The improvement of saline and sodic soils aims to reduce the dissolved salts in the soil solution. In this context, an integrated management approach is required, which not only improves its effectiveness in improving soil properties but also increases water productivity and yields. To mitigate the negative effects of soil salinity, improvement of soil properties and yield –water productivity of rice plant, a field trial was carried out at El-Hamoul region, Kafer El-Sheikh, Egypt, during the summer seasons of 2019 and 2020. The experiments were conducted in split plot design, with three replicates. The main plots were assigned to soil amendments (control, compost (C) 10.0 Mg ha-1, gypsum (G) 100% from gypsum requirement 13.512 Mg ha-1 and G+C).Sub main plots were assigned to foliar application (control (tap water), compost tea (50 L ha-1), proline (3.6 g ha-1), and combination of compost tea + proilne). Generally, results showed that the impacts of main plots were in the following order: compost + gypsum ˃ gypsum ˃ compost ˃ control in both growing seasons. Also, soil amendments had a significant effect on decreasing some soil chemical properties i.e. pH, EC, ESP and increasing of CEC compared control treatment. The treatment compost +gypsum more pronounced the other treatment on soil bulk density and total porosity. Soil basic infiltration rate (IR) and hydraulic conductivity (K) high significantly increased by application of compost, gypsum and gypsum + compost and recorded the highest value by application of compost + gypsum. Chlorophyll, proline content, 1000-grain weight, straw and grain yield of rice were significant increased and recorded the highest values due to the interaction between compost + gypsum and foliar of compost tea and proline during two growing seasons. Water productivity (WP) and productivity of irrigation water (PIW) for grain yield of rice were high significantly increased and recorded the highest values due to the interaction between soil amendments, compost tea and proline. Total return, net return, benefit cost ratio and total return from water unit for rice yield were significant increased with treatment and recorded highest values due the interaction compost + gypsum and foliar application of compost tea and proline.

“…Therefore, plants have evolved diverse endogenous mechanisms for survival in saline environments, including specific regulation of vacuolar loading and stomatal conductance, ion homeostasis, prevention of Na + uptake by roots and shoots, modulation of antioxidant activity, abscisic acid (ABA)‐mediated reduction of transpiration rate, and transcriptional activation of Na + stress response genes (Munns & Mark, 2008; Tabssum et al, 2019). Transporter genes regulate Na + accumulation in rice.…”

Salinity negatively affects plant growth, productivity, and metabolism. Therefore, plants have evolved diverse strategies to survive in saline environments. To identify such strategies involving the ubiquitin/26S proteasome system, we characterized molecular functions of a rice C4HC3 really interesting new gene (RING)-type E3-ubiquitin ligase gene. Oryza sativa RING finger protein v6 (OsRFPv6) was highly expressed under conditions of abiotic stress, induced by 100 mM NaCl and 20% PEG. The GFP-OsRFPv6 protein was localized in the plasma membrane and cytosol in rice protoplasts. In vitro ubiquitin assay revealed that OsRFPv6 possessed E3-ubiquitin ligase activity, but its variant OsRFPv6C100A did not.OsRFPv6-overexpressing plants were insensitive to salinity, but their growth was delayed under normal conditions. Under saline conditions, transgenic plants exhibited higher proline, soluble sugar, and chlorophyll content and lower H 2 O 2 accumulation than wild-type plants. Moreover, transgenic plants exhibited lower Na + uptake, lower Na + content, and higher K + content in the xylem sap assay. Under saline conditions, the expression levels of nine Na + /K + transporter genes in roots and leaves were significantly different between transgenic and wild-type plants. Specifically, under both normal and saline conditions, the expression of OsHKT2;1, a Na + transporter, in the roots of transgenic plants was lower than that in the roots of wild-type plants. These results suggest that OsRFPv6 E3-ubiquitin ligase serves as a positive regulator of salinity response via Na + uptake.

“…For example, Teh et al (2016) [31] applied proline (5 and 10 mM) to 30-day-old rice (Oryza sativa) plants cultivated in vitro under saline stress; the higher concentration significantly increased plant height and shoot and root number when compared to control stressed plants. Additionally, in rice, Tabssum et al (2019) [32] observed improved water relations in salt+proline-treated plants grown in greenhouse conditions, as well as an increase in SOD and CAT activities, indicating an enhanced effect of proline on ROS scavenging when compared to salt-stress conditions. However, 50 mM-proline treatments had adverse effects on bean (Vicia faba), where plant growth and photosynthetic pigment accumulation were similar to that of the sea water treatments [33], indicating toxic effects.…”

Reductions in crop yields brought about by abiotic stress are expected to increase as climate change, and other factors, generate harsher environmental conditions in regions traditionally used for cultivation. Although breeding and genetically modified and edited organisms have generated many varieties with greater abiotic stress tolerance, their practical use depends on lengthy processes, such as biological cycles and legal aspects. On the other hand, a non-genetic approach to improve crop yield in stress conditions involves the exogenous application of natural compounds, including plant metabolites. In this review, we examine the recent literature related to the application of different natural primary (proline, l-tryptophan, glutathione, and citric acid) and secondary (polyols, ascorbic acid, lipoic acid, glycine betaine, α-tocopherol, and melatonin) plant metabolites in improving tolerance to abiotic stress. We focus on drought, saline, heavy metal, and temperature as environmental parameters that are forecast to become more extreme or frequent as the climate continues to alter. The benefits of such applications are often evaluated by measuring their effects on metabolic, biochemical, and morphological parameters in a variety of crop plants, which usually result in improved yields when applied in greenhouse conditions or in the field. As this strategy has proven to be an effective way to raise plant tolerance to abiotic stress, we also discuss the prospect of its widespread implementation in the short term.
