Plasma-activated water (PAW) is a sustainable and innovative alternative for agriculture, especially in controlled environments like greenhouses. Tomato pepper are key horticultural crops worldwide, with considerable part of their production This study examined the effects PAW irrigation on seed germination, plant growth, oxidative stress tomato bell plants. was activated up to 15 min using 1 L capacity plasma reactor based glow-type discharge air water-cathode. The concentration nitrogen compounds energy efficiency synthesis obtained were moderately high (5.4 mM 60 nmol/J, respectively). most notable observed pepper. germination percentage increased by 26%, while no significant found seeds. significantly promoted dry weight increasing 61% 42% tomato. Lipid peroxidation results showed damage either crop. biochemical analysis antioxidant enzymes (catalase, superoxide dismutase, guaiacol peroxidase) confirmed that defense systems responded adequately irrigation. These highlight PAW’s potential as an eco-friendly agriculture.

Non-Thermal Plasma as Environmentally-Friendly Technology for Agriculture: A Review and Roadmap

Critical Reviews in Plant Sciences, Год журнала: 2024, Номер 43(6), С. 428 - 486

Опубликована: Окт. 10, 2024

New approaches are required in the agricultural sector to keep pace with ever-growing demand for food context of climate change and resource deterioration avoiding further negative impact on environment. Nonthermal plasma is an environmentally-friendly technology which could make a difference future production. This review intends introduce topic agriculture broad audience by describing detail various sources potential applications, as well effects exposure seeds, both at macroscopic scale, concerning intimate mechanisms occurring inside plant. Examples meant illustrate effect seeds plants have been selected among extensively investigated species, such cereals legumes, few species that less often reported literature, medicinal woody plants. Generally, main all types consist increased germination, higher plant yield, seed decontamination, sometimes tolerance stress factors. These due physical chemical interaction followed response cell mechanisms, addressed paper. Finally, crucial aspects regarding practical application nonthermal discussed challenges perspective treatments.

Air cold plasmas as a new tool for nitrogen fixation in agriculture: underlying mechanisms and current experimental insights

Frontiers in Physics, Год журнала: 2024, Номер 12

Опубликована: Окт. 9, 2024

Nitrogen fixation is crucial for plant growth and global agriculture, especially with the projected population requiring a significant increase in food production. Traditional nitrogen relies on Haber-Bosch (H-B) process, which energy-intensive environmentally harmful due to greenhouse gas emissions. Emerging technologies, such as cold plasma, offer promising alternatives lower energy consumption. Cold plasma facilitates reactive species generation under ambient conditions, potentially improving production efficiency of oxides (NO x ). However, optimizing requires synergy between experimental theoretical approaches. Accurate input data are essential refining models, can then guide design more efficient processes. This integrated approach leverage renewable energy, operate smaller scales, minimize environmental impacts, making sustainable solution future needs.

Plasma Optimization as a Novel Tool to Explore Plant–Microbe Interactions in Climate Smart Agriculture

Microorganisms, Год журнала: 2025, Номер 13(1), С. 146 - 146

Опубликована: Янв. 13, 2025

Plasma treatment has emerged as a promising tool for manipulating plant microbiomes and metabolites. This review explores the diverse applications effects of plasma on these biological systems. It is hypothesized that will not induce substantial changes in composition or concentration We delve into mechanisms by which can regulate microbial communities, enhance antimicrobial activity, recruit beneficial microbes to mitigate stress. Furthermore, we discuss optimization parameters effective microbiome interaction role plasmids plant-microbe interactions. By characterizing plasmidome responses exposure investigating transcriptional metabolomic shifts, provide insights potential engineering The presented herein demonstrates induces both community metabolite levels, thereby refuting our initial hypothesis. Finally, integrate plasmidome, transcriptome, metabolome data develop comprehensive understanding plasma's biology explore future perspectives agricultural applications.

Large-Scale Plasma-Activated Water Reactor: The Differential Impact on the Growth of Tomato and Bell Pepper Plants in Nutrient-Rich and Nitrogen-Free Substrates

Agronomy, Год журнала: 2025, Номер 15(4), С. 829 - 829

Опубликована: Март 27, 2025

In this study, plasma-activated water (PAW) was generated using a large-volume (5 L) plasma reactor with quasi-stationary, water-cathode glow-type discharge in atmospheric pressure air. Tap activated up to 75 min. PAW exhibited high concentrations of long-lived reactive nitrogen species (RNSs), reaching 8 mM, which is between 4 and 26 times higher than those reported previous studies. The reached an RNS synthesis efficiency 61 nmol/J production rate 526 μmol/min, both among the highest reported. evaluated on tomato bell pepper. Seedling emergence determined nutrient-free substrate. To assess plant growth, seedlings were transplanted into pots filled either nitrogen-free or nutrient-rich PAW-irrigation significantly promoted seedling leaf expansion, especially plants. growth-stimulating effects more pronounced substrate: fresh weight pepper increased 13.1-fold 2.6-fold, respectively. contrast, effect substrate negligible. Tomato plants grown irrigated 75-min dry comparable irrigation did not induce oxidative stress, as confirmed by malondialdehyde (MDA) levels antioxidant enzyme activity.
