Bulletin 4446 - Ord Land And Water Management Plan 2000, Agriculture Western Australia, Community Of Kununurra

Bulletins 4000 -

The wise use of the land and water of the Ord has become an imperative driven by increasing awareness of the impacts of current uses on ground water and the on the quality of the Ord River itself.

We have been lucky as a community that these resources are still in reasonable order and that we have the time to address the resource management challenges associated with our use of them. There is a wide range of land and water management issues to be addressed and all those involved have responsibilities to address some of those issues.

Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw

Theses : Honours

Increasing soil salinity has become a major problem worldwide. It has led to a reduction in the amount of arable land, has put at risk the supply of freshwater and threatens the existence of many natural habitats. The major increase in salinity has been attributed to human activities such as clearing of natural vegetation and large-scale irrigation programmes. The alleviation of this problem has focussed on changed management strategies. the most significant of which is the re-establishment of deep rooted plants in sail affected areas. This, however, is difficult because of the variation in salt tolerance of such plants and …

Evaluation Of Forty-Two Corn (Zea Mays L.) Genotypes And Their Tolerance To Drought In Chiquimula, Servin Ardany Flores Galdámez

Theses and Dissertations

The Corral de Piedra community is located in Chiquimula, Guatemala. The main agricultural activities are corn and bean production, small-scale gardens, and small animal production, such as poultry and pigs. The crop areas are predominantly located on lands with slopes between 12 and 55%, presenting low fertility conditions and poor moisture retention capabilities. In addition, local crop varieties have low productivity potentials and the winter season is characterized by poorly distributed and erratic periods of rain. The Benson Institute introduced a technology transfer model to increase and diversify agricultural production, while preserving current natural resources. An integral part of this …

Feeding Fitness And Quality Of Domesticated And Feral Predators: Effects Of Long-Term Rearing On Artificial Diet, Allen Carson Cohen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Predatory geocorids, Geocoris punctipes Say (Geocoridae: Hemiptera), that had been reared (domesticated) for over 6 years (60 continuous generations) on an artificial diet were compared with feral (F1) counterparts to determine possible domestication-associated losses in predatory capabilities. Using adult female predators provided with either tobacco budworm larvae, Heliothis uirescens F., or pea aphids, Acyrthosiphon pisum Harris, as prey, I measured predator weights, handling time with a single prey, amount extracted, consumption rate, and feeding (gut) capacity. Domesticated females were significantly smaller than ferals, weighing 4.53 mg versus 5.09 mg, respectively. Domestication did not significantly influence handling times, which averaged 131 …

Kernel Morphology Variation In A Population Derived From A Soft By Hard Wheat Cross And Associations With End-Use Quality Traits, Christine J. Bergman, Daisy G. Gualberto, Kimberly A. Garland-Campbell, Mark E. Sorrells, Patrick L. Finney

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Physical attributes, including kernel morphology, are used to grade wheat, and indicate wheat milling and baking quality (MBQ). Using a recombinant inbred population derived from a soft by hard wheat cross, this study quantified kernel traits' sources of variation, studied their heritability, and relationships between morphological and MBQ traits. Transgressive segregation occurred for all traits. Thousand-kernel weight (TKW) and kernel texture (NIR-T) were primarily influenced by genotype and test weight (TW) mainly by year. NIR-T had the highest heritability. Low genetic correlation (GCOR) between kernel length (LEN) and width WID) suggest independent inheritance. NIR-T and LEN, or WID, showed low …

Department of Agronomy and Horticulture: Faculty Publications

Weeds interfere with establishment of native grasses and legumes. A study was conducted to determine the influence of imazapic¹ [(±)- 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]- 5-methyl-3-pyridinecarboxylic acid] and imazethapyr [2-[4,5-dihydro- 4-methyl -4 - (1- methylethyl) -5 -oxo-1H- imidazol -2 - yl]5- ethyl -3- pyridinecarboxylic acid] on weed control and establishment of ‘Pawnee’ big bluestem (Andropogon gerardii Vitman var. gerardii Vitman) and Illinois bundleflower [Desmanthus illinoensis (Michx.) MacMill.] planted in three binary mixtures of 220:110, 165:165, and 110:220 pure live seed (PLS) m^-2. Mixtures were seeded at cropland sites near Clay Center, Mead, and Lincoln, NE. Imazapic and imazeth- apyr …

Crop Quality And Utilization: A Twelve-Hour In Vitro Procedure For Sorghum Grain Feed Quality Assessment, Jeffrey F. Pedersen, Todd Milton, R. A. Mass

