| Among the different institutions through which the Costa Rican government influences production and internal marketing of agricultural commodities, the Consejo Nacional de Produccion (CNP) is the most important one. The Consejo is given by law a great deal of authority in fomenting production and stabilizing prices of food products. It is also entitled to perform a wide range of activities and marketing functions affecting the food system (buying and selling, assembling, transporting, storing and processing, importing and exporting, price fixing, input distribution, etc.). Because of the strategic role of agriculture in the country, and due to very significant influence of the Consejo's intervention upon production, marketing and consumption in... |

| Cover crops can help reduce the negative environmental impacts of cotton production. Using time series yield data, this study utilizes generalized stochastic dominance to evaluate the relative worth, via risk premiums, of three cover crop and two conventional production systems based on expected net returns of each system and decision maker risk attitude. Results indicate, within the limitation of the study, two cover crop regimes possess a high degree of dominance over conventional systems. Determination of the dominant regime depends upon the risk attitude of a specific decision maker. This research suggests cover crop production systems may be feasible alternatives to conventional practices. |

| A magyarországi zöldség- és gyümölcságazat felkészülése az uniós csatlakozásra nem volt igazán eredményes, uniós tagságunk eddigi tapasztalatai, eredményei is felemásak. A csatlakozásnak eddig több a negatív, az ágazat jövőjét veszélyeztető következménye, mint a pozitív hozadéka. A korábbi gyengeségek – alacsony szervezettség, elavult műszaki színvonal, hiányos logisztikai rendszerek, elaprózott birtokstruktúra, szélsőségesen differenciált termelési (gazdálkodási) színvonal – következtében itthon piacvesztés, strukturális feszültségek jöttek létre. Későn és lassan indult meg a gazdák összefogása, együttműködése, értékesítő tevékenységük megszervezése. A termelők gyenge piaci alkuereje kedvezőtlenül befolyásolta mind az értékesítést, mind a... |

| Az éghajlatváltozás hatásai a minőségi termelés követelményei, a rentábilis termelés igénye, a termeléstechnológiai elemek megújításának, korszerűsítésének szükségessége egyaránt sürgetik a fenti követelményeket szem előtt tartó, annak megfelelni akaró módszert, a szabadföldi intenzív termelést, melynek legfontosabb elemei: az időszakos talaj-, növény- és légtértakarás, a víztakarékos öntözési módok alkalmazása és a retardált műtrágya használata. Az időszakos talaj-, növény- és légtértakarással a szedési időszak meghosszabbítható, és egyúttal javítható a talaj vízgazdálkodása, valamint visszaszorítható a gyomosodás. A mikroöntözés alkalmazásával, azonos vízmennyiséggel kétszer akkora terület öntözhető. Retardált (fékezett lebomlású) műtrágyák... |

| The food habits and dietary patterns of American consumers are changing and they are increasingly demanding food products that possess certain attributes relating to how the food was produced or processed. The objectives of the study are to analyze household purchase of fresh tomatoes and to determine the magnitudes of the price premium paid for the organic tomatoes by estimating a hedonic price model. The study uses the 2003 ACNielsen Homescan panel data. The data set represents a nationally representative panel of U.S. households, which provide food purchase data for at-home consumption. For empirical implementation, parameters of the hedonic model were estimated using the Box-Cox transformation procedure. The results indicated that consumers value the... |

| The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of... |

| New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties. This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature. Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties. This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness. Yield was not significant explanatory variable for the willingness to pay for seed. The implications... |

| This study estimates a hedonic price equation to assess consumers' willingness-to-pay for reduction in pesticide residues in fifteen fruits and vegetables. A unique feature of the study is its employment of the FDA's Total Diet Study data which attempts to measure actual pesticide ingestion by the American public in table-ready or prepared foods. The results indicate that consumers would be willing to pay approximately $.08 per pound to reduce pesticeds by one part per million in the prepared fruits and vegetables that they consume. |

| O setor primário brasileiro é de grande importância para sua economia e a lavoura orizícola gaúcha está inserida nesse contexto, também com grande relevância, pois tem significativo número de produtores que auferem seus rendimentos dessa atividade. Entretanto, há uma redução de rentabilidade no setor atribuída às Importações Mercosulinas que, alegam os produtores brasileiros, pressionam os preços internos. Também, o crescimento da produção interna pode causar o mesmo efeito. Esse trabalho busca provar que o arroz importado do Mercosul e a Produção Gaúcha de arroz exercem influencia no preço interno e que as relações entre as variáveis ocorrem de forma curvilinear e não podem ser analisadas por métodos lineares. Para tanto, fez-se uso da estatística... |

| A növénynemesítés fokozatosan romló működési körülményei, a hatékony marketing és a vetőmagkereskedelem hiányosságai, a külföldi fajták nyomása következtében több növényfajban a hazai nemesítés jelentősége csökkent az utóbbi 20 évben, sőt néhány növényfaj nemesítése Magyarországon meg is szűnt. A Kompolton folyó őszi árpa nemesítés eredményesen állt helyt a külföldi fajtaelőállítók nyomásának. Fajtáink kiváló termőképessége mellett, kiemelkedő télállósággal, igen jó szárszilárdsággal, megbízható állóképességgel, összességé-ben kiváló alkalmazkodóképességgel rendelkeznek. Összesen 12 takarmányárpa és 2 őszi sörárpa fajtánkkal minden termesztési választékkal rendelkezünk. 2004-ben az OMMI kísérletekben a korai és a középérésű csoportban is két-két fajtánk... |

| It is shown that the first-order differential acreage allocation model developed by Bettendorf an Bloome and by Barten and Vanloot, and based on certainty equivalent profit maximization, may be extended to a levels version. The levels model, referred to as a linear approximate acreage allocation model, is potentially useful when panel or cross-sectional data are employed. An empirical application with U.S. state-level corn flex acreage data for the period 1991-95 indicates the feasibility of the approach. Estimated price and scale elasticities are generally larger than previous estimates, and are perhaps indicative of acreage response under the provisions of the 1996 Farm Act. |
