Special Issue Information

Dear Colleagues,

Climate change caused by changes in the temperature, distribution, and availability of water, soil pH, humidity, compactness, and availability of nutrients contributes to changes in biodiversity and have a very significant impact on agriculture and the environment. These changes pose a serious threat to food security and humanity in the 21st century. Knowledge of biology and proper management of plants in the conditions of climate change are very important.

The progressive degradation of the natural environment, its pollution, and, consequently, climate change indicate the need to develop an interest in these issues and the necessity of monitoring studies in the conditions of climate change.

The rapid growth of the human population forces us to secure our protein needs. Legumes are an excellent option that is gaining increasingly favor and are a valuable source of food for both humans and animals.

This Special Issue aims to collate research papers describing cereal and legume cultivation systems in the conditions of climate change. Top-level research will be taken into account if the above topics are used to develop cultivation and management systems of plant production in the agricultural sector.

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.

In the face of climate pressure and threats to biodiversity, intercropping cereals with legumes and using biostimulants can increase feed yield and quality. This research evaluated a two-year intercropping system of maize and climbing beans for silage in central Poland, comparing four sowing schemes 90,000 ha−1 maize with 90,000 (90 + 90); 45,000 (90 + 45) or 27,500 (90 + 27.5) climbing beans ha−1 and sole maize, as well as five biostimulant application: control object, liquid microelement fertilizer (Zn-8.0%) containing zinc acetate, liquid extract from Ecklonia maxima algae, Methylobacterium symbioticum bacteria, Bacillus halotolerans bacteria. The aim of the field research was to evaluate the biomass components, yields, and crude protein content in silage. The intercropping pattern and biostimulants had a significant effect on dry matter and yields, with limited interactions. Single maize plant weight and yield were highest in the single crop and 90 + 27.5 treatments, while total intercrop yield peaked at 90 + 45, exceeding single maize by 14%. Biostimulants increased maize yields by 3–8% and intercrop yields by up to 6%, but reduced bean yields compared to controls. The crude protein content of silage was lowest for maize alone and highest for 90 + 45; biostimulants increased protein content by 5–9%, mainly for Methylobacterium symbioticum. Overall, the combination of 90 + 45 with Ecklonia maxima or Methylobacterium symbioticum optimized silage biomass and protein. The presented research is the first to evaluate the intercropping of maize with runner beans in orderly sowing and under the influence of biostimulants. It may constitute an important step in improving the efficiency of intercropping for implementation in agricultural practice. Further research should evaluate reduced mineral fertilization in this system. Full article

The adoption of biological control strategies plays a crucial role in ensuring the sustainability of organic agricultural practices. A field experiment was conducted in 2023 and 2024 to evaluate the impact of biological treatments using lactic acid bacteria (LAB) Lactiplantibacillus plantarum and mycoparasitic fungus (MPF) Trichoderma virens applied through seed treatment and foliar application separately and in combination on agronomic characteristics and pea yield in organic cultivation. Seed treatment with LAB and MPF resulted in a notable improvement in shoot length and root dry weight, while an increase in root nodule number was observed exclusively with LAB. The combined application of MPF as a seed treatment and LAB as a foliar application at the flowering stage significantly enhanced pod weight per plant, seed number per pod and per plant, and seed weight compared to treatments with LAB applied as either a foliar or seed treatment separately, as well as the untreated control. However, the yield responses to individual and combined treatments under field conditions demonstrated variability and inconsistency. Protein content ranged from 21.24% to 21.61%, and no significant differences observed between treatments. This is the first field report directly comparing the effectiveness of treatments on organic pea production. The findings offer promising avenues for assessing the long-term impacts of these treatments on the sustainable intensification of pea cultivation. Full article
