Growing Lavender In Western Australia, Aileen Reid Aug 2000

Growing Lavender In Western Australia, Aileen Reid

Bulletins 4000 -

Lavender oil is an essential oil, derived from plants (genus Lavendulai primarily by steam distillation of the flowers. There are several types of lavender oil. The 'true' lavender oil, and the most highly prized, comes from Lavendula augustifolia; it is primarily used in the fragrance and perfume industry. World production is about 200 tonnes per year. Spike lavender oil, derived from Lavendula latifolia, has a world production of about 150-200 tonnes per year. Lavandin oil is derived from hybrids of L. augustifolia x L. latifolia that yield much higher than L. augustifolia but the oil is lower quality, hence it ...

Leopold Center Completed Grant Reports

What is the potential payoff for farmers moving from traditional whole-field management or integrated crop management to precision farming? Using computer models, the investigators sought to analyze how inputs can be applied at optimal rates variably across a field in order to match inputs with crop needs. Over the long term, only modest increases were shown in gross returns from these practices. However, gross returns for individual years can be substantial.


Market Potential For Pork Products With Embedded Environmental Attributes: An Experimental Approach , Sean Patrick Hurley Jan 2000

Market Potential For Pork Products With Embedded Environmental Attributes: An Experimental Approach , Sean Patrick Hurley

Retrospective Theses and Dissertations

This dissertation focuses on determining benefits or value of environmental improvements in agricultural production, specifically, with an application to the pork industry. Values or benefits from reduced odor, reduced manure run-off, and reduced manure spills were elicited from consumers from Iowa, Kansas, Vermont, Oregon, and North Carolina. For the study, two pound packages of pork chops with selected combinations of air, ground water, and surface water environmental attributes were used to obtain consumer willingness-to-pay for environmental improvements. These benefits or willingness-to-pay for improved environmental practices have been obtained through research using a multiple trial second-price sealed-bid auction;A focus of ...


Economic Issues In Resistance Management , Silvia Secchi Jan 2000

Economic Issues In Resistance Management , Silvia Secchi

Retrospective Theses and Dissertations

This dissertation analyzes economic issues related to the use of agricultural pesticides and antibiotics. The efficacy of both these chemical compounds depends on the existence of susceptible targets. However, through natural selection, their utilization increases the frequency of the genes resistant to the pesticide or drug in the target population, and it decreases the available biological capital of genetic susceptibility, increasing resistance;The aim of this dissertation is to analyze the characteristics of optimal resistance management strategies. An empirical analysis is offered in case of bioengineered Bt corn, which underlines the importance of pest mobility, and the externalities it causes ...


Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen Jan 2000

Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen

Retrospective Theses and Dissertations

Changes in Mexico's domestic agricultural policy (PROCAMPO) and continued liberalization of trade through GATT and NAFTA have had strong effects on Mexico's agricultural production, consumption, and trade with the United States. The main objective of this study is to analyze these effects in Mexico's grain and livestock sectors. Policies within the NAFTA and GATT international trade agreements may overlap to some degree, and Mexico's domestic agricultural liberalization program (PROCAMPO) may include policies that overlap those in one or both of the international trade agreements. This study analyzes the effects of PROCAMPO, NAFTA, and pre-GATT policies compared ...


Value-Adding Partnerships In Proprietary Value-Enhanced Specialty Grain: A Case Study Of High Oil Corn , Wenying Du Jan 2000

Value-Adding Partnerships In Proprietary Value-Enhanced Specialty Grain: A Case Study Of High Oil Corn , Wenying Du

Retrospective Theses and Dissertations

This dissertation examines the value-adding partnerships in commercializing a proprietary value-enhanced specialty grain---DuPont's High Oil Corn, analyzes the decision-makings along the value chain, and explains the governance structure of the value-adding partnership from the perspective of the theory of firm. It argues that private investment efforts play an important role in determining the governance structure, and the governance structure evolves with the evolution of the importance of those efforts.


Estimation And Attenuation Of Reinsurance Risk In The Crop Insurance Market , Charles Edwin Mason Iv Jan 2000

Estimation And Attenuation Of Reinsurance Risk In The Crop Insurance Market , Charles Edwin Mason Iv

Retrospective Theses and Dissertations

Because of the high level of systemic risk in farming, crop insurance has failed to be provided by the market without government involvement. Currently, in addition to subsidy support the Federal government aids the crop insurance industry by providing reinsurance services to crop insurance companies. This means that the government will reimburse insurers for a large portion of their losses in years when indemnities to farmers are high. In exchange, portions of firms' profits are paid to the government when indemnities are below premiums;This study measures the level of risk accepted by the government in its role as reinsurer ...
