COMO proteger a lavoura de inverno: programa 22: Sul.

COMPETITIVE BIDDING ON IMPORT TENDERS: THE CASE OF MINOR OILSEEDS

O Prosa Rural desta semana apresenta alternativas de como proteger a lavoura de inverno. A produção de grãos no Brasil, no clima subtropical, quente e úmido, é um verdadeiro desafio para a agricultura brasileira. O clima favorece o aparecimento de doenças nos cereais de inverno, como manchas, fungos e bacterioses, que exigem do produtor e da assistência técnica todo um conhecimento das medidas de proteção de plantas: desde o monitoramento da lavoura, limitações no uso de fungicidas, até o momento adequado para as aplicações, por exemplo. No programa desta semana, você saberá sobre os estudos realizados pela Embrapa Trigo sobre o assunto e conhecerá a importância do monitoramento das lavouras de inverno como forma de reduzir danos e maximizar lucros.

Auctions and bidding play an important role in agricultural marketing. A common and noteworthy application of auctions and bidding is that of import tendering which is used for both price determination and the allocation of purchases among sellers. In this study we develop a model to evaluate bidding strategies and competition in Egyptian oilseeds imports. Information included the values of bids submitted by each supplier in each tender over the period 1990 to 1993. Results indicate that generally bids could be predicted for all bidders with a relatively high degree of confidence using simple relationships and accessible data. In addition, for each oil tender there appeared to be groups of bidders characterized by differences in their bid functions....

Dietary Assessment of Major Trends in U.S. Food Consumption, 1970-2005

Wells, Hodan Farah; Buzby, Jean C..

This report examines major trends in the amount of food available for consumption in the United States between 1970 and 2005 using data from the ERS Food Availability (Per Capita) Data System. The report also estimates whether Americans are meeting Federal dietary recommendations for each of the major food groups by comparing the data with dietary recommendations in the 2005 Dietary Guidelines for Americans and the MyPyramid Food Guidance System. Findings show that Americans do not meet the Federal dietary recommendations. In order to meet them, Americans would need to substantially lower their intake of added fats, refined grains, and added sugars and sweeteners and increase their consumption of fruits, vegetables, whole grains, and lowfat milk and milk...

Gray, Richard S.; Smith, Vincent H..

The United States and Canada share the longest common border and largest bilateral trading relationship in the world. Recent trading agreements--CUSTA, NAFTA and WTO--have enhanced trade by encouraging elimination of many remaining trade barriers. However, one cause for concern about the effectiveness of these trade agreements has been the frequency of Canadian-U.S. trade disputes over bilateral wheat and barley trade arrangements and trade flows. To some extent, these disputes have arisen because of differences in and lack of harmonization between the domestic and trade policies implemented by the two countries, although other political factors have also clearly been important causes of these disagreements. Since 1986, many dimensions of the agricultural...

Linking Farmers to Markets: The Case of Grain Marketing Information in Western Kenya

Odendo, Martins; De Groote, Hugo.

Market liberalization created a situation where there are no guaranteed grain prices, no central information source and the need for marketing information increased. Unfortunately, most farmers have little or no access to marketing information. This study evaluates farmers’ perceptions of importance of marketing information; identifies farmers’ sources of grain marketing information; determine farmers’ confidence in and use of marketing information; and assesses determinants farmers’ willingness (WTP) to pay for marketing information. Data used in this study were generated using a structured questionnaire in a survey that covered a random sample of 120 households in traditionally grain surplus-and deficit zones of Kenya. The data were analyzed by...

Among the traits that may add commercial value to maize (Zea mays L.), those related to nutritional quality, specially protein and oil content, are of great interest to the feed industry. The objective of this work was studying the variability of protein and oil content, as well as yield, in a group of maize testcrosses. One hundred and twenty S1 families of the ESA23B maize population were crossed with two testers, an open-pollinated population (BR108) and an exotic line (CML269). Testcrosses were evaluated at two locations under a completely randomized block design with three replications. Ear and grain yield, protein and oil content were evaluated. The three-way interaction location x tester x progeny was significant for all traits, except for oil...

FREITAS-SILVA, O.; CASTRO, I. M. de; TROBETE, F. M.; ASCHERI, J. L. R.; DIREITO, G. M.; PORTO, Y. D..

O presente trabalho estudou o efeito da aplicação de ozônio gasoso sobre a degradação das aflatoxinas AFB1, AFB2, AFG1 e AFG2 em milho, em três diferentes condições experimentais, de modo a se avaliar a viabilidade de um sistema-protótipo proposto para ozonização. A ozonização gasosa mostrou-se uma tecnologia não térmica eficaz para reduzir a contaminação por aflatoxinas em milho triturado. Os tratamentos com ozonização mais drásticos, ou seja, aqueles com maior concentração de ozônio, maior tempo de exposição e menor massa de grãos, apresentaram melhores resultados na redução da contaminação por aflatoxinas totais, alcançando valores próximos a 45%. Portanto, o sistema de ozonização proposto mostrou-se eficaz nas condições estudadas, podendo servir de...

Production and Nutrient Accumulation of Common Bean Cultivars under Competition with Weed

Planta Daninha

COELHO,C.G.; DALVI,L.P.; OLIVEIRA,L.S.G.; OLIVEIRA,F.L..

ABSTRACT: Improper management of weeds is one of the causes of low bean yield, as it is very susceptible to interference due to their slow initial growth. This study aimed to evaluate the influence of dayflower on grain yield and nutrient accumulation of bean cultivars. The experiment was carried out in a screened house, in 5 L pots, in a 2 x 4 factorial scheme. Factor 1 corresponded to the presence or absence of weeds, and factor 2 bean cultivars: BRS Pontal, BRS Agreste, BRS Ametista and BRS Estilo. The experiment was arranged in a completely randomized design with five replications. The coexistence of bean and weed was maintained throughout the crop cycle. Chlorophyll content, number of pods per plant, number of grains per plant, nutrients contents (N -...
