Method For Obtaining Better Germination Of Green Panic (Panicum Maximum Var. Trichoglume Eyles) Seed, T Okada
Method For Obtaining Better Germination Of Green Panic (Panicum Maximum Var. Trichoglume Eyles) Seed, T Okada
IGC Proceedings (1977-2023)
Because germination of green panic seed was unstable, a series of tests were performed to establish methods for obtaining better germination of this seed earlier than usual after it is harvested. In this report key points of the methods formulated are described. Seed ripened at 21 °C showed a higher germination percentage in its early age ( 4 months after harvest) than that ripened at 25°C or 29°C. Excellent early age germinations were realized by drying seed slowly immediately after harvest, especially by spending as much as a month gradually drying seed at 20°C and stirring every few days. Heating …

Economics Of Producing Corn (Maize) And Sorghum As Feeds For Animal Production In China, Bingxing Zhang
IGC Proceedings (1977-2023)
Due to insufficient production of animal products the Chinese people have eaten too much grain and too little meat and milk. Now, as a result of burriper harvests for several years in succession, it is time for the Chinese peasants to convert their surplus grain into feeds for the development of animal production to meet the growing needs of the Chinese people for meat and milk on the one hand and for wool and leather on the other. At the same time more forage sorghum and corn should be grown, especially on unused or misused poor lands and wide hillsides …

Effects Of Nitrogen And Potassium Fertilization On Dry-Matter Production, Nutrients Uptakes And Competitive Relation In Mixed Culture Of Forage Sorghum And Soybean, Y Kawamoto, Y Masuda, I Goto
IGC Proceedings (1977-2023)
The effects of nitrogen and potassium fertilization were examined on dry-matter production, N, P, Ca, and Mg contents and competitive relation for the nutrients uptakes in mixed culture of forage sorghum and soybean. The nutrients contents. of sorghum in mixed culture tended to be high under nitrogen or potassium fertilization, in comparing with those in pure culture. The density exchange rate of sorghum was less than 1.0, and that of soybean was greater than 1.0. It was suggested that inter-specific competition for sorghum and intra-specific competition for soybean showed greater effects on dry matter production and nutrients uptakes of individual …

The Effects Of Deep Incorporation Of Sewage Sludge And/Or Limestone On The Physical And Chemical Properties Of Acid Gob For Revegetation Of Grasses, J H. Jones, F J. Olsen
IGC Proceedings (1977-2023)
It is very difficult to establish and maintain vegetation on acid gob ( the coarse waste materials resulting from washing coal) sites. A study was conducted to determine the effects of varying rates of sewage sludge and/or limestone incorporated to 30 and 60 cm depths on the physical and chemical properties of gob for the establishment of grasses. The experimental site was located at Peabody Coal Company's Will Scarlet mine, Williamson County, Illinois, USA. The incorporation of sewage sludge as an amendment to acidic, low fertility and droughty gob resulted in favorable increases in organic matter, pH and reduced bulk …
The Differences In Surface Runoff And Soil Loss Between Vertical And Horizontal Cattle Tracks In Inclined Grasslands, M Oikawa, K Okamoto, Y Ogawa
The Differences In Surface Runoff And Soil Loss Between Vertical And Horizontal Cattle Tracks In Inclined Grasslands, M Oikawa, K Okamoto, Y Ogawa
IGC Proceedings (1977-2023)
The amount of surface runoff water and soil loss produced by artificial rainfall were measured in the grasslands where vertical and horizontal cattle tracks sharply developed, in order to establish the suitable design of paddock and the arrangement of water or salt sites that reduce the inclined grassland to erode. In mountainous grassland with steep slopes, grazing cattle take the nearly same routes which were determined by the degree of inclination and the locations of fences, water and salt sites or camping sites. The routes were gradually denuded of vegetation and formed many paths called "Ushimichi (in Japanese)", and were …
Loss Of Nutrients In Surface Runoff From Grassland Treated With Pig Slurry, M Sherwood
Loss Of Nutrients In Surface Runoff From Grassland Treated With Pig Slurry, M Sherwood
IGC Proceedings (1977-2023)
Soil physical limitations and climatic conditions in some countries make landspreading of manures a potential environmental hazard due to the danger of surface runoff to waterways. Pig slurry at two application rates was spread on sloped grassland plots at three sites with different soil drainage properties. All surface runoff water was collected and analysed after each significant rainfall. At Sites 1 and 2 where the first runoff event occurred within 48 hours of spreading, the runoff water contained very high concentrations of nitrogen (N), phosphorus (P), potassium (K) and BOD (Biochemical Oxygen Demand), which were related to the rate of …

The Grassy Ticket In The Northern Part Of China, Zhou Guangyu, Ye Zhengfeng, Li Xianggan
IGC Proceedings (1977-2023)
Grassy thicket is a main vegetation which is distributed in those provinces in the mountain-hilly region along the Qinling Mountain-Huai River and Great Wall, after the forests have been destroyed. The floristic composition of the grassy thicket community consists of 9-31 species. The dominant plants are grassy and mixed with shrubs. The major factor which affects the community is soil moisture content. The biomass of its fresh weight above-ground is mean 102. 7Kg/mu; the stocking rate is mean 25 .38mu/sheep/year. Under a well covered grassy thicket, the mould of soil-water erosion is 2700t/Km2, whereas when the plant community is destroyed …
Investigations On The Ecology And The Forage Value Of A Sheep Grazed Skiing Slope, G Spatz, G J. Park
Investigations On The Ecology And The Forage Value Of A Sheep Grazed Skiing Slope, G Spatz, G J. Park
IGC Proceedings (1977-2023)
The influence of sheep grazing and fertilization on the vegetation of a steep skiing course was investigated within the northern calcereous Alps from 1979 to 1983. When measuring vegetation dynamics, we made use of the Relevemethod, the Point-Intercept-method and the Quadrat-Charting-method. Good grasses and legumes increased their biomass portion, whereas sedges almost disappeared. So the fodder value of the original pasture improved due to sheep grazing and fertilization. The vegetation which was injured by heavy skiing regenerated best after fertilization and restricted grazing. Thus sheep grazing proved to be a good measure for taking care of skiing grounds and for …

