Accommodating Imperfect Competition in A Model of World Peanut Trade AgEcon
Fletcher, Stanley M.; Nadolnyak, Denis A..
In this paper, we make an attempt to rationalize the strategic behavior of major peanut exporting and importing countries in the framework of imperfectly competitive markets with the focus on the global and inter-American peanut trade. This study is motivated by the fact that liberalizing imperfectly competitive and often distorted markets can have unorthodox effects, in particular increase the incentives to overuse certain trade policies. The results suggest that the South American peanut producers stand to benefit from the reductions in the U.S. peanut production supports but, paradoxically, preservation of a tariff may still be mutually welfare enhancing. In the broader context of global peanut trade, multi-lateral tariff reduction increases the...

Adubação foliar de boro em diferentes estádios fenológicos da cultura do amendoim. Repositório Alice
MANTOVANI, J. P. M.; CALONEGO, J. C.; FOLONI, J. S. S..
Resumo: A adubação boratada foliar, na cultura do amendoim, pode ser uma estratégia viável para fornecimento desse elemento à planta; porém, são poucos os conhecimentos sobre dosagens, épocas e efeitos de parcelamento das doses. O objetivo deste trabalho foi avaliar as características de produção e a composição mineral foliar em diferentes doses, épocas de aplicação e parcelamentos da adubação boratada. O experimento foi conduzido na safra de verão 2010/2011, em Latossolo Vermelho distroférrico, em Rubiácea (SP). Foram estudadas as doses de zero; 0,5; 1,0; 1,5 e 2,0 kg ha -1 de boro (B), aplicadas por via foliar, utilizando-se como fonte o ácido bórico. Os efeitos da adubação boratada foram testados em doses únicas nos estádios V1 ou R5, além do...

An Analysis of Latin American Peanut Trade AgEcon
Lee, Dae-Seob; Kennedy, P. Lynn; Fletcher, Stanley M..
The U.S. export share in the world peanut market has decreased due to heavy competition. In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR). Based on these estimations, a scenario analysis was conducted. The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks. The effects of price changes on net trade are noticeable. However, the world price does not significantly affect the Latin American peanut supply. The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

Bioactivity of basil (Ocimum basicilum L.) on control of the spider mite (Tetranychus urticae Koch.) in peanut. Repositório Alice
MARTINS, M. I. G.; SANT'ANA, A. E. G.; VASCONCELOS, F. M. T.; SILVA, W. L.; LIMA, L. M. de; CARVALHO, R.; MELO FILHO, P. A.; SANTOS, R. C. dos.
Essential plant oils contain biopesticides that could be used to control many crop pests. Tetranychus spp. are mites that cause damage to several crops and are primarily controlled by synthetic pesticides. Literature showed that mites can be controlled with essential oils of plants containing eugenol. In this work, we evaluated the bioactivity of basil (Ocimum basicilum) accessions for peanut-spider mites control based on molecular, biochemical and agronomic assays. RNA from four basil accessions, previously chosen by divergence genetic analysis, were used to estimate the expression of eugenol synthase (EGS I) transcripts, by semiquantitative and polymerase chain reaction (qPCR) assays. Chromatography was, thereafter, performed in order to estimate the...

Bonnes pratiques agrícoles pour réduire le risque de contamination par l'aflatoxine dans la production d'Arachides au Mali. Infoteca-e
SUASSUNA, T. de M. F.; CARTAXO, C. B. da C.; GONDIM, T. M. de S.; BABANA, AMADOU HAMADOUN; BORIN, A. L. D. C.; SUASSUNA, N. D.; COUTINHO, W. M.; ALMEIDA, R. P. de; DI STEFANO, J. G.; TRAORÉ, D.; MAIGA, K.; DIARRA, O..
L'arachide est un oléagineux très important pour l'alimentation humaine et animale, en tant que source d'énergie, de protéines, de vitamines et de minéraux. Cependant, les arachides sont sensibles à la contamination par les aflatoxines: substances toxiques produites par des champignons du genre Aspergillus, avec des effets cancérigènes, mutagènes et tératogènes. Dans ce contexte, les bonnes pratiques agricoles dans la production d'arachides visent à réduire le risque de contamination par les aflatoxines. Dans l'ensemble, la qualité et la sécurité de la production exigent des connaissances sur la gestion des cultures et post-récolte, afin d'éliminer les conditions favorables aux champignons producteurs d'aflatoxine dans les étapes de production, récolte,...

