“…The obtained results are in harmony with the findings of (Ibrahim et al, 2021). They stated that the spraying of snap beans (Phaseolus vulgaris L.) with folic acid at the concentrations of 50, 100 and 150 µM/l raised obviously the yield, total soluble solids, protein, proline, free amino acids, total soluble sugars, antioxidant enzymes.…”

This study was performed during 2019 and 2020 seasons on seven years old “Flame seedless” grape trees (Vitis vinefera L.). The trees were cultivated at 3 meters apart between rows and 2 meters between trees in the same row in a calcareous soil under drip irrigation system in a private orchard located at Nubaria, Beheira governorate, Egypt. The trees were sprayed three times, before flowering, during the full bloom and three weeks later with the following treatments: Control spray with water only, Fulvic acid at 1000, 1500 and 2000 ppm, Folic acid (vitamin B9) at 100, 150 and 200 ppm, Seaweed extract at 2000, 3000 and 4000 ppm. Besides, the combinations of 1000 ppm Fulvic acid +100 ppm Folic acid+ 2000 ppm Seaweed extract, 1500 ppm Fulvic acid + 150 ppm Folic acid + 3000 ppm Seaweed extract and 2000 ppm Fulvic acid + 200 ppm Folic acid + 4000 ppm Seaweed extract were also applied. The obtained results demonstrated that the foliar spray of Folic acid, Fulvic acid and Seaweed extract and their combinations improved weight, length, width, size and number of clusters. Furthermore, they also increased extremely weight of 100 berries and consequently the yield per vine in kg and the yield in ton per hectare, weight of juice, the percentages of total sugars, and total soluble solids as compared to control in the two seasons. The effect of Fulvic acid on the previous mentioned parameters was higher than the effect of Seaweed extractor Folic acid and its effect was better by the increasing the applied concentration where the best one was 2000 ppm, which gave the best results more than the other applied treatments in the two seasons. The best combination was Fulvic acid 2000 ppm + Folic acid at 200 ppm + Seaweed extract 4000 ppm.

“…Such agricultural malpractices have to lead to the continuous addition of excess toxic salts to soil, rendering the productive lands a saline wasteland. It has been estimated that 5–7% of the global land and approximately 20% of irrigated land areas are affected by high salinity [ 8 , 9 , 10 ]. Salinity stress proved to be detrimental to the growth and development of existing crops through induction of aberrations in physiological and biochemical processes, including chlorophyll synthesis, photosynthesis, respiration, and ion homeostasis [ 11 , 12 , 13 ].…”

Salinity stress is one of the major environmental constraints responsible for a reduction in agricultural productivity. This study investigated the effect of exogenously applied nitric oxide (NO) (50 μM and 100 μM) in protecting wheat plants from NaCl-induced oxidative damage by modulating protective mechanisms, including osmolyte accumulation and the antioxidant system. Exogenously sourced NO proved effective in ameliorating the deleterious effects of salinity on the growth parameters studied. NO was beneficial in improving the photosynthetic efficiency, stomatal conductance, and chlorophyll content in normal and NaCl-treated wheat plants. Moreover, NO-treated plants maintained a greater accumulation of proline and soluble sugars, leading to higher relative water content maintenance. Exogenous-sourced NO at both concentrations up-regulated the antioxidant system for averting the NaCl-mediated oxidative damage on membranes. The activity of antioxidant enzymes increased the protection of membrane structural and functional integrity and photosynthetic efficiency. NO application imparted a marked effect on uptake of key mineral elements such as nitrogen (N), potassium (K), and calcium (Ca) with a concomitant reduction in the deleterious ions such as Na+. Greater K and reduced Na uptake in NO-treated plants lead to a considerable decline in the Na/K ratio. Enhancing of salt tolerance by NO was concomitant with an obvious down-regulation in the relative expression of SOS1, NHX1, AQP, and OSM-34, while D2-protein was up-regulated.

“…Coriandrum sativum adopt a unique approach by reducing the secondary branches and LAI as response against water stress regimes due to loss of turgor pressure that reduced the rate of transpiration and affects the metabolic machinery and cell expansion in Coriander sativum plants [82]. Similarly, the number of umbels and umbellets per umbel were also reduced in water stress regimes compared to full irrigation.…”

Climatic variations adversely affect the limited water resources of earth which leads to water stress and influences agricultural production worldwide. Therefore, a novel approach has been introduced to improve the tolerance against water stress in herbaceous nature medicinal plants such as Coriandrum sativum by the usage of nanotechnology (foliar applied nanoparticles of ZnOx) coupled with the application of water deficit irrigation. This is an alternative water saving strategy that proved to be efficient to mitigate the Coriandrum sativum tolerance against water stress regimes for sustainable yield production through the activation of antioxidant system. Thus, the phenomena of green synthesis have been deployed for the formation of Zinc oxide nanoparticles (ZnOx NPs) from the leaf extract of Camellia sinensis L. and zinc acetate dihydrate was used as precursor. Different techniques have been used for the thorough study and confirmation of ZnOx NPs such as UV-vis spectroscopy (UV-vis) X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Elemental dispersive spectroscopy (EDS). The prepared ZnOx NPs exhibit hexagonal wurtzite crystal nature has an average size of 37 nm with high purity. These ZnOx NPs have been further studied for their role in amelioration of water stress tolerance in Coriandrum sativum in a pot experiment. Two levels of water stress regimes were employed, IR75 (moderate) and IR50 (Intense) to evaluate the behavior of plant compared to full irrigation (FI). Results showed that under water stress regimes, the 100 ppm of prepared NPs stimulate the antioxidant system by increasing the activity of catalases (CAT), super oxidases (SOD) and ascorbate peroxidase (APX) enzymes and found the maximum at IR50, while the concentration of malondialdehyde (MDA) decreased due to increase in activity of antioxidative enzymes. Furthermore, chlorophyll content and amount of proline also enhanced by the foliar application of prepared ZnOx NPs under moderate water stress (IR75). The results suggested that all the investigated agronomic attributes significantly increased, including plant biomass and economic yield (EY), compared to non-treated ZnOx NPs plants, except for the number of primary branches and LAI. Further, the 100 ppm of prepared ZnOx NPs have great potential to improve water stress tolerance in Coriandrum sativum by improving the antioxidant enzymes activity that enhance agronomic attributes for high crop productivity that require further research at transcriptomic and genomic level.
