Changing Produce Marketing Barriers: A Comparison Among Three Southern States AgEcon
Eastwood, David B.; Brooker, John R.; Hall, Charles R.; Rhea, Alice J.; Estes, Edmund A.; Woods, Timothy A..
Produce growers in Kentucky, North Carolina, and Tennessee were surveyed in 2002 to gather information about their decision making in the areas of planting, postharvest handling, marketing, and expected changes. North Carolina has proportionately more respondents with large operations, and Kentucky and Tennessee were more similar and concentrated in smaller farms. Tennessee and Kentucky respondents were less likely to have engaged in activities that were associated with the commercial distribution system. Greater reliance on the commercial distribution system on the part of North Carolina growers is consistent with more produce export activity.

The Economics of Rotational Grazing in the Gulf Coast Region: Costs, Returns, and Labor Considerations, Phase II AgEcon
Gillespie, Jeffrey M.; Wyatt, Wayne; Venuto, Brad; Blouin, David; Boucher, Robert W.; Nipper, Weldon; Qushim, Berdikul.
Profitability and labor associated with rotational grazing at three stocking rates and continuous grazing at a medium stocking rate are compared. On a per-acre basis, profits are lowest for low stocking rate rotational grazing. Labor is greatest on both per-acre and per-cow bases with high stocking rate rotational grazing.

Demographic Factors Affecting the Adoption of Multiple Value-Added Practices by Oklahoma Cow-Calf Producers AgEcon
Williams, Brian R.; Raper, Kellie Curry; DeVuyst, Eric A.; Peel, Derrell S.; Lalman, David L.; Richards, Chris; Doye, Damona G..
The utilization of marketing programs to enhance feeder calf value has been met with modest success in Oklahoma. Value-added programs are continually promoted as avenues for improving cow-calf profitability, but producer adoption of value-added practices lags in spite of research showing the value of these practices. Identifying producer characteristics that increase their likelihood to adopt value-added practices is critical to developing successful outreach efforts. Results from a survey of Oklahoma producers on value-added practice adoption indicate that multiple demographic variables influence a producer’s likelihood of practice adoption. For Extension specialists, results can help in targeting likely adopters and developing methods to overcome...

The Effect of Risk, Ambiguity and Coordination on Farmers’ Adaptation to Climate Change: A Framed Field Experiment AgEcon
Alpizar, Francisco; Carlsson, Fredrik; Naranjo, Maria.
The risk of losses of income and productive means due to adverse weather associated to climate change can significantly differ between farmers sharing a productive landscape. It is important to learn more about how farmers react to different levels of risk, under measurable and unmeasurable uncertainty. Moreover, the costs associated to investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore these issues using a framed field experiment that captures realistically the main characteristics of production, and the likely weather related losses of premium coffee farmers in Tarrazu, Costa Rica. Given that the region recently was severely hit by an extreme, albeit very infrequent, climatic event, we expected to...

Technology Adoption And Pest Control Strategies Among UK Cereal Farmers: Evidence from Parametric and Nonparametric Count Data Models AgEcon
Sharma, Abhijit; Bailey, Alastair; Fraser, Iain.
This paper examines technology adoption and integrated pest management strategies employed by UK farmers, using both parametric and nonparametric methods. We employ a unique survey data set collected from UK cereal farmers to assess the determinants of technology adoption in relation to pest management. Our preferred model specification is nonparametric which makes use of the recently developed methods of Li and Racine (2007) and Racine and Li (2004). These methods allow us to combine categorical and continuous data and thereby avoid sample splitting and resulting efficiency losses. Our analysis reveals that total area farmed is positively related to the number of technologies adopted, whereas age is negatively related. We also find evidence of...

