Effect Of Tree Species And Density On Pasture Production In Galicia, Spain, A. Rigueiro-Rodríguez, E. Fernández-Núñez, M. R. Mosquera-Losada
IGC Proceedings (1977-2023)
Galicia produces 50% of the forest products of Spain. Livestock production earns 62% of the income of the agrarian sector in Galicia. Afforestation has been very important in the last decade to such an extent that the area of forest and woodlands now covers 62% of Galicia. It is necessary to increase the rate of return on investments in planted forests in order to avoid rural depopulation through improvement of rural development and welfare. This paper reports on the effect of combining pastures with trees.

Evolution And Ageing Of Brachiaria Brizantha Pasture Component In A Silvopastoral System, M. Rakocevic, F. C. De Oliveira, J. Ribaski, O. J. Lavoranti
IGC Proceedings (1977-2023)
The main causes of the decline of Brachiaria pasture in the tropics are lack of maintenance, fertilisation and excessively high animal stocking rates (Boddey et al., 2004). Brachiaria brizantha has two predominant morphological forms: 1) relatively high stems with grouped tillers at a high position constructed from short leaves (bunch type); 2) low stems with long leaves, which in time evolve into the first type (Kanno et al., 1999). The concept of Brachiaria management involves animals entering to commence grazing when the pasture is 50-60cm high and being removed at 25-30cm, leaving a regrowth period of at least …

The Influence Of Tree Thinning And Tree Species On The Dry Matter Yield Of Grasses Of A Bush Encroached Semi-Arid Savanna In South Africa, G. N. Smit
IGC Proceedings (1977-2023)
The Acacia erubescens-Combetum apiculatum dominated savanna of South Africa is water-limited and an increase in woody plant abundance suppresses the grasses. This is the major reason why thinning or total clearing of all woody plants is often considered by landowners. The objectives of this study were to investigate the influence of intensity of tree thinning and tree species on grass yields in a semi-arid South African savanna.

Productivity Of A Leucaena Leucocephala-Cynodon Nlemfuensis Silvopastoral System With Sheep In Yucatan, Mexico, J. G. Escobedo-Mex, L. Ramirez-Aviles
IGC Proceedings (1977-2023)
Animal production in the tropics of Mexico is based on grazed grasslands of low productivity; this type of production system has reduced the areas of natural vegetation and damaged the ecology (erosion of flora, fauna and soil). Silvopastoral technologies may improve the welfare and economic conditions of the rural population and, consequently, preserve their natural resources. The current work was designed to assess the introduction of Leucaena leucocephala in a silvopastoral system with Cynodon nlemfuensis (star grass) grazed by sheep.

Optimising Forage Production On Degraded Lands In The Dry Tropics Through Silvopastoral Systems, P. S. Pathak
IGC Proceedings (1977-2023)
In India, 187 M ha out of a total area of 328 M ha face the problem of land degradation, mostly due to water and wind erosion. The problems are aggravated by poor land cover and increasing pressure of human and livestock populations. There is over-exploitation of the scarce resources of forage and firewood. Several techniques, including watershed based silvopastoral land use have been proposed (Patil & Pathak, 1977). Tree, grass and legume based systems have been tried after land treatment to reduce runoff and soil loss while meeting the forage needs of the livestock and firewood for cooking in …

Department of Agronomy and Horticulture: Faculty Publications
Tepary bean (Phaseolus acutifolius A. Gray) is an underutilized drought tolerant annual legume, originating from the Sonoran Desert, that may be a beneficial forage/hay for beef cattle in the Southern Great Plains of the US (SGP). The SGP has erratic rainfall and periods of intermittent drought exacerbated by high summer temperatures. In 2020 and 2021, a split-plot design was used to evaluate 13 genotypes of tepary bean and a forage soybean (control) at El Reno, OK, USA to compare production of plant biomass and forage nutritive value parameters under seven harvest regimes. Genotypes were used as the main plot …

Impact Of Soil Moisture Stress At Different Phases Of Corn Growth And Development, Ranadheer Reddy Vennam
Theses and Dissertations
Suboptimal soil moisture during the growing season often limits growth and yield potential of corn. This study aimed to assess the impact of varying soil moisture regimes on corn growth at different growth phases involving vegetative, flowering, and grain-filling stages. Exposure to moisture stress (80% of the control) during the vegetative stage resulted in a 65% reduction in stomatal conductance and increased the canopy temperature by 5 oC, which led to a substantial decrease in total dry matter (56%). Moisture stress-induced reductions in silk length (19%) and fresh weight (34%), negatively affected kernel number (53%), and weight (54%). Unlike …

Soil Health As Influenced By The Integration Of Cover Crops And Poultry Litter In North-Central Mississippi, Nikitha Reddy Kovvuri
Theses and Dissertations
Soil health-based agricultural management practices are widely promoted to improve soil structure, infiltration and reduce erosion. This study was conducted at two locations in North-Central Mississippi to evaluate the influence of different cover crop species and poultry litter on soil health that can impact crop production, climate change, and resilience. The results indicated that the cover crops showed a little effect on some soil health indicators compared to control treatment. However, in one location, rye, and a mixture of cover crops decreased bulk density and increased available water content and organic matter. The poultry litter had a positive effect on …