Managerial Characteristics Of The Grassland Type Dairy Farming In Hokkaido, Japan, Y Miyazawa
IGC Proceedings (1977-2023)
Hokkaido is the northernmost island of Japan with an area of about 78,500 km2 and lies between 41 ° and 46°N. Dairy farming in Hokkaido, being endowed with vast land resources, has overcome severe climatic conditions and expanded its scale of operations through such measures as developing and improving grassland. Its main type of dairy farming can be said to be of the-grassland-type and the feeding resources of which depends mainly on pastures. The dairy farming in Hokkaido, therefore, is represented by this grassland-type that is one of the alternative types to be developed under comparatively unfavorable land conditions, such …

An interdisciplinary project, designated as Comprehensive Cow-Calf Management Demonstrations, was initiated by a term of extension specialists to demonstrate recommended management practices for cow-calf producers. The team consisted of extension specialists in beef cattle, agronomy and veterinary science. Cooperators for comprehensive on-farm demonstrations were nominated by county extension agents for agriculture and local veterinary practitioners. Selected cooperators were using a minimum of recommended practices but exhibited a willingness to make suggested changes. Farms were inventoried initially for cattle number and condition, soil capability and fertility, and existing facilities. Farm plans were then developed that would permit utilization of available resources …
Weight Gains And Nutrition Of Cattle Grazing On Grasslands Of Central Interior British Columbia, Canada, D A. Quinton, L Stroesser, H Douwes
Weight Gains And Nutrition Of Cattle Grazing On Grasslands Of Central Interior British Columbia, Canada, D A. Quinton, L Stroesser, H Douwes
IGC Proceedings (1977-2023)
Average daily gains and nutrient deficiencies of cattle grazing three grassland zones in British Columbia are shown. Cattle production was greatest on the rough fescue (Festuca scabrella) -bluebunch wheatgrass (Agropyron spicatum) association and least on the big sagebrush (Artemisia tridentata) -bluebunch wheatgrass association. Nitrogen (N), phosphorus (P) and magnesium (Mg) concentrations in cattle diets generally paralleled cattle gains. Increases in these nutrients in forages correlate to increased cattle gains. Depressed weight gains, poor growth of calves, late estrous cycling of cows, and white muscle disease of calves are all livestock symptoms associated with nutrient deficiencies of cattle …

Yield And Regrowth Characteristics Of Alfalfa Grazed By Sheep In Spring And Summer, V G. Allen, D D. Wolf, J P. Fontenot
IGC Proceedings (1977-2023)
Grazing alfalfa (Medicago sativa, L.) would provide high quality pasture in animal production systems. The influence of grazing alfalfa with sheep in early spring or in summer on regrowth characteristics, weed encroachment, and subsequent yields was investigated during two years and on hay yields during year 3 with no grazing imposed. Alfalfa was grazed in spring for 0, 2, 4, and 6 weeks at two grazing pressures: light (LAI of 1.0) and heavy (LAI< 0.5). Non-grazed alfalfa was harvested at late bud stage. Regrowth on all systems was harvested at 1/10 bloom. Grazing for 6 weeks reduced subsequent hay yield only in year 2. Heavy grazing pressure increased weed encroachment but weeds were effectively controlled with herbicides. Few residual effects were measurable in year 3. Another planting of alfalfa was grazed in summer following two hay cuts by five systems: 1), 2), and 3) grazed about 14 days after second hay cut for 2, 4, and 6 weeks, respectively; 4) grazed at early bud stage for 7-10 days; 5) grazed at early bloom for 7 days. For system 6, alfalfa was not grazed and hay was cut at 1/10 bloom. Following grazing, hay was cutif regrowth reached 1/10 bloom stage. Grazing for 2, 4, and 6 weeks linearly decreased fall regrowth and increased weed encroachment. In year 3, yield was reduced by grazing except at early bloom but differences were slight by August. Weed encroachment tended to increase with grazing duration. These data indicate that alfalfa is more tolerant of grazing in spring than summer. If weeds are controlled, extended grazing durations appear possible.

Preliminary Report On Experiment Of Winter Rotational Grazing Of Local Cattle, Lu Wengao, Lai Zhiqiang
Preliminary Report On Experiment Of Winter Rotational Grazing Of Local Cattle, Lu Wengao, Lai Zhiqiang
IGC Proceedings (1977-2023)
In winter, grass growth declines sharply and animal's demand increases with the passage of time. In Dec., affected by frostbite and low temperatures, pasture output drops greatly and cannot meet the needs of cattle. For this reason, in Nanning, late Dec. is considered the winter grazing in a critical period (WGCP). Huts and shelters should be put up in the areas where animals should continue to graze throughout the winter. It is relatively economical to give animal supplementary feeding started in late Dec.
