Working With Farmers: The Key To Adoption Of Improved Fodder Technologies, Satyapriya, P. Singh, H. V. Singh, P. Sharma

IGC Proceedings (1977-2023)

The lack of a close working relationship between agricultural research organizations, different extension organizations and with different categories of farmers is one of the most difficult institutional problems of agricultural technological implementation in India. Agricultural research and extension organizations generally fight over the same limited government resources and they try to increase the flow of resources coming to their respective institutions to solve day-today management problems, rather than ensuring that their respective organizations contribute to the broader goal of getting improved agricultural technology to all major categories of farmers. In addition, the researchers and extension workers of many research and …

Utilizing Grassland Resources For Sub-Arctic Agriculture: Sustainable Muskox Farming In Alaska, Laura Starr, Joshua Greenberg, Mingchu Zhang, Steven Seefeldt, Janice Rowell

IGC Proceedings (1977-2023)

The 2005 Millennium Ecosystem Assessment broadly classifies Alaska as a Polar Ecosystem, characterized as being frozen most of the year and underlain by permafrost. Despite this bleak portrayal, some of the largest herds of grazing ungulates are indigenous to Alaska - and thriving. This is both a testament to the resilience of grazing systems in general as well as a statement to the suitability of grazing systems specifically for Alaska. In a state economy dominated by nonrenewable resource extraction, agricultural production has remained largely undeveloped (Fried 2013). However, today there is increasing interest in local agricultural production with the goal …

Grasspea: A Potential Fodder And Feed Resources, Ashutosh Sarker, Pooja Sah, Vijay Kumar Yadav, M. M. Das

IGC Proceedings (1977-2023)

Grasspea (Lathyrus sativus L.) is a an important legume crop grown in India, Bangladesh, China, Ethiopia, Nepal, and Pakistan for human food, animal feed and soil health improvement. In India, grasspea is grown in about 521,100 ha, mainly in Chhattisgarh, Bihar, Jharkhand, Maharashtra, Orissa, Assam, West Bengal, and eastern Uttar Pradesh. Grasspea cultivation is low-cost and easy. Inherently grasspea possesses resistance to drought, excess moisture, salinity, diseases, and insect pests. As grasspea has an ambivalent reputation due to ODAP content in its plant parts, efforts are on to develop low or ODAP-free grasspea varieties with high biomass for dual …

IGC Proceedings (1977-2023)

Dual-purpose cattle farms (DP) in México and in particular in the south west of the State of México are low input, based on tropical pastures under extensive management combined with fodder trees and shrubs that contributes to forage production during the dry season, where grasses are scarce. Farms land extension ranged from 30 to 300 hectares. The stoking rate is low with less than a cow per ha. There is only a perimetral fence, there is no pasture´s subdivision. Cows browse freely within the rangeland 24 h/d all year round. Cattle are predominantly Brow Swiss with small proportion of zebu …

Productive Longevity Of Fodder Galega-Grass Swards, Aleksandrs Adamovics, Olga Adamovica, Iveta Gutmane

IGC Proceedings (1977-2023)

Red clover, alfalfa and white clover are traditional forage crops in Latvia. In Latvian agricultural practice, fodder galega (Galega orientalis Lam.) is grown for a relatively short period. Recently introduced into Latvia, it is rousing evergrowing interest due to its persistency and high yielding ability. Experiments on fodder galega show that this longlived legume survives in pure stands for 25 and more years and provides annual DM yields from 9.56 to 11.0 t ha^-1 (Adamovics and Auzins, 2006; Slepetys, 2000; Slepetys and Adomovics, 2011). Pure fodder galega stands, compared to other legumes, are not thinning out during harvest …

Fodder Yield And Quality Of Egyptian Clover (Trifolium Alexandrinum L.), Annual Ryegrass (Lolium Multiflorum Lam.), And Barley (Hordeum Vulgare L.) Monocultures As Affected By Organic And Mineral Fertilization, Heba Sabry Attia Salama

IGC Proceedings (1977-2023)

Egyptian clover (Trifolium alexandrinum L.) is the most important forage legume crop in Egypt. Despite the fact that its yield and protein content are high, it is characterized by low dry matter content especially in the 1st cut, in addition to its limited energy supply, attributed to the low carbohydrate content. Therefore, there is a pressing need to introduce some promising winter annual forage grasses, like barley (Hordeum vulgare L.) and ryegrass (Lolium multiflorum L.), and investigate their performance under the Egyptian agricultural conditions. This would enhance the Egyptian animal production systems by providing a high-quality feed …

Diversifying Agricultural Practices To Meet Fodder Requirements In The Nw Himalayas Through Improved Land Use Systems, Anurag Raizada, Suresh Kumar

