Special Issue Information

Dear Colleagues,

Agriculture currently faces the following two major challenges: feeding a growing world population while dealing with worsening environmental conditions. Climate change has led to more frequent and severe droughts, as well as extreme temperature fluctuations. Meanwhile, rapid industrial development has contributed to issues like soil and water salinity due to improper waste disposal, as well as heavy metal toxicity in agricultural areas due to industrial pollutants. All these abiotic stressors pose a significant threat to crop production.

This Special Issue explores the critical relationship between mineral nutrition and abiotic stress tolerance in crops. Understanding how essential nutrients regulate plant responses to adverse conditions is crucial as environmental stresses intensify. This Issue focuses on mechanisms by which mineral nutrients enhance crop resistance to abiotic stress. The scope includes research on the physiological responses, molecular mechanisms, field-scale experiments, biofortification, and soil–mineral relationships related to various abiotic stresses.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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 monthly 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.

In arid regions, yields from safflower plants are appreciably lower than normal. Foliar application of zinc or glycine betaine has been reported to increase yields in other grown crops. A field experiment was conducted to compare the specific effects and mechanisms of foliar-applied zinc or glycine betaine on safflower yield in this study. Seven foliar spraying treatments were implemented, including a control (spraying water), three concentrations of zinc sulfate (Zn1: 0.6 g L−1, Zn2: 0.8 g L−1, Zn3: 1.0 g L−1), and three concentrations of glycine betaine (GB1: 0.23 g L−1, GB2: 0.47 g L−1, GB3: 0.70 g L−1). Results showed that Zn1 treatment had the highest grain yield at 2197 kg ha−1, which was 45.4% higher than the control. GB3 treatment resulted in a grain yield at 2127 kg ha−1, which was 40.8% higher than the control. The yield increase mechanism for the zinc treatment was primarily due to optimized plant morphology and improved photosynthetic performance, while glycine betaine improved yield mainly through antioxidant regulation. This study has important implications for water-saving and sustainable agriculture development in arid regions. Full article