Integrity Of Indigenous Knowledge Systems In Natural Resource Management: The Case Of The Arid And Semi-Arid Baringo Herders Of Kenya, P. M. Makenzi, Abdillahi A. Aboud
IGC Proceedings (1977-2023)
Ineffective management of natural resources in arid and semi-arid lands (ASALs), resulting in resource depletion, rapid loss of biodiversity and environmental degradation, is of great concern globally. The Baringo herders in the ASALs of Kenya have been branded as perpetrators of this vice, with the blame placed particularly on their traditional livestock management, utilising indigenous knowledge systems (IKS). These IKS involve livestock mobility and maximisation, and have been regarded as being outdated and inefficient in meeting the challenges and demands for environmental conservation and sustainable management of the natural resources. A common reaction of the government has been to advocate …

The Role Of The Phare Programme And The Danish-Lithuanian Project On The Development Of The Grassland Production And Of Dairy-Beef Cattle Husbandry, V. Vrotniakiene, Jonas Jatkauskas
IGC Proceedings (1977-2023)
Animal production is one of the priorities for economic development in Lithuania. Dairy-beef cattle husbandry has remained an important branch of animal production under the conditions of agricultural reform. Favorable agroclimatic conditions for grass cultivation, old traditions of agricultural production and the ability to train farmers in new techniques creates good conditions for the development of dairy-beef cattle husbandry. It is most appropriate to use cattle types suitable for grass feeding with low inputs of concentrates. This paper reports on two development projects that sought to increase animal production through grassland improvement and the production of high-quality silage.

IGC Proceedings (1977-2023)
The use of irrigation systems is expanding in Egypt to facilitate cultivation on sandy areas that were previously desert. Many of the farmers starting on the new areas are undergraduates and others with no background in farming. Much support is required when they start farming. In addition, farmers moving to the new lands from the Nile Delta meet completely new challenges because the poor and infertile sandy soils require different management from the clay soils at the Delta. Ismailia Agricultural Research Station (IARS) of the Agricultural Research Center of Egypt focuses on research on how to cultivate the newly reclaimed …

Forage Development In The Nepal Mid-Hills: New Perspectives, A. D. Robertson
IGC Proceedings (1977-2023)
Nepali hill farming communities are typically poor and remote, and are currently severely affected by conflict. The challenge is to define simple approaches which can generate results within this context. Livestock are central to livelihoods and to the sustainability of farming, with rain-fed agriculture dependent on inputs of manure-based compost. Stall feeding has increased dramatically with the adoption of community forestry and general preclusion of grazing. A broad landscape approach to forage development is increasingly being adopted, with concurrent on-farm interventions, such as intercropping and back-yard forage, and off-farm interventions, such as landslide stabilisation with forages, development of forest understory, …

Factors Influencing The Adoption Of Fodder Production Techniques By Milk Producers In Dhankuta District, Eastern Nepal, C. P. Ferris, R. Nelson
IGC Proceedings (1977-2023)
Many districts are food-deficient in Nepal. Increased milk consumption could improve human health and nutrition, while milk sales can provide families with a valuable source of income. However, milk production in Nepal is low, mainly because of the poor nutritional status of livestock, which can be attributed in part to a fodder deficit. However there is potential to increase fodder production, and some innovative fodder production techniques have been tried and proven locally. These include planting of fodder trees, fodder grasses and fodder crops. As the level of adoption of these techniques is variable, a survey was undertaken to quantify …

The United States Dept. of Agriculture's Conservation Reserve Program (CRP) is a voluntary program available to agricultural producers who will enroll erosive, marginally productive cropland for a 10 to 15 year period. In return, participants are provided annual rental payments and cost-share assistance to establish and maintain long- term, resource-conserving vegetative cover to improve the quality of water, control soil erosion, and enhance wildlife habitat. Since the inception of the CRP, policymakers, conservationists, farmers, and rural residents have been concerned about the likely fate of program land after the contracts expire. Most of the existing research, whether it relies on …

Sustaining Grass-Legume Pastures For Cow-Calf Herds: A Case Study, John L. Caddel, D. D. Redfearn, R. L. Woods
IGC Proceedings (1977-2023)
An on-going pasture demonstration study has been used since 1988 to demonstrate methods to improve pasture production for small beef cow-calf herds. Many cattle enterprises are not economically viable because poor management decisions lead to excessive stocking rate, ineffective fertilisation programmes etc., leading to a dependence on hay purchases. The initial objective, continued until 2001, was to maintain one cow- calf pair per ha without purchasing forage or grain produced off farm. More recently, reducing the dependence on harvested forage has been added as an objective.
