Improved Processing For High-Quality Seed Of Big Bluestem, Andropogon Gerardii, And Yellow Indiangrass, Sorghastrum Nutans, R R. Brown, J Henry, W Crowder May 2026

Improved Processing For High-Quality Seed Of Big Bluestem, Andropogon Gerardii, And Yellow Indiangrass, Sorghastrum Nutans, R R. Brown, J Henry, W Crowder

IGC Proceedings (1977-2023)

The recent reintroduction of native prairie warm-season grasses for livestock forage in the Corn Belt presents seed-handling problems with some species. Seeding big bluestem (Andropogon gerardii Vitman) and indiangrass (Sorghastrum nutans [L. J Nash) through commonly available seeding equipment is difficult with seed from commercial sources. Commercial seed contains significant amounts ofleaf and stem particles as well as awns and other appendages still attached to the seed. These seed append­ages and inert matter prevent an even flow of seed through the seeding equipment. Specially designed rangeland drills handle the seed rather well, but the limited use of this equipment makes …

Selection For Seed Retention In Phalaris Aquatica L., J R. Mcwilliam, C N. Gibbon May 2026

Selection For Seed Retention In Phalaris Aquatica L., J R. Mcwilliam, C N. Gibbon

IGC Proceedings (1977-2023)

Seed shattering is a problem in most pasture grasses, especially in those that have a history of recent domestication. In many of these grasses, losses from shattering are aggravated by uneven ripening of inflorescences and a low percentage of viable seed. Fragility of the rachilla appears to be the most common cause of seed shattering in grasses, and once this connection is broken, the seed is free to shed from the inflorescence. In some of the more domesticated species, the nature and configuration of the glumes and the manner in which they are packed on the inflorescence play an important …

Inefficient Conversion Of Floret Populations To Actual Seed Harvested In Grass-Seed Crops, K R. Brown May 2026

Inefficient Conversion Of Floret Populations To Actual Seed Harvested In Grass-Seed Crops, K R. Brown

IGC Proceedings (1977-2023)

Obtaining more than 34 machine-dressed seeds from every 100 florets in trials at Lincoln, New Zealand, was uncommon. In ryegrass (Lolium sp.), Grasslands Matua prairie grass (Bromus catharticus Vahl), and G17 cocksfoot (Dacrylis glomerata L.) crops, the larger the floret population, the lower the number of seeds obtained from every 100 florets. Nitrogen (N) improved the return, and in prairie grass the return increased as the rate ofN increased beyond 20 kg N/ha. In prairie grass, floret populations decreased as row spacings increased. With this seed, recovery was highest at wide row spacings, but in cocksfoot the reverse was true. …

Effect Of Different System Of Seed Treatment, Packing, And Storage On Vigor And Germination Of Five Tropical Forage Legumes, R Cabrales, J Bernal May 2026

Effect Of Different System Of Seed Treatment, Packing, And Storage On Vigor And Germination Of Five Tropical Forage Legumes, R Cabrales, J Bernal

IGC Proceedings (1977-2023)

Production of tropical forage·l􀂗􀂘me seeds is expensive. Very often, the establishment of mixtures is difficult because of lack of uniformity in vigor and germination of the legume seed. Treatment with chemical compounds has been reported to be useful in breaking dormancy. The packing material and temperature of storage have also been reported to affect seed vigor and ger­mination. The following treatments were applied to recently harvested seeds of tropical kudzu (Pueraria phaseoloides [Roxb.) Benth.), clitoria (Clitoria ternatea L.), centrosema (Centrosema pubescens Benth.), siratro (Macroptilium atropurpureum DC. Urb.), and desmodium (Desmodium intortum [Mill.) Fawc. and Rendle): concentrated sulfuric acid (96 % …

Seed Production For The Establishment Of Pennisteum Americanum X P. Purpureum F1 Hybrid Pastures, M E. Aken'ova, H R. Chheda

IGC Proceedings (1977-2023)

