Evapotranspiration Soybean: Comparison Between Eddy Covariance Method and the Estimate of Cropgro-Soybean Model
Keywords:DSSAT . Till. Water balance in soil.
The performance of CROPGRO - Soybean model for soybean evapotranspiration simulation was assessed using data derived from field experiments using eddy covariance method conducted by Network Sulflux (Brazilian South Network Surface Flows and Climate Change ) Cruz Alta, Rio Grande do Sul State - Brazil , (28° 36' S, 53° 40' W and altitude 409 m), in the agricultural year 2009/2010. The results indicate that the model overestimates evapotranspiration throughout the crop cycle, probably it does not represent realistically the crop residues, indicating a need for adjustments in water balance parameters in the soil in no-till system.

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.
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.