Department of Agronomy and Horticulture: Faculty Publications

Improvedmethods for assessing cereal crop feed value are a prerequisite for the genetic improvement of sorghum [Sorghum bicolor (L.) Moench] feed value. Rate of starch digestion is now commonly believed to be the limiting factor in sorghum utilization by cattle (Bos taurus). However, techniques to assess this trait are not useful to sorghum breeders because of high labor inputs, lab error associated with starch measurement, and need for high numbers of replications. The objective of this study was to develop a simple technique capable of identifying differences in digestion between sorghum and corn (Zea mays L.) …

Ethylene Production, Cluster Root Formation, And Localization Of Iron(Iii) Reducing Capacity In Fe Deficient Squash Roots, Brian M. Waters, Dale G. Blevins

Department of Agronomy and Horticulture: Faculty Publications

Dicots and non-graminaceous monocots have the ability to increase root iron(III) reducing capacity in response to iron (Fe) deficiency stress. In squash (Cucurbita pepo L.) seedlings, Fe(III) reducing capacity was quantified during early vegetative growth. When plants were grown in Fe-free solution, the Fe(III) reducing capacity was greatly elevated, reached peak activity on day 4, then declined through day 6. Root ethylene production exhibited a temporal pattern that closely matched that of Fe(III) reducing capacity through day 6. On the 7th day of Fe deficiency, cluster root morphology developed, which coincided with a sharp increase in the root Fe(III) …

Agronomical Behavior Of Two Kinds Of Swiss Chard (Beta Vulgaris Var. Cicla L.) Fertilized With Earthworm Humus In An Underground Greenhouse In Viacha, La Paz, Walter Von Boeck

Theses and Dissertations

The objective of the following work was to evaluate the agronomical behavior of two kinds of Swiss chard fertilized with earthworm humus, and at the same time to know the yield and the costs of production. This work was done in the community of Letanias, located 32 km. from the Department of La Paz and at an altitude of 3860 meters above sea level. Two kinds of Swiss chard were used in this work, Fordhook Giant and Petoseed C003. The three doses of earthworm humus, used as fertilizers, were a2, a3, and a4. The quantity of fertilizer used was 1314, …

Post–Green Revolution Trends In Yield Potential Of Temperate Maize In The North-Central United States, D. N. Duvick, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

This paper addresses the question of whether there has been an increase in yield potential of maize (Zea mays L.) hybrids released in the north-central United States since the advent of the “Green Revolution” that began in the late 1960s. Because there are few published data about hybrid growth rates and yield-determining plant traits when grown at yield potential levels, we attempt to address this issue indirectly by evaluation of maize breeding efforts, changes in plant traits of commercial hybrids, and by comparison of statewide average yield trends and yield trends in sanctioned yield contests. On the basis of …

Dnak And The Heat Stress Response Of Pseudomonas Syringae Pv. Glycinea, Lisa M. W. Keith, James E. Partridge, Carol L. Bender

Department of Plant Pathology: Faculty Publications

The dnaK gene from Pseudomonas syringae pv. glycinea PG4180 was cloned and sequenced. The dnaK coding region was 1,917 bp and contained a putative O³² heat shock promoter 86 bp upstream of the translational start site. grpE, another heat shock gene, was found immediately upstream of the putative dnaK promoter. The predicted amino acid sequence of dnaK showed relatedness to the ATPase and substrate binding domains commonly found in heat shock proteins, as well as the highly conserved signature sequence motifs belonging to the Hsp70 protein family. Furthermore, the PG4180 dnaK gene complemented an Escherichia coli dnaK mutant …

Bulletin 4369 - Ord River Irrigation Area - Kununurra Western Australia, Agriculture Western Australia

Bulletins 4000 -

The Ord River Irrigation Area (ORIA) in the Kimberley Province of Western Australia is the product of a bold and imaginative plan to develop part of the nation's tropical north for intensive agriculture by harnessing the waters of the Ord River. The principal features of the scheme are:

* A major storage reservoir formed by a dam constructed where the Ord River enters the Carr-Boyd Ranges, 160 kilometres south-east of Wyndham.

* A diversion dam, 50 kilometres further downstream, to raise the river level and divert water to be released from the major storage reservoir onto the irrigable lands.

* …

Morphogenesis Is Coordinated With Nuclear Division In Germinating Aspergillus Nidulans Conidiospores, Steven D. Harris

Department of Plant Pathology: Faculty Publications

Germinating Aspergillus nidulans conidiospores switch to polarized apical growth following an initial period of isotropic expansion. At the same time, they re-enter the nuclear division cycle. The relationship between spore polarization and nuclear division was investigated by testing the effect of cell cycle inhibitors and temperature-sensitive cell cycle mutations on spore morphogenesis. On rich media, it was found that spore polarization is delayed if completion of the first mitosis is blocked. The observed delay may be dependent upon the activity of the mitosis-promoting NIMA kinase. An additional mechanism appears to prevent polarization as the spore progresses through its first S …
