Enhancing Nitrogen Use Efficiency in Major Crops: Mechanisms, Management, and Synergies with Yield Formation
This special issue belongs to the section "Farming Sustainability".
Special Issue Information
Dear Colleagues,
Nitrogen use efficiency (NUE) is a key determinant of crop productivity, resource use efficiency, and the sustainability of agroecosystems. For major food and cash crops, such as rice, wheat, maize, and oilseed rape, numerous studies have been conducted to improve NUE through various management practices. However, under diversified field management conditions (e.g., different irrigation regimes, fertilization strategies, tillage practices, and cropping systems), crop NUE varies considerably. The response patterns of NUE, the mechanisms underlying its improvement, and its linkages with crop yield formation remain incompletely understood.
This Special Issue focuses on major food and cash crops, with nitrogen use efficiency systematically examined under different irrigation, fertilization, and agronomic management conditions, and with particular emphasis on effective strategies for improving nitrogen use efficiency, their underlying mechanisms, and clarifying the relationships between nitrogen use efficiency and crop yield formation processes.

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-anonymized 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.
