The objective of this study is to (i) analyze the recommendation of the need for irrigation for soybean crops using the methodology of calculating the water balance measured by monitoring soil moisture by the TDR sensor, (ii) verify the impacts of irrigation on soybean productivity and water use efficiency, and (iii) compare this irrigation recommendation with those generated by the calculation and simulation of the water balance following the FAO methodology - without using the soil moisture parameters observed by the TDR, for the 2022/2023 harvest in Cachoeira do Sul/RS. Thus, the study was divided into a field stage and a simulation/calculation stage. The water supplementation of 295.6 mm via irrigation contributed to the increase in all productivity components and in the final soybean productivity, which was 4,370.8 kg ha-1 (irrigated) and 2,473.6 kg ha-1 (rainfed). On the other hand, water use efficiency was higher in conditions of lower water availability of 16.4 kg mm-1 (rainfed) and 9.8 kg mm-1 (irrigated). The calculation and simulation of the water balance performed from data obtained in the field, using the methodology of FAO bulletin – 56, recommended a higher number of irrigations, totaling a higher accumulated depth for the cycle of 420.0 mm (calculated) and 405.0 mm (simulated Cropwat), highlighting the importance of monitoring soil moisture in methodologies for recommending the need for irrigation.

The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. 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 An Editor must not use unpublished information in the editor's own research without the express written consent of the Author.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.
