A Binary Logit Analysis of Factors Impacting Adoption of Genetically Modified Cotton AgEcon
Banerjee, Swagata (Ban); Martin, Steven W..
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.

A Binary Logit Estimation of Factors Affecting Adoption of GPS Guidance Systems by Cotton Producers AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Roberts, Roland K.; Larkin, Sherry L.; Larson, James A.; Paxton, Kenneth W.; English, Burton C.; Marra, Michele C.; Reeves, Jeanne M..
Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

A Choice-Based Conjoint Experiment with Genetically Engineered Cotton in the Mississippi Delta AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Hudson, Darren.
Producers' preferences for cottonseed are examined using a willingness-to-pay (WTP) approach via mail surveys. Results indicate a positive WTP for yield, technology and fiber quality, and it increases with the level of technology and quality, respectively. WTP varies directly with farm size and inversely with farm labor.

Adoption and Abandonment of Precision Soil Sampling in Cotton Production AgEcon
Walton, Jonathan C.; Roberts, Roland K.; Lambert, Dayton M.; Larson, James A.; English, Burton C.; Larkin, Sherry L.; Martin, Steven W.; Marra, Michele C.; Paxton, Kenneth W.; Reeves, Jeanne M..
Technology adoption in precision agriculture has received considerable attention, while abandonment has received little. Our objective was to identify factors motivating adoption and abandonment of precision soil sampling in cotton. Results indicate younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, used a computer, or used a Personal Digital Assistant (PDA) were more likely to adopt precision soil sampling. Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, used a PDA, or used variable-rate fertilizer application were less likely to abandon.

Adoption of Site-Specific Information and Variable-Rate Technologies in Cotton Precision Farming AgEcon
Roberts, Roland K.; English, Burton C.; Larson, James A.; Cochran, Rebecca L.; Goodman, W. Robert; Larkin, Sherry L.; Marra, Michele C.; Martin, Steven W.; Shurley, W. Donald; Reeves, Jeanne M..
Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmer who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable-rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important, possibly because custom hiring shifts the burden of computer use to agribusiness firms.

ALTERNATIVE COTTON PRODUCTION SYSTEMS AgEcon
Parvin, David W., Jr.; Cooke, Fred T., Jr.; Martin, Steven W..
Mississippi cotton farmers are adjusting to the current problem of low cotton price and high cotton production cost by modifying the way(s) they have traditionally grown cotton. This paper compares seven alternative production systems to the costs and returns associated with the conventional or traditional system labeled "solid cotton, 8-row equipment." Systems that combine wider equipment (less labor and machinery time per acre) with reduced tillage technology appear to offer opportunities to increase returns. Specific adjustments on individual farms will probably be dominated by the distribution of soil types.

DEVELOPING AND PRICING PRECIPITATION INSURANCE AgEcon
Martin, Steven W.; Barnett, Barry J.; Coble, Keith H..
Production agriculture and agribusiness are exposed to many weather-related risks. Recent years have seen the emergence of an increased interest in weather-based derivatives as mechanisms for sharing risks due to weather phenomena. In this study, a unique precipitation derivative is proposed that allows the purchaser to specify the parameters of the idemnity function. Pricing methods are presented in the context of a cotton harvest example from Mississippi. Our findings show a potential for weather derivatives to serve niche markets within U.S. agriculture.

Effects of Seed and Farm Characteristics on Cottonseed Choice: A Choice-Based Conjoint Experiment in the Mississippi Delta AgEcon
Banerjee, Swagata (Ban); Hudson, Darren; Martin, Steven W..
Producers’ preferences for cottonseed with respect to price, seed type, yield, and fiber quality are examined by a willingness-to-pay approach via mail surveys. Results indicate a positive willingness to pay (WTP) for technology relative to conventional cottonseed, and WTP increases with the level of technology. Yield and quality also show a positive WTP. Larger farms have a higher WTP for technology, and farms with more farm labor have a lower WTP for technology. These results suggest economies of size in technology adoption (biotechnology is not size-neutral) and that labor and biotechnology are direct substitutes.

EXTENSION EDUCATORS' SUPPLY OF RISK MANAGEMENT TRAINING TO FARMERS AgEcon
Vergara, Oscar; Martin, Steven W.; Coble, Keith H.; Knight, Thomas O.; Patrick, George F.; Baquet, Alan E..
A univariate Tobit model of extension educators' provision of risk management educational training was conducted in Mississippi, Texas, Indiana, and Nebraska. A complementary relationship exists between percent of time devoted to agricultural responsibilities and the provision of risk management training courses. The results indicate that, as extension educators perceive farmers to be more knowledgeable of risk management tools, their provision of risk management education decreases. On the other hand, the provision of risk management courses increase as extension educators perceive themselves as being more knowledgeable on the use of risk management tools.

Factors Affecting Perceived Improvements in Environmental Quality from Precision Farming AgEcon
Larkin, Sherry L.; Perruso, Larry; Marra, Michele C.; Roberts, Roland K.; English, Burton C.; Larson, James A.; Cochran, Rebecca L.; Martin, Steven W..
This study identified the factors that influenced whether farmers in the Southeastern United States perceived an improvement in environmental quality from adopting precision farming technologies (PFTs). Farmers with larger farms or higher yields were more likely to believe that they observed positive externalities associated with PFTs. Farmers who found PFTs profitable or who believed input reduction was important had higher probabilities whereas those with higher incomes or who were more dependent on farm income were less likely to perceive such benefits. Interestingly, the importance of environmental quality and length of time using PFTs were not found to affect the probability of perceiving an improvement in environmental quality.

Factors Influencing Farmer Adoption of Portable Computers for Site-Specific Management: A Case Study for Cotton Production AgEcon
Walton, Jonathan C.; Larson, James A.; Roberts, Roland K.; Lambert, Dayton M.; English, Burton C.; Larkin, Sherry L.; Marra, Michele C.; Martin, Steven W.; Paxton, Kenneth W.; Reeves, Jeanne M..
Personal digital assistants (PDA) and handheld global positioning systems (GPS) have become increasingly important in cotton production but little is known about their use. This research analyzed the adoption of PDA/handheld GPS devices in cotton production. A younger farmer who used a computer in farm management and had a positive perception of Extension had a greater likelihood of adopting the devices. In addition, farmers who used complementary remote sensing, plant mapping, and grid soil sampling information were more likely to use PDA/handheld GPS devices. Finally, the COTMAN in-field decision support program from Extension also positively impacted adoption.

Factors Influencing the Selection of Precision Farming Information Sources by Cotton Producers AgEcon
Jenkins, Amanda; Velandia, Margarita M.; Lambert, Dayton M.; Roberts, Roland K.; Larson, James A.; English, Burton C.; Martin, Steven W..
Precision farming information demanded by cotton producers is provided by various suppliers, including consultants, farm input dealerships, University Extension systems, and media sources. Factors associated with the decisions to select among information sources to search for precision farming information are analyzed using a multivariate probit regression accounting for correlation among the different selection decisions. Factors influencing these decisions are age, education, and income. These findings should be valuable to precision farming information providers who may be able to better meet their target clientele needs.