The U.S. Patent System and Developing Country Access to Biotechnology: Does the Balance Need Adjusting? AgEcon
Taylor, Michael R.; Cayford, Jerry.
Many agricultural and food security experts believe that biotechnology has potential to assist developing country farmers in meeting current and future food needs. Most of the tools of biotechnology have been developed, however, by companies, governments, and universities in industrialized nations; are the subject of U.S. patents; and have so far been applied commercially to address the needs of large-scale growers in the United States and other developed countries. For commercial and other reasons, applications of biotechnology that might benefit developing country farmers are unlikely in the foreseeable future to be developed and disseminated through commercial channels. At the same time, noncommercial, public sector researchers report that their access...

A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture AgEcon
Langyintuo, Augustine S.; Hamazakaza, Petan; Nawale, Edah; Mekuria, Mulugetta.
This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated non-separable household demand and consumption models using data collected from 300 farm households in Zambia during the 2003/04 crop season. The estimated results...

Intellectual Property Rights and Their Impacts in Developing Countries: An Empirical Analysis of Maize Breeding in Mexico AgEcon
Leger, Andreanne.
There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry. The analysis of the interviews with maize breeders leads to the conclusion that the theory on IPR should be revised and take into account the characteristics of developing countries critical for the...

Technology Adoption Against Invasive Species AgEcon
Ranjan, Ram.
This article looks at technology adoption in agriculture that is specifically targeted against invasive species. The analysis involves predicting the long-term distribution of technology choices when technology can be adopted and is adopted based on current and expected agricultural profits influenced by pest infestation. The theoretical analysis is based on an extension of two authors’ findings in 1993 and incorporates the possibility that psychological factors, such as complacency, have a significant impact on technology adoption and hence disease establishment. An empirical application is performed for soybean rust.

The impact of Access to Credit and Training on Technological Adoption: A Case of the Rice Sector in Tanzania AgEcon
Nakano, Yuko; Kajisa, Kei.
Using an extensive household-level data set collected in Tanzania, this paper investigates the determinants of the technological adoption of rice cultivation and of paddy yield. We especially focus on the impact of credit and training on the adoption of modern technologies. Based on empirical results, we argue that modern inputs and improved practices of rice cultivation enhance the increase in paddy yield. We also argue that the impact of credit and training on the adoption of modern technologies can differ for different technologies. If the adoption of a specific technology does not require a large amount of cash, knowledge given by training is sufficient to enhance adoption. On the other hand, those who can access credit or self-finance can adopt...

Staying in Touch through Extension: An Analysis of Farmers’ Use of Alternative Extension Information Products AgEcon
Jones, Lauren E.; Diekmann, Florian; Batte, Marvin T..
The U.S. farming industry is evolving quickly. It is therefore important that state Extension services be prepared to evolve as well. This study uses data collected in a 2007 survey of Ohio farmers to evaluate likelihood and frequency of use of various services offered by Extension as well as overall satisfaction with Extension services. Results indicate that tailoring of topics and communication methods to type of farm and/or farmer informational needs could improve the use of Extension resources. This implies that targeting of information products and methods may improve the performance of Extension education programs and customer satisfaction.

Awareness of and Application to the Environmental Quality Incentives Program By Cow–Calf Producers AgEcon
Obubuafo, Joyce; Gillespie, Jeffrey M.; Paudel, Krishna P.; Kim, Seon-Ae.
This study uses a bivariate probit model with partial observability to examine Louisiana beef producers’ awareness of the Environmental Quality Incentives Program (EQIP) and how awareness translates to application to the program. Results indicate that awareness of and application to the EQIP depend on portion of income derived from off-farm sources, extent of previous best management practice adoption at one’s own expense, household income, farmed land that is highly erodible, contact with Natural Resource Conservation Service and extension service personnel, and producer age.

Estimation of Efficiency, Sustainability and Constraints in SRI (System of Rice Intensification) vis-a-vis Traditional Methods of Paddy Cultivation in North Coastal Zone of Andhra Pradesh AgEcon
Rao, I.V.Y. Rama.
The study has assessed the economics and sustainability of SRI (system of rice intensification) and traditional methods of paddy cultivation in North Coastal Zone of Andhra Pradesh for the period 2008-09, based on the data of costs and returns of crop. Apart from budgeting techniques, benefit-cost ratio (BCR), yield gap analysis, sustainability index and response priority index have been employed in the study. It has shown that BCR is higher for SRI (1.76) than traditional (1.25) methods. Further, there is a 31 per cent yield gap between SRI and traditional methods, in which cultural practices (20.15%) have shown a stronger effect than input use (10.85%). The most important constraint in SRI cultivation has been identified as ‘nursery management’. The SRI...

