Special Issue Information

Dear Colleagues,

Reactive oxygen species (ROS), e.g., ozone and H₂O₂, used in various areas of science and industry, are an effective tool for influencing chemical and biological processes. Agriculture has shown a trend of moving away from chemical compounds, the use of which carries negative consequences, in favour of those that are safe for both the environment and consumers. ROS use can contribute to environmental protection as they do not leave residues, unlike other, more complex chemical compounds.

Included in this Special Issue are studies that analyse the harnessing of ROS to enhance crop performance, including improving plant physiology, stress tolerance, growth, yield, and post-harvest quality. Contributions may cover multiple crop types and explore responses at the cellular or molecular level. At the same time, this Special Issue will reduce the use of products with negative environmental impacts.

This Special Issue focuses on scientific advances in agricultural tools within the scope of sustainable crop management and performance improvement.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The aim of the study was to determine, under field conditions, the effects of O3, H2O2, and fungicide protection on potato late blight severity, SPAD values, tuber yield, and mineral composition, and additionally to assess whether the number of ozone applications modifies selected tuber quality traits. Two complementary field experiments were conducted in 2017 and 2018. In the main experiment, control, fungicide protection, ozone fumigation, and foliar H2O2 treatments were compared with respect to late blight severity, SPAD response, yield, and macro- and micronutrient contents in tuber peel and flesh. In the supplementary experiment, single, double, and triple ozonation were compared in relation to starch content, vitamin C concentration, and tuber mineral composition. Fungicide treatment most effectively limited late blight symptoms, particularly at later assessment dates, and was associated with the highest tuber yield. SPAD values, yield, and several mineral traits were strongly dependent on the study year, indicating a major contribution of environmental conditions. The response to O3 and H2O2 was selective and less stable than that observed under fungicide protection. In the supplementary experiment, the number of ozone applications did not significantly affect starch content. Vitamin C concentration depended mainly on the study year, whereas tuber mineral composition depended mainly on year and tissue type. The results indicate that, under field conditions, fungicide protection remained the most effective option for limiting late blight and achieving the highest tuber yield, whereas O3 and H2O2 should be regarded as factors capable of modifying selected plant and tuber traits, but not as direct substitutes for standard chemical protection.