IGC Proceedings (1977-2023)

True grasslands formed as climatic climaxes in India are confined to the alpine regions (> 3000 m s l) in the Eastern and Western Himalayas and have been studied for their productivity (Joshi et al.,1988., Ram et al., 1989) and vegetation diversity (Raizada et al., 1998). Other grasslands as they exist are stable sub-climax formations formed as a result of forest degradation and the occurrence of secondary succession in almost all over the Himalayan region. The livelihoods of mountain dwellers is mainly dependent on traditional agriculture and livestock rearing. Animal husbandry is an inseparable component of hill …

Dairy Intensification And Grassland Access For Livestock: A Comparative Study Of India And Bangladesh, Braja Swain, Dhiraj Singh

IGC Proceedings (1977-2023)

Dairying is the next-best alternative for rural livelihood after crop in South Asia, where more than fifty percent of population depends on it. The milk production is concentrated in the rain-fed and irrigated crop-livestock systems of India, which contributes more than 90 percent of milk production in South Asia. Despite this vast expansion of milk production in India–dairying is characterized by a predominance of small-scale dairy producers who cultivates or have no land and reliance only on indigenous breeds of cattle and buffaloes, where grazing plays an important role for feed. However, dependency on indigenous cattle and grazing changes based …

The Effects Of Temperature On Evacuation Rates And Absorption Efficiency Of Flathead Catfish, Zach Horstman

School of Natural Resources: Dissertations, Theses, and Student Research

Knowledge of fish gastric evacuation rates are a necessary component for both field and laboratory studies when trying to understand feeding rates, modeling energy budgets, and understanding trophic dynamics of aquatic ecosystems. Many freshwater fish encounter a broad range of environmental temperatures across life history stages, but the mechanistic link between temperature and physiological processes often remains poorly understood. We designed three recirculating aquatic systems capable of rearing Flathead Catfish Plyodictis olivaris in order to quantify gastric evacuation rates and gross energy absorption at three temperatures (17º C, 22º C and 25º C). We examined the relationship between temperature and …

School of Natural Resources: Dissertations, Theses, and Student Research

Climate change is the paramount challenge of today for a sustainable future. Mitigation of greenhouse gas (GHG) emissions is necessary to reduce the associated risks and impacts on society. Using the EPA’s SIT and literature review, comprehensive GHG-emissions inventories were developed for the state of Nebraska over 25 years (1990-2015) and agricultural GHG emissions inventories were developed for the Midwest U.S for one year (2016). Nebraska’s net emissions increased from 56.2 million metric tons of carbon dioxide equivalent (MMtCO₂e) in 1990 to 87.4 MMtCO₂e in 2016. Agriculture was found to be the sector with the most …

In Hot Water: Influence Of Multiple Stressors On Thermal Tolerance Of Fathead Minnows Pimephales Promelas, Alexander Engel

School of Natural Resources: Dissertations, Theses, and Student Research

Freshwater aquatic systems around the globe are often subjected to physical, biological, and chemical alterations to support societal needs. The Great Plains contains one of the largest agricultural industries in North America, but its productivity has ecological repercussions for adjacent freshwater ecosystems. Specifically, the dependency on surface water irrigation and application of chemical treatments has altered the thermal and chemical composition of freshwater ecosystems throughout the region. Stressors such as elevated temperatures, altered flow regimes, increased contaminant loads affect the physiology and behavior of fishes and can lead to long-term population effects. We examined thermal tolerance of Fathead minnows Pimephales …

Sublethal Effects Of Sulfoxaflor Pesticide On Physiology And Behavior Of Daphnia Magna, Mary Hoffman

Research and Creativity Symposium

Insect pests are a major concern for large-scale agriculture as a result of increasing insect resistance to pesticides, driving a need for the development of new pesticides. Sulfoxaflor, a sulfoximine pesticide recently approved for use by the USEPA, was developed in order to replace neonicotinoid use and has shown to have high efficacy in the field. It is used in rotation with other pesticides, with environmental introduction caused primarily by wet spray application or agricultural runoff. In insects, sulfoxaflor binds to nicotinic acetylcholine receptors, triggering over-activation that leads to paralysis and death. Preliminary exposure studies have shown neonatal effects and …

Vegetation Dynamics In Relation To Land Use Within The High Altitude Alpine Grasslands Of Lesotho, Southern Africa, Nico Smit, G. Janse Van Rensburg

IGC Proceedings (1977-2023)

