“…From the previous data we can mention that, potassium silicate leads to reduce the harmful effect of water salinity. These results were in harmony with those obtained by Hussein and Nesreen (2014). Fresh weights of leaves, stem and roots (g/plant): Data presented in Table (4) reveal that, irrigation water salinity significantly decreased fresh weights of leaves, stem and roots g/plant.…”

A field experiment was carried out at the Experimental Farm in Faculty of Agriculture, Suez Canal University, Ismailia Governorate, Egypt, to study the effect of saline irrigation water, potassium silicate and their interaction treatments on growth and chemical contents of Eucalyptus camaldulensis Dehn. seedlings during the two successive seasons of 2013 and 2014. The seedlings were irrigated with tap water (control) one month after transplanting two times/week. The saline irrigation water was prepared from seawater obtained from Suez Canal in Ismailia region, included five treatments (control (tap water), 3000, 6000, 9000 and 12000 ppm),. Plants were irrigated with the treatments twice/week during 10 month starting 1 month after planting at the rate of 5 liters per plant. Seedlings were sprayed with potassium silicate levels (0, 2, 4, 6 and 8 cm 3 /l) one time every month during 10 months. The results showed that, vegetative growth characters (percent of plant height and stem diameter increment, fresh and dry weights of leaves, stem and roots/plant), chemical contents in the leaves (N, P, K, chlorophyll a, b and carotenoids) and some physical properties of wood [specific gravity (g/ml), lignin % and fiber length (mm)] were decreased with the high rates of saline irrigation water, but raised with the highest concentration of potassium silicate. However, the relative water content (RWC), sodium and proline contents in the leaves were increased by increasing the concentration of saline irrigation water but decreased when using the high rate of potassium silicate. The results revealed that, potassium silicate application alleviates the detrimental effect of salinity stress on vegetative growth, chemical content and physical properties of wood in this study.

“…dry matter, uptake of N, P, K, Na and Ca, and yield of cotton as reported by Hussein et al . [17], who added that Na/K ratio increased as salt concentration increased in contrast to Ca/(Na + K) ratio that showed the opposite response. Also, salt stress results in a depression in plant height, root length, branch number, fresh and DW of shoots and roots of moringa [18,19].…”

To investigate the effect of nano-zinc fertilizer on growth, yield and mineral status of cotton plants grown under salt stress, a pot experiment was set up in the greenhouse of the National Research Centre. The treatments were as follows: (I) diluted seawater: 10% (S1), 20% (S2) and tap water as a control (S0), (II) 100 ppm (NZn1), 200 ppm (NZn2) nano-zinc and distilled water as a control (NZn0). Irrigation with 10 and 20% seawater decreased dry weight (DW) of leaves by 11.53 and 43.22%, while decreases in bolls were 15.50 and 71.65%, respectively. Except for root DW and top/root ratio, the measured growth parameters were increased as nano-zinc concentration increased. As for the interaction between treatments, the highest DW of stem, leaves and bolls resulted from the addition of NZn2 under normal condition, followed by NZn2 x S1 and the next was NZn2 x S2. The foliar application of 200 ppm nano-Zn led to mitigating the adverse effect of salinity and confirmed that diluted seawater could be used in the irrigation of cotton plant. However, phosphorus fertilizer should be added with nano-Zn application to avoid P/Zn imbalance. Some elements’ status and their ratios were recorded.

Application of antioxidant materials like absicisic acid to alleviate salinity stress and promote cotton growth is high effectiveness target, whereas cotton plant is an attractive industrial crop. Pot experiment was conducted to evaluate the effect of salinity stress and absicisic acid (antioxidant materials to alleviate salinity stress) on cotton growth and macro nutrients status in shoots of cotton plants. Plants subjected to two salinity levels (2500 and 5000 ppm as diluted sea water), and tap water (250ppm) as control, sprayed absicisic acid (ABA) with two concentrations (20 and 40 ppm of ABA) and distilled water as a control. Salinity decreased stem and leaves dry weight compare to the control treatment. The lower concentrations of ABA (20 and 40 ppm as a foliar spray) improve dry weight of stem and leaves. Reversely, leaves/stem ratio decreased with both concentrations of the absicisic acid. The increment in dry weight of leaves and stem or their sum showed its higher values by application 40 ppm from ABA under the 5000 ppm salinity level and also under fresh water treatment but under the 2500 ppm treatment the highest values were by 20 ppm of growth regulator. Nevertheless, L/S ratio decreased by ABA treatment, whereas, the high concentration of ABA (40ppm) was super than lower concentration (20ppm) under both salinity levels. Generally, it can be used diluted seawater in irrigation of cotton plant with spraying abscisic acid to alleviate the harmful effect of salinity.
