“…Therefore, plant yield depends on the influence of genetic and environmental factors on seed quality. In this regard, using efficient strategies developed to improve seed germination, growth power, and crop productivity is one of the main targets of sustainable agriculture (Howyzeh et al, 2015; Rasooli et al, 2021).…”

Current research is considered to study the effect of nonthermal physical field technologies of atmospheric cold plasma (CP) and ultrasound waves (US) on the germination and seedling indices of cumin seeds. In this regard, different drying strategies were planned in a single and combined form using a lab-scale cold plasma unit and ultrasound-assisted air dryer. Various duration of CP pretreatment (CPt: 0, 15, and 30 s), ultrasound power (P: 0, 60, 120, and 180 W), and air temperature (T: 30, 35, and 40 C) were practiced to investigate the changes in germination traits and microstructure characteristics of cumin seeds. It was found that CP pretreatment and ultrasound treatment in a single form significantly increased germination percentage, germination index, and germination rate as well as seeding vigor of cumin seeds. The morphological alteration in the surface of the seeds, which modifies the seed surface hydrophilicity and accelerates water uptake, may be the leading cause of CP and USinduced modification in the germination power. The highest stimulatory effect belonged to the combined application of cold plasma and ultrasound wave when the cumin seeds were treated with an appropriate CP dose and ultrasound energy. So that, the maximum germination percentage (92%), germination index (14.91), and germination rate (21.33%), as well as the highest values of seedling vigor index I (178.67 mm) and vigor index II (420.72 mg), were in possession of pretreatment with CPt: 15 s before ultrasound-assisted drying at T ≤ 35 C and P ≤ 120 W. Practical ApplicationsThis study demonstrates the potential of cold plasma and ultrasound wave before and during air drying of cumin seeds, respectively. Cold plasma was used as a nonthermal and nonchemical pretreatment strategy before air drying of cumin seeds in ultrasoundassisted dryer. A single application of cold plasma caused a significant increase in germination percentage, germination index, and germination rate of cumin seeds. The positive effect of cold plasma on the studied parameter of cumin seeds intensified when it was supported by airborne low-power ultrasound waves during air drying.

Bacillus velezensis is a kind of beneficial bacteria that is widely used in agriculture industry. Bacillus velezensis was irradiated with corona discharge generated by a needle-array high-voltage electrode. The results showed an improvement of activity of Bacillus velezensis by the corona discharge treatment was confirmed at an optimum input energy. Mutation of the Bacillus velezensis by the corona discharge treatment was also confirmed through an rRNA sequence alignment analysis. The enzyme activity of the mutated bacteria was greatly improved, which was a positive effect that can meet the production demand.

“…Priming improves essential metabolic pathways by inducing high osmotic potential during abiotic stress that prevents seeds to absorb enough water for radicle emergence by suspending the lag phase and inhibit germination [ 18 – 20 ]. The priming techniques are the most effective ways of reducing germination time and improving total germination percentage, to enhance yield [ 20 ]. Various seed priming methods are used to improve germination and vigor.…”

“…Seed germination and fast seedling growth are the very sensitive stages [11][12][13][14][15][16][17] for improved black cumin production, which is mainly grown under rainfed conditions with unfavorable and no-uniform moisture contents. Priming improves essential metabolic pathways by inducing high osmotic potential during abiotic stress that prevents seeds to absorb enough water for radicle emergence by suspending the lag phase and inhibit germination [18][19][20].…”

Central Anatolia is prone to drought with low precipitation and high evapotranspiration which influence the growth of a several crops. The selection and cultivation of drought-tolerant crops that can survive and maintain under poor climatic conditions are very important. Black cumin (Nigella sativa L. Umbelliferae) is famous for aromatic, medicinal, and therapeutic uses in the Mediterranean region and elsewhere. Drought stress most often delays or reduces seed germination ending up in irregular and poor crop growth. The study aimed to compare the effects of −0.1, −0.2, and −0.4 MPa of PEG 6000 osmo-priming pretreatments for 12, 24, and 36 h and two PEG 6000 post-treatments of −0.05 and −0.15 MPa along with their respective controls for 14 days as post-treatment on seed germination and seedling establishment potential of Turkish cv. Cameli. The results showed significant differences among germination index, germination stresses tolerance index, germination speed, final germination percentage, seedling vigor index, mean germination time, shoot, root and seedling length, and seedling fresh and dry weight of pretreatments and post-treatments when compared to nonprimed and hydro-primed seeds used as control treatments. Osmo-priming pretreatments of black cumin using −0.2 or −0.4 MPa PEG 6000 for 24 or 36 hours in a medium containing −0.05 MPa PEG 6000 as post-treatment showed improved germination efficiency, with increased adaptation ability.
