Defoliation Of Grass (Cut Or Grazed) And Its Effect On Forage Quantity, H C. Hughes Sep 2024

Defoliation Of Grass (Cut Or Grazed) And Its Effect On Forage Quantity, H C. Hughes

IGC Proceedings (1993-2023)

All grassland farmers should try to optimise their grassland output during the growing season. Grassland farmers would improve their production results if they paid more attention to plant defoliation processes. Careful management of the grass ley will increase outputs by more than one third, without needing further inputs. Most grassland farmers need to have this improvement with no additional cost, especially in the present world economy.

IGC Proceedings (1993-2023)

Alfagraze (grazing-tolerant) and Apollo (hay-type) lucerne (Medicago sativa L.) cultivars were stocked continuously with beef steers at 3 grazing pressures (GP) for 3 years In central Georgia, USA. Lucerne stands declined at the highest GP, Apollo stand density being only 23% of that of Alfagraze in grass-free areas at the end of 3 years. Rapid encroachment by volunteer bermudagrass (Cynodon dactylon (L.) Pers,) at high GP resulted in greater stand loss in Apollo than Alfagraze. Steer average daily'gain on both cultivars declined from 0.95 kg at low GP to 0.76 kg at medium GP with a further …

IGC Proceedings (1993-2023)

Pasture production in winter cold regions such as Atlantic Canada is limited by the availability of winter hardy and productive grass and legume species, Perennial ryegrass (Lolium perenne L.), meadow fescue (Festuca prarensis Huds.) and timothy (Phleum pratense L.) grown in binary mixtures with white clover (Trifolium repens L.), and naturalised pasture consisting of Poa spp., Agrostis spp. and white clover, were compared under grazing, Steers were used to graze the swards from 16-26 cm down to 8 or 11 cm post-grazing surface heights, Dry matter intake was higher for natural pasture than for sown pastures, …


Range Management: Optimizing Forage Production And Qualityy, J E. Danckwerts, N M. Tainton Sep 2024

Range Management: Optimizing Forage Production And Qualityy, J E. Danckwerts, N M. Tainton

IGC Proceedings (1993-2023)

Range management involves optimising forage production and quality, both in the short term and in the long term. In the short term, temporal climatic variability, stocking rate, grazing system, fire, animal type. and spatial variability, inter alia, strongly, influence forage production and quality. On the other hand, long-term optimisation requires prevention of range deterioration. The nature of this process seems to be profoundly different between humid and arid rangelands, at least in tropical and subtropical zones. In the former, changes are relatively predictable, overgrazing resulting in gradual deterioration. In the latter, change is event driven, providing the grazier with …


An Ecological Approach To Forage Management, J L. Brock, R.J M. Hay Sep 2024

An Ecological Approach To Forage Management, J L. Brock, R.J M. Hay

IGC Proceedings (1993-2023)

The principles of defoliation management for maximum production of quality herbage are well researched, namely the manipulation of frequency and severity of defoliation, but their impact on the various levels of ecological organisation in pastures is nol fully understood or their interpretation appreciated. Using grazed ryegrass-white clover pasture as; example, detailed sward studies have suggested the following model. Defoliation frequency and severity interact lo produce varying levels of physiological stress and morphological adaptation which affecl the survival rate and size of individual growth units, the lowest level of organisation. Increasing frequency of defoliation reduces organ size but increases survival rate …


Land Use In Non-Affluent Countries As Determined By Social Infrastructure And Population Patterns, Bore Motsamai Sep 2024

Land Use In Non-Affluent Countries As Determined By Social Infrastructure And Population Patterns, Bore Motsamai

IGC Proceedings (1993-2023)

Tenure of land in most developing countries is predominantly communal, with a mixture of introduced systems of individual ownership. Since nations attained independence structural- changes have been made in order to introduce land reform. Countries are caught up in a dilemma of having to provide social justice and greater equity through land reform, but face increasing population and landlessness. For example, Lesotho's landless rural people increased from 7.2% in 1950 to 38.5% in 1987, and 17.2% are without land and livestock. Employment opportunities fall short of satisfying the labour mBrket. With limited land resources and high population pressure, rational and …


The Future Of Sustainable Agriculture In The United States, Dennis R. Keeney Sep 2024

The Future Of Sustainable Agriculture In The United States, Dennis R. Keeney

IGC Proceedings (1993-2023)

In the United States, sustainable agriculture remains complicated and controversial as a concept, particularly to define and apply in terms of practices and policies to achieve sustainability. Many consider current agricultural practices to be sustainable in the near term with regard to the dependable, affordable supply of food and fibre, but unsustainable in terms of environmental quality and social costs. Production agriculture hos been linked to soil erosion and water pollution, and the emphasis on efficiency has contributed to the loss of many farmers and increasing instability in rural communities. Many of agriculture's dilemmas can be linked to policies of …

