Special Issue Information

Dear Colleagues,

Throughout history, there have been several definitions of the role of agronomy in yield improvement. Jonathan Swift wrote, some 300 years ago, “that whoever could make two ears of corn, or two blades of grass, to grow upon a spot of ground where only one grew before, would deserve better of mankind, and do more essential service to his country than the whole race of politicians put together”.

The production of crop plants is one of the most ancient activities. In all ages, it has provided food, feed, and several other products that can be used for further processing. The basic task of land use for crop yield improvements is quite simple: the harmonization between crop plant requirements and production site characteristics. In general, there are several efficient yield-improving factors. There are studies focusing on management technologies such as (1) the application of different genetical backgrounded materials and the variety of usage; (2) adaptation to different agroecological environment; (3) crop rotation methods; (4) manuring and fertilization; (5) tillage methods; (6) any parameter of sowing and planting; (7) plant care and phytosanitary (including irrigation); (8) harvest methods and parameters; and (9) post-harvest technologies (including storage problems like Fusarium mycotoxin production).

This Special Issue aims to assess the effects of agricultural management, efficient agronomic practices, and the utilization of proper crop species and varieties on crop yield. This Special Issue closely encompasses the aims and scope of Agriculture, involving crop management, land–crop systems, and yield 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 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. Agriculture 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The cultivation of horticultural plants in controlled greenhouse environments is a pivotal practice in modern agriculture, offering the potential to enhance crop productivity and mitigate climate change effects. This study investigates the biomechanical properties and lignin content of various Capsicum annuum mutant lines—‘fragile-plant’ (frx), ‘tortuous internodi’ (tti), and ‘puffy-structured stem’ (pfi)—in comparison to a commercially established variety, ‘Garai Fehér’. We employed the acetyl bromide method to quantify lignin content and conducted three-point bending tests to assess rigidity in three distinct regions of the stem. Gene expression analysis of key lignin biosynthetic pathway genes (PAL, C4H, 4CL, CCoAOMT, CAD) was performed using qRT-PCR. The results revealed significant differences in lignin content and breaking force among the genotypes and stem regions. The tti mutants exhibited similar lignin content to the control but lower breaking strength, likely due to elongated internodes. The frx mutants showed uniformly reduced lignin content, correlating with their fragile stems. The pfi mutants displayed abnormally high lignin content in the top region yet demonstrated the lowest stem rigidity in every region. Overexpression of CAD and CCoAOMT was detected in the mutants in specific regions of the stem, suggesting alterations in lignin biosynthesis; however, we could not confirm the correlation between them. Our findings indicate that while lignin content generally correlates with stem rigidity, this trait is complex and influenced by more factors. Full article
