Última Effect of Prices, Traits and Market Structure on Corn Seeding Density AgEcon Mitchell, Paul D.; Shi, Guanming; Ma, Xingliang; Lauer, Joseph G.. Recent agronomic research finds that economically optimal seeding densities have likely increased for many Midwestern corn farmers as a result of genetic improvements including new GM traits such as Bt corn and herbicide tolerance. We derive a per acre demand model for hybrid seed corn to examine the determinants of corn seeding densities and estimate the model using a large data set of individual farmer seed corn purchases. Current results identify factors other than prices affecting farmer corn seeding densities. Among these factors are the GM trait of the seed corn, measures of the local seed corn market structure, seed purchase source and intended end use. We interpret these effects in terms of information effects—farmers with more/better access to...

Ano: 2009 URL: http://purl.umn.edu/49520 FARM-LEVEL EFFECTS OF ADOPTING HERBICIDE-TOLERANT SOYBEANS IN THE U.S.A. AgEcon Fernandez-Cornejo, Jorge; Klotz-Ingram, Cassandra; Jans, Sharon. This paper estimates the on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization. The model is estimated using nationwide farm-level survey data for 1997. Given that the use of herbicide-tolerant soybeans involves the substitution of a particular herbicide - primarily glyphosate - for other herbicides, we explicitly consider this substitution process in the model.

Ano: 2002 URL: http://purl.umn.edu/15522 Production of herbicide-resistant coffee plants (Coffea canephora P.) via Agrobacterium tumefaciens-mediated transformation BABT Ribas,Alessandra Ferreira; Kobayashi,Adilson Kenji; Pereira,Luiz Filipe Protasio; Vieira,Luiz Gonzaga Esteves. Transgenic plants of Coffea canephora P. resistant to the herbicide ammonium glufosinate were regenerated from leaf explants after co-culture with Agrobacterium tumefaciens strain EHA105 harboring pCambia3301, a plasmid that contains the bar and the uidA genes both under control of 35S promoter. Direct somatic embryogenesis was induced on basal medium contained ¼ strength macro salts and half strength micro salts of MS medium, organic constituents of B5 medium and 30 g.L-1 sucrose supplemented with 5µM N6 - (2-isopentenyl)-adenine (2-iP). Ten µM ammonium glufosinate was used for putative transgenic somatic embryos selection. Presence and integration of the bar gene were confirmed by PCR and Southern blot analysis. Selected transgenic coffee plants sprayed... Tipo: Info:eu-repo/semantics/article Palavras-chave: Genetic transformation; Coffee; Herbicide tolerance; Ammonium glufosinate.