Bradyrhizobium spp. as attenuators of water deficit stress in runner peanut genotypes based on physiological and gene expression responses. Repositório Alice
BRITO, S. L.; SANTOS, A. B.; BARBOSA, D. D.; FERNANDES, P. D.; FERNANDES JUNIOR, P. I.; LIMA, L. M. de.
The peanut plant has high plasticity and great adaptability to adverse conditions, including drought. To mitigate the negative effects of drought on legumes, nitrogen-fixing microorganisms have been investigated in some plant species, such as soybeans and beans. We analyzed the role Bradyrhizobium strains in peanut genotypes subjected to water deficit by means of plant growth, physiological and gene expression analysis. The research was conducted under greenhouse conditions with the runner peanut genotypes (IAC Runner 886, 2012-33 and 2012-47) and two Bradyrhizobium strains (ESA 123 and SEMIA 6144). After 20 days of germination, the water supply was completely interrupted and gas exchange analysis were carried out using an infrared gas analyzer, up to the...

Can Bradyrhizobium strains inoculation reduce water deficit effects on peanuts? Repositório Alice
BARBOSA, D. D.; BRITO, S. L.; FERNANDES, P. D.; FERNANDES JUNIOR, P. I.; LIMA, L. M. de.
Drought is one of the environmental factors that most affects peanut cultivation in semi-arid regions, resulting in economic losses to growers. However, growth promoting bacteria are able to reduce water deficit damage in some plant species. In this context, this study aimed to evaluate the interaction of Bradyrhizobium strains reducing water stress effects on peanut genotypes by antioxidant enzymes activities, leaf gas exchanges and vegetative growth, as well as to determine the taxonomic positioning of strain ESA 123. The 16S rRNA gene of ESA 123 was amplified by PCR and sequenced by dideoxy Sanger sequencing method. An experiment was performed in greenhouse with three peanut genotypes (BRS Havana, CNPA 76 AM and 2012-4), two Bradyrhizobium strains...

Can Rank-Order Tournaments Improve Efficiency of Quality Differentiated Crop Markets Under Marketing Loan Program Operation? The Case of U.S. Peanuts. AgEcon
Nadolnyak, Denis A.; Fletcher, Stanley M.; Revoredo-Giha, Cesar.
In the paper, alternative contractual arrangements between crop producers and processors are evaluated with a view of addressing the major issues present in peanut markets in the U.S., the major EU supplier of high quality peanuts. The issues are the thinness of the spot markets and the absence of quality premiums, both of which impair market efficiency. Results indicate that introducing contracts with a system of quality differentials creates incentives for producer self-selection to participate in the post harvest cash market. Moreover, in the presence of sufficiently high common production risk, tournament contracts are more efficient and preferred by the producers than the standard fixed premium schedules.

CONTRACT MARKETING IN THE US AFTER THE 2002 FARM ACT: THE CASE OF PEANUTS AgEcon
Revoredo-Giha, Cesar; Nadolnyak, Denis A.; Fletcher, Stanley M..
The elimination of the marketing quota system that regulated the peanut market since the 1930s has been accompanied by the emergence of marketing contracts between farmers and peanut buyers (mainly peanut shellers). Two types of contracts have been observed, forward contracts for delivery at harvest or at a later date and “option to purchase” contracts. We analyze the clauses of contracts used by major shellers in order to infer the motivation behind these contracts (i.e., risk sharing, reduction of transaction costs, improve coordination, exercise of market power, etc.). The analysis points out that the main role of the contracts is to replace the marketing structure existing prior the 2002 Farm Act, where peanut marketing was quite regulated. In this...
