Effect of Different Irrigation Intervals and Foliar Spray with Some Anti-Transpiration on Growth and Productivity of Some Tomato Grown Under Saline Soil Conditions

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

A field experiment was carried out at Khaled Ibn El-waleed village, Sahl El-Hussinia, El-Sharkia Governorate, Egypt, during two summer seasons 2019 and 2020 to study the effect of NPK nanofertilizers, biofertilizers and humic acid combined with or without mineral fertilizers different at rates on some soil physical properties and soybean productivity and quality under saline soil conditions. The treatments consisted of: NPK-chitosan, NPK-Ca, humic acid, biofertilzer and control (mineral NPK only). In both seasons, the experiment was carried out in a split plot design with three replicates. The results indicated a significant increase in the soybean yield parameters as compared to control. There was also a significant increase in dry and water stable aggregates in all treatments as compared to control. The treatment NPK-Chitosan was the best in improving dry and stable aggregates. Also, hydraulic conductivity and total porosity values were significantly increased in all treatments due to increase in soil aggregation and porosity that led to increase in values of hydraulic conductivity. Values of bulk density were decreased, the lowest values of bulk density were found in NPK-chitosan treatment as a result of the high concentration of organic matter resulted from NPK-chitosan is much lighter in weight than the mineral fraction in soils. Accordingly, the increase in the organic fraction decreases the total weight and bulk density of the soil. Concerning soil moisture constants, all treatments significantly increased field capacity and available water compared to control. This increase was due to improvement of the soil aggregates and pores spaces which allowed the free movement of water within the soil thereby, increasing the moisture content at field capacity.

Wheat Leaf

In this study, we quantified the spatial distributions of inorganic ions and sugars contributing to osmotic adjustment and their net deposition rates in the elongating and mature zones of leaf 4 of the main stem of spring wheat (Triticum aestivum L. cv. Lona) during its linear growth phase under saline soil conditions. Plants were grown in growth chambers in soil irrigated/treated with nutrient solution containing either no added or 120 mM NaCl. The sampling was conducted on the 3rd day after emergence of leaf 4 at 3 and 13 h into the 16 h photoperiod. The patterns of spatial distributions of total osmoticum, cation, anion and sugar contents (mmol kg-1 H2O) were distinct and were affected by salinity. The total osmoticum content in the region between 0 and 60 mm above the leaf base differed between the two harvests at 120 mM NaCl. Net deposition rates of total osmotica, cations, anions, and sugars (mmol kg-1 H2O h-1) in both treatments increased from the base of the leaf to the most actively elongating location and then decreased near the end of the elongation zone. Contributions of cations, anions, and sugars to osmotic adjustment varied with distance from the leaf base, and were about 21–30, 15–21, and 13%, respectively, in the elongation zone. We suggest that the accumulation of solutes under saline conditions occurs both by increasing the net deposition rate of osmotica and by reducing growth.

Australian species germinate under the combination of environmental conditions where the potential for survival is enhanced. Most species also have dormancy mechanisms that prevent all seeds from germinating in any particular rainfall event. Immaturity of the embryo prevents some species from germinating until environmental parameters change to more favourable conditions. Seed-coat inhibitors may also delay germination, with some seed requiring ingestion and dispersal by animals or a series of rainfall cycles to facilitate germination. Adaptations to fire include germination mechanisms facilitated by impervious seed coats, seed-coat inhibitors and biochemical sensing of water-soluble components of smoke and the high soil nitrate levels found following the burning of vegetation. Germination is generally limited under saline soil conditions until rainfall dilutes concentrations to near-zero water potentials. Australian species tend to germinate under temperatures that approximate the rainfall season in their native habitat. Light sensing by Australian species ensures germination takes place only near the surface for some species or only under complete burial conditions in others. More recent research has emphasised the interaction of multiple and sequential cues to relieve dormancy and initiate germination. Knowledge of germination mechanisms provides a basis for better land management, enriched conservation, improved rehabilitation and advanced horticulture, forestry and farming practices.
