Selenium (Se) has been recently reported to play a crucial role in ameliorating the negative impact of abiotic stress, including salinity, on several plant species. Two field experiments (2016/17 and 2017/18) were carried out to investigate the possible effect of exogenous Se application at two levels (25, 50 mg L−1) on growth, bulb yield, physio-biochemical attributes, and antioxidant activities of onion grown under saline (5.25 dS m−1) soil condition. Se (25 or 50 mg L−1) foliar application enhanced growth characteristics, as well as membrane stability index (MSI) and relative water content (RWC) as a result of the osmotic adjustment by accumulating more osmoprotectants and enhancing the activity of antioxidants defense system, thus improving photosynthetic efficiency and bulb yield. Proline, glycine betaine, choline, and total soluble sugars content were higher in leaves and bulbs of Se-treated plants under salt stress. Se (25 or 50 mg L−1) significantly increased the activities of enzymatic (ascorbate peroxidase, superoxide dismutase, and catalase) and non-enzymatic (ascorbic acid and glutathione) antioxidants in both leaves and bulbs of salt-stressed onion. Se application at 25–50 mg L−1 may find, in the future, a potential application as anti-abiotic stresses for improving plant growth and productivity under saline soil condition.

This experiment was suggested to study the beneficial effects of foliar application with propolis extract at the rates 0, 6000, 7000, 8000 and 9000 mg/L solution used as foliar application to spinach seedlings on growth, yield and some chemical constituents of spinach plants (Spinacia oleracea L.) grown under calcareous saline soil conditions. All experiments were achieved during the two successive seasons of 2016 and 2017. Results showed that increasing the rates of propolis extract as foliar application increased the growth parameters of the treated plants. The best result was obtained by the rate (8000 mg/L) as a foliar application in both seasons of the study. The same trend was also observed regarding all studied chemical constituents, i.e. chlorophyll a, b and total carotenoids concentration, anthocyanine, total carbohydrates, total and reducing sugars, total free amino acid, free proline, crude protein, total indoles, total phenols, N, P and K in leaves. Thus, the coincident application of propolis extract at (8000 mg/L) as foliar application ingredient is recommended for improving growth, yield and chemical composition of spinach plants and for overcoming the adverse effect of saline conditions.

A field experiments were conducted during the two summer seasons of 2015 and 2016 in saline soil (ECe = 9.0 dSm-1), at Fayoum province, Egypt to study the effect of ascorbic (AsA), as foliar application alone or combined with cyanobacteria (CB) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 54. Treatments comprised 2 ascorbic acid (AsA) levels with or without seed inoculation with cyanobacteria (CB). They were 1 mM AsA, 2 mM AsA, 1 mM AsA + CB and 2 mM AsA + CB in addition to the control treatment in which seeds were not received CB and their plants were sprayed with distilled water. Results could be summarized as follows: increasing the addition of ascorbic acid concentration up to 1Mm with combination of CB increased significantly values of growth attributes (e.i., plant height, of leaves no. /plant, shoot dry weight and leaf area), photosynthetic pigments (chlorophyll a, b and carotenoids), physiological responses (total soluble sugars, proline and soluble phenols) as well as the head diameter, seed yield/ plant, 100 seed weight and seed yield (t ha-1). Also, N, P, K, Fe, Mn, Zn and oil percentage of sunflower seeds with compared to control treatment in both years. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the concentration of ascorbic acid 1Mm combined with CB in both seasons

The 3-year experiment was concerned with the response of spring forms of common wheat (Triticum aestivum L. subsp. aestivum), durum wheat (Triticum durum Desf.) and spelt wheat (Triticum aestivum subsp. spelta L. em. Thell.) to the foliar application of a plant growth stimulant (extract from marine algae Ecklonia maxima), with the commercial name of Kelpak SL (GS), as compared to control treatment (C). The following parameters were analysed: yield of grain, yield components (number of ears, weight of 1000 kernels, number and weight of kernels per ear) and physical indicators of grain quality (test weight, uniformity and vitreosity of grain). The study showed that the level of yielding and the yield components were related primarily with the wheat genotype, but they depended also on the agro-climatic conditions and on the algae extract and control experimental treatments. The application of algae extract, compared to the control, caused a significant increase in the yields of the spring wheat species under study, on average by 7.0%. Canopy spraying with algae extract had a favourable effect on the number of ears, on he number and weight of kernels per ear, but it had no effect on the weight of 1000 kernels. The grain quality of durum wheat, spelt wheat and common wheat was affected more strongly by the weather conditions in the successive years of the study and by the genotype than by the foliar application of algae extract. The spelt genotypes were characterised by lower yields and lower grain quality than common wheat and the durum wheat genotypes.
