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 …

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.

Miscellaneous Publication 17/91 - Mudas - Model Of An Uncertain Dryland Agricultural System: A Description, R. S. Kingwell, A. D. Bathgate

Farm Systems and Economics research reports

In the early 1980s, the Department of Agriculture developed a mixed integer whole-farm mathematical programming model of the dryland farming system in the eastern wheatbelt of Western Australia (Morrison et al. 1986). The model named MIDAS (Model of an Integrated Dryland Agricultural System) was constructed, tested and scrutinised by a multi-disciplinary team of researchers, advisers, farm management consultants and farmers (Kingwell 1987a). The model described in some detail the biology and finances of the dryland farming system in an average season and calculated profit-maximising farm plans.

MIDAS remains an often used tool in research and extension, being applied to many …

Osmophores, Floral Features, And Systematics Of Stanhopea (Orchidaceae), Kenneth J. Curry, Lorraine M. Mcdowell, Walter S. Judd, William Louis Stern

Faculty Publications

The floral fragrance glands (osmophores) of 18 species of Stanhopea and Sievekingia were examined through a series of developmental studies at light and electron microscope levels including late bud stages through postanthesis. Various characters were identified to be of potential systematic value and were recorded for each species. These characters included: texture of the osmophore surface, number of distinct cell layers comprising the osmophore, nature of lipid inclusions in osmophore cells, and presence or absence of plastoglobuli in osmophore amyloplasts. These characters were combined with traditional features of floral lip morphology for cladistic analysis. Sievekingia was the postulated outgroup. Stanhopea …

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 …

Study Of Ferredoxin And Flavodoxin From Tobacco Leaves And Roots Under Normal And Iron-Stressed Conditions, I-Jen Huang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I purified tobacco leaf ferredoxin from normal and iron-stressed leaves. The oxidized form of ferredoxin from normal leaves had absorption maxima at 268, 327, and 422 nm and a shoulder at 463 nm. The oxidized form of ferredoxin from iron-stressed leaves had absorption maxima at 268 and 329 nm but no absorption maxima in the 400-nm range. Higher ferredoxin content was found with higher chlorophyll content in leaves of the same age.

A protein in tobacco root extract was isolated and found to serve as an electron carrier for ferredoxin-requiring nitrite reduction. This protein had a molecular weight and antigenic …

Describing The Flora Of The United States: Botanies At Libraries In Syracuse, Dudley J. Raynal

The Courier

The first written descriptions of the flora of North America were those of sixteenth-century Europeans who marvelled at the botanical treasures brought to them by explorers of the New World. The earliest account of American natural history was that of the English botanical explorer Thomas Hariot who wrote his Briefe and True Re, port of the New Found Land of Virginia in 1590 after returning from an expedition arranged by Sir Walter Raleigh. Hariot carried to En, gland tubers, fruits, and seeds of plants previously unknown in Europe. Perhaps thirty different plant species had been introduced into Europe from the …

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 …

Grazing Alfalfa, Harlan E. White

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has tremendous potential as a pasture plant. The characteristics such as high yields, high quality, persistence, and drought tolerance that make it so valuable for hay and silage production also make it extremely useful for grazing. Properly managed so it has adequate recovery periods after being grazed, it can provide grazing over a six-month grazing season.

Hay Testing And Marketing Update, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

The hay testing program of the Kentucky Department of Agriculture continues to be actively involved across the state. Presently, there are stationary NIR labs in Frankfort, Glasgow, and Paducah. These labs operate somewhat differently from traditional forage testing labs because, for the price of analyzing the forage sample ($10), they will actually come to the farm and sample your hay! To get your forage analyzed, call the Department of Agriculture in Frankfort at 1-800-248-4628. They will find a convenient time to meet with you at your bam for sampling. The KDA. samplers will also rate your hay for several visual …

Management Options For Thinning Alfalfa Stands, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa "Queen of the Forage Crops", is the most important forage legume grown in the United States. It is widely adapted and is grown over a wide range of soil and climatic conditions. Alfalfa has the highest yield potential and highest feeding value of all adapted perennial forage legumes. It is a versatile crop which can be used for pasture, hay, silage, green-chop, soil improvements and human consumption (sprouts, etc.). As a result of this crops many merits, especially yield, quality and versatile use, it can be used successfully in many animal feeding programs.

Alfalfa Varieties, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Few areas of forage agriculture are changing faster than variety development in alfalfa. The 1990 revised "Alfalfa Varieties" publication of the Certified Alfalfa Seed Council listed 26 new alfalfa varieties. Of the available certified alfalfa varieties, only 10 to 15% are public varieties. The remainder are developed and marketed by commercial companies such as Agripro, Dairy land, FFR, Pioneer, Vista, W-L Research, and others. The need for yield and performance information on alfalfa varieties therefore increases yearly. In 1990, the alfalfa variety testing program was re-started under the leadership of the University of Kentucky and Western Kentucky University (WKU). Three …

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.

Genetic Variation In Endemic And Widespread Plant Species, Pamela S. Soltis, Douglas E. Soltis

Aliso: A Journal of Systematic and Floristic Botany

Population genetic theory and methodology were applied to the study of endemic plant species. Levels of genetic variability were compared between endemic species and their more widespread relatives. Six of seven narrowly distributed taxa of Saxifragaceae had significantly reduced genetic diversity relative to species of Saxifragaceae with broader distributions. Two endemic species of the fern Polystichum maintained significantly lower levels of genetic variation than did their more widespread congeners. The implications of these data and those reported for other endemic plant species for designing management strategies are also discussed.

Parallelism, It's Evolutionary Origin And Systematic Significance, K. Kubitzki, P. Von Sengbusch, H. Poppendieck

Aliso: A Journal of Systematic and Floristic Botany

Parallelism as one of the forms of biological similarity is investigated in the light of recent findings from developmental and molecular biology. From the organismic point of view, functional constraints and evolutionary canalization are well established as causes of parallelism. To these may be added, from the molecular perspective, (a) erratic activations of repressed genes; (b) activations of alternative pathways under the influence ofhomoeotic genes; and (c) horizontal gene transfer, for which a simple mechanism is proposed. The control of gene expression through the action oftransposable elements, reversible to some degree, appears to be an evolutionarily important and frequent phenomenon, …

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 …
