Environmental stress is a global threat to provide the world’s food. Drought and salinity are the main threats to agricultural land productivity. This is a challenge in implementing SDGs 2030 as well as an opportunity if we are able to use germplasm to overcome various environmental stresses. Research on 2 varieties of rice Inpari 42 agritan as a comparison variety and varieties Sigupai which is a local variety of Aceh originating from Abdya. This study used a 2x3x6 split plot design with 108 experimental units and 324 experimental pots. There is an interaction between varieties when salinity occurs and salinity level on the growth of rice plants in the vegetative phase and electrical conductivity in soil and water which shows different responses between the Inpari 42 Agritan variety and the Sigupai varieties. On the electrical conductivity of the Sigupai. variety, it was better able to reduce Ec at different levels of salinity and time of occurs in the vegetative phase. Meanwhile, Inpari 42 Agritan is more capable of increasing growth under conditions of increased salinity in the vegetative phase. The local variety Sigupai, the rate of growth reduction is also relatively low compared to that without salinity. This is an opportunity to deal with drought and salinity that can occur anytime and anywhere due to drought, water management and improper fertilization that can occur anywhere. It is a challenge to overcome drought and lowering salinity with the use of local varieties and appropriate agronomic practices.

BackgroundProperly reduced irrigation combined with nitrogen (N) application can be used to improve crop water use efficiency (WUE) in arid regions, but its effect on sugar beet is unknown at present. A two‐year field experiment was conducted to evaluate the effects of N application (N0, 0; N1, 150; N2, 225 kg N ha−1) on the canopy production capacity (CPC), yield and WUE of sugar beet under normal irrigation (W1, 70% of field capacity (FC)) and deficit irrigation (DI) (W2, 50% FC) in the early growth stage (EGS).ResultsThe results showed that the W2 treatment reduced the CPC by reducing gas exchange, leaf area index (LAI) and chlorophyll content (SPAD value) of sugar beet leaves compared to the W1 treatment. However, DI combined with N application increased these parameters. Specifically, N application increased the net photosynthetic rate by 40.7% by increased gas exchange, SPAD and LAI compared to the N0 treatment. In addition, N application increased WUE by 12.5% by increasing thickness of upper surface, stomatal aperture and cross‐sectional area of petiole. This ultimately led to a significant increase in taproot yield (TY; 19.7%) and sugar yield (SY; 57.6%). Although the TY of the N2 treatment was higher than that of the N1 treatment, the SY and WUE did not increase significantly and the harvest index decreased significantly by 9.3%.ConclusionDI combined with 150 kg N ha−1in the EGS of sugar beet increases the WUE in arid areas while avoiding yield loss by improving the CPC. © 2023 Society of Chemical Industry.
