Toward Optimizing Fruit Production In Utah Soils: Apple Salt Tolerance Screening And Tart Cherry Fertility Management, Kaitlin Dabbs

All Graduate Theses and Dissertations, Fall 2023 to Present

Fruit production in Utah can be challenging due to local climate and soil conditions. Tart cherries and apples are major fruit crops in Utah, and improvements to these cropping systems would be beneficial for farmers and local consumers. Two experiments were conducted to evaluate desired improvements for these crops. The first study looked for salt tolerance in ten new apple rootstocks. Salty soils can be found throughout the state limiting the land suitable for apple production. When grown in salty soils apple trees often have reduced growth and production potential. A specialized drip irrigation system was constructed in a greenhouse …

Pumping Groundwater For Salinity Control In Wa, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

DPIRD recommends that groundwater pumping is used as part of an integrated water and salinity management program.

Groundwater pumping can lower local water tables, recover land for production and reduce the spread of local salinity or to protect high value assets at risk, such as townsites, roads or railway lines. Pump water can be discharged to safe disposal points or used on farm for desalination.

Roaded Catchments In Wa, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Roaded catchments are earthwork structures designed to increase the amount of run-off from the catchment above a receiving farm dam.

Roaded catchments are lined with clay and compacted to make a smooth surface that reduces infiltration and increases run-off. Roaded catchments should discharge into a silt trap and then into a dam (excavated earth tank). This combined structure should be fenced to exclude livestock.

The Department of Primary Industries and Regional Development recommends that roaded catchments are part of an integrated water and salinity management program.

Intraspecific Variation For Salt Tolerance In White Clover, M E. Rodgers, C L. Noble, M E. Nicolas, G M. Halloran

IGC Proceedings (1977-2023)

Variation in the salt tolerance of 10 commercial cultivars of white clover (Trifolium repens L.) was evaluated in greenhouse and field· experiments over a range of NaCl concentrations. Cultivars differed significantly in terms of yield, shoot ion concentrations and parameters of growth such as leaf expansion and petiole elongation rates but not in the root concentrations of Cl or Na. The ability to control the entry and distribution of Cl and Na into the shoot (demonstrated by tolerant cultivars Haifa and irrigation compared with sensitive cultivars Ladino and Tamar) was related to the salt tolerance rankings observed in both …

Open Groundwater Drains In Wa, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Open groundwater drains are excavated channels with sloping floors and sides and open levees, designed to intercept and drain surface (usually fresh) and groundwater (usually saline in WA) from agricultural land. These drains are most effective where the channel is dug below a water table in soils that allow good lateral drainage.

DPIRD recommends leveed groundwater drains in most cases. These should form part of a whole farm and whole catchment integrated water and salinity management program. Information on this page is a guide only. It is highly recommended that landholders considering the construction of open drains seek expert advice …

Salinity Responses In Some Forage Legume Species, M E. Rogers

IGC Proceedings (1977-2023)

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

IGC Proceedings (1977-2023)

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

IGC Proceedings (1977-2023)

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 (1977-2023)

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 (1977-2023)

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 …

The Effects Of Saline Soil On Microbiome And The Isolation Of Root-Associated Microbes To Relieve Salinity Stress, Duncan Jakubowski

Electronic Theses and Dissertations

Increasing levels of salinity in once-viable lands for crop production is a serious and growing problem in the Northern Great Plains. The objectives of this study were to determine the effects of saline soil on the microbial composition of plant roots and bulk soil, to measure metabolic changes in plant roots from saline soil, to determine the viability of root-associated microbes as inoculants to increase stress tolerance in plants, as well as determine the impact of saline soil on nitrogen cycling genes linked to greenhouse gas production. This study hypothesizes that high soil salinity levels have a significant impact on …

Salt-Tolerant Forages For Irrigated Saline Land In Central Iraq, Iman S. Salman, Edward G. Barrett-Lennard, Kareem Kadhim, Shoaib Ismail, Hayley C. Norman

IGC Proceedings (1977-2023)

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 …

Increasing Pasture Production On Drained Saltland, Penny Roberts Craig, Freya Hawker, Amanda L. Bonython, Andrew Craig

IGC Proceedings (1977-2023)

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

IGC Proceedings (1977-2023)

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 …

The Growth Response Of Tropical And Sub-Tropical Forage Species To Increasing Salinity, Hayley E. Giles, Christopher J. Lambrides, Scott A. Dalzell, David C. Macfarlane, H. Max Shelton

IGC Proceedings (1977-2023)

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 …
