Yield Responses

A pot experiment was conducted in the greenhouse of the National Research Centre at Dokki, Cairo Egypt during 2010 -2011 winter seasons to evaluate the effect of different salt stress degrees on the growth and yield characters. The salinity treatments were: Irrigation by three concentrations of diluted seawater (2000, 4000 and 6000 ppm) more than the control treatment (irrigated by tap water 250 ppm) and spraying ascorbic acid (AsA) with two concentrations (100, and 200 ppm). Salinity depressed the pods, straw, straw+ pods and seeds weight relative to the control plants but the depression of these traits showed its maximum values when plants subjected to the higher level of salinity (6000 ppm) markedly more than that with the other two levels of salinity. Slight differences in the mentioned characters of plants irrigated by solution contained 2000 or 4000 ppm. Gradual depressions in pods/straw, seeds/pods and seeds/straw ratios were detected with the increase in salt concentration in water of irrigation. Ascorbic acid application led to increase the pod, straw, total and seeds yields. The high increment in pods weight and seeds to straw ratio wereshown by using 100 ppm ascorbic acid but the increment in straw, totalseeds weight and seeds/pods and pods/straw ratios.Furthermore, the absorption rate of N, K, P, Ca, and Mg ions from the growth medium significantly inhibited as a result of treatment with diluted sea water. Meanwhile, significant increases in the uptake of these ions were obtained in response to ascorbic acid application.

1. Two batches of diamondback terrapins have been kept for a whole year, one in sea water the other in tap water, and seasonal variations have been recorded in the composition and osmotic pressure of the blood plasma. 2. All year round the sea-water animals have a higher osmotic pressure and higher concentrations of Na, K, Cl and urea than fresh-water animals. It is in July, however, that these differences are the least marked. 3. The seasonal variations recorded are linked in particular to the conditions of osmotic stress imposed by the environment. 4. The results are discussed within the framework of hibernation and of the evolution among chelonians from fresh water to sea water.

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.

The effects of municipal solid waste (MSW) materials on growth, yield, and mineral element concentrations in tomato (Lycopersicon esculentum Mill.) (1991 and 1992) and squash (Cucurbita maxima Duch. Ex Lam.) (1992 and 1993) were evaluated. Agrisoil compost (composted trash), Eweson compost (co-composted trash and sewage sludge), or Daorganite sludge (chemically and heat-treated sewage sludge) were incorporated into calcareous limestone soil of southern Florida. The control had no MSW material added to the soil. The effect of MSW on crop growth, yield, and mineral element concentrations varied considerably between years for tomato and squash. In 1991, tomato plants grown in soil amended with Eweson or Daorganite had a greater canopy volume than plants in the control treatment. Tomato plants grown in Daorganite had greater total fruit weight (1991) than plants in Agrisoil and more marketable fruit (1992) than control plants. In both years, tomato plants in Agrisoil had higher root Zn concentrations than plants in the other treatments. In 1992, tomato plants in Eweson had lower root Mn concentrations than plants in the other treatments, whereas Mg concentrations in the roots were higher in the Daorganite treatment than in Eweson. Tomato plants in Agrisoil had higher Pb concentrations in the roots than plants in all other treatments. In 1991, leaves of tomato plants in Agrisoil had lower Ca concentrations than leaves of plants in the control treatment. In 1992, leaf Zn concentrations were greater for tomato and squash in Agrisoil than in the control or Daorganite. In 1992, canopy volume and yield of squash were greater for plants in Daorganite than for plants in the control and other MSW treatments. Although canopy volume and total squash fruit weight did not differ among treatments in 1993, plant height was greater for squash plants in the MSW treatments than for those in the control. In 1993, leaf Mg concentrations were greater for squash grown in Daorganite than for plants in the control or Agrisoil. In 1993, fruit Cd concentration was higher for plants with Eweson than for plants in the control or Agrisoil. However, the fruit Cd concentration in squash grown in Eweson compost (1.0 mg/kg dry weight) was far below a hazardous level for human consumption. Our results indicate that amending calcareous soils with MSW materials can increase growth and yield of tomato and squash with negligible increases in heavy metal concentrations in fruit.

In a one-year vegetation pot experiment we compared the effect of the digestate from a biogas plant and mineral fertilisers on yield and quality parameters of kohlrabi, variety Moravia. Four treatments were used in the trial: 1) untreated control, 2) urea, 3) digestate, 4) urea, triple super phosphate, KCl, MgSO4. The rate of N was the same in treatments 2–4, i.e. 1.5 g N/pot. In treatment 4 the rate of P, K and Mg corresponded with the rate of these nutrients in the digestate treatment (3). The inhibited growth of kohlrabi after the application of NPKMg (4) was obviously the consequence of early planting after the application of fertilisers (5 days) and of the salinity of the small content of soil in the pot and resulted in the lowest weight of single bulbs (69 g), followed by the unfertilised control treatment (75 g). After the application of the digestate (treatment 3) the weight of single bulbs significantly increased (126 g) compared to the urea treatment (101 g) and all the other treatments. The content of ascorbic acid in the fertilised treatments did not differ (441–458 mg/kg) but it increased significantly compared to the unfertilised treatment (398 mg/kg). There were significant differences among all the fertilised treatments (1–2–3–4) in the bulb nitrate content (346–1,147–815–1,091 mg NO3−/kg fresh matter, respectively). After digestate application their content decreased significantly to 815 mg NO3−/kg fresh matter. Digestate treatment resulted in comparable or better yields and qualitative parameters compared to all the other treatments.

