“…Salinity impairs a number of metabolic and physiological functions in plants, such as water absorption, ion homeostasis, respiration, osmotic balance, and protein and nucleic acid synthesis . Salt stress inhibits seed germination and root and shoot growth by limiting the water potential of soil solution, which greatly reduces cell membrane permeability and influx of water to the plant . As noted by Almodares et al , the mechanisms involved in cellular damage in plants under high salt conditions during germination are not fully understood.…”

Research into nanotechnology, an emerging science, has advanced in almost all fields of technology. The aim of the present study was to evaluate the role of nano-silicon dioxide (nano-SiO2 ) in plant resistance to salt stress through improvement of the antioxidant system of squash (Cucurbita pepo L. cv. white bush marrow). Seeds treated with NaCl showed reduced germination percentage, vigor, length, and fresh and dry weights of the roots and shoots. However, nano-SiO2 improved seed germination and growth characteristics by reducing malondialdehyde and hydrogen peroxide levels as well as electrolyte leakage. In addition, application of nano-SiO2 reduced chlorophyll degradation and enhanced the net photosynthetic rate (Pn ), stomatal conductance (gs ), transpiration rate, and water use efficiency. The increase in plant germination and growth characteristics through application of nano-SiO2 might reflect a reduction in oxidative damage as a result of the expression of antioxidant enzymes, such as catalase, peroxidase, superoxide dismutase, glutathione reductase, and ascorbate peroxidase. These results indicate that nano-SiO2 may improve defense mechanisms of plants against salt stress toxicity by augmenting the Pn , gs , transpiration rate, water use efficiency, total chlorophyll, proline, and carbonic anhydrase activity in the leaves of plants.

“…These areas will still have agricultural equipment and expertise, and can continue to be productive by growing drought and heat resistant biomass for use as BECCS feedstock. 9,10 Carbon Capture Will Be Important Carbon capture is needed for two reasons. First, it will be the fastest way to reach net zero carbon emissions.…”

Bioenergy with carbon capture and storage (BECCS) is currently considered a poor choice in climate change mitigation. This is the result of a BECCS application that proposes the use of very large amounts of biomass to offset fossil fuel extraction. A better way to utilize BECCS is proposed. Agricultural waste in the form of crop residues and waste from industrial food production is shown to be a viable feed material for generating renewable energy. This incentivizes food production while also capturing and removing CO2 from the atmosphere. Methods for incorporating agricultural waste into a renewable future are described. It’s proposed that agricultural waste should first be used to produce transportation fuels. After transportation has been moved to renewable electricity and other low carbon energy sources, BECCS can switch to electricity generation in support of wind and solar. A process for using BECCS to remove natural gas from ammonia production is also presented.

“…Some features of degradation can be seen due to soil salinization and drought (Abdel Kawy and Ali, 2012), therefore, the agro-ecosystems adaptation studies have been increased (Hiernaux et al, 2016;Tokatlidis, 2013;El-Ramady et al, 2013;RomoLeon and van Leeuwen, 2016) particularly towards introducing salt and drought tolerant crops as alternatives for traditional grain and fodder crops (Ahmed et al, 2016;Malhotra and Chhabra, 2013;Galvani, 2007). Quinoa (Chenopodium quinoa Willd) has garnered much attention in recent years because it is highly tolerant to soil salinity and drought González et al, 2015).…”

The response of quinoa (Chenopodium quinoa Willd.) grown under salinity stress of irrigation water to nitrogen fertilization for improving yield production and quality was investigated. In plots experiment, application of 0 (N0), 14.28 (N1) and 28.56 (N2) g N m -2 as ammonium sulfate to quinoa (cultivar Regalona) sown in claytextured soil and irrigated by water of 0.65, 10 and 20 dS m -1 was studied. The results showed that application of nitrogen improved both biomass and seed yield. Nitrogen fertilization at rates of 14.28 and 28.56 g m -2 increased the yield of biomass by about 33.5 and 60% more than the control under fresh and 10 dS m -1 saline water irrigation. Under irrigation with 20 dS m -1 , N application by corresponded rates increased the biomass by 57 and 100%, respectively. Similar results were obtained with seed yield. Results of N content in seed and hay indicated that, under non-saline conditions, N content increased by 7.9 and 39.7% in hay and 15.9 and 36.8% in seeds over the control when the plant fertilized by 14.28 and 28.56 g N m -2 , respectively. Seed-N decreased by about 17.0, 5.2 and 8.0% in the plants irrigated with water of 10 dS m -1 and treated by N0, N1 and N2, respectively, whereas irrigation with 20 dS m -1 water decreased seed-N by 26.4, 10.4 and 17.7% in plants fertilized by N0, N1 and N2 respectively. Under nonsaline conditions, nitrogen utilization efficiency (NUtE) decreased from 55.1 to 47.5 and 40.3 kg seed kg -1 N in plants treated byN0, N1and N2. Similar trends were observed in the plants irrigated by higher levels of water salinity. The results indicated that quinoa hay yield responded to N application more than seed yield response. In N0-treated plants, NUtE increased from 55.1 to 66.2 and 74.7 kg seed/kg N in plants irrigated by water of 0.65, 10 and 20 dS m -1 , respectively. N fertilization with N1 and N2 did not influence Na and improved K content in the hay of plants irrigated by saline water (10 and 20 dS m -1 ). The use of quinoa hay as ruminant feed was supported by the results of both organic material content and high levels of crude protein as comparing to clover hay. However, the low percent of ether extract and higher percents of ADF and NDF lowered its quality. Therefore, it could be strong feed supplement for ruminants.
