Revegetation Guide To The Central Wheatbelt, E C. Lefroy, R J. Hobbs, L J. Atkins, Department Of Agriculture And Food, Western Australia, Csiro, Division Of Wildlife And Ecology
Bulletins 4000 -
The rapid development of the central wheatbelt for agriculture over the past century has produced a productive farming landscape, but one which is increasingly subject to degradation. Erosion, salinization, declining soil structure, waterlogging and acidification are all symptoms of this degradation and causes of lost agricultural production. In addition, most of the native vegetation and many of the native animals have disappeared, and the natural heritage of the area resides in small scattered patches that together make up only seven per cent of the wheatbelt region.
Many farmers now recognize that replanting trees and shrubs is an effective means of …

Review Of The Wild Oat Inflorescence And Seed: Anatomy, Development And Morphology, M. V. S. Raju, David M. Sutherland
Biology Faculty Publications
This slim volume describes a detailed study of the reproductive parts of Avena fatua, the wild oat plant-a common weed in the northern plains and the probable ancestor of the cultivated oat. The book integrates the author's own work with information from available literature and includes lengthy technical descriptions of the structure and the growth of the inflorescence, the floret, the ovule, the pollen grain, the embryo, the seed, and the young seedling. Throughout the work, the author relates the wild oat's structure and development to other grasses, other monocotyledons, and other seed plants, offering evolutionary interpretations of many of …

Timing Of Nitrogen Fertilizer Application For Cereals, M G. Mason
Timing Of Nitrogen Fertilizer Application For Cereals, M G. Mason
Division of Plant Research : Technical Report Series
Results are presented for 206 trials carried out between 1959 and 1990, investigating the effect of time of application of nitrogen fertilizers on cereal grain yields. This set of data is the basis of recommendations made for timing of nitrogen fertilizer application for cereals in Western Australia. Attention is drawn to the variability of results obtained in different seasons and situations and the time of leaching rains.

Hybrid Variation For Yield, Crude Protein, And Feed Value Of Corn, Z. Hu, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap
Hybrid Variation For Yield, Crude Protein, And Feed Value Of Corn, Z. Hu, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap
Agronomy Notes
The value of corn as a feed grain depends on the yield per acre, the protein content of the grain, and for some livestock, the lysine level of the protein. Most farmers are aware of yield differences among hybrid corn varieties but may not realize that protein content can also vary significantly. Grain protein level should be accounted for to determine how much protein supplementation will be needed to balance an appropriate animal diet. However, since corn protein is deficient in the amino acid lysine, which is essential for non-ruminant animals, lysine content as well as crude protein content should …

Grass Control In Corn With Accent And Beacon, W. W. Witt, Charles H. Slack, James R. Martin, Jonathan D. Green, M. A. Thompson
Agronomy Notes
The traditional method for grass control in corn is based on using herbicides applied to soil and incorporated before planting or to the soil surface after planting. This approach has been successful in controlling crabgrass, fall panicum and foxtails, but johnsongrass and shattercane control was sometimes inadequate.

Nitrogen Fertilizer Use By A High Yielding No-Till Corn Crop, Kenneth L. Wells, H. B. Rice, William O. Thom
Nitrogen Fertilizer Use By A High Yielding No-Till Corn Crop, Kenneth L. Wells, H. B. Rice, William O. Thom
Agronomy Notes
At the present time there is public concern about the effect which nitrogen (N) fertilizer use by farmers has on groundwater quality. This has resulted in research efforts to describe what happens to nitrogen fertilizer after it is applied to a crop. We have conducted a study for the past 3 years which enables us to make a reasonable estimate of how much fertilizer N is taken up by a high yielding corn crop. And, depending on whether the corn is harvested for silage or grain, we have estimated how much of the fertilizer N is removed from the field. …

Curling Burley Tobacco From An Automated Harvesting System, Linus R. Walton, Larry G. Wells, James H. Casada
Curling Burley Tobacco From An Automated Harvesting System, Linus R. Walton, Larry G. Wells, James H. Casada
Biosystems and Agricultural Engineering Faculty Publications
If burley tobacco can be successfully cured at high density under waterproof covers in the field, a producer can expand production without the necessity of building new curing barns and can thereby more easily justify investment in the automated burley tobacco harvesting system (Wells et al., 1990a, b). Curing under waterproof covers in the field and curing on frames in the barn were evaluated over three curing seasons using two varieties (KY 14 and TN 86), two plant densities (32 and 43 plants/m2, 3 and 4 plants/ft2), position of tobacco on the frame (four levels ranging …

Basic Alfalfa Germplasms Differ In Nutritive Content Of Forage, Andrew W. Lenssen, E. L. Sorensen, G. L. Posler, L. H. Harbers
Andrew W. Lenssen
Little information is available regarding comparative forage quality of alfalfa (Medicago sativa L.) leaves and stems of the nine germplasms from which most North American cultivars have been developed. In a greenhouse trial, forage quality of leaves and stems of the nine germplasms was compared when grown in a common environment and harvested at the same phenological stage. Germplasm sources (and representative cultivar) tested were: Indian (Sirsa #9), African (African), Peruvian (Hairy Peruvian), Flemish (DuPuits), Turkistan (Lahontan), Chilean (Kansas Common), M. varia Martin (Grimm), Ladak (Ladak), M. falcata L. (Anik). Leaves of germplasm sources differed for concentrations of neutral detergent …

1990 Kentucky Red Clover Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson
Agronomy Notes
Red clover is a high quality, shortlived perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, and soil improvement. This species is adapted to a wide range of climatic and soil conditions and therefore is very versatile as a forage crop. Stands are generally productive for two or three years with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is the dominant legume in Kentucky because it is high in seedling vigor, quality, yield, and animal acceptance.

Origin And Evolution Of Defective Interfering Rnas Of Tomato Bushy Stunt Virus, David A. Knorr, Thomas Jack Morris
Origin And Evolution Of Defective Interfering Rnas Of Tomato Bushy Stunt Virus, David A. Knorr, Thomas Jack Morris
School of Biological Sciences: Faculty Publications
Viruses with defective genomes have been identified in association with virtually every major family of viruses and have been widely utilized as tools for investigating virus functions in animal cell culture systems (Perrault, 1981). It is generally thought that defective interfering viruses (DIs) arise through deletion, rearrangement, or recombination of a competent viral genome. DIs tack the ability for independent existence relying on their parental helper viruses to supply factors required for replication, maturation, and/or encapsidation (Huang and Baltimore, 1977). The interference attributed to DIs is thought to result from competition with the helper virus for factors required in trans …

Tree Crops For Profit And Land Improvement, John Bartle
Tree Crops For Profit And Land Improvement, John Bartle
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.

Whole-Farm Planning : Success At Wilgi Creek, Kevin Shanhun
Journal of the Department of Agriculture, Western Australia, Series 4
Ian and Bev Lynch own Wilgi Creek, a 376 ha mixed farming property at West Mount Barker in the 700 mm rainfall zone. In 1983, they started a whole-farm plan to overcome the problems of declining production caused by waterlogging (their biggest problem), salinity and deterioration of the remnant native vegetation. Today, their property is an example of a successful, wholefarm land conservation plan based on agroforestry, timber production, water harvesting and improved pastures.
