (1997-2023)
The Upper South East of South Australia has been identified as being at risk of extensive soil degradation, with large areas already affected by dryland salinity and waterlogging. To mitigate this, an extensive network of drains has been installed. In 2009, 19 soil surveys were conducted on land adjacent to a number of deep drains (> 1.0 m) in order to determine soil salinity and pH. The surveys indicated low levels of topsoil salinity (0-10 cm) in the southern part of the region, while 66% of soil sampling sites in the northern zone had salinity levels (ECe) below 4 dS/m. …
Cellular Causes For Leaf Elongation Reductions Under Salinity In Panicum Coloratum, Leandro Cáceres, Edith Taleisnik
Cellular Causes For Leaf Elongation Reductions Under Salinity In Panicum Coloratum, Leandro Cáceres, Edith Taleisnik
IGC Proceedings (1997-2023)
Soil salinity is a growing constraint to crop and forage production worldwide and has driven the quest for salt-tolerant germplasm. Perennial forage grasses are regarded as choice alternative for the productive use of saline areas as well as for mitigating salinity in these areas (Ridley and Pannell 2005). Panicum coloratum L. is a C4 perennial grass native to tropical Africa, adapted to a wide range of rainfall conditions which makes it attractive as a forage for semiarid areas (Jones 1985). In forage grasses, yield is directly related to leaf area expansion and duration and the purpose of this work was …

IGC Proceedings (1997-2023)
There is currently a growing coal seam gas (CSG) industry in Queensland, Australia. The industry requires beneficial-use strategies to consume the significant volumes of water released during CSG extraction. Irrigation of tropical and sub-tropical forage species for beef production is one option, however coal seam (CS) water is of varying quality due to moderate to high salinity and alkalinity. The application of chemically amended CS water over time could potentially increase soil salinity, which is known to reduce plant biomass production. While there were studies of salinity tolerance of many tropical and sub-tropical forage species 30 years ago, there is …

IGC Proceedings (1997-2023)
Successful seedling establishment depends on the frequen-cy and the amount of precipitation as well as on the ability of the seed species to germinate and grow while soil mois-ture and osmotic potentials decrease. Germination and seedling characteristics are the most valuable criteria for selecting salt tolerance in plants. Salinity stress can reduce seed germination through osmotic effects (Jamil et al. 2006). Agropyron is a perennial grass genus with 19 dif-ferent species reported. This genus has wide adaptation and can be grown in different climates.
The objective of this study was to evaluate the impact of salinity stress on the germination …

Exploitation Of Wastelands For Fodder Production And Agroforestry, Gurbachan Singh
IGC Proceedings (1997-2023)
Natural resources degradation for agricultural production and environmental protection has been a matter of concern for future food, nutrition, environment and livelihood security. As per current estimates, 120.7 million hectare (mha) is under degraded or wastelands. These lands provide ample opportunity for growing fodder trees and grasses to bridge the gap between demand and supply of green and dry fodder.Several species of fodder trees and grasses have been identified and their agro-techniques standardized for raising in different categories of wastelands such as affected by soil and wind erosion, salinity, acidity and mining etc. A brief account of such plants is …
