Cover Crops Alternatives For Sustainable Agriculture Systems In Uruguay, Walter Ayala, José A. Terra, Ethel Barrios, Ignacio Macedo

IGC Proceedings (1977-2023)

In Uruguay, the increase of cropland area during the last decade was based on rotation systems intensification and soybean expansion, achieving 1.321.000 ha (Souto, 2014). Diaz (2007) demonstrated the value of the ley-farming systems where the integration of livestock and crop production achieved benefits on sustainability. Despite the advantages of crop-pasture rotation systems (García Prechac et al., 2004), grain market prices and food demand resulted in pasture phase losses in rotation with crops. Recently, Livestock Agriculture and Fisheries Ministry implemented a national soil conservation plan, that regulates cropping rotation systems based on soil erosion estimations and other key soil …

Application Of Payment For Ecosystem Services In China’S Rangeland Conservation: A Social-Ecological System Resilience Perspective, Wenjun Li, Yanbo Li

IGC Proceedings (1977-2023)

Payment for ecosystem services (PES) has been adopted by the Chinese government over the past decade as a mechanism to combat regional-scale rangeland degradation. We analyzed some fundamental problems associated with PES application in rangeland management from the perspective of social-ecological system (SES) resilience by using as a case study he PES project of “retire livestock to restore rangeland” in Inner Mongolia. The study findings demonstrated that PES project resulted in obvious negative impacts on local pastoralists’ livelihood and society networks without achieving any substantial rangeland restoration. Such failures are rooted in that PES strategy in which the logic of …

Variance Heterogeneity Genome-Wide Mapping For Cadmium In Bread Wheat Reveals Novel Genomic Loci And Epistatic Interactions, Waseem Hussain, Malachy T. Campbell, Diego Jarquin, Harkamal Walia, Gota Morota

Department of Agronomy and Horticulture: Faculty Publications

Genome-wide association mapping identifies quantitative trait loci (QTL) that influence the mean differences between the marker genotypes for a given trait. While most loci influence the mean value of a trait, certain loci, known as variance heterogeneity QTL (vQTL) determine the variability of the trait instead of the mean trait value (mQTL). In the present study, we performed a variance heterogeneity genome-wide association study (vGWAS) for grain cadmium (Cd) concentration in bread wheat. We used double generalized linear model and hierarchical generalized linear model to identify vQTL associated with grain Cd. We identified novel vQTL regions on chromosomes 2A and …

IGC Proceedings (1977-2023)

In Mediterranean regions, the development of a bioenergy sector is restricted by the scarce availability of species and varieties suitable to cultivation in rainfed environments, where summer drought affects plant survival (Scordia et al., 2014). Native perennial grasses that survive summer drought in a dormant or semi-dormant state may represent potential bioenergy crops. Nevertheless, the native germplasm of Mediterranean perennial grasses is unexplored for bioenergy production, except for giant reed, and little investigated also for other uses, as forage production. Smilo grass (Piptatherum miliaceum (L.) Coss) is a native species growing in marginal environments and it is palatable …

IGC Proceedings (1977-2023)

In arid eco-region of Rajasthan, India, common pool resources (CPRs) like common pastures and village water bodies provide ecosystem services such as fodder, fuel, timber, water and medicinal plants which are crucial for the livelihoods in particular of the poor. In western Rajasthan livestock keeping is the most important and resilient component of the agricultural systems which strongly depends on common pastures. However, the grazing areas have become severely degraded making the rural poor more vulnerable. A number of efforts have been made to improve the management of and rehabilitate the community pastures (Conroy and Lobo, 2002). The success of …

Valuation Of Forage Production Function Of Rangeland Ecosystems In North Of Iran–East Alborz Mountains, Shafagh Rastgar, Seyed Mojtaba Mojaverian

IGC Proceedings (1977-2023)

Rangeland ecosystem has 11-17 goods and services that most of them are public and non‐market in nature; meaning they are non‐rival and non‐exclusive and are typically not sold in a traditional; such as climate regulation, soil conservation, biodiversity, etc. (Croitoru, 2007; Wu et al., 2010). Forage is the main product of rangelands. According to the heterogeneity of range forages in terms of economic and lacking organized market for transaction, despite of imagine of ecological economists, it's a public good. So, determining its economic value as one of the main important nonmonetary functions of rangelands ecosystems can help managers to …

