Proximate Composition Of Mature Seeds From Soybean Plants Grown In Different Environments, T M. Kuo, E Eskins, R L. Cooper

IGC Proceedings (1977-2023)

The objectives of this study were to examine the influence of differences in sunlight irradiation on the accumulation of soluble oligosaccharides in mature soybean (Glycine max L.) seeds and to determine the correlations between important seed constituents. Plants were grown in field houses covered with plastic filters that varied sunlight irradiation. The most obvious effect of both blueand red-deficient sunlight was a reduction in the level of stachyose and sucrose that coincided with an increase in raffinose level and decreased oil content. Blue growth house which was deficient in red light spectrum also produced seeds with an increased protein content. …

Arthropods, Silvertop, And Grass Seed Yields, J J. Soroka, B D. Gossen, B E. Coulman

IGC Proceedings (1977-2023)

High numbers of various arthropods early in the season, especially thrips, mites, and grass plant bugs, were associated with silvertop injury in six grass seed fields in Saskatchewan in 995. Insect numbers in sweep samples were frequently suppressed for one or two weeks in plots sprayed with an insecticide. Four fields had low levels of arthropods early in the season andoelow incidence of silvertop later on. In a field of Russian wildrye grass with high arthropod populations, seed yield was highest in plots that had been sprayed with insecticide prior to the boot stage of grass growth. In one field …

The aim of this study was to determine the germination conditions as well as an approach to seed quality of five native grasses of the humid Argentine Pampa prairie: Bothriochloa laguroides, Sporobolus indicus, Glyceria multiflora, Briza subaristata and Chaetotropis imberbis. They are considered as good and very good forage species. Mature inflorescences were sampled in Brandsen (Flooding Pampa sub-Region, Buenos Aires province, Argentina) from December, 1994 to March, 1995. A three factor completely randomized design with 4 replications was applied. Treatments combined prechilling (I: yes/II:no), KNO3 (A:yes/ B:no) and germination temperatures: 2 constant 15° and 20°C and 6 alternating 15-10°C, …

Alfalfa Seeding Patterns And Their Relations With Vegetative And Reproductive Development, R B. Medeiros, A.V A. Jacques, C Nabinger

IGC Proceedings (1977-2023)

This study was conducted to understand how plant density (17, 61 and 89 plants m-2) and row spacing (30 and 90 cm) affect plant development and the consequences on potential seed yield (PSY) and agricultural realized seed potential (ARSP) of alfalfa (Medicago sativa L.) in south Brazil. Both variables were not affected by row spacing but were negatively correlated to plant population. This was a consequence of a higher allocation of assimilates to reproductive structures at low plant competition, denoted by a positive correlation between these two variables and reproductive parts growth rate. Despite the benefits of the low plant …

Applying Student-Centered Strategies In The Applied Teaching Music Studio, Jeanne Goffi-Fynn

Visions of Research in Music Education

Applied studio instruction is a field of education set in the context of a one-to-one setting, traditionally seen as a master-apprentice model, where the “training of skills” is said to be a priority. However, as the field evolves and is influenced by other areas in teaching and learning, one begins to look for ways to apply student-centered or constructivist strategies to the music studio. In this article, we will look broadly at what it means to be student-centered in the music studio, breaking down the areas into five categories of rapport, motivation, critical thinking, content specific areas such as practice, …

Effects Of Cutting Height On Yield And Quality Of Five Napier Cultivars, S T. Jorgensen, S Tudsri, A Pookpakdi, O Stolen

IGC Proceedings (1977-2023)

Results of this experiment revealed that dry matter yield of five Napier grass species increased with higher stubble and that a delay in closing date had produced a negative effect on regrowth for the following season, especially, when low cutting height had been imposed. The nitrogen and phosphorus percentage in leaf and stem materials were not affected by cutting height. Potassium percentage and NDF% were lower for herbage with 0 cm cutting height compared to 30 cm cutting. Among the different cutting intensities, 20 cm and 30 cm cutting height can be recommended through the growing season.

