RCBD design with three Replications was used. Results showed that highest average of leaf length, dry percentage of Vegtative growth, Chlorophyll percentage, roots length, root diameter, dry weight of roots for Both cultivars due to the irrigation with the magenetized water with 1000 Gausses reached up to (14.95cm, % 28.90, % 42.98, % 2.98). However there was a signification increase in treatment on mucilage percentage in leaves and roots reached up to (2.85, 1.02)% compare with control treatment. The highest percentage of dry weight leaf and root, Chlorophyll percentage and mucilage percentage of leaf and root at Yellow queen reached up to (28.24%, 42.40%, 2.72%, 5.70mm, 2.91gm 0.94%).

The effect of saline magnetized water irrigation on seed germination and seedling growth of wheat cultivar Iraq were studied. Irrigation water was supplemented with different levels of Sodium chloride 6, 12 or 18 mmhos/ cm in addition control treatment, and passed through a proper magnetic felid with 1000, 1250, 1500 or 2000 gaus in addition control treatment. The results showed significantly stimulated shoot development and led to the increase of germination, seedling emergence, area leaf, length of shoot and root and fresh and dry weight compared to the controls. Results also showed significant interaction between saline water and magnetized water. So, using magnetic treatment of saline water could be a promising technique for Agricultural improvement.

Two pots experiments were conducted at the Experimental Farm of El-Qassasin Horticultural Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during two successive seasons of 2016/2017 – 2017/2018, to investigate the effect of potassium silicate at (0, 4, 6, and 8 cm3/l) as a foliar spray under different levels of water salinity (tap water, 1000, 2000 and 3000 ppm) on Calendula officinalis L. plant. The experiment was performed in complete randomized block design as factorial experiment with 3 replicates. The obtained results cleared that using salinity levels decreased growth parameters (plant height, number of branches/plant, fresh and dry weights of herb/plant), flowering parameters (flower diameter, number of flowers/plant, fresh and dry weight of flowers (g/plant) during eight cuts and fresh and dry weight of flowers (g/plant/season)) and chemical constituents (chlorophyll a, chlorophyll b, carbohydrate and carotenoid contents) compared to control. Moreover, the highest values in these parameters were registered by potassium silicate at 8 cm3/l concentration. Proline content increased in leaves with using saline water at 3000 ppm + potassium silicate at 8 cm3/l. Generally, it could be concluded that potassium silicate at 8 cm3/l, showed a uniform impact in alleviating inhibition of Calendula officinallis L. plant growth and productivity under moderate salinity stress condition.

To explore the effects of 6-Benzylaminopurine (BAP) on leaf characteristics and grain yield of aromatic rice the present investigation was carried out. The experimental materials comprising four concentrations of BAP (0 ppm, 30 ppm, 60 ppm and 90 ppm) and three aromatic rice cultivars (Chinigura, Kataribhog and Kalijira). The experiment was laid out in randomized complete block design and replicated thrice. Statistical analysis indicated that leaf characteristics and grain yield of aromatic rice were significantly influenced by the concentrations of BAP. Leaf number, leaf length, leaf breadth, leaf dry weight, panicle length, 500-grain weight and grain yield were increased with the increasing concentration of BAP. Among the concentrations, the 90 ppm of BAP performed better regarding the parameters studied. Maximum number of leaf, longest leaf, maximum leaf dry weight, highest length breadth ratio of leaf and maximum 500-grain weight was observed in Kataribhog which was statistically at par with that of Kalijira. Broader leaf was observed in Chinigura, whereas longest panicle and highest grain yield was recorded from Kalijira. Among different treatment combinations the highest grain yield (4.10 t ha-1) was recorded from Kalijira × 90 ppm BAP treatment and the lowest grain yield (3.08 t ha-1) was recorded from Chinigura × control treatment.

