Plant Nutrition in Alleviating Abiotic Stress

Dear Colleagues,

Producing food in sufficient quantity and quality for a constantly growing population represents one of the greatest challenges nowadays, considering that crops are exposed to several abiotic stress factors, such as drought, flooding, heat, frost, and salinity. The survival and productivity of crops depend fundamentally on their ability to identify and deal with stress factors through the adjustment of tolerance mechanisms. This ability to adapt and modulate its metabolism is intrinsic to each genotype but is strongly associated with the nutritional status of the plant. Thus, we must better understand the relationship between plant nutrition and tolerance mechanisms against abiotic stress to optimize fertilization practices. In addition, although some studies have been describing the benefits of nutrients, beneficial elements, and biostimulants in mitigating abiotic stresses, there is a huge lack of information regarding the best dose, time, frequency, and method of application (4R nutrient stewardship) in annual, semi-perennial, and perennial crops. There is also little information regarding which nutrients, beneficial elements, or biostimulants that should be applied to mitigate each type of stress and whether they should be applied alone or in combination with other products. In this context, this Special Issue is focused on covering aspects of plant nutrition in alleviating abiotic stress, from studies aimed at better understanding how plant nutrition modulates the tolerance mechanisms of plants exposed to abiotic stress to practical applications of nutritional products in the field.

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. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.