Several genotypes among the interspecific F 1 hybrids between Maiwa, a short-day, photoperiod-sensitive local cultivar of pearl millet (Pennisetum americanum [L.] Leeke), and elephant grass (P. purpureum Schumach) produced at the University of Ibadan, Nigeria, combine the high dry-matter yield potential and perenniality of elephant grass with greater acceptability to livestock and increased digestibility, resulting in higher live-weight gains than elephant grass. Though sterile, the Fr Pennisetum hybrids are easily propagated vegetatively. Distribution over a wider area of adaptation can be facilitated by large-scale F 1 seed production utilizing cytoplasmic male-sterile pearl millet. Cytoplasmic male-sterile Maiwa was developed by transferring …

Effect Of Autumn And Spring Defoliation And Defoliation Method On Seed Yield Of Lolium Perenne, P D. Hebbleethwaite, T.G A. Clemence

IGC Proceedings (1977-2023)

Trials in 1979 and 1980 evaluated the effect of autumn and spring defoliations on fertile apex removal, tiller survival, seed­yield components, and seed and forage yield in two amenity- and one agricultural-type perennial ryegrasses (Lolium perenne), established in the autumn. Methods (reciprocating mower or sheep), height (3-5 cm or 6-8 cm) of defoliation, and the addition of supplementary nitrogen (N) after defoliation were evaluated in the variety Royal in 1980. In both years and all varieties, autumn defoliation had no significant effect on seed yield. With the exception of Royal in 1980, seed yields were reduced by cutting, if it …

Post Residue As A Management Tool In Grass-Seed Production, D O. Chilcote, H W. Youngberg, W C. Young Iii May 2026

Post Residue As A Management Tool In Grass-Seed Production, D O. Chilcote, H W. Youngberg, W C. Young Iii

IGC Proceedings (1977-2023)

Postharvest residue burning, initiated in Oregon in the early 1940s to control blind seed disease in perennial ryegrass (Lolium perenne L.), has been found to be a most effective field sanitation method that also enhances seed yield. It is now a general prac­tice in Oregon, and its use is expanding to other regions. Questions of how burning beneficially affects grass-seed crop production have been the focus of many studies conducted over several years in the Willamette Valley. These studies were given impetus by the concern for clean air in certain locations in Oregon. The objectives of the research were (1) …

Trials On Time Of Nitrogen Application In The Spring To Various Grasses Grown For Seed Production, A Nordestgaard May 2026

Trials On Time Of Nitrogen Application In The Spring To Various Grasses Grown For Seed Production, A Nordestgaard

IGC Proceedings (1977-2023)

With most of the grasses grown for seed in Denmark, a series of trials has been carried out on increasing nitrogen rates in the autumn combined with increasing rates in the spring. The results of these trials show that an autumn application of nitrogen is very important to most of the grasses and necessary if the optimum yield of seed is to be achieved. In order to find the best time to apply nitrogen in the spring when producing grass seed, a number of trials have been carried out in recent years with various grasses. Up to and including 1980, …

Grassland Development In Japan And Other Asian Countries, I Nikki

IGC Proceedings (1977-2023)

Only since World War II has attention been directed to grassland injapan. Forage crops were introduced on dairy farms for feeding cattle . Acreages have increased and now equal 15 % of the total field area. Forage crops are second to :rice as a major crop . The New Grassland Law, approved in 1950, has led to "grassland improvement" and development of established pastures. J apa:n, situated in the most northern part of the Asian Monsoon Area, is warm as a rule and has much rainfall. Miscanthus sinen­sis Steud. and Zoysiajaponica Steud. are the dominant representative species of natural grassland. …

Resource Allocation For Animal-Grassland Systems, G W. Thomas May 2026

Resource Allocation For Animal-Grassland Systems, G W. Thomas

IGC Proceedings (1977-2023)

The production of animal products from grasslands is dependent upon an adequate resource base-particularly the availabil­ity ofland, water, and energy. In addition, range and pasture production systems must be designed to adjust to climatic varia­tions and to minimize adverse environmental impacts. Several new developments will have a significant impact on the future allocation of resources for animal agriculture: (1) in­creased competition for land and water, which is leading to transfers from agricultural to nonagricultural uses; (2) increasing costs and decreasing availability of "cultural energy" (particularly fossil fuels); (3) more pressure to divert grains and feed con­centrates from animals to direct …

Physiological And Morphological Advances For Forage Improvement, J P. Cooper May 2026

Physiological And Morphological Advances For Forage Improvement, J P. Cooper

IGC Proceedings (1977-2023)