ABSTRACT There is interest in increasing the yield and pigment content of beetroot and red beet since conventional agronomic practices or breeding efforts have not produced satisfactory results. Using a local cultivar of red beet (Beta vulgaris L. subsp. cicla) as the model plant, pot experiments were established to determine the effects of proline and tyrosine (used as plant growth regulators and for synthesis of beetroot pigments) on growth and yield and pigment (carotenoids and chlorophyll) levels in leaves. Proline or tyrosine at 100 and 200 mg·L-1 increased plant height, number of leaves, fresh and dry weight of leaves and roots, root/shoot ratio, and root diameter and length while a higher concentration (400 mg·L-1) increased some parameters but decreased others. Any proline concentration resulted in more leaf carotenoids and chlorophyll and higher carbohydrate content in leaves and roots than the controls, and tyrosine was more effective than proline. Tyrosine and proline proved to be successful agents in improving growth and yield characters of beet plants, especially at 100 mg·L-1 and 200 mg·L-1. Beetroot growers can effectively use these two amino acids as a foliar application to increase yield for edible purposes and to increase pigments for extraction for use in coloring and medicinal industries.

Background: Using ornamental plants for phytoremediation of Heavy Metals (HMs) in soil environments has been grown due to its cost-effectiveness and ease of use in urban environments. The aim of this study was to assess the potential use of Calendula officinalis for soil Copper (Cu) phytoremediation in the presence of different types of chelating agents (Ethylene Diamine Tetra-Acetic Acid (EDTA), Citric acid (CIT), and Tartaric Acids (TAR)) at different levels of Cu in a calcareous soil. Methods: To investigate the effects of stress caused by the use of chelating agents on biochemical changes of C. officinalis, the activity of some antioxidants of C. officinalis (Superoxide Dismutase (SOD), Catalase (CAT), Ascorbate Peroxidase (APX), Peroxidase (POD), and Polyphenol Oxidase (PPO)) was evaluated. Results: As results, C. officinalis showed an increase in shoot and root Cu concentration in the presence of all chelating agents compared to the control. The highest accumulation of Cu in the root/shoot was observed in EDTA-treated plants. However, an increased Cu level in plant parts (due to consuming of EDTA) was corresponded to lower dry weight in shoot and root; higher H2O2 and malondialdehyde (MDA) contents, and antioxidant activity (APX, PPO, CAT, SOD, and POD) in plants compared to the control treatment. On the contrary, the application of CIT and TAR primarily increased shoot and root dry weight and Cu concentration. Conclusion: Generally, the results of this study could be suggested that plants possess a well-organized resistance mechanism against oxidative stress caused by using of CIT and TAR.

Calendula officinalis L. plants were fertilized with urea (46% N), ammonium nitrate (31% N), and ammonium sulfate (20% N) at 0, 25, 50, or 100 kg N/Feddan (4200 m2). The plants also received calcium superphosphate (15.5% P2O5) and potassium sulfate (48% K2O) at 100 and 50 kg/Feddan, respectively. The results showed that fertilizers enhanced vegetative growth and improved flowering aspects compared to control plants. Application of urea at 50 kg N/Feddan gave the highest flower number (119) and flower dry weight (183 g). Moreover, the applied fertilizers increased the content of photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids) in leaves and flowers and the N percentage in shoots. Nevertheless, P and K percentages were decreased.

A Study was conducted the effect of saline water irrigation with different levels of NaCl (6, 12, 18) Decisemins/M in addition with the control treatment. The saline water magnetized through a proper magnetic field with (1000, 1250, 1500, 2000) gaus in addition control treatment. Seed germination, seedling emergence and seedling growth of Alletiffia wheat cultivar were investigated. The result indicated significant increasing in most character studies such as, seed germination, seedling emergence, shoot and root length, fresh and dry weight of shoot, root, and leaf area. On the other hand, all character studies were significantly decreased when used saline irrigation water. The result also showed significant interaction between the magnetized water and saline water which used in irrigation pots in most characters studies.