The experiment was conducted to find out the effects of hydropriming on seed germination, seedling growth and yield of bitter. Two single factor experiments were conduced at the laboratory and field of Seed Science and Technology Department following completely randomized design with three replications and randomized complete block design with five replications, rspectively. The experiments comprised six soaking treatments viz. T0: untreated (control), T1: tap water (around 25º ± 2º C) for overnight, T2:cold water (12ºC) for 5 min, T3: cold water (12ºC) for 10min, T4:cold water (12ºC) for 15min, T5: hot water (45ºC) for 5 min and T6: hot water (45ºC) for 10min soaking. The highest germination (88.0%) was obtained from T5 treatment and the lowest germination  (30.0%) was recorded in control treatment. It was also observed that T5 treatment exehibited superior performances in respect of most of the parameters studied in the laboratory as well as in fiield experiment as compeared to control treatment. In respect of fruit yield per plant, maximum number of fruits obtained from T5 treatment (16 fruits/plant) followed by T6 (14 fruit/plant), T1 (12 fruit/plant), T2 (12.0 fruit/plant), T3 (11.2 fruit/plant) and T4 (11.2 fruit/plant) and the minimum number of fruits per plant recorded from the control treatment (7.6). From the findings of these study it can be concluded that bitter gourd seeds soaked in hot water at 45ºC for 5 min could improve seed germination, expedite seedling growth and eventually increase the yield of fruit.

Field Emergence

An experiment conducted in pots under field conditions in the fall seasons of 2017 and 2018 at the College of Agricultural Engineering Sciences, University of Baghdad, to improve the field emergence in sorghum, in which three factors were studied. 1st factor was the variety (three varieties: Inqath, Rabeh and Buhoth70). 2nd factor was priming treatment (unprimed seed and primed seed soaked for 12 hours in a solution containing 300 + 70 ml L-1 of gibberellic and salicylic acids, respectively). 3rd factor was saline stress (tap water as control (1.26), 6, 9 and 12 dS m-1). RCBD design was used with four replicates. The results showed that Buhoth70 cultivar exceeded the others; also the primed seed exceeded the unprimed seed in the traits of the first and final count of emergence, daily emergence rate, emergence energy, emergence rate index and emergence index in both seasons. The control treatment was superior in the above traits, while the values of these traits decreased as the saline increased, and no emergence accrued at the highest concentration (12 dS m-1) in both seasons. The cultivars varied in their ability to withstand salt stress at the same stress level, and that the seed priming treatment has improved their performance to withstand salt stress compared to the unprimed in both seasons. It can conclude that there is a role for genotype and seed priming in improving seedling performance to tolerate salt stress.

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

ABSTRACT Vegetal mulching can mitigate the harmful effects of salts present in irrigation water. This study aimed to evaluate the effect of irrigation water salinity and mulching on the growth and yield of beet crops. The experiment was conducted in a greenhouse at Redenção, Ceará State. The experimental design was completely randomized in a 2 × 4 factorial scheme, with five replicates, composed of two levels of electrical conductivity of irrigation water - ECw: tap water - 0.3 dS m-1 and saline solution - 5.8 dS m-1; and four types of mulching (rice hulls, carnauba bagana, crop residues, and a control treatment without soil cover). The use of vegetal mulching, mitigated the effects of irrigation with saline water on the variables plant height, leaf area, stem diameter, and tuberous root. The increase of the salt concentration in irrigation water negatively affected the number of leaves, length of the tuberous root, and yield. But, it increased the soluble solids in the beet crop.

Capsicum annum is one of the most cultivated summer crops in Egypt which is consider the most susceptible crop to harsh a biotic stresses as Salinity condition. Pots experiment was carried out at Faculty of Agriculture, Fayoum University, Egypt during two successive summer seasons of 2014 and 2015 to study the responsive of Sweet pepper (cv. California wonder) plants irrigated by diluted sea water (EC= 8.0 dSm-1) to foliar applications of 1 mM alpha-Tocopherol (α TOC). Four treatments were arranged in a randomized block design:1) plants irrigated by sea water (SW) and sprayed by tap water (TW), 2) TW for irrigation and α TOC for foliar spray, 3) SW for irrigation and α TOC for foliar spray and 4) the control (TW for irrigation and foliar spray). Pepper plants irrigated by sea water recognized significant reductions in growth parameters (leave number, leaf area, plant dry weight, Fruit number and Fruit yield). Results also showed that, foliar application of pepper plant with αTOC caused a notable upgrading in growth and yield under saline conditions. The maximum increased growth was obtained when plants irrigated by TW and sprayed by 1 mM αTOC. The foliar application of αTOC considerably boosted the activities of Superoxide dismutase (SOD), Catalase (CAT), Ascorbate peroxidase (APX) and Glutathione reductase (GR) of pepper plants contrasted to control treatment. The outcome of present experiment could be recommended for both new reclaimed lands suffering from salt water and regions exposure to salinity hazard in irrigated water.