The Kingdom of Lesotho is characterized by its unique geographical feature of being dominated by rugged mountainous terrain. It is also the only true alpine region in southern Africa that supports high plant species diversity. Large areas suffer from overgrazing and erosion, as well as over exploitation of its natural resources. The livestock industry in Lesotho has long been a vital component of the economic and social structure of the country and the alpine region is considered as an important grazing resource by local Basotho herdsmen. Consequently, a study was conducted with the two objectives: to determine the phytomass, grazing …

Mountain Pasture Management By Goat Farmers: Case Of Kabylia Region, Mouhous, Kadi, Djellal, Berchiche

IGC Proceedings (1977-2023)

In mountainous areas of Algeria, like the countries of North Africa and the Sahel, small ruminants contribute substantially to the food and economic security of mountain households (Bengoumi and Ameziane El Hassani, 2013). Changes in the farming environment affected the small ruminant production systems. These changes induced adaptations related to conducting of breeding and production orientation (Dubeuf and Boyazoglu, 2009). In Tizi Ouzou in Kabylia region, dairy goat farming operates in an environment appropriate because of its relief and vegetation (presence of vegetation, forests,). The extensive farming system is the one used in the study area. The herds are of …

IGC Proceedings (1977-2023)

Ber is mainly cultivated for its fresh fruits, which are rich in vitamins C, A and B complex. Due to its nutritional qualities it is called poor man’s apple (Gajbhiya et al., 2003). A large number of wild ber shrubs (Zizyphus mauritiana, Z. rotundifolia and Z. nummularia) were seen growing on the neglected lands, uncultivated lands, roadsides and farm boundaries in Kadesara Kala Village in Lalitpur district of Uttar Pradesh (India). Production potential of this species is very low because of poor upkeep and inferior genetic makeup. But they have extensive root system which can withstand …

Does Producing Forages Improve Livelihoods In Dry Areas? The Case Of Afghanistan (On-Going Research), Roberto Tellaria, Serkan Ates, Srinivas Tavva, Hyatullah Esmati

IGC Proceedings (1977-2023)

Agriculture is the main livelihood and a major contributor to the Afghan economy. Livestock production contributes with almost 50% of agricultural GDP in Afghanistan where out of 75% Afghans who live in rural areas, 85% keep some livestock (AusAID and ACIAR, 2011). In particular, small ruminants (sheep and goats) provide small holder rural Afghan families with livelihoods, food and capital. However, insufficient feed is a key constraint that limits productivity, income growth and sustainability in the crop-livestock farming (GIRoA, 2009). The purpose of this research was to assess and identify which forage production technologies offers high productivity and resilience to …

Participatory Evaluation Of Herbage Composition, Biomass Yield, And Management Practices Of Natural Grazing Lands In Sidama Highlands Of Southern Ethiopia, Yoseph Mekasha, Birhanu Biazen, Azage Tegegne, Tesfaye Shewage

IGC Proceedings (1977-2023)

Natural grazing land is the dominant source of feed for ruminant livestock in Ethiopia (Alemayehu, 2003; Zewdie and Yoseph, 2014). However, the production capacity and quality of natural grazing lands has been deteriorating over time and could not support optimum livestock production. Overgrazing the natural grazing lands due to poor grazing land management is among the major contributing factors (Alemayehu, 2003). Although previous studies focused on the evaluation of native grass lands it was either limited to arid and semi-arid agro-ecology or undertaken under different settings (Ayana, 2010; Diriba et al., 2012). Moreover, it did not involve the community …

Archaeological Feature Identification Through Geochemical Analysis Of Arctic Sediments From The Cape Krusenstern National Monument, Northwest Alaska, Patrick William Reed

Dissertations and Theses

Identification and interpretation of archaeological phenomena is typically based on visual cues and the physical presence of "something archaeological," such as a diagnostic artifact, landscape modification, or structural element. Yet many archaeological features, i.e. the discrete archaeological deposits related to past human behavior, lack clear indicators of human activity that provides clues to the feature's origin. At the Cape Krusenstern beach ridge complex, located in northwest Alaska, ambiguous features, that could be natural or anthropogenic (vegetation anomalies), or are of unknown cultural function (indeterminate), comprise 60% of the identified features at the complex. These ambiguous features represent a large gap …

253— The Impact Of Physical And Chemical Weathering On Iron Slag From Standish, Ny, Maria Leonard

GREAT Day Posters

From 1883 to 1907, magnetite ore was smelted Standish, NY. During this time, a large amount of slag, a byproduct of smelting, was created. The slag is now in a pile that covers ~13 acres in the northeastern region of the Adirondacks. The impact of weathering is evident through a comparison of samples collected ~15 years ago to partner samples still out in the field which are more fractured and have calcitic weathering rinds. For more quantitative data, we carried out a field experiment and a leaching test. In the field experiment we exposed different slag samples (glassy, chalky, and …