Forage production basically involves the conversion of environmental inputs to provide digestible energy and other nutrients for ruminant livestock. The plant breeder needs to consider the seasonal inputs or constraints in his particular environment, the efficiency of the crop in responding to these factors, those features of the plant that contribute to this efficiency, and the degree to which those features can be modified by selection and breeding. Forage production basically involves the conversion of environmental inputs to provide digestible energy and other nutrients for ruminant livestock. The plant breeder needs to consider the seasonal inputs or constraints in his …

Multiple Use Of Grassland Resources (Grasslands To Provide Natural Resource Conservation And A Quality Environment For Mankind), P J. Edwards May 2026

Multiple Use Of Grassland Resources (Grasslands To Provide Natural Resource Conservation And A Quality Environment For Mankind), P J. Edwards

IGC Proceedings (1977-2023)

The grasslands of the world ( and communities closely akin to them, such as shrub and savanna types) provide not only a very effective mantle for protection of the soil, but also the main source of feed for herbivores. They also cater to many other needs of mankind. Increasing population results in competition between types of grassland use for specific sites. Sound planning is necessary to resolve this conflict in the way most beneficial to mankind. In order to plan logically it is necessary to make an inventory of the resources, to consider the various uses to which grasslands can …

Contribution Of Forages To Worldwide Food Production: Now And In The Future, E F. Henzell May 2026

Contribution Of Forages To Worldwide Food Production: Now And In The Future, E F. Henzell

IGC Proceedings (1977-2023)

Herbivorous livestock provided during the 1970s an estimated minimum 7%-17% of the total dietary protein in Asia and Africa compared with about 30 % in Latin America and just over 30 % in the developed countries. Cattle accounted for approx­imately 70% of the world's domestic animals (calculated in units weighted for size), buffaloes for 10%, and sheep and goats for 11 % . About 69 % of these animal units were in the developing countries, but productivity was higher in the developed coun­tries. Forages, defined broadly to include all edible plant materials except grains and concentrates, provided more than 90% …

Potential Productivity Of Temperate And Tropical Grassland Systems, G O. Mott May 2026

Potential Productivity Of Temperate And Tropical Grassland Systems, G O. Mott

IGC Proceedings (1977-2023)

Grasses of temperate regions of the world belong primarily to the subfamily Festucoideae, whereas tropical regions are populated by tribes of the Panicoideae subfamily. Temperate grasses have a C3 biochemical pathway of photosynthesis in con­trast to tropical grasses, which have a C4 photosynthetic mechan-ism. Both tropical and temperate legumes are C3 plants. Com­patible mixtures of legumes and grasses have long been successful in many temperate regions, but combining C4 grasses and C3 legumes as mixtures in the tropics has been only moderately successful. Maximum net primary productions of temperate and tropical grasslands are in the order of 25 and 80 …

Use Of Genetic Resources For Improvement Of Forage Species, J R. Harlan May 2026

Use Of Genetic Resources For Improvement Of Forage Species, J R. Harlan

IGC Proceedings (1977-2023)

The use of genetic resources of forage species poses some special problems because of the number of species involved, the in­adequacy of our knowledge about them, the fact that they are often used in combination and should be evaluated in terms of livestock product, and so on. Collections should be as comprehensive as possible at the outset of improvement programs; other­wise, there may be much use of inferior material and much waste of time and effort. Most of the forage species in use come from (1) Europe (excluding Mediterranean zones), (2) Mediterranean Basin and Near East, (3) African savannas (mostly …

Forage Quality: Assessing The Plant-Animal Complex, D J. Minson

IGC Proceedings (1977-2023)

At the VI International Grassland Congress held at Pennsylvania State College in 1952, the late Dr. C.P. McMeekan re­viewed the many problems associated with the plant-animal complex. Great stress was placed on the need to measure forage in­take accurately as a prerequisite to an under-standing of the plant-animal complex. Progress in the development of more accurate :methods of estimating the forage intake of grazing animals is reviewed, in­cluding the introduction of different methods of administering chromic oxide, the esophageal fistula for obtaining samples of selectively grazed material, the in-vitro technique for estimating the digestibility of the forage eaten, and the …

Competitive, Adaptive, And Evolutionary Process In Grassland Ecosystems, B D. Patil May 2026

