The main plot consisted of three drought stress levels (according to the depletion of soil available water) of 30% (I1; without stress), 60% (I2; mild stress), and 90% (I3; severe stress). The subplots were th...

Residues of pesticides, chemical fertilizers, hormonal compounds, and preservatives have caused many environmental issues. It is necessary to reduce these environmental crises by paying attention to the development of sustainable agriculture. Seed coating is considered one of the best methods to promote sustainable agriculture where the physical and physiological properties of seeds can be improved to facilitate planting, increase growth indices and alleviate abiotic and biotic stresses. Several methods of seed coating (e.g., dry powder coating, seed dressing, encrusting, seed pelleting, and film coating) are used to attain good application uniformity and adherence in the seed coating process. Seed coating has been tested in seeds of various plant species (e.g., vegetables, medicinal and other plants with small seeds) with different dimensions, forms, textures, and germination types. Plant beneficial microorganisms (PBM), such as rhizobia, bacteria, and fungi inoculated via seed inoculation can increase seed germination, plant performance and tolerance across biotic (e.g., pathogens and pests) and abiotic stress (e.g., salt, drought, and heavy metals) while reducing the use of agrochemical inputs. In this review, the microbial seed coating process and their ability to increase seed performance and protect plants from biotic and abiotic stresses are well discussed and highlighted in sustainable agricultural systems.

Two pot experiments were performed to determine mycorrhizal species effects on growth, yield, mycorrhizal dependency, root colonization, and seed quality. Under sterile soil conditions, Lallemantia iberica and Lallemantia royleana were inoculated with Funneliformis mosseae, Funneliformis caledonius, Rhizophagus intraradices, Claroideoglomus etunicatum, Claroideoglomus claroideum, Rhizophagus fasciculatus and Diversisporles epigaea. Among mycorrhizal species, Cl. etunicatum (M1), Fu. mosseae (M2) and R. intraradices (M3) were most effective on root colonization on both species of Lallemantia. In the main experiment, for both plant species of Lallemantia, the growth, yield and yield components, seed quality, and mycorrhizal dependency (MD) parameters were studied under non-sterile and sterile soil conditions using three optimal mycorrhizal species (M1), (M2), (M3), and their mixtu...

The main objectives of the current study were to investigate the effect of arbuscular mycorrhizal fungi (AMF) and nano iron chelate fertilizer under drought stress on grain yield, leaf chlorophyll contents, root colonization, oil percentage, and fatty acids profile of Lallemantia species. The experiment was carried out as a factorial based on a complete randomized block design consisting of three factors of irrigation levels of 90 (I90), 60 (I60), and 30% (I30) depletion of available soil water (ASW)), fertilizer levels of control (no fertilizer), AMF inoculation, and nano iron chelate, and plant species of Lallemantia (L. iberica and L. royleana) at the Research Farm of College of Agriculture, Shahed University, Tehran, Iran, in 2018/2019. Results: The results showed that increasing water deficit stress significantly decreased the above traits while applying...

The purpose of this study was to evaluate the influence of alcoholic and aqueous extracts of few medicinal plants (Fennel, Cichorium, Asafoetida, Echinacea, Balangu (Lady’s mantle and Olender) on growth and development of Alternaria alternata fungi. The experimental treatments were arranged as factorial and the data was analyzed based on a completely randomized design with three replications. The effect of seed and plant extracts, plant type (plant), and their interactions were significant on the fungal growth and development. The strong antifungal properties of aqueous and alcoholic extracts of balangu and oleander showed a broad-spectrum natural antifungal resistance in those plants. However, the results indicated a high resistance for A. alternata against the aqueous extract of fennel. This study concluded a high potential for alcoholic extract of balangu an...

An effective plant-arbuscular mycorrhizal fungi (AMF) symbiosis can improve plant growth and development, especially under drought stress. This study aimed to evaluate the effects of AMF inoculation on the growth, yield, fatty acid compositions, and physiological processes of L. iberica and L. royleana under various irrigation intervals (i.e., irrigation after 30 % (I30), 60 % (I60), and 90 % (I90) of soil available water depletion). The results showed improved growth parameters, seed yield, chlorophyll concentration, stomatal movement, antioxidant enzyme activities, and radical scavenging activity in AMF-inoculated plants in both species compared to control plants (without AMF inoculation). Moreover, the seed of AMF-inoculated plants had higher phosphor uptake, mucilage, and oil content. Interestingly, AMF application modified the profile of seed fatty acids such as eicosenoic, arachidic, linolenic, and linoleic acids. Although water deficit drastically affected control plants, AMF-inoculated plants under I60 treatment showed relatively more incredible performance in both species. On the other hand, inoculated plants showed higher antioxidant activity and less reactive oxygen species accumulation than control plants. The results suggested that irrigation after 60 % of soil available water depletion coupled with AMF inoculation can lead to optimized production of L. iberica and L. royleana in semi-arid environments.

In this study, allelopathic effects of saffron leaf and corm extracts on germination and seedling growth indices of alfalfa (Medicago sativa), arugula (Eruca sativa) and rapeseed (Brassica napus) was investigated in six separate experiments based on completely randomized design. Experimental treatments were consisted of different levels of saffron leaf and corm extracts including 0, 0.75, 1.5, 3 and 6%. The maximum germination percentage of all selected crops was obtained at control treatment (on average 92%) and then decreased with increasing extracts concentration. So that, the germination percentage of arugula, canola and alfalfa in highest concentration of extracts were 18, 10 and 8% for leaf extract and 72, 68 and 93% for corm extract, respectively. The relatively similar trend was observed about germination rate, root and plumule lengths and dry weights. Therefore, the inhibitory effect of saffron leaf extract was more than corm extract on initial growth indices of studied plants. The lowest inhibitory effect of saffron leaf extract and even relatively high stimulatory effect of corm extract were obtained on alfalfa initial growth criteria. Considering the differences in allelochemicals mode of action and concentrations in laboratory bioassays with natural condition, it is necessary to investigate the effects of saffron residues on growth of selected associated crops in greenhouse and field scales for the final decision.