Livestock Production Systems In The Cameroon Sahelo-Sudanian Region, E Tedonkeng Pamo, R D. Pieper

IGC Proceedings (1993-2023)

The Sahelo-Sudanian region of Cameroon extends from 7° to 13° N. The region receives 400-1000 mm rainfall and is covered by a complex mosaic of. vegelation and plant communities. Animal production has always been a cornerstone of the economy of this region. The range use system of the region is extensive. The major problem faced by pastoralists has been a compression of their range not only by the northward-moving cultivation, but also by the southward moving desertification. Various grazing melhods have been suggested but none have yet been implemented, and nomadism and transhumance remain the major production systems. Analysis of …


Runoff Studies In Different Cropping Systems And Preliminary Results For Nitrogen Leaching, Ragnar Eltun Sep 2024

Runoff Studies In Different Cropping Systems And Preliminary Results For Nitrogen Leaching, Ragnar Eltun

IGC Proceedings (1993-2023)

A cropping system project was started at Apelsvoll Research Station in 1990, with the aim of developing cropping systems to minimise nutrient leaching and maximise food quality and economy. The experiment involves cash crop and forage crop systems with conventional, integrated and organic farming. This paper presents the experimental layout and preliminary measurements of nitrogen leaching. Both drainage water concentrations and runoff results shows that nitrogen leaching is less from cropping systems dominated by forages than from cash crop systems with cereals and potatoes.

Land Subdivision In The Falkland Islands, O W. Summers, W.J R. Haydock, A Kerr

IGC Proceedings (1993-2023)

The Falkland Islands agricultural industry depends mainly on wool production. This paper reviews the structure of an induslry which has changed radically in the last 10 years. Lord Shackleton completed his economic survey of the Falkland Islands in 1976 when there where only 36 fanns, most of which were owned by companies based mainly in the UK, and an absentee-landlord system prevailed. Shackleton advocated that the Falkland Islands Government should purchase large fanns and split them into smaller family units for sale to local people. Presently (1991-92) there are 92 farms and most of the Islands is in local ownership. …

IGC Proceedings (1993-2023)

Extensive beef production, Namibia's life-line in agriculture, depends entirely on natural pastures. Socioeconomic and environmental disparities, namely (a) the· traditional smallholder communal sector versus the commercial sector and (b) areas in the vicinity versus distant from centralised abattoirs, are analysed by' using econometric analysis of time-series data on the regional influence of prices and· access to markets on beef numbers. This is particulary relevant because Namibia is in a process of structural adjustment, and in view of the beef sector's importance in the Namibian economy. The results accentuate the role of access to markets and productive opportunities for beef production …

Reduction Of Nutrient Losses For Dairy Farms, With Emphasis On Nitrogen, W Luten, D J. Den Boer

IGC Proceedings (1993-2023)

Recently the Dutch government presented several policy papers in which standards are given for maximum allowed emissions to air, groundwater and surface water. Depending on the farm situation an optimum combination of measures in relation to housing, slurry storage, slurry and fertiliser application, and composition of the ration can be taken. In general a better use of nutrients from animal manure by applying slurry with low emission techniques in the growing season and a reduction of the stocking rate by a higher milk production per cow are the most effective and cheapest measures to reach these targets. There is a …

Pastoral Systems Of Central Himalaya: How Long Will They Survive?, K S. Rao, K G. Saxena Sep 2024

Pastoral Systems Of Central Himalaya: How Long Will They Survive?, K S. Rao, K G. Saxena

IGC Proceedings (1993-2023)

Pastoral systems of Central Himalaya are very old and until recent time were in balance with environment, Recent changes in socio­political setup have drastically altered the status of these systems. The change of political power in trans-Himalayan Tibetean plateau has resulted in closure of international boarders, thus taking away the mercantile aspects of pastoralists and reducing pastoral area. Increased human disturbances on fragile Himalayan marginal lands and excessive onslaught on forests for fuel and fodder by the sedentary population has resulted in degradation and non-productive grasslands which do not help pastoralists sustain existing systems. Changes in relations between migratory pastoralists …

Sustainable Direction For Resource Management An Assessment Of The Regional Council Role, Allan Lohrey

IGC Proceedings (1993-2023)

The 1980s has seen an increased world awareness of the concept of sustainability. In 1991 New Zealand enacted the Resource Management Act (RMA) which reflected society's concern for a need to consider future generations when making decisions relating to the use of natural resources. Regional councils have been allocated the role within the Act to promote sustainable management at the regional level. The short term challenge to regional councils is to manage resources in manner which strikes a pragmatic balance between the ongoing needs of society and the need to provide resources for future generations. Regional councils will know they …