Competitive, Adaptive, And Evolutionary Process In Grassland Ecosystems, B D. Patil

IGC Proceedings (1977-2023)

In the tropics, grasslands or grazing lands are found where the forest vegetation climax has been subjected to fire, grazing, felling, or other disturbances. Grazing lands in the tropics form various ecosystems under the major climatic types. Delineation of such ecosystems is possible through remnants of the climax vegetation of undisturbed or least-disturbed areas. Several subecosystems exist as seral stages under each ecosystem, the floristic composition of which is a reflection of the edaphic and soil­moisture-fertility conditions. Biological production in terms of energy for grazing animals varies among these ecosystems and subecosystems. Reconstruction of the adaptable competitive flora with woody …

Researcher Identity In Non-Conventional Research Settings: An Autoethnography, Irina Berry, Robin Hardin, Hunter B. Porter May 2026

Researcher Identity In Non-Conventional Research Settings: An Autoethnography, Irina Berry, Robin Hardin, Hunter B. Porter

Journal of Graduate Education Research

Scholars have emphasized reflexivity as a key practice for addressing potential biases and enhancing the credibility of research. Although reflexivity has been recognized as essential to qualitative rigor, limited attention has been given to its theoretical integration with broader social identity processes, particularly in non-conventional settings. This manuscript extends social identity theory and demonstrates how the insider/outsider model adds additional layer of complexity to the understanding of researcher identity negotiation. In this study, the researcher used an autoethnographic approach to examine the experiences of an able-bodied researcher conducting research in adaptive sport settings and featuring adaptive athletes. Strategies that emerged …

Exploring The Simultaneous Processes Of Academic Job Search And Dissertation For Culturally Diverse Doctoral Candidates In Counselor Education Programs, Galaxina G. Wright, Jasmine Griffith, Jasmine Garrison, Inga Antrobus

Journal of Graduate Education Research

Doctoral candidates face several challenges as they complete their academic journeys, particularly as it relates to the unique balance of applying for faculty positions while completing their dissertations. Though both processes have been explored separately within some educational fields, minimal research exists within the field of counselor education (CE) examining simultaneous experiences, particularly those from historically marginalized populations. Guided by the Career Self-Management (CSM) framework and an interpretive phenomenological analysis (IPA), we explored the perspectives of 11 CE candidates from historically marginalized backgrounds engaged in both processes. We identified five main themes and four subthemes that participants experienced. We discuss …

From Linear To Circular Transition: A Multi-Level Perspective On Waste Generation And Circularity Potential In Irish Hotels, Sahar Attari, James Hanrahan Dr May 2026

From Linear To Circular Transition: A Multi-Level Perspective On Waste Generation And Circularity Potential In Irish Hotels, Sahar Attari, James Hanrahan Dr

Irish Journal of Tourism, Hospitality, Leisure and Event Research

This study examines how the multi-stream waste composition of Irish hotels aligns with European Union circular economy targets and what this reveals about the sector's position within a linear-to-circular transition. It provides the first multi-stream waste benchmark for the Irish hotel sector and interprets the findings through a socio-technical transition lens. A cross-sectional waste audit was conducted across 30 Irish hotels, collecting full-year data on food waste, recycling, and general waste. Carbon emissions were calculated using life-cycle emission factors, threshold analysis derived empirically grounded typologies, and circularity gaps were quantified against the EU 2030 recycling target (65%). Findings were interpreted …

Self-Esteem Development And Emotional And Behavioral Disorders, Bahaa Al Ghraibeh May 2026

Self-Esteem Development And Emotional And Behavioral Disorders, Bahaa Al Ghraibeh

Archives of Assessment Psychology

Self-esteem is a fundamental psychological construct that develops across the lifespan and influences academic, social, emotional, and behavioral functioning. Research consistently links healthy self-esteem with positive developmental outcomes, including improved educational achievement, stronger interpersonal relationships, and better mental health. At the same time, emotional and behavioral disorders (EBD) are associated with persistent emotional, behavioral, academic, and social difficulties that can interfere with healthy self-development. This paper reviews the developmental trajectory of self-esteem from early childhood through adulthood and examines how the experiences commonly associated with EBD may negatively affect that trajectory. The review discusses how children begin forming self-esteem at …