Operator Bias And The Effect Of Training On Visual Assessments Of Pasture Yield For Forage Budgets In Northern Australian Savanna, Nicole B. Spiegel, Peter O'Reagin, Angela Anderson, Megan R. Willis

IGC Proceedings (1977-2023)

Sustainable management of Australia’s extensive northern grazing lands is challenging given its highly variable interannual rainfall and pasture production. Accordingly, a key management recommendation is to adjust stocking rates to match forage supply (O’Reagain et al., 2014). ‘Stocktake’ is a forage budgeting system (Aisthorpe et al., 2004) widely used and promoted to assist graziers make short-term (< 1 year) adjustments of stocking rate. Budgets are typically calculated at the start of the dry season, to ensure sufficient forage for stock and ground cover levels until the first rains some six to nine months later. The software application ‘Future Beef Stocktake Plus’ has also been developed for use on smart devices (http://www.stocktakeplus.com.au/).

A key requirement for forage budgets is an accurate estimate of pasture mass. This is typically done visually with the aid of photo standards of pasture mass, providing a simple, efficient and non-destructive approach. Other key variables of forage budgeting include …

Economics Of Bn Hybrid Grass Production Bundelkhand Region Of India: A Case Study, Satendra Kumar, Ravi Pratap Singh, Rajiv K. Agrawal, J. B. Singh, M. M. Das, Sunil Kumar

IGC Proceedings (1977-2023)

Napier grass is also called as Elephant Grass due to its tallness and vigorous vegetative growth. The plants tiller freely and a single clump may produce more than 60 tillers under favorable climatic and soil conditions. Unfortunately, the grass coarse-textured, the leaf blade sheaths as well as sharply serrated, leaf margins. Therefore, cross was made between Bajra which is more succulent, leafy, fine-textured, palatable, fast growing and drought resistant and Napier to combine these qualities with its high yielding potential. The outcome Hybrid Napier is a perennial grass which can be retained on field for 2-3 years. Hybrid napier grass …

Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson

IGC Proceedings (1977-2023)

Beef cattle grazing (~14 million head) native pastures is the dominant economic use of northern grazing lands (2.3 million km2). Few enterprises make positive economic returns in most years or achieve the necessary productivity gains (~2% per annum) to offset an ongoing cost-price squeeze (McCosker et al., 2010). A significant contributor to poor performance is low reproductive performance, management of first calving heifers, calf growth and weaning rates and liveweight gain - linked to nutrition and the low quality of pastures. Pasture development technologies (Gramshaw and Walker, 1988) are available but uptake has been poor. Three pasture development options …

IGC Proceedings (1977-2023)

Biomass supply for different uses, especially for bioenergy production, is becoming increasingly important. Independently of the purposes of biomass use, high yields per unit area and best possible quality need to be achieved. As a result, the selection of appropriate plant species is an important aspect. Cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and reed canary grass (Phalaris arundinacea L.) were investigated on a light loam (Cambisol) with a view to assessing the impact of nitrogen (N) and harvest time on biomass yield used for biogas. The biomass yield was influenced by cutting …

Fairness And Efficiency: A Challenge For Payment For Environmental Services In Asia, Beria Leimona

IGC Proceedings (1977-2023)

Payment for environmental service (PES) is commonly defined as a market-based environmental policy instrument to efficiently achieve environmental protection. However, an increasing body of literature shows that the prescriptive conceptualization of PES cannot be easily generalized and implemented in practice and the commoditization of ecosystem services is problematic and may be unfair. To investigate the underlying causes, this study combined a quantitative and qualitative research approach using case studies in Indonesia, the Philippines and Nepal. The empirical observations on emerging PES-mechanisms in the Asian case studies show that interdependency of fairness and efficiency should be the main consideration in designing …

Identifying Priority Areas For Ecosystem Services Management In South Africa, Benis Egoh, Belinda Reyers, Mathieu Rouget, Patrick O’Farrel, David Le Maitre, Richard Cowling

IGC Proceedings (1977-2023)

Studies have highlighted the importance of managing ecosystem services to stop further degradation and transformation, yet very few studies have endeavored to identify priorities. The identification of priority areas for ecosystem services remains the least of objective for all studies that have mapped ecosystem services. Steps for identifying priority areas for management of ecosystem services include identifying features that supply ecosystem services, threats to service provision, potential actions to ensure future supply of service and cost of these actions as well as the availability of alternative means of providing benefits supplied by the service, the capacity to meet human demands …