Perception Of Rangeland By Herders In Northern Cameroon, E Tedonkeng Pamo, P Scholte

IGC Proceedings (1977-2023)

Range scientists have always had the mistaken idea that herders cannot appraise, characterize or assess the state of their rangeland or range resource. From observations made in northern Cameroon, it appears that herders know the pastoral environment in which they operate probably better than many range scientists. They do not seem to have a good idea on range trends. However, from their pattern of range utilization over time it is possible to have an assessment of the state and trend of rangeland. A wide range of information on the pastoral knowledge of rangeland is needed to develop a sustained range …

A thematic map of grassland has been drawn up using studies carried out at farm level as a starting point, correlating soils and specie group through significant parameters that condition their presence. The work method included the analysis of a geomorphologically homogeneous area through cartography and aerial photography. An elemental unit of the landscape was studied in detail with a pattern repeated all over the subregion, with soil samples at specie group level. Hidromorphism and variable alkalinity and saline patches are present in all profiles, gramineous, juncaceous, cyperaceous and forbs linked to the problems of soil already mentioned. A system …

Restoration Of Degraded Coastal Grasslands In The Falkland Island, J A. Kerr

IGC Proceedings (1977-2023)

In the Falkland Islands the coastal grasslands are the most valuable for wool production and important habitats for wildlife. Tussac grass (Parodiochloa flabellata Lam.) and sandy areas which support an Ammophilia - Elymus association have been degraded by overgrazing, burning and invasion by alien flora and fauna. Traditional approaches to restoration, mainly by replanting, have had limited success. Research on

Grassland N Fertilization In Humid Tropics: Production, Organic Matter Decomposition And Uptake, G Mandret, V Blanfort

IGC Proceedings (1977-2023)

Under tropical humid conditions at low altitudes in La Reunion island an experiment was conducted in 1995 to examine the effects of mineral and organic N fertilisation on regrowth of Chloris gayana . Mineral fertilisation stimulates the production of leaves for the first 20 days of regrowth. Dry matter production was increased of 181 % with the combination of manure plus ammonium nitrate and only 147 % with ammonium nitrate alone. The soil microbial biomass activity, measured after 50 days of regrowth, was increased of 31 % by application of manure, 41 % by ammonium nitrate and 50 % by …

A Study Of Agronomic Factors Affecting The Yield And Quality Of Forage Maize In Ireland, G P. Keane

IGC Proceedings (1977-2023)

The objectives of these studies were to examine the effects of sowing date and plastic film on the yield and quality of forage maize (Zea mays L) in a marginal maize growing area. The response, in DM yield terms, to sowing in early April rather than early May differed in 1995 and 1996, but early sowing in all cases improved quality parameters. The use of plastic film, whether perforated or complete cover treatments, gave substantial yield increases in some instances, and always improved quality parameters. Perforated plastic gave highest DM yield increases with late April or early May sowings, …

Potential Of A Novel White Clover/ Cereal Bi-Cropping System For Whole Crop Forage Production, N Koefoed, R O. Clements, J Burke, G Donaldson, G Purvis

IGC Proceedings (1977-2023)

A novel low input system for growing cereals, so far mainly winter wheat (Triticum aestivum L), in close association with white clover (Trifolium repens L), is being developed currently, co-operatively by five research stations in northern Europe. An established sward of pure white clover is defoliated in the autumn and winter wheat drilled into it using a rotary type direct drill. After silage or grain harvest of the cereal/clover mixture the clover regrowth may add to the productivity of the system until defoliation and drilling-in of the next cereal crop takes place. With the system described dry matter …

Structure, Productivity And Animal Utilization In A Communal Pasture In The Basque Country (Northern Spain), I Albizu, G Besga, M Rodriquez, M Onaindia, M Domingo, I Amezaga

IGC Proceedings (1977-2023)

The goal of this study was to determine the structure, productivity and utilization of mountain communal pastures of the Gorbea area in 1994. The area was classified in four zones according to topographic position and improvement activities: north slope brush removed, summit, south slope 50% brush, and south slope brush removed. Ecological profiles were used to relate the most abundant species to soil P and K contents at the different zones. Exclosure cages were used to estimate potential productivity, botanical composition and pasture utilization. Soil P and K contents are the parameters that relate best to floristic composition, being Agrostis …

Recent Developments In The Use Of Near Infra-Red Spectroscopy For The Evaluation Of Grass Silage, N W. Offer, D S. Percival, C Thomas

IGC Proceedings (1977-2023)

This work assessed the potential of near infra-red spectroscopy (NIRS) to predict the voluntary intake and fermentation characteristics of grass silage. NIRS spectra were obtained from dried milled (Dry) or fresh samples by two methods (Wet1 - vertical transport mechanism and Wet2 - rotating cup drawer). Prediction errors (SECV as a percentage of mean values) were 5.5, 6.5 and 2.5 for Dry, Wet1 and Wet2 respectively for intake by dairy cows (n=28). Corresponding values were 10.3, 16.1 and 10.9 for lambs (n=88). The Wet2 method gave more accurate predictions than Wet1 except for predictions of ADF and unfermentable metabolisable energy …

