Última Vegetación y etnobotánica de milpas y potreros en la región de Los Choles, en el municipio de Candelaria, Campeche. Colegio de Postgraduados Guillermo Gómez, María Asunción. Los potreros están cubriendo una proporción cada vez más grande del trópico húmedo de México, mientras el área de selvas y del cultivo de maíz ha ido en descenso. Pero, existe muy poca información sobre la composición florística y ecológica de estos pastizales inducidos. En este trabajo se compara la florística, fitogeografía, diversidad, etnobotánica y usos de la vegetación en milpas y potreros en el municipio de Candelaria, Campeche, entre la población de la etnia chol; además de que se describe el manejo de cada tipo de vegetación (milpa/potrero) con detalle. Se parte de la premisa que las milpas tendrán mayor diversidad, una proporción más grande de especies nativas y útiles, y que son recolectadas en cantidades mayores que los potreros, por ser el...

Ano: 2013 URL: http://hdl.handle.net/10521/2091 SPRAYING QUALITY OF CROP PROTECTION PRODUCTS USING TWO DROPLET SPECTRA IN THREE PERIODS OF THE DAY REA Graziano,Carlos E. P. L.; Alves,Karina A.; Gandolfo,Marco A.; Dario,Gustavo; Oliveira,Rone B.. ABSTRACT: Spraying of crop protection products can be affected by weather conditions and spray nozzles, altering deposition patterns and coverage of the target surface. The objective of this research was to analyze the quality of sprayings performed in three periods of the day (9:00 am, 2:00 pm, and 6:00 pm), using two different droplet sizes (fine and coarse) in soybeans. Coverage and deposition were evaluated in the upper, middle, and lower portion of soybean canopy. Spraying the products at 2:00 pm increased leaf coverage in the medium portion but also increased losses to the soil. Spray nozzles with fine droplet sizes provided greater coverage and deposition in the medium and upper portion of the crop for the sprayings performed in the morning. If...

Ano: 2017 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-69162017000601183 fuzzy: A program for performing qualitative comparative analyses (QCA) in Stata AgEcon Longest, Kyle C.; Vaisey, Stephen. Qualitative comparative analysis (QCA) is an increasingly popular analytic strategy, with applications to numerous empirical fields. This article briefly discusses the substantive motivation and technical details of QCA, as well as fuzzy-set QCA, followed by an in-depth discussion of how the new program fuzzy performs these techniques in Stata. An empirical example is presented that demonstrates the full suite of tools contained within fuzzy, including creating configurations, performing a series of statistical tests of the configurations, and reducing the identified configurations.

Ano: 2008 URL: http://purl.umn.edu/120930 The mixture volume sprayed by hydraulic and centrifugal energy nozzles for the control of Asian soybean rust Agronomy Costa, Lilian Lúcia; Ferreira, Marcelo da Costa; Campos, Henrique Borges Neves; Carvalho, Giorge Gomes França de; Barbosa, José Carlos. The objective of this work was to evaluate a means of controlling ASR (Phakopsora pachyrhizi H. Sydow & P. Sydow) by applying reduced fungicide volumes in association with spray nozzles using either hydraulic or centrifugal energy. Two experiments resulted from that objective: soybean plants (Glycine max (L.) Merril) of the ‘BRS Valiosa RR’ cultivar were grown at the Experimental Farm of the University of São Paulo State (Unesp) in Jaboticabal, Brazil. The treatments were distributed in the field according to a randomized complete block design with four replications. The treatments consisted of the volumes of 50, 100, and 150 L ha-1 (droplets resulting from hydraulic energy) and 17, 35, and 50 L ha-1 (droplets resulting from centrifugal energy). An...
