The Tall Fescue Endophyte, Don Ball, Garry D. Lacefield, Carl S. Hoveland

Agriculture and Natural Resources Publications

Tall fescue (Festuca arundinacea Schreb.) is the most important cool-season grass in the United States, providing the primary ground cover on some 35 million acres. It is a versatile perennial used to provide pasture and hay for livestock, for various turf purposes, and for erosion control. Commonly referred to as simply "fescue," this widely adapted, persistent grass is seed propagated, tolerant of a wide range of management regimes, and it produces good forage yields. Laboratory nutritive analyses of fescue compare favorably to those of many other cool-season grasses.

Amelioration Effects Of Calcium Amendments On The Growth Of Phaseolus Vulgaris L. Under Sodium Stress, Salam Mahmoud Awada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two greenhouse experiments were conducted to determine the amelioration effect of Ca salts (CaS04 and CaC12) on the growth of snapbeans (Phaseolus vulgaris L.) under sodium stress and to determine the effect of ion speciation on the uptake of Ca, Na, S04, and Cl by snapbeans.

In Experiment 1, the seeds were grown in styrofoam pots, with a growing medium of sand and vermiculite at a volume ratio of 3:1. The treatment solutions were 0 (Hoagland's solution), 20, 40, 60, and 80 mmol_c/L NaCl or Na₂S0₄.

Statistical analysis (ANOVA) showed that NaCl treatments …

Potassium And Sodium Interrelations In Alfalfa Phenotypes Grown On Calcareous Soil, Suresh S. Dhumal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three greenhouse experiments were conducted with three phenotypes of alfalfa (Medicago sativa L.) obtained from a potassium (K)-deficient field and with their diallel crosses grown on low K soil. The first experiment was conducted to study the partitioning and broad-sense heritability of K and sodium (Na) between leaves and stems of the three phenotypes which were deficient in K and exhibited normal (N), marginal chlorotic (M), and white spot chlorotic (W) leaflets. The second experiment was conducted to study the partitioning of K and Na in leaves, stems, and roots as influenced by 32 alfalfa crosses obtained from diallel …

Hydrogen Uptake Genes And Nitrogen Fixation Efficiency Of Rhizobium Species In Symbiosis With Alfalfa, Chickpea And Pigeonpea, G. Mustafa Sajid

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The plasmids pDN211 and pDNll, isolated from the gene bank of the Rhizobium japonicum strain I-110, have been reported to complement two different Nif⁺ Hup^· (nitrogen fixation positive and hydrogen uptake negative) mutants. A 5.9-kb Hindiii DNA fragment of the cosmid pHU52, isolated from the gene bank of R. japonicum strain 122DES, has been reported to code for the two polypeptide subunits of uptake hydrogenase. To determine homology between the structural genes of uptake hydrogenase of the two strains, a Southern blot of the Hindiii restriction fragments of the plasmids pDN211 and pDN11 was hybridized to the 5.9-kb …

Bulletin No 4189 - Training And Care Of The Sheep-Dog, John Charlick, Department Of Agriculture, Western Australia

Bulletins 4000 -

A well trained sheep-dog is a considerable asset to a farmer — in a recent Queensland Department of Primary Industries study, participating graziers estimated the value of a good working dog to be up to $20,000 a year.

Despite their value, dogs can be maintained cheaply. The Queensland study quoted $130 a year as the most any grazier spent on an individual dog — for dry food, vaccine and treatments for internal and external parasites.

This Bulletin aims to show how to train a sheep-dog from a raw pup to a highly useful and well trained, mature dog. The methods …

The Role In Alfalfa In Soil Conservation, Glenn D. Johnson

Kentucky Alfalfa and Stored Forage Conference

Due to its many benefits, alfalfa has earned its reputation as "Queen of the Forages". Some of alfalfa's advantages are 1) very high nutritional value for all classes of livestock, 2) adaptability to a wide range of soils and growing conditions, 3) flexibility in being able to be grown alone or with grasses, 4) to be harvested for hay, silage or pasture, 5) strong seedling vigor and 6) high yields.

Alfalfa also should be rated "Queen of the Forages" as a crop for the soil. In addition to its many other benefits, alfalfa is an excellent choice for soil improvement …

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.

An Essay: Geoedaphics And Island Biogeography For Vascular Plants, A. R. Kruckerberg

Aliso: A Journal of Systematic and Floristic Botany

"Islands" of discontinuity in the distribution of plants are common in mainland (continental) regions. Such discontinuities should be amenable to testing the tenets of MacArthur and Wilson's island biogeography theory. Mainland gaps are often the result of discontinuities in various geological attributes-the geoedaphic syndrome of topography, lithology and soils. To discover ifgeoedaphically caused patterns of isolation are congruent with island biogeography theory, the effects of topographic discontinuity on plant distributions are examined first. Then a similar inspection is made of discontinuities in parent materials and soils. Parallels as well as differences are detected, indicating that island biogeography theory may be …

Simulation Of Shoot Vegetative Development And Growth Of Unstressed Winter Wheat, Gregory S. Mcmaster, Betty Klepper, R. B. Rickman, Wallace Wilhelm, W. O. Willis

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

Mechanistic crop simulation models can aid in directing research and improving farm management. Recent research on winter wheat (Triticum aestivum L.) canopy development was consolidated into a model of aboveground vegetative development and growth called SHOOTGRO 1.0. The model assumes that water, nutrients, and light do not limit development and growth. Initial conditions of cultivar type (dwarf, semidwarf, mid-tall, and tall), seeding rate, planting depth and date, and latitude are inputs. Daily temperature, expressed as growing degree-days, drives SHOOTGRO 1.0. Processes are simulated with a daily time step. Computer code is standard Fortran 77.

The morphological nomenclature used allows …

Phomopsis-Resistant Lupin Stubbles As Feed For Weaner Sheep, Colin Mcdonald, Keith Croker, Jeremy Allen

Journal of the Department of Agriculture, Western Australia, Series 4

The breeding of sweet, narrow-leafed lupins with increased resistance to Phomopsis leptostromiformis, the fungus that causes lupinosis in sheep, is a breakthrough for the summer nutrition of weaner sheep. The new resistant varieties, Gungurru for the medium (325 to 450 mm) rainfall areas and Yorrel for low rainfall areas (less than 325 mm), were released by the Department of Agriculture in 1988.

This article discusses progress in a four-year project which is examining liveweight and wool production of weaners grazing Gungurru stubbles.

Farm Management Memo - Advice To Help Farming Through The Rural Downturn, Department Of Agriculture, Western Australia

Farm Systems and Economics published reports

Historically, commodity prices cycle between a "boom and a bust" every few years. Farmers are often able to adjust their operations to reduce the impact of a downturn in commodity prices by:

• Increasing efficiency through reducing or maintaining input costs while maintaining or increasing production levels.

• Maximising returns through seeking price premiums on commodities (protein, noodle quality, finer wool, increased clean wool yield).

• Reducing overhead costs

• Seeking cheaper finance or refinancing costly loans

• Careful planning and management with a high degree of attention to detail.

• Seeking advice