Herbage Quality At Continuous Grazing With Dairy Cows At Different N-Intakes And Sward Types, K Soegaard, O Aaes

IGC Proceedings (1977-2023)

Herbage quality was examined in paddocks continuously grazed by dairy cows fed supplements with low and high N. There were two sward types for each level of supplement, i.e. fertilized perennial ryegrass (Lolium perenne L) and unfertilized perennial ryegrass/white clover (Trifolium repens L) with a mean clover content of 49 % of dry matter. Decreasing N-intake from 307 to 140 g N cow -1 d -1 by feeding low-N supplements had a small influence on herbage quality in spite of the reduced N-output via urine and faeces. Variation in herbage quality was large during the growing season. The fibre concentration …

Effect Of Calcium Nutrition On The Formation Of Calcium Oxalate In Kikuyu Grass, J P. Marais, A D. Barnabas, D L. Figenschou

IGC Proceedings (1977-2023)

The objective of this investigation was to study the formation of calcium oxalate crystals in situ in kikuyu grass (Pennisetum clandestinum) and to determine the effect of calcium uptake on the soluble and insoluble oxalate content of the grass. Oxalate crystals were more abundant in high-calcium leaves than in low-calcium leaves. Electron microscopy showed that the oxalate crystals are formed in association with globular electron-dense bodies in the vacuole of certain cells. The calcium content of kikuyu is increased by increasing the calcium level of the growth medium. However, the increased amount of calcium taken up by the …

Genetic Variation In Perennial Ryegrass For Volatile Fatty Acid Production In Rumen Fluid, H.J P. Marvin, E N. Van Loo, O Dolstra, C.H A. Snijders, D Reheul, J W. Cone

IGC Proceedings (1977-2023)

In perennial ryegrass genetic variation was shown not only for in vitro organic matter degradation (OMD) in rumen fluid and neutral detergent fibre content (NDF) but also for production of volatile fatty acids (VFAs) upon in vitro incubation in rumen fluid. The correlations among concentrations of VFAs in the incubation fluid were high. OMD and NDF, on the other hand, were poorly correlated to the VFA concentrations.

Characterization Of Legume And Grass Residues Following In Vitro And In Sacco Ruminal Digestion, D.J R. Cherney, J H. Cherney, A H. Davidson

IGC Proceedings (1977-2023)

Objectives were to characterize the influence of forage species and maturity on dry matter degradation. Averaged across maturities, alfalfa and red clover were lower in NDF content (39 and 30% NDF, respectively) than reed canarygrass and timothy (59 and 54% NDF, respectively). The NDF of the DM residues in grass remained relatively unchanged over time, while NDF of the DM residue in legume increased rapidly for 9 h before becoming relatively constant. Alfalfa incubated in vitro (42% NDF) compared to reed canarygrass (58% NDF) contained more ND soluble material (39% vs. 25%), and more pepsin soluble material (22 vs. 18%). …

IGC Proceedings (1977-2023)

The objective was to determine the effect of protein degradability and supplement level on forage degradation. Steers fistulated were utilizated in brachiaria (Brachiaria brizantha) pasture. A randomized block design was used with a control treatment and supplements according to a factorial scheme combining low, medium and high protein degradability with supplementation levels: low, medium and high analysed as principal treatments and incubation time as splitplot by SAS. Nylon bags were incubated at 4; 8; 12; 24; 48; 72; 96 and 120 hours to determine DM, CP and NDF degradation. There was no effect (P>0.05) of protein degradability …

Energetic Feed Value Of Grassland Products In Ruminants, A Chudy

IGC Proceedings (1977-2023)

A method for calculating the energetic feed value, based on the digestible nutrients and on the relations of the utilisation of the energy of the nutrients (carbohydrates = 100) for ATP syntheses is described. This relative scale is a nominal feed value (NFV). It characterises the ATP potential of the feedstuffs and is therefore equivalent to the efficiency of utilisation of the feed energy in the catabolic metabolism (non-thermal maintenance, muscular work (movement)) and energy costs for syntheses as well as the productive performance as energy retention in animal products. Therefore this scale secures a precise precognition of the animal …
