“…The nutrient uptake by plants is affected by several factors such as physiochemical properties, plant type, and soil moisture content (Seiffert et al 1995;Eissa and Roshdy 2018). Data of the present research indicated that reducing the amount of irrigation water minimized the uptake of N, P, and K by 12, 24, and 14%, respectively, in comparison with the normal irrigation, while the spraying of algal extract mitigated the negative effects.…”

“…The foliar application of onion grown under water stress by 9% of algal extract minimized the proline and total phenolics by 40 and 40% and increased the chlorophyll 100% compared to the unsprayed plants. Plants grown under stress minimize the chlorophyll synthesis rate and produce large amounts of phenols and proline (Eissa and Roshdy 2018). Ramya et al (2015) found that the foliar application of algae extracts (at rate of 1.5%) to brinjal (Solanumme longena) increased the chlorophyll content of leaves by 79% compared to the unsprayed plants.…”

Availability of water for food production is a global concern; thus, increasing water productivity has been become a necessary. Deficit irrigation is a good strategy to increase water use efficiency, but it may affect negatively on plant physiology and crop productivity. Little is known about the effect of marine algae extracts on water stress resistance and yield of onion grown on semiarid regions. Therefore, field experiments were conducted in 2018 and 2019 growing seasons to study the effect of foliar application of marine alga (Amphora ovalis) extracts (at rate of 0, 3, 6 or 9%) on onion grown under normal irrigation (80% of available soil water) or water stress (50% of available soil water). The field experiments were laid out in a split-plot design with four replicates. The highest dose of algal extract sprayed on onion grown under water stress significantly (P < 0.05) increased N, P, and K uptake by 116, 113, and 93% compared to the unsprayed plants. The application of 9% algal extract for onion grown under water stress significantly (P < 0.05) increased the bulb yield by 67 and 102%, respectively, in 2018 and 2019 growing seasons. Water stress reduced the chlorophyll production as a result of directing most of plant's energy to produce water-resistant materials such as proline and phenols. Algal extract reduced the negative effects of water stress and caused significant increases in onion growth and yield.

“…Supplying the soil with an adequate amount of nutrients and their uptake by plants is considered proof of the soil capacity and an increase in the use efficiency [50][51][52][53][54][61][62][63][64][65]. The application of BC has many additional benefits for plant nutrient cycling, high retention, leaching reduction, and increased use efficiency, thereby improving soil fertility [35].…”

Corn Cob-Derived Biochar Improves the Growth of Saline-Irrigated Quinoa in Different Orders of Egyptian Soils

Biochar is one of the important recycling methods in sustainable development, as it ensures the transformation of agricultural wastes into fertilizers and conditioners that improve soil properties and fertility. In the current study, corn cob-derived biochar (CB) was used to reduce the negative effects of saline water on quinoa (Chenopodium quinoa cv. Utosaya Q37) grown on Aridisols and Entisols, which are the major soil groups of Egyptian soils. Quinoa plants were cultivated in pot experiment and were irrigated with saline water (EC = 10 dS m−1). The experiment contained three treatments, including control without any treatment, biochar at a rate of 1% (w/w) (BC1), and biochar at a rate of 3% (w/w) (BC3). The findings of the current study showed that BC treatments realized significant effects on soil salinity, pH, soil organic matter (SOM), and plant availability and nutrients’ uptake in the two soils types. BC3 increased the SOM in Entisols and Aridisols by 23 and 44%; moreover, the dry biomass of quinoa plants was ameliorated by 81 and 41%, respectively, compared with the control. Addition of biochar to soil increased the nutrients’ use efficiencies by quinoa plants for the two studied Egyptian soils. Biochar addition caused significant increases in the use efficiency of nitrogen (NUF), phosphorus (PUE), and potassium (KUE) by quinoa plants. BC3 increased NUE, PUE, and KUS by 81, 81, and 80% for Entisols, while these increases were 40, 41, and 42% in the case of Aridisols. Based on the obtained results, the application of corn cob biochar improves the soil quality and alleviates the negative effects of saline irrigation on quinoa plants grown on Aridisols and Entisols Egyptian soils. Biochar can be used as a soil amendment in arid and semi-arid regions to reduce the salinity hazards.

“…The increase in plant output is the ultimate outcome of the availability of growth factors at optimum limits, keeping in mind preserving the integrity of the ecosystem. Nitrogen is an essential nutrient and plants need it in large quantities, therefore, farmers raise fertilizer rates in order to increase the obtained yield, but this leads to environmental damage and a decrease in the efficiency of added nitrogen fertilizer (Griggs et al 2007;Zhao et al 2009;Eissa et al 2013Eissa et al , 2014El-Mahdy et al 2018 Eissa andRoshdy 2018). The obtained results of the present research clearly showed the superiority of controlled-release nitrogen fertilizer (CRNF) over the conventional urea in the doubleseason rice rotation.…”

Controlled-release nitrogen fertilizer (CRNF) can effectively enhance crop yields and raise the efficiency of nitrogen fertilizer in agroecosystems. In the present study, the volatilization of NH3 was determined by airflow enclosure chamber technique after the application of different CRNF rates in double-cropping rice fields in southern China for continuous 3 years. The early and late season rice (ESR and LSR) were cultivated each year. The results showed that the total NH3 volatilization losses ranged from 25 to 56 kg N ha−1 in ESR and from 32 to 61 kg N ha−1 in LSR. The loss of N to the total applied N ranged from 12 to 29% in ESR and from 12 to 27% in LSR. The application of CRNF significantly reduced the cumulative NH3 volatilization losses by 20–43% for ESR and by 20–32% for LSR compared with conventional urea application. CRNF in LSR was less effective to reduce NH3 volatilization than that in ESR. Furthermore, the application of 80% of N rate in the form of CRNF gave higher grain yield and apparent nitrogen recovery efficiency (ANRE) than that of application of 100% of N rate from conventional urea. CRNF can effectively reduce NH3 volatilization, and increase rice yield and ANRE. Considering higher price of CRNF, the application of CRNF at lower (20% applied N) rate than conventional urea in LSR may be a reasonable fertilization strategy for improving N use efficiency, environment effectiveness, and sustaining the development of rice production systems in double-cropping rice.
