Growing Olives In Western Australia, Richard Taylor, John Burt

Bulletins 4000 -

There are about 9 million hectares of olives in the world, with the largest areas in Spain, Italy, Greece and Tunisia. Olives are grown between the latitudes of 30° and 45° from the equator. In Australia, the main producing areas are between latitudes 31° and 38°S. Production in Western Australia ranges from Chapman Valley, Northampton (29.5°S), to Albany (34.5°S). Olive production has increased markedly in Australia in the past ten years with a large increase in managed investment scheme olive groves. The Moore River region of the Shire of Gingin accounts for over 70 per cent of olive trees and …

Can Organic Agriculture Feed The World?, Catherine Badgley, Ivette Perfecto, Kenneth Cassman , Responder, Jim Hendrix , Responder

Department of Agronomy and Horticulture: Faculty Publications

During the past 30 years there has been a steady decrease in funding allocated to agricultural research in both developed and developing countries because of the widespread view that food insecurity is primarily caused by poverty and a lack of purchasing power rather than the inability to produce enough food. However, these views are being challenged by three global mega-trends: (1) a steady decrease in arable land area suitable for intensive food crop production as a result of farmland conversion to urban, industrial and recreational uses, (2) a steady reduction in the relative rate of yield gain for the major …

An Avidin-Based Assay For Histone Debiotinylase Activity In Human Cell Nuclei, Yap Ching Chew, Gautam Sarath, Janos Zempleni

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

The covalent binding of biotin to histones participates in heterochromatin formation, cell cycle progression and cellular response to DNA breaks. Biotinylation of histones appears to be a reversible process, but the identity of enzymes that remove biotin marks is largely unknown. Our long-term goal is to identify histone debiotinylases in human cells. Here we developed an avidin-based plate assay to quantify histone debiotinylase activities in nuclear extracts. This assay is an essential first step in purifying and identifying histone debiotinylases from human cells. Using this assay, we demonstrated that debiotinylation of histones depends on temperature and pH, consistent with enzyme …

Optimal Foraging In Eastern Fox Squirrel: Food Size Matters For A Generalist Forager, Robert Tatina

The Prairie Naturalist

Classical optimal foraging theory (OFT) predicts that an animal forages optimally when it chooses foods with the highest energy benefit or minimizes time searching for and handling food. r evaluated OFT by presenting eastern fox squirrel (Sciurus niger) multiple food items (i.e., sunflower seeds and • fruits) in various density combinations. When the choice was between foods of equal energy benefits but different costs, they chose forage items with greater costs, seemingly not foraging optimally. However, individuals showed a partial preference for food items which minimized search time, but not handling time. The eastern fox squirrel also was …

Effects Of Forage Management On Pasture Productivity And Phosphorus Content, M. M. Haan, J. R. Russell, J. L. Kovar, W. J. Powers, J. L. Benning

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

The objectives of the current study were to determine the amounts of above- and below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fall stockpile grazing (HS), rotational stocking to residual sward heights of 10 (10R) or 5 (5R) cm, and continuous stocking to maintain sward height at 5 cm (5C). Forage samples were hand-clipped within and outside grazing exclosures monthly from April through November …

Increased Abundance Of Arbuscular Mycorrhizal Fungi In Soil Coincides With The Reproductive Stages Of Maize, M. Susana Grigera, Rhae A. Drijber, Brian J. Wienhold

Department of Agronomy and Horticulture: Faculty Publications

Arbuscular mycorrhizal (AM) fungi are recognized for their positive effects on plant growth, playing an important role in plant P nutrition. We used C16:1cis11 and C18:1cis11 fatty acid methyl ester (FAME) biomarkers to monitor the dynamics of AM fungi during the reproductive stages of maize (Zea mays L.) grown at high yield in Nebraska, USA. Two fields with four different levels of P availability were sampled throughout the reproductive stages. Chambers, made of PVC enclosed mesh fabric to allow passage of roots and hyphae(+R) or hyphae alone (-R) and amended with either KH₂PO …

Sorghum: A Substitute For Maize In The West Africa Poultry Industry, Intsormil

INTSORMIL Impacts and Bulletins

With the declining relative prices of chicken compared with other meats, poultry consumption per capita in the USA has been increasing, while that of other meats has been stagnant or declining. Similar developments are occurring in West Africa.

There is interest in substituting sorghum for maize in poultry rations, in the U.S. and in West Africa, for both broiler and egg production. In contrast to maize, which is a thirsty plant and requires large amounts of water, sorghum offers farmers the ability to grow a crop where other crops do not produce well. In Niger, West Africa, locally produced sorghum …

The Banksia Production Manual, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There has long been a need for a Banksia Production Manual. The benefit of such a manual is the ability to bring together the material written and published in a range of other publications and reports.

As far as possible the latest information has been reviewed and incorporated. Some of these areas have a limited set of information available and are accordingly brief. We have tried to incorporate grower information where possible to ensure that what is discussed has a practical grounding. While regulations and information was correct at the time of publication (April 2007), it is recommended that people …

Sorghum: Nutritional Feed For U.S. And African Poultry, Intsormil

INTSORMIL Impacts and Bulletins

Grain sorghum, an important dryland crop in the Central Great Plains of the United States, is adapted to growing in areas where low and erratic rainfall and high temperatures limit production of other crops such as maize and soybeans. The United States is the largest producer of grain sorghum with 6 million acres devoted to production of this crop in 2005. Kansas produces more grain sorghum, commonly known as milo, than any other U.S. state. Kansas growers value sorghum because it performs well in many types of soils and weather. More than 80% of the sorghum produced in Kansas is …

Invasion By Aegilops Triuncialis (Barb Goatgrass) Slows Carbon And Nutrient Cycling In A Serpentine Grassland, Rebecca E. Drenovsky, Katharine M. Batton

Biology

Invasive plant species alter plant community composition and ecosystem function. In the United States, California native grasslands have been displaced almost completely by invasive annual grasses, with serpentine grasslands being one of the few remaining refugia for California grasslands. This study examined how the invasive annual grass, Aegilops triuncialis, has altered decomposition processes in a serpentine annual grassland. Our objectives were to (1) assess howA. triuncialis alters primary productivity and litter tissue chemistry, (2) determine whether A. triuncialis litter is more recalcitrant to decomposition than native litter, and (3) evaluate whether differences in the soil microbial community in A. triuncialis-invaded …

Gold’N Gro® 9-0-1 + 7% Zn Improves Corn Growth In Zn-Deficient Soil: A Preliminary Study, Julie K. Chard, Bruce Bugbee

Nutrients

Zinc deficiency can limit growth, especially on soils with low organic matter and high pH. Chelated Zn fertilizers maximize Zn bioavailability. We sought to determine the effectiveness of soil-applied GOLD’n GRO 9-0-1 + 7% Zn, a chelated Zn source, to reverse or prevent Zn deficiency. GOLD’n GRO was applied at 0 to 30 quarts per acre in a high pH soil. Controls included columns treated with ammonium-nitrogen at the same level as the highest GOLD’n GRO treatment. Plants treated with GOLD’n GRO had twice the dry mass, were greener, and had increased zinc levels in the plant tissue compared to …
