The Paraná State in Southern Brazil is the second most soybean producer from Brazil; Paraná comes behind only the Mato Grosso state in Brazilian central area. This paper aims to analyze the soybean trend and spatial variation productivity data, as well as carry out a social and economic characterization of the municipalities producers and thus create regional indicators unfold different patterns of productivity of soybean in a representative region of Paraná in the years between 1999 to 2010. To finish this research was collected soybean data from 132 counties. These counties represent the southern slope of Paranapanema river basin. Was applied two statistic testes: Mann-Kendall and the Ward. The results were represented in cartographic system and boxplots graphics and they showed the visible soybean yield crop and spatial variation between all counties. The crop and spatial variation have relation with agriculture characteristics analyzed by IBGE data.Downloads

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments.

Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