FARM CERTIFICATION AND THE IMPLEMENTATION OF HACCP IN AGRICULTURE: A COST/BENEFIT ANALYSIS AgEcon
Galan, Mari-Neatrice; Aubry, Christine; Maze, Armelle.
This article aims to highlight the methodological bases and principles, sometimes implicit, that have served as support for the development of a referential similar to the one retained as part of the French decree on "Agriculture Raisonnée", namely the Quali'Terre referential. We show that the innovations introduced by this referential are of various natures: i) a change of perspective by taking a position at the level of the farming system and not of a given parcel of land or production, ii) use of the HACCP method for identification and most especially the prioritization of risks and the preventive measures to be implemented, iii) the introduction of the concept of continual improvement for the farmer. Even, if from an agronomic point of view, the...

Private Research and Public Goods: Implications of Biotechnology for Biodiversity AgEcon
Raney, Terri; Pingali, Prabhu L..
The pattern of crop genetic diversity has changed over the past two centuries with the modernization of agriculture, accelerating with the advent of the green revolution. Since the green revolution, the locus of agricultural research has shifted from the public to the private sector. The growing importance of the private sector in agricultural R&D is changing the types of crop technologies that are developed and the ways they are delivered to farmers. The spread of transgenic crops will influence crop genetic diversity, but their implications for the availability of plant genetic resources and the resilience of agricultural ecosystems are not entirely clear. Transgenic crops may increase or decrease crop genetic diversity, depending on how they are...

Which parameters determine farm development in Germany? AgEcon
Roder, Norbert; Kilian, Stefan.
In 2005, Germany implemented the Single Payment Scheme which lead to the conversion of direct payments into tradable, production decoupled, single farm payments. The transition from coupled to decoupled support instruments may impact the rate of structural change. The rate of structural change may accelerate since farms with a high share of income derived from CAP payments will abandon farming and lease their land. However, there are also good reasons why the rate of structural change might decrease especially if farmers do not behave as profit maximizers. In Germany agricultural land use is very heterogeneous with respect to management orientation and productivity even at local level. Most of the concerns related to structural change and development of...

The 'Landcare' Approach to Soil Conservation in the Philippines: An Assessment of Farm-Level Impacts AgEcon
Cramb, Rob A.; Catacutan, Delia; Culasero-Arellano, Z.; Mariano, K..
"Landcare" is a group-based approach to the promotion of conservation farming. A case study of the Landcare program in Lantapan in the southern Philippines is presented to assess the farm-level impacts of this approach. The program was successful in promoting the formation of Landcare groups and a municipal Landcare association, resulting in rapid and widespread adoption of conservation practices, particularly among maize farmers. This in turn significantly reduced soil erosion, though the impact on crop yield and income was somewhat delayed. Adoption was thus not motivated primarily by short-term returns but by a concern to reduce soil erosion and provide a basis for diversification into agroforestry.

Atributos de confianza, normas y certificacion. Comparacion de estandares para hortalizas AgEcon
Compes, Raul.
RESUMEN: Cuando un producto tiene atributos de confianza que son valorados por los consumidores, el mercado no funciona de forma óptima. Si existen externalidades negativas derivadas del consumo y la producción es eficiente que el gobierno establezca normas sobre las características del producto, del proceso productivo, del etiquetado o de las responsabilidades del productor. Si existen externalidades positivas o la acción colectiva es costosa lo óptimo puede ser que el gobierno fije o promueva estándares voluntarios. En el resto de los casos, es posible que una empresa transmita información creíble a los consumidores a partir de un sistema de aseguramiento privado mediante el cuál una entidad independiente certifique que cumple unos determinados...