Improvement Of Grazing Lands For Better Livestock Production--A Case Study From Chitradurga District In India, K. Girdhar, A. V. Elangovan, H. S. Shivaramu

IGC Proceedings (1977-2023)

Chitradurga is a highly drought prone district in the central dry zone of Karnataka, India, with a normal rainfall of 530 mm per annum. Over 85 per cent of cultivable area is rainfed and the livestock plays a vital role in rural income generation in this district. Improper management and overgrazing have resulted in most of the grazing resources declining to a poor, degraded condition. Regeneration of pasture land was vital in the villages due to three reasons - a) people's livelihood dependency on livestock was considerable b) small ruminants played a vital role for landless farmers and c) lack …

Mongolian Pastoralism–Nomadism And Marketing, Ralph Van Gelder, Nigel Brown, Dorlig Shombodon

IGC Proceedings (1977-2023)

Mongolian pastoralism is a treasured “art” and tradition, honoured for its resourcefulness and maintained by the national social and political environment, but in the modern world it is an anachronism. Modern market requirements, enforced by domestic and international consumers, are rendering current Mongolian pastoralism unsustainable. Traditional nomadic herding is a subsistence activity. The products of modern herders are traded in domestic and international markets, hence modern nomadic herding is a profit making activity, in which product specification to satisfy consumers has to be the driver for grazing management and pasture utilisation considerations.

Cultural Bastions, Farm Optimisation And Tribal Agriculture In Aotearoa (New Zealand), Tanira Kingi

IGC Proceedings (1977-2023)

This paper outlines the influence of cultural factors (including tradition knowledge systems) on tribal agricultural organisations in Aotearoa-New Zealand (NZ); and then presents a conceptual framework that integrates several existing models and tools designed specifically for Māori farmer collectives. Traditional knowledge systems have a pervasive influence on NZs Māori agribusiness sector. However, they often go unrecognised; concealed beneath a land tenure system and legislative framework that is restrictive, cumbersome and has been responsible for widespread land loss since its introduction almost 150 years ago. In spite of these constraints, Māori agriculture in NZ is vibrant, diverse and has several unique …

Application Of Pastoralists' Knowledge To Natural Resource Management In Spain, Elisa Oteros-Rozas, María Fernández-Giménez, Ricardo Ontillera-Sánchez, José A. González, Federico Fillat-Estaque

IGC Proceedings (1977-2023)

Extensive livestock rearing has been acknowledged as an important tool for sustainable management of social-ecological systems and biodiversity conservation. In the Mediterranean Basin this relationship has been highlighted in mountainous and rural areas, where the co-evolved assemblages and dynamics of plant communities and grazing practices and patterns are mutually reinforcing. Among extensive livestock rearing systems, mobile pastoralism is a typical adaptation in semi-arid areas and mountainous regions where pasture availability is especially variable in time and space. In Spain, mobile pastoralism dates back to Neolithic and has survived until our days in different ways. An outstanding example of mobility is …

Barriers And Opportunities For The Use Of Forage Tree Legumes In Smallholder Cattle Fattening Systems In Eastern Indonesia, Debora Kana Hau, Tanda Panjaitan, Jacob Nulik, H. Dahlanuddin, Elske Van De Fliert

IGC Proceedings (1977-2023)

Forage tree legumes (FTL) have existed in the Eastern Indonesian landscape since colonial traders introduced several species in the late 1800s. A specific effort was made to establish leucaena (Leucaena leucoephala) and sesbania (Sesbania grandiflora) for use as forage for cattle fattening at Amarasi in East Nusa Tenggara Province and Central Lombok in West Nusa Tenggara, in the 1970s (Yuksel et al. 1999; Dahlanuddin et al. 2005). Its spread within these provinces as potential forage to intensify cattle fattening systems, however, has been slow if not stagnant. In preparation for intensified efforts to encourage …

Allocating Rangelands To The Optimum Land Use By Applying A Decision Support System, Seyed Alireza Mousavi, Hossein Arzani, Mehdi Farahpour

IGC Proceedings (1977-2023)

Rangelands in Iran are faced with a considerable level of degradation and human interventions due to pressures for increased food production and the need to generate more benefits for an increasing population. A first step in solving this problem is to develop methodology to efficiently analyse the current situation and effectively reallocate rangelands into optimum land uses. To achieve an agreed solution for land allocation, an interactive approach is required to recognize and comprehensively assess different alternatives.

This paper suggests an introductory framework for developing a decision support system for allocation of rangeland areas into the most optimum use.
